The world often feels harsh, yet countless everyday delights trace their roots back to moments of intense hardship. In this roundup of 10 popular innovations, we uncover how tragedy, war, and oppression unintentionally gave rise to treats, gadgets, and cultural phenomena we now cherish.

10 popular innovations Shaped by Suffering

10 The Tragedies Of The Great Depression And World War II Gave Us The Bliss Of The Twinkie

Much like the famed snack itself, Hostess managed to survive far longer than anyone expected during the bleak years of the Great Depression. While most firms were teetering on the edge of collapse, Hostess clung to a narrow window of operation.

James Dewar originally crafted a short‑cake filled with fresh strawberries, but those berries were only available for roughly two months each year. When the economy crumbled, staying open merely sixty days annually proved unsustainable.

To stay afloat, they swapped the seasonal strawberries for a fruit that could be sourced year‑round: bananas. The resulting banana‑filled cake became wildly popular and earned the nickname “Twinkies.”

However, America’s entry into World War II brought a banana ration, forcing Hostess to search for yet another filling. During the war, they turned to vanilla‑flavored cream.

What began as a stop‑gap measure turned into a permanent change; the vanilla‑filled Twinkie outsold its banana predecessor, and even after the banana ration lifted, the company never reverted.

9 The Power Chord Was Invented Because A Soldier Lost His Lung In The Korean War

Every rock‑and‑roll anthem leans on the power chord, a sonic building block heard in everything from AC/DC to Nirvana. Its legacy can be traced straight back to Link Wray’s groundbreaking 1958 instrumental “Rumble.”

Wray had once dreamed of a singing career, but the Korean War interrupted his plans. The harsh jungle environment exposed him to a slew of diseases.

Like many of his comrades, he contracted a severe bout of tuberculosis that ultimately required the removal of one lung.

Deprived of his vocal ambitions, Wray turned his focus to the guitar, inventing a gritty, overdriven sound that would become the cornerstone of the power chord.

His forced pivot gave birth to a musical staple that would shape generations of punk, metal, and rock musicians, ensuring his impact far outlived the battlefield injury.

8 Sunlamps Were Originally For Dying World War I Orphans

After World I, Germany’s economy lay in ruins, leaving the civilian population severely malnourished. Food scarcity meant that adults and returning soldiers received the bulk of what little remained, leaving children especially vulnerable.

Massive numbers of youngsters developed rickets, a disease caused by deficiencies in vitamin D, calcium, and phosphate. At the time, doctors had no clear understanding of the condition’s cause.

Physician Kurt Huldschinsky observed that the afflicted children were unusually pale and hypothesized that ultraviolet light might help. He built a lamp emitting UV radiation, and the children’s health dramatically improved.

Huldschinsky commercialized the device as a “sunlamp,” a prototype that would later inspire the modern tanning bed, granting generations of celebrities and politicians a fashionable, albeit radioactive, glow.

7 The First Bicycle Came After A Horse Apocalypse

In 1816, the eruption of Mount Tambora unleashed a catastrophic ash cloud that killed roughly 4,600 people instantly and caused a further 10,000 deaths in the ensuing weeks. By the end of the year, the disaster claimed about 90,000 lives worldwide.

The eruption’s fallout darkened the sky over Europe for months, devastating oat crops that fed draft horses. As the grain withered, thousands of horses perished, and the survivors became too costly to maintain for impoverished farmers.

With their primary mode of transport gone, people were forced to seek alternatives that didn’t rely on animal feed. Inventor Karl Drais von Sauerbronn responded by creating a foot‑propelled “dandy‑horse,” the earliest personal bicycle.

The dandy‑horse, named after the now‑absent equine labor, marked the birth of human‑powered personal transportation, paving the way for the modern bicycle we know today.

6 The Civil War Made Tabasco Sauce, And Reconstruction Made It Popular

In the 1850s, Edmund McIlhenny thrived as a banker, but the Civil War ruined his fortunes, leaving him bankrupt. He retreated to his in‑laws’ home on Avery Island, Louisiana.

Unbeknownst to him, the island sat atop a massive salt deposit. McIlhenny mined the salt and sold it to the Confederacy, generating a lucrative wartime income. Union forces later targeted the salt mine, burning his farm twice.

Fleeing the danger, his family escaped to Texas. When McIlhenny returned after the war, his attempts to cultivate a garden failed on the scorched, saline soil.

In New Orleans, a veteran shared Mexican pepper seeds with him. Using those seeds, McIlhenny produced the first bottle of Tabasco sauce.

The fiery condiment quickly gained traction during Reconstruction, adding much‑needed flavor to the bland fare of the era. Today, it remains a staple on tables worldwide.

5 Hip‑Hop Owes A Lot To Robert Kennedy’s Assassination

The tragic and untimely death of Robert Kennedy sent shockwaves through 1960s politics, but its ripple effects reached an unexpected arena: hip‑hop culture.

In 1968, campaign aide Michael Viner joined Kennedy’s team and met former football star Rosey Grier, who was working security for the candidate. Grier famously wrestled the gun from Sirhan Sirhan’s hand.

Both men planned to continue political work in Washington, but Kennedy’s assassination halted those plans. Instead, they stayed in California and entered the entertainment industry.

Grier acted in, and Viner produced the soundtrack for, the B‑movie “The Thing with Two Heads.” The film’s minor hit “Bongo Rock” sparked Viner’s next venture.

Viner formed the Incredible Bongo Band and recorded a cover of “Apache.” This version became the anthem of early hip‑hop, popularized by DJ Kool Herc during his legendary block parties.

“Apache” provided the first scratchable groove for Grand Wizzard Theodore, birthing turntablism and influencing countless artists—from Afrika Bambaataa to Nas—who sampled the track for decades.

4 The Treadmill Was A Torture Device For Prisoners

In the aftermath of the Napoleonic Wars, England faced a dire labor shortage. Prisons supplied a ready pool of workers, and in 1817 Sir William Cubitt invented the first treadmill—a device more akin to today’s stair‑climber.

Inmates stood on large spokes that turned a massive wheel, converting their steps into mechanical power that crushed grain, pumped water, or drove mills. The relentless motion earned the apparatus its name.

Working the treadmill was excruciating: prisoners were forced to walk for six hours a day, climbing an equivalent of 4,300 metres—nearly half the height of Mount Everest—over a five‑day stretch.

If a worker stopped, the wheel kept turning, causing the inmate to tumble and sustain injuries. Public outcry eventually led to the treadmill’s ban in England as cruel and unusual punishment in 1898, though its modern gym counterpart still feels punishing.

3 Dunking Booths Were A Violent By‑Product Of Segregation

Dunking booths have become a staple of fairs and church carnivals, offering a playful test of strength that ends with a splash. Yet their origins are far darker.

In the late 1800s, a popular attraction called the “African Dodger” challenged participants to throw a baseball at a live Black man’s head protruding from a painted plantation backdrop. Hitting the target earned the thrower a prize.

Over time, carnival owners deemed the practice too cruel and replaced the live participants with wooden “Negro Heads.” The two games eventually merged into the “African Dip,” where striking the target triggered a mechanism that dunked the person into water.

Eventually, the booth evolved into a harmless amusement where anyone could sit in the dunk tank, shedding its violent origins.

2 The Banjo Was Used To Keep Slaves From Dying

The banjo, now synonymous with Appalachian folk, Muppet characters, and Steve Martin’s comedy, actually has a grim genesis rooted in the trans‑Atlantic slave trade.

In the 1600s, slave ships faced a dire problem: many captives fell ill and died en route, threatening the shipowners’ profit margins.

To keep the enslaved labor force healthier, owners encouraged dancing, hoping rhythmic movement would stave off disease. They believed African musical traditions could motivate the slaves, so they introduced stringed instruments resembling the banjo.This instrument made its way to America and, after being showcased in minstrel shows that caricatured enslaved people, the banjo entered mainstream white entertainment, cementing its place in American culture.

1 Cosmetics Come From Mutilated Prisoners

Most of us don’t realize that the anti‑aging miracle known as Retin‑A, a staple in acne treatments and wrinkle creams, owes its existence to grim prison experiments.

The World Health Organization even labels it as one of the most essential medications for a basic health system. Yet its development was anything but benign.

After World II, the Nuremberg Code outlawed human experimentation worldwide—except, it seems, in Philadelphia. From 1951 to 1974, dermatologist Albert Kligman conducted drug trials on inmates at Holmesburg Prison, viewing them as “acres of skin” rather than humans.

Funded by the CIA, Dow Chemical, and Johnson & Johnson, Kligman subjected prisoners to extreme procedures: stripping skin with Scotch tape, pulling fingernails, dousing open wounds with Agent Orange, dosing them with LSD, and even exposing them to radioactive isotopes.

Among the many compounds tested, an early version of Retin‑A emerged, eventually becoming the cornerstone of modern cosmetics.

These experiments claimed countless lives, and the legacy of such cruelty lingers in the products we use daily.

Money has been the driving factor behind some of history’s greatest innovations. Whether tinkering away in labs or risking their lives in a new flying contraption, people can become extremely motivated to solve difficult problems when they know there’s a big prize at the end. The following ten historical challenges illustrate how cash‑laden contests ignited breakthroughs that still shape our world today.

10 Flax‑Spinning Prize

If there was one man who understood that cold, hard cash is a powerful incentive, it was Napoleon. Throughout his reign, he promoted several contests to bolster France’s economy and reduce the country’s dependence on European imports. He awarded 12,000 francs to Nicolas Appert for developing a method of canning food that preserved it longer.

Napoleon reserved his most substantial award for a flax‑spinning machine. In 1810, he announced a prize of 1 million francs to the person who could devise a method of spinning yarn from flax fiber. This was a prize with no time restriction that could have been won by anyone regardless of their country of origin.

The contest lasted until 1813 and received around 80 submissions. Although inventor Philippe de Girard came closest to a working model, he was never officially awarded the prize. In financial trouble, Girard went to Austria where he hoped to gain support and develop a working spinning mill.

In 1817, he returned to France with a working prototype, but Napoleon was no longer in power. When his successors didn’t honor the contest, Girard was forced to sell his patent to England. However, his efforts were recognized posthumously, and his descendants were awarded a pension.

9 Rainhill Trials

One of the defining components of the industrial revolution was steam power, which revolutionized travel. In the 1820s, work began in England on the Liverpool and Manchester Railway (L&MR). It was going to be the first public intercity railway to rely entirely on steam power with no horse‑drawn traffic. It was also going to be a better transportation alternative to canals, which allowed for the carrying of cargo and passengers.

Suffice it to say that the expectations for the railway were significant, but its success was entirely reliant on the locomotive used for the train. It needed to be sturdy and powerful enough to pull its cargo several times a day. In October 1829, the Rainhill Trials were staged to find the best candidate. Five different engines competed on a track that was 1.5 kilometers (1 mi) long.

Besides finishing the course, the locomotives had to adhere to several guidelines. These included using coke as fuel, having two pressure safety valves, and maintaining boiler pressure under 50 pounds‑force per inch. The winner of the race would be awarded a prize of £500.

Determining a winner was fairly easy. Only one locomotive finished the course: the Rocket built by George Stephenson. He won the prize, and his Rocket was used when the L&MR opened in 1830.

Prize money aside, Stephenson became one of the most successful locomotive builders in the decade to come. In England, he is remembered as the “Father of Railways.”

8 Turbine Prize

The industrial era in France was a period that followed a time of turmoil and instability. In order for the country to remain a European economic power that was strong enough to compete with its neighbors, France needed technological advancements to support its growing industries. That is why the French Society for the Encouragement of Industry was born.

One of the society’s first ambitions was to find a better alternative to the waterwheel, something more modern and efficient that could be introduced on a large commercial scale. In 1823, the society established the Turbine Prize—a contest that rewarded the best new design with 6,000 francs.

In 1827, a young engineer named Benoit Fourneyron claimed the prize with his new invention: the water turbine. Based on a design from Claude Burdin, Fourneyron’s invention became the first commercial hydraulic turbine in the world.

Although this 6‑horsepower turbine was impressive for the time, it wasn’t enough for Fourneyron. He used the prize money to continue his research and improve his design.

The end result was the 60‑horsepower Fourneyron turbine, which was completed in 1834. It functioned at 80 percent efficiency and became popular throughout Europe and North America during the industrial era.

7 Schneider Trophy

Jacques Schneider was a 19th‑century French industrialist with a passion for aviation. However, after a severe accident in 1910, he could no longer fly. Undeterred, he used his money to support this new industry by founding the Coupe d’Aviation Maritime Jacques Schneider (aka the Schneider Trophy).

Schneider believed that seaplanes were the future of aviation. In 1912, he announced a series of races over land and sea to determine which country made the best seaplane. The winner would receive the Schneider Trophy and a cash prize worth around £1,000.

The first race took place in 1913. Although several countries expressed interest, only four planes took part, all of them French. The races were time trials, so speed was the key to victory. But the planes also had to cover a certain distance in contact with the sea and sit in water for hours without taking on liquid.

The first race was successful, and another event was scheduled in 1914. This time, several countries participated and England took home the trophy. The country that won three years in a row would keep the Schneider Trophy permanently, and their pilots would receive an additional prize worth 75,000 francs.

Over the next 17 years, there were 10 more races, which were dominated by England, Italy, and the US. The Brits won the trophy permanently in 1931. The average speed of the planes improved from 75 kilometers per hour (45 mph) in 1913 to 550 kilometers per hour (340 mph).

6 Texas Boll Weevil Eradication Prize

The boll weevil is a beetle that is native to Central America. Sometime during the late 19th century, the weevil made its way from Mexico to the US, where it became a major pest because of its fondness for cotton buds and flowers. By the start of the 20th century, the boll weevil was already one of the most devastating blights on American agriculture.

Texas was the first state affected by the weevil. By 1903, the entire eastern part of Texas had suffered crop losses due to boll weevil infestations. People simply didn’t know how to combat the insect.

Recently introduced to the US, the weevil proved resistant to the insecticides and standard pest eradication practices of the day. In 1899, US farmers moved up the crop schedule so that it wouldn’t coincide with the weevil breeding season. However, low temperatures, heavy rainfall, and one of the worst hurricanes in US history derailed that plan.

In 1903, Texas Governor Samuel Lanham announced the Boll Weevil Eradication Prize—a $50,000 reward for the invention of a device or remedy to eradicate the pest. The invention had to be practical enough to be applied on a large scale.

This prize was seen as a desperate act or a stalling tactic. The contest only lasted a few weeks. Despite receiving hundreds of proposals from Texas farmers, none of the entries were seriously considered. The goal was to garner public attention and redirect it to the state’s solutions.

5 Chicago Times‑Herald Motor Prize

In 1895, the Chicago Times‑Herald newspaper had a great idea to boost sales: they would stage the first automobile race in America. The winner would not only make it into the history books but would also receive a $5,000 prize.

The concept of automobiles was so new to Americans that they weren’t even sure what to call them. Part of the Chicago Times‑Herald’s campaign involved coining a word for this new invention.

Suggestions included “horseless carriage,” “automobile,” and “vehicle motor.” But the newspaper settled on “moto cycle” as the winning term. Regardless of whether this was the Times‑Herald’s intention or not, the race did a lot to promote the car in America and spurred an industry in its infancy stages.

The race was originally scheduled for October and was supposed to go from Chicago to Milwaukee. However, it was later postponed to November, and the route was changed to a shorter 90 kilometers (55 mi) from Chicago to Evanston and back again. Even so, only 11 cars took part in the race out of the 80 or so that signed up, and only two of them actually finished the race.

The winner was Frank Duryea, who raced in a car designed and built by him and his brother, Charles. The two of them founded the Duryea Motor Wagon Company just a few months prior to the race.

Based on their success, the Duryea brothers became the first to produce and sell automobiles in the US. Their success was derailed only by a personal rivalry between them.

4 Scientific American Prize

At the start of the 20th century, aviation garnered more interest than any other industry. Many people and organizations supported aviation by offering huge rewards to pioneering pilots.

The $25,000 Orteig Prize went to Charles Lindbergh for the first solo transatlantic flight. William Randolph Hearst offered $50,000 for the first transcontinental flight in less than 30 days. Finally, the Daily Mail offered around $100,000 in prizes for numerous aviation firsts.

Compared to them, the Scientific American Prize seems a bit modest. It was worth $2,500 and went to the first airplane in America to fly straight for 1 kilometer (0.6 mi). Since it was established in 1908, it has the distinction of being the first aviation contest in US history.

Aviation pioneer Glenn Curtiss won it the same year, piloting his iconic plane, the June Bug. He flew it over Pleasant Valley for a distance of over 1,500 meters (5,000 ft). This was 550 meters (1,800 ft) more than necessary. Besides winning the prize, Curtiss also gave us the first pre‑announced, publicly observed flight in America.

Curtiss achieved many aviation firsts and earned numerous rewards in the process. In 1909, he won the Bennett Cup offered by the New York Herald publisher James Gordon Bennett for setting a new speed record of 75 kilometers per hour (47 mph). In 1910, Curtiss won another Scientific American Prize as well as a $10,000 reward offered by the New York World for completing a flight from New York City to Albany.

3 Phylloxera Prize

During the mid‑19th century, France was afflicted by the Great French Wine Blight. A North American aphid known as the grape phylloxera had been mistakenly brought into Europe, and it started wreaking havoc on vineyards. Although the name suggests that France was the only country affected by the blight, vineyards all over Europe were devastated by the aphids.

In 1873, the French government offered a prize of 300,000 francs for a remedy to the grape phylloxera infestation. Hundreds of suggestions poured in. Since they needed to be verified by the Ministry of Agriculture, it took years to test them. By 1876, over 1,000 ideas had been tested, but few showed any promise.

Initially, people didn’t even know what was causing the blight. Although the aphid was introduced to Europe sometime in the early 1860s, it wasn’t until years later that botanist Jules‑Emile Planchon identified it as the source of the problem.

American entomologist Charles Valentine Riley later confirmed Planchon’s theory. Riley also proved that the European aphid and the one in North America were the same.

Eventually, this realization led to the solution. Over the years, American rootstock had grown resistant to grape phylloxera. Two winegrowers named Leo Laliman and Gaston Bazille proposed that European vines grafted to American rootstock would be able to withstand the aphids.

Laliman tried to claim the prize. But the government denied his claim because many people blamed him for being among those who had brought grape phylloxera to Europe in the first place.

2 Sugar Beet Prize

Until the mid‑19th century, sugar was considered a prized resource that was available only to the wealthy. But in a relatively short time, sugar became more accessible on the European market mostly because of Napoleon.

During the Napoleonic Wars, the French leader was faced with a problem. France needed sugar, but England controlled the sugar trade by importing the valuable commodity from sugarcane plantations in the South Pacific.

Eager to minimize France’s dependence on English goods, Napoleon announced a prize of 200,000 francs for an alternate sugar source. The prize actually focused on refining sugar from grapes, which didn’t work well. However, the French did accidentally stumble upon a suitable candidate: the sugar beet.

As the story goes, French scientists brought Napoleon two loaves made with sugar beet in 1811. The emperor was so impressed that he immediately ordered 39,000 hectares of beets to be planted. By 1815, France had 79,000 acres of beets plus hundreds of factories to refine the sugar.

Since the prize was for sugar from grapes, it was never awarded to anyone. Instead, Napoleon used the money to incentivize French farmers to grow sugar beets.

Tobacco farmers were persuaded to change their crops. Cattle farmers were shown how to use sugar beet waste products as cattle feed. Finally, schools that taught the principles of beet cultivation were opened across France. By 1850, sugar became an affordable commodity that was accessible to most of Europe.

1 Magellanic Premium

The Magellanic Premium is a prize that rewards significant contributions to the fields of navigation, astronomy, or natural philosophy. It can be seen as a useful companion to the Nobel Prize because the latter doesn’t cover these areas. But there are some differences.

For starters, the Magellanic Premium is 100 years older. Moreover, winners of this prize don’t receive a cash reward but rather a nice gold medal. Lastly, the Magellanic Premium has no strict schedule. Prizes are awarded only when the need arises. In fact, there have only been 33 recipients of the Magellanic Premium during its 230‑year life span.

Despite rewarding exploration, the prize is not named in honor of Ferdinand Magellan. It is actually named after 18th‑century natural philosopher Jean‑Hyacinthe Magellan who donated 200 guineas to the American Philosophical Society in 1786 to set up the award. The “nuts & bolts” of the prize were then established by Benjamin Franklin, the president of the American Philosophical Society at the time.

In 1790, the first prize was awarded to Francis Hopkinson. This also made the Magellanic Premium the oldest medal in America that was awarded for scientific achievement. A signer of the Declaration of Independence, Hopkinson won the prize for describing a new spring block to assist in sailing.

In 2014, Alar Toomre, an Ethiopian‑American astronomer, won the prize for his simulations of the interactions of galaxies.

In the world of invention, not every breakthrough shines forever. Some ideas sprint onto the scene only to be pulled back by controversy, regulation, or sheer impracticality. Here we dive into the saga of the 10 innovations blacklisted, from high‑tech swimwear that reshaped Olympic pools to a shocking (literally) hangover cure that fizzed out of favor.

Why These 10 Innovations Blacklisted Matter

These ten cases illustrate how the line between genius and overreach can blur, prompting governing bodies, industries, or public opinion to step in. Understanding their stories helps us appreciate the delicate balance between creativity and responsibility.

10 Swimming Super Suits

Swimming super suits surged onto the competitive scene in the late 2000s, promising to rewrite the rules of elite racing. Constructed from ultra‑light, water‑repellent fabrics, the suits claimed to boost buoyancy, trim drag, and catapult swimmers toward record‑breaking velocities.

Their debut sparked a firestorm of debate as world records began to tumble at an unprecedented rate, creating an uneven playing field. The 2008 Beijing Olympics became the poster child for this controversy, with a staggering 25 world records shattered by athletes wearing the cutting‑edge gear.

Amid the excitement, the sport’s governing bodies stepped in. In 2010, FINA—now known as World Aquatics—rolled out strict regulations that capped the technology permissible in competition swimsuits, effectively blacklisting the high‑tech super suits from professional meets.

The ban aimed to restore fairness, ensuring that victory in the pool would hinge on human skill and training rather than the latest textile wizardry. While the suits left an indelible mark on swimming history, their prohibition underscores the fragile equilibrium between innovation and the integrity of sport.

9 Stickum, Aka Sticky Gloves

Coated with a mysterious adhesive called Stickum, a certain brand of football gloves gave receivers a grip that seemed almost supernatural. The extra tack turned once‑impossible catches into routine spectacles, delighting fans and frustrating opponents.

These gloves entered the NFL spotlight in the late 1970s and early ’80s, quickly becoming a secret weapon for many star receivers. Their uncanny ability to secure the ball sparked heated discussions about fairness, sportsmanship, and where the line should be drawn on equipment enhancements.

By 1981, the league drew a hard line, officially banning Stickum from the field. The NFL’s decision highlighted a commitment to a level playing field, emphasizing that no player should gain an unfair advantage through gimmicky gear.

Though consigned to the annals of football lore, Stickum’s legacy lives on as a cautionary tale: even the most game‑changing inventions can be blacklisted when they tip the competitive balance too far.

8 RealNetworks RealDVD

RealDVD promised a bold new way to enjoy movies: a DVD player that not only played discs but also let users create personal digital copies of their collections. Launched in 2008, the device aimed to revolutionize home entertainment by giving consumers unprecedented flexibility.

However, the movie studios—Disney, Paramount, Warner Bros., among others—saw the technology as a direct threat to their copyright protections. They argued that RealDVD facilitated unauthorized copying, sparking a fierce legal battle that culminated in a courtroom defeat for RealNetworks.

In 2009, a court injunction halted the distribution of RealDVD, effectively blacklisting the product. The episode highlighted the razor‑thin line between technological innovation and copyright law, reminding the industry that groundbreaking ideas must also navigate complex legal terrain.

7 Jeff Gordon’s “T‑Rex” Racecar

Jeff Gordon’s “T‑Rex” racecar earned its nickname for good reason: it was a ferocious, rule‑bending beast that dominated NASCAR in 1997. Designed by Gordon’s crew chief Ray Evernham, the car featured aerodynamic tweaks that pushed the envelope of the sport’s regulations.

By exploiting a loophole in the rulebook, the T‑Rex achieved a performance edge that left rivals scrambling. Its aggressive bodywork and innovative engineering made it a formidable contender, quickly becoming the talk of the track.

But NASCAR officials weren’t blind to the advantage. The governing body moved swiftly to ban the car, blacklisting the T‑Rex for its rule‑bending design. The story endures as a testament to how far teams will push the boundaries of innovation—and how quickly the sport will act to preserve fairness.

6 Anchored Putters

Anchored putters introduced a novel approach to golfing: a longer shaft that could be rested against the player’s body, providing extra stability during the stroke. Golfers who struggled with traditional putters hailed the design as a potential game‑changer.

Yet the United States Golf Association (USGA) and the R&A, golf’s global rule‑makers, saw the method as an unfair advantage. In 2016, they enacted a ban on anchoring, effectively blacklisting the technique and forcing players to revert to conventional putting styles.

The ruling sparked a heated debate within the golfing community. Proponents argued that anchoring leveled the playing field for those with putting difficulties, while opponents maintained that it compromised the sport’s traditional integrity. The episode remains a vivid example of innovation colliding with long‑standing rules.

5 Electrified Water: Hangover Cure

During the early 1900s, a curious invention claimed to cure hangovers by passing a mild electric current through drinking water. The concept, dubbed “electrified water,” promised to zap away the throbbing headache and queasy stomach that follow a night of revelry.

Special devices were marketed to transform ordinary water into a charged remedy, offering a swift, seemingly scientific fix for post‑party misery. Enthusiasts swore by its effectiveness, arguing that the electrical charge counteracted alcohol’s lingering effects.

Nevertheless, as medical understanding advanced, the novelty faded. Safer, more proven remedies emerged, and the electrified water concept was left as a quirky footnote—a reminder of how some experimental cures simply don’t stand the test of time.

Today, the story of electrified water serves as a colorful example of how inventive ideas can sometimes stray into the realm of the bizarre, ultimately being blacklisted by progress and common sense.

4 Spring Spokes for Cars

In the dawn of the automotive age, engineers experimented with spring‑spoke wheels—wheels that incorporated springs within the spokes themselves. The design promised a smoother ride, absorbing shocks from uneven road surfaces and delivering greater comfort for passengers.

While the concept sounded ideal for navigating cobblestone streets and rough terrain, reality proved less forgiving. As automobiles grew faster and road infrastructure improved, the spring‑spoke wheels proved impractical, prone to mechanical failures and costly maintenance.

Ultimately, the wheels were blacklisted, not merely for their technical shortcomings but as a lesson in balancing ambitious engineering with real‑world feasibility. Their brief appearance underscores that not every inventive spark ignites lasting change.

3 Incandescent Light Bulb

The incandescent bulb illuminated homes for over a century, becoming an iconic symbol of modernity. Yet its brilliance came at a cost: the bulbs were notoriously energy‑inefficient, converting most electricity into heat rather than light.

In 2007, the United States Congress passed the Energy Independence and Security Act, targeting the phase‑out of incandescent bulbs in favor of energy‑saving LEDs and CFLs. The legislation aimed to slash electricity consumption and reduce carbon footprints worldwide.

Although the bulb’s warm glow holds nostalgic charm, its environmental impact forced governments to blacklist the technology, ushering in a new era of sustainable illumination for a greener future.

2 Tesla’s Death Ray

Nikola Tesla, the visionary inventor, once claimed to have designed a “death ray”—a weapon that could emit powerful energy beams capable of destroying enemy targets. The concept sparked both awe and alarm, hinting at a revolutionary shift in warfare.

Tesla’s theoretical device purported to amplify electromagnetic energy into a focused, destructive beam. Although the idea captured imaginations, the death ray never materialized beyond sketches and speculative discussions.

Over time, the concept faded into myth, with some suggesting secret military projects while others dismissed it as pure science fiction. Regardless, the death ray remains blacklisted as an unrealized, controversial invention that never crossed the threshold into reality.

1 Spray on Hair (Not Blacklisted But Should Be)

Spray‑on hair promises an instant transformation, turning thinning strands into a full‑bodied mane with a single aerosol blast. While the concept sounds like a miracle for those battling hair loss, critics warn it masks deeper issues.

Many products rely on temporary fillers that conceal bald spots rather than address the underlying cause of hair thinning. Some formulas even contain harsh chemicals that could damage existing hair, turning a quick fix into a potential disaster.

Moreover, the trend may reinforce unrealistic beauty standards, encouraging people to hide natural baldness instead of embracing it. As confidence in one’s own look grows, the need for such a superficial solution could diminish.

In short, while spray‑on hair may tempt those seeking immediate results, the industry might be better served by encouraging acceptance of natural hair patterns rather than blacklisting a product that offers only a fleeting illusion.

If you love to explore the cutting edge of culinary creativity, you’re in for a treat—these 10 amazing new food innovations are pushing flavor boundaries, reshaping how we think about meals, and promising to make your taste buds dance.

10 Amazing New Food Innovations Overview

10 A Swiss Chocolatier Has Perfected His Formula For A New ‘Ruby’ Chocolate

For ages we’ve been rotating among the classic chocolate families—milk, dark, white—each with subtle tweaks but essentially the same flavor profile. While the world never seemed to protest this status quo, a subtle shift is now bubbling beneath the surface.

Enter Swiss chocolatier Barry Callebaut, who has engineered an entirely fresh style dubbed “ruby chocolate.” This confection boasts a blush‑pink hue and a surprising tang that teases the palate, pairing sweetness with a faint sour note that isn’t typical of cocoa. After successful trials in Japan and South Korea, the UK will soon see a limited‑edition KitKat featuring this ruby marvel on April 16, 2018.

The secret lies in a patented process that treats a specific cocoa bean before fermentation, yielding a distinct flavor without any genetic modification. Though the formula remains a closely guarded trade secret, Callebaut may eventually license it to larger manufacturers if demand spikes.

9 Based Burgers That Taste And Even ‘Bleed’ Like A Real Meat Patty

When vegans switch their plates, they often find a void where classic comfort foods once lived. A juicy burger with that unmistakable meat‑like experience is especially missed, and most plant‑based attempts fall short of that authentic feel.

Enter a tight‑knit team of food scientists who founded Impossible Foods in Silicon Valley. Their mission: recreate a burger that not only tastes like beef but also looks the part, complete with a “bleeding” effect that mimics real meat juices.

The magic ingredient is beet juice, which provides a vivid red “blood” that oozes from the patty when cooked. Coupled with heme—a molecule found in both plants and animals—this combo delivers a texture and flavor profile that rivals traditional beef.

Today, the Impossible Burger is being tested in select restaurants across New York, San Francisco, and Los Angeles, and the company is hustling to expand its presence so more diners can sink their teeth into a plant‑based patty that truly feels like the real thing.

8 Grapes That Taste Just Like Cotton Candy And Are All Natural

Thanks to clever cross‑breeding, farmers have conjured a grape that delivers the sugary punch of cotton candy without any genetic engineering. These grapes are the product of meticulous hybridization, not lab‑based GMO tricks.

The farmer behind the breakthrough patiently blended various wild grape species until the perfect flavor emerged. The result is a fruit that smells like a carnival treat yet retains the juicy texture of a typical grape.

Now stocked in many grocery aisles, cotton‑candy grapes command a slightly higher price tag, but taste‑testers overwhelmingly agree the novelty and sweetness justify the premium.

Blind tests reveal that even without any prior expectations, most participants correctly identify the unmistakable cotton‑candy flavor, confirming the fruit’s unique appeal.

7 Ice Cream That Is Made Right In Front Of You Using Liquid Nitrogen

A few years ago, a husband‑and‑wife engineering duo wowed the sharks on ABC’s Shark Tank by whipping up ice cream with liquid nitrogen right before the judges’ eyes. All but one shark relished the frosty treat and praised the theatrical flair.

Although the panel loved the concept, they declined to invest, citing concerns over the founders’ franchising strategy rather than the product itself.

Undeterred, the creators of Sub Zero Ice Cream have continued expanding, rolling out franchises across the United States and aiming for a global footprint.

The process is a show‑stopper: liquid nitrogen freezes the mix in seconds, creating a silky texture while eliminating the need for a traditional freezer—an eco‑friendly perk that also cuts energy costs for franchise owners.

For most healthy adults, the occasional serving poses little risk, but awareness is key to avoid unintended health impacts.

1 Deboned Baby Back Rib Steaks That Aren’t A Mishmash

Former NFL defensive lineman Al “Bubba” Baker grew weary of the messy, bone‑laden rib experience that his wife found off‑putting. Determined to keep the meat while eliminating the bones, he patented a process that separates the rib meat cleanly.

After a modest $154,000 in sales, Baker pitched his boneless rib concept on Shark Tank. Daymond John saw potential and facilitated introductions to executives at Hardee’s and Carl’s Jr., landing a multimillion‑dollar deal.

Today, the boneless rib steak appears on menus at Carl’s Jr. and Hardee’s, allowing diners to enjoy a full‑flavored rib without the usual mess, and Baker’s venture has skyrocketed to $16 million in sales within three years.

This clever innovation proves that a simple redesign of a classic favorite can turn a personal solution into a lucrative national product.

When you hear the phrase 10 pivotal innovations, you might picture modern tech, but the roots of many everyday marvels stretch back to ancient Persia. Modern‑day Iran rests atop the ruins of civilizations that pioneered everything from refrigerated storage to the first organized postal system. Let’s dive into the ten groundbreaking contributions that still echo through our daily lives.

10 Pivotal Innovations Overview

10 Refrigeration

Yakhchal, an ingenious Persian refrigeration system dating back to around 400 BC, stands as one of the earliest known methods of cooling. Its design mirrors many functions of today’s refrigerators: a massive mud‑brick dome perched above ground shelters a deep underground chamber where ice, food, and perishables were stored, even under the blistering desert sun. Some of these structures towered up to 60 feet high, showcasing impressive engineering.

The subterranean vaults were lined with a special mortar called s?rooj—a blend of sand, clay, egg whites, lime, goat hair, and ash—that offered superior insulation. This mixture kept the interior chill, allowing the Persians to preserve goods for extended periods.

Cooling worked on the principle of evaporation: water evaporated, drawing heat away and chilling the surrounding air. In winter, ice harvested from nearby mountains was placed in dedicated ice‑pits, guaranteeing a steady ice supply throughout the hot months.

9 Windmills

Nashtifan, a small village in northeastern Iran, hosts remarkably well‑preserved windmills—known locally as asbads—that first appeared over a millennium ago. These towering structures, roughly 65 feet tall, are among the world’s earliest windmills. Constructed from clay, straw, and wood, they were primarily employed to pump water and grind grain.

Unlike the familiar European horizontal‑axis mills, these Persian examples harnessed wind through a vertical‑axis design, relying on drag rather than lift. Their wooden blades spin on a vertical shaft, converting wind force into mechanical motion.

Today, a dedicated volunteer, Ali Muhammed Etebari, safeguards these historic turbines, ensuring they remain a living testament to ancient ingenuity.

8 Chess

Pinpointing the exact birthplace of chess is tricky—both Persia and India lay claim—but there’s no denying the Persian influence on the game’s spread. Historical accounts describe chess as a rivalry between Indian and Persian intellects, each eager to showcase strategic mastery.

The Persian imprint is evident in the terminology: words like “rukh” (rook) and the phrase “shah mat” (checkmate) trace back to Persian language. These terms have become universal in the chess lexicon.

Archaeologists unearthed some of the earliest surviving chess pieces near the ancient city of Afrasiyab. Ivory figurines resembling Persian “rukhs” were discovered, underscoring Persia’s pivotal role in the game’s early evolution.

7 Battery

During railway construction near Baghdad in 1936, workers uncovered what are now called the Parthian or Baghdad batteries. These artifacts date to the Parthian Empire—roughly 2,000 years ago—when Persia ruled parts of modern Iran and Iraq.

Each battery consists of a clay jar sealed with an asphalt stopper, housing an iron rod encircled by a copper cylinder. When filled with an electrolytic solution such as vinegar, the device produced about 1.1 volts of electricity. The precise purpose remains debated.

One prevailing theory suggests the batteries were used for electroplating—coating metals like silver or gold with a thin layer of another metal—though not all scholars agree on this function.

6 Miniatures

The Persian miniature painting tradition blossomed during the Mongol and Timurid eras, spanning the 13th to 16th centuries. This artistic movement reached its zenith in the 15th century, enriched by Chinese influences carried by Mongol rulers and their artisans.

Miniatures served as vivid illustrations, bringing epic tales to life. Poets and storytellers paired their verses with these intricate images, creating a seamless blend of visual and literary art. Notable works include illustrations for Ferdowsi’s Shahnameh and Nezami’s Khamsa.

The craft gave rise to distinct regional schools—Shiraz, Tabriz, and Herat—each developing its own stylistic nuances while preserving the core Persian aesthetic.

5 Ice Cream

While ice cream is now a global favorite, its earliest incarnation appears to have emerged in Persia around 500 BC. The Persians crafted a frozen delicacy known as bastani, blending grape juice, fruit extracts, and sweeteners into a sorbet‑like treat.

Because of its lavish ingredients and the labor‑intensive preparation, bastani was initially a luxury enjoyed by the elite. The invention of Yakhchals—those ancient refrigeration chambers—allowed the Persians to keep the dessert chilled for extended periods, paving the way for experimentation with flavors and textures.

Thus, the modern ice cream we adore traces part of its lineage to these early Persian innovations, linking ancient culinary art to today’s frozen indulgences.

4 Qanat

The qanat system—an underground water‑harvesting technique—originated in Persia roughly 2,500–3,000 years ago. These gently sloping tunnels tapped mountain aquifers, channeling water downhill to arid plains without the need for pumping.

Iran alone boasts an estimated 50,000 qanats, many still functional despite centuries of use. Sadly, many have fallen into disrepair due to silt accumulation, urban migration, and loss of traditional expertise.

Qanats primarily support irrigation, delivering water to fields via a network of subterranean canals. The technology spread across the region, known by various names such as falaj, khettara, foggara, and karez, underscoring its broad influence.

3 Academic Medicine

The concept of a teaching hospital—where medical practice and education intertwine—finds its roots in the ancient Persian city of Gondishapur. This renowned academy attracted scholars from Greece, India, and the Syriac world, fostering a vibrant exchange of knowledge.

During the Sasanian era (226–652 AD), Gondishapur earned the moniker “city of Hippocrates.” Its curriculum spanned medicine, philosophy, theology, and the sciences, creating a holistic learning environment.

Students there learned through direct mentorship, operating under the supervision of seasoned physicians. This model laid the groundwork for modern academic medicine, where hospitals double as training grounds for future doctors.

2 Mail

Although the British Empire often claims the first postal service, the Achaemenid Persians pioneered an extensive network between 550 and 330 BC. Stretching from Greece in the west to India in the east, this system hinged on the famous Royal Road—a 1,500‑mile artery linking Sardis to the capital Susa.

The Royal Road enabled rapid dispatch of messages via skilled horse‑couriers, making it one of history’s earliest organized mail routes. Its length and efficiency surpassed many later highways, even modern interstates.

Couriers relayed dispatches regardless of weather, ensuring swift communication across the empire. This network was vital for intelligence gathering, decree distribution, and maintaining administrative cohesion throughout Persia’s vast territories.

1 Human Rights

Etched in stone in 539 BC, the Cyrus Cylinder—named after Cyrus the Great—stands as perhaps the world’s first human‑rights charter. Discovered in Babylon in 1879, the cylinder proclaims freedom for slaves, protection for the Jewish populace, and equal treatment for all peoples under Persian rule.

Historians view this decree as a foundational document influencing later milestones such as the Magna Carta, the United States Constitution, and the French Declaration of the Rights of Man and Citizen.

They’re creepy, they’re crawly, and they’re literally everywhere—whether you notice them or not. Yet these eight‑legged wonders have become the muse for a surprising wave of human ingenuity. Below you’ll find 10 human innovations that owe their existence to spider‑inspired science and design.

10 Human Innovations Inspired by Spiders

10 Better Than Band‑Aids: Surgical Tape That Adheres to Wet Surfaces

Chances are you’ve needed a band‑aid, stitches, or medical tape at some point—unless you live in a padded room with no sharp edges and no fingernails (but that’s a whole other list). You’ve probably felt the irritation of tape that slips when it gets wet, forcing you to replace it again and again, which is both maddening and pricey. Enter the spider, ready to rescue your skin.

Researchers at MIT are fine‑tuning a surgical tape that can stick to and seal wounds in seconds by exploiting water the same way spider webs do. This two‑sided adhesive boasts an ultra‑strong bond; tests on pig skin and lungs have been successful. The tape uses polyacrylic acid to soak up water, creating a bond reinforced by gelatin that safely dissolves in the body as the wound heals. No more follow‑up appointments for stitch removal or itchy, adhesive‑induced rashes—just a swift, reliable seal.

9 Step Back, Kevlar: Spider Silk Body Armor

Kevlar may soon become a relic, even though it too was born from spider‑silk inspiration. The lightweight, ultra‑strong polymer used in everything from bullet‑proof vests to sailboat sails pales beside newer derivatives fashioned from that sticky, elastic fiber we all unintentionally step on.

Where it takes 33 layers of Kevlar to stop a .22‑caliber bullet, a fresh material dubbed “Dragon Silk,” harvested from Golden Orb Weaver spiders, halts the same round with just four layers. The U.S. Army has already poured resources into its production, eyeing widespread future use. Millions of spiders have contributed to the current stock, and the effort thanks them for their service.

Meanwhile, Washington University in St. Louis has engineered a bacterial system that spits out a synthetic silk called “polymeric amyloid” fiber. This recombinant silk matches natural spider silk in all key mechanical properties, and researchers aim to push its performance even further. It turns out that clever brains, bacteria, and spiders make a formidable team.

8 Webs Used for Micro‑Imaging: Tiny Dome Lenses

The medical community is falling head‑over‑heels for spider capabilities. At Taiwan’s Tamkang and Yang‑Ming Universities, scientists are crafting minuscule lenses for internal imaging that are roughly the size of a red blood cell—tiny enough to travel wherever blood does.

They achieve this by employing the drag‑line silk of Daddy‑Long‑Legs to frame a web, then drizzling resin over it and baking the assembly in a UV oven. The result is a biocompatible lens capable of nanoscale imaging, offering a less invasive alternative to current technologies. Imagine gaining Spidey‑senses as a side effect!

7 Cheeky Devils!: Spider Venom May Be Better Than Viagra

Men bitten by the notorious Brazilian Wandering Spider have reported an unexpected side effect—persistent, unwanted erections. While we certainly don’t advise seeking out a bite before a date, scientists have isolated toxins from this venom to create a gel that mimics the effect.

The experimental BZ371 gel activates within 20‑30 minutes without any stimulation and appears to last about an hour, all while showing no discernible side effects. It could use a catchier brand name, but the science is solid and the potential market is…well, interesting.

6 Eight Spindly Limbs: Inspiration for More Efficient Robots

Even if a spider’s crawl sends shivers down your spine, you can’t deny its mechanical marvels. If we could replicate their movement, we’d be unstoppable. Humans, with only six legs of limited joint flexibility, fall short—no amount of yoga will give us eight‑legged grace.

Engineers have now fashioned spider‑inspired limbs and joints that give robots greater functionality with fewer components. The result? Lighter, smaller parts with superior mobility, ready for deployment across a host of robotic platforms. It’s a genuine leap forward, and the eight‑legged creatures deserve a high‑five.

5 We Can All Potentially Be Spider‑Man!: Real Web Shooters

Who hasn’t day‑dreamed about shooting webs like the iconic superhero? While most of us keep the fantasy to the bedroom, a South African mechanical engineer and YouTuber named JT has built a prototype that brings the idea a step closer to reality.

His design features metal cylinders linked by a cable studded with tiny hooks that latch onto metal structures. Powered by compressed propane and ignited by a custom mechanism, the device demonstrates that art can indeed be stolen from nature—no matter how unsettling the source. Kudos, JT.

4 Trendy, Functional Spider‑Wear: Sustainable Web‑Inspired Fashion

Let’s face it: fashion can sometimes be over‑the‑top and impractical. Yet the industry is ripe for a green makeover, and spider silk is stepping in.

Bolt Threads pioneered a yeast‑based system that carries a spider‑silk protein gene, fermenting it into a purified protein that can be spun into a textile dubbed MicroSilk. Adidas has already used this hybrid material for a lightweight tennis dress, while AMSilk’s BioSteel has found its way into sneakers. Even airlines are eyeing these ultra‑light fabrics for weight‑saving benefits. Nature‑mimicking fashion is finally saving nature.

3 Poison Can Kill Pain: Tarantula Venom Could Replace Opioids

The opioid crisis has highlighted the dire need for alternative pain treatments. Researchers at the University of Queensland have turned to tarantula venom—specifically from the Chinese Bird Spider—to develop a novel analgesic.

They’ve isolated molecules that can be fashioned into mini‑proteins which wrap around pain‑receptor cells, effectively blocking their activity. So far, animal trials have shown no side effects, offering a promising route toward opioid‑free pain relief.

2 Spider Silk Milk: Goat Genes Manipulated to Produce Spider Silk

Move over, Dr. Frankenstein—modern biomimicry is taking the stage. A company called Nexia has genetically tweaked goat embryos with Golden Orb Weaver silk genes, prompting the animals to secrete spider‑silk proteins alongside their milk.

Spider silk is famed for being as strong as steel yet incredibly flexible. Harnessing this material could revolutionize construction in quake‑prone zones, surgical grafts, and countless other applications. While the silk produced by goats isn’t yet on par with that spun by spiders, the research is advancing steadily.

1 Reflective Webs Can Save Birds: UV‑Reflective Glass

Birds perceive ultraviolet light, a spectrum invisible to humans. When they slam into clear windows, the impact can be loud, startling, and sometimes fatal. Spider webs naturally reflect UV, allowing birds to detect and avoid them.

German glass maker Glaswerke Arnold tapped this insight to create Orinlux Bird Protection Glass, embedding UV‑reflective strands within standard panes. Buildings equipped with this glass report a 75‑90 % drop in bird collisions, while the windows look just like ordinary glass to us. A simple, elegant solution born from spider ingenuity.

0 Spider Music!

Ever wondered what a spider’s web would sound like? MIT’s CAST faculty, together with a Ph.D. student, a department head, a music‑theatre lecturer, and a composer, turned spider‑web construction into a 3‑D audiovisual experience.

The resulting “Spider Canvas” blends eerie visuals with haunting melodies, proving that spider silk can inspire not just engineering feats but also artistic masterpieces. Halloween just got a new soundtrack.

“We’re living in the future,” they say, and the phrase feels truer now than ever. The leap from telegrams to telephones was monumental; the shift from a lone, dimly‑lit room to the ever‑present internet is even more staggering—though many of us still indulge in that solitary glow. While the overall pace of technological progress appears to have eased in recent decades, the surge of fresh inventions emerging today dwarfs any slowdown. This is the top 10 game roundup of the most electrifying breakthroughs poised to rewrite how we live, work, and play.

Science‑fiction fans have long dreamed of phasers, lightsabers, and bolter guns that could turn hunting or home defense into a high‑tech sport. Reality is catching up: Arcflash Labs, a U.S. company, has unveiled the first commercially viable handheld Gauss rifle. This device works like an electromagnetic catapult, using precisely timed magnetic coils to accelerate a steel projectile down the barrel at breakneck speed.

The current model, the GR‑1 Anvil, hurls a steel rod at roughly 200 feet per second, delivering about 75 foot‑pounds of kinetic energy. For a debut product, those numbers are impressive, and they hint at a future where handheld electromagnetic weapons could be as commonplace as conventional firearms—minus the sci‑fi drama.

If you ever found yourself face‑to‑face with a would‑be aggressor while holding one of these, they’d think twice. After all, who wants to tangle with a weapon that makes even “Doom Guy” look tame?

9 #Ultracapacitorevolution

It feels like we’re on the brink of an energy revolution that could rewrite the rules of power storage. Ultracapacitors—those sleek, high‑output energy buffers—might soon eclipse traditional batteries, offering rapid discharge rates that batteries can’t match.

Enter Skeleton Tech, a company pushing curved graphene ultracapacitors into the spotlight. While they don’t yet hold as much energy as lithium‑ion cells, they excel at delivering massive bursts of power. By pairing these ultracapacitors with conventional batteries in electric cars and public transit, manufacturers can off‑load auxiliary systems to the capacitors, freeing up battery capacity for propulsion and shaving weight and space.

With this hybrid approach, vehicles become more efficient, travel farther, and accelerate faster—leaving engineers and even talk‑show hosts like Joe Rogan to wonder what the next big question for humanity will be.

8 Triffids Are Tasty

Remember the 1999 Simpsons episode where Homer concocts a tomato‑tobacco hybrid? It seemed like pure cartoon absurdity—until real‑world horticulturists proved otherwise. In 2013, a UK gardening firm launched the TomTato, a plant that bears both cherry tomatoes and white potatoes on the same stalk.

Since then, DIY gardeners armed with YouTube tutorials have been experimenting with grafting, creating novel crops that could, in theory, help alleviate food scarcity. The process blends precise surgical grafting with botanical know‑how, turning backyards into miniature research labs.

Whether these hybrid veggies become staple foods or mutate into quirky, bitter kumquats that rule the world, the experiment shows that even the most outlandish plant mash‑ups are within reach.

7 Art Meets Fashion Meets Future Tech

High fashion often draws criticism for its extravagance, with many dismissing runway creations as impractical art. Yet, technology is breathing new life into couture. Dutch designer Iris Van Herpen is pioneering 3‑D‑printed garments that fuse AI‑driven design with avant‑garde aesthetics, turning clothing into moving sculptures.

The result? Outfits that shift, reshape, and respond—proof that fashion can evolve alongside, rather than lag behind, cutting‑edge engineering. Her work demonstrates that the runway can be a laboratory, marrying beauty with high‑tech wizardry.

6 Meating Expectations

Meat may be receding from our plates, but the culinary world isn’t losing flavor. Plant‑based alternatives are edging ever closer to mimicking the texture and taste of real meat, sparking debates among carnivores and vegans alike.

Israeli startup RedefineMeat, backed by legendary chef Marco Pierre White, has crafted whole‑cut alternatives from pea protein and beetroot that boast no GMOs, antibiotics, or other industrial additives. Their range—spanning sausages, burgers, and even flank steak—could capture up to 10 % of the global meat market by 2029, promising a future where “bacon‑like” flavor comes from plants.

5 The (Augmented) Realities of War

Military innovation has historically spurred civilian tech breakthroughs, from radio to the internet. Today, the battlefield is set to become an augmented reality arena, thanks to billions of dollars funneled by the U.S. armed forces into immersive heads‑up displays.

Imagine soldiers wearing visors that overlay real‑time data—maps, enemy positions, even live video—directly onto their field of view, much like the HUDs seen in sci‑fi movies. The technology could also project Yelp reviews or sports scores onto the world around you, turning everyday navigation into a data‑rich experience.

While the primary aim is combat efficiency, the same AR systems will inevitably seep into civilian life, reshaping how we interact with our surroundings.

4 Lifting Made Easy

Not every breakthrough needs to be a full‑blown exosuit. Sometimes, a simple harness can revolutionize how we handle heavy loads, reducing strain and preventing back injuries.

Developed by researchers at Harvard, this ergonomic lift‑assist harness lets users pick up to 50 extra pounds without compromising posture. Though it doesn’t look like Neo’s sleek armor, it provides a tangible boost to human strength, potentially enabling scientists to focus on lofty goals—like warp‑drive research—without the nag of back pain.

Think of the possibilities: a physicist finally able to lift and adjust heavy equipment, paving the way for breakthroughs that could take humanity beyond the stars.

3 Fusion. Finally. Maybe.

Fusion power has long been the elusive holy grail of clean energy, promised for decades yet always seeming just out of reach. Recent advances, however, suggest the breakthrough may finally be on the horizon.

In 2021, MIT teamed up with Commonwealth Fusion Systems to create a record‑breaking magnet using high‑temperature superconducting tape. This magnet delivers the intense magnetic fields needed to confine plasma, a critical step toward net‑energy fusion. Their upcoming device, SPARC, aims to achieve a self‑sustaining fusion reaction by 2025.

If successful, fusion could supply virtually limitless power, dwarfing the output of current fossil‑fuel plants and reshaping the global energy landscape forever.

2 From the Depths to the Heights?

Deepfake technology walks a razor‑thin line between creative wonder and potential menace. On one hand, the ability to superimpose any face onto any video raises alarming concerns about misinformation and personal security.

On the other, the tech has found noble uses: in 2019, David Beckham’s likeness was digitally rendered to deliver malaria‑awareness messages in multiple languages, and Samsung’s AI lab animated the Mona Lisa, letting her speak and move. Hospitals also employ deepfakes to generate synthetic patient data, protecting real patient privacy while enabling research.

As the tech matures, society will grapple with its dual nature—balancing innovative applications against the risk of eroding trust in visual media.

1 The Future Is Ours to Fix. Literally.

Beyond gadgets and breakthroughs, a seemingly mundane policy shift could have seismic effects on the tech ecosystem. In late 2021, Apple announced a bold “right‑to‑repair” initiative, granting users access to spare parts and repair manuals previously locked behind corporate walls.

This move hands power back to consumers, challenging the prevailing model of disposable devices and concentrated manufacturer control. By empowering users to fix their own hardware, Apple may inadvertently accelerate a more sustainable, user‑centric future—one where the line between manufacturer and maker blurs.

Such policy changes, though less flashy than lasers or fusion reactors, could be the true catalyst that steers technology toward a more equitable and resilient tomorrow.

Since humanity first learned to fashion tools, our inventive spirit has swung between brilliance and brutality. While many creations have propelled civilization forward, others have revealed a chilling side of our curiosity, turning ingenuity into instruments of horror. In this roundup of the top 10 most unsettling inventions, we’ll explore the stories behind devices that were either deadly by design or turned deadly by consequence. Buckle up for a wild ride through history’s darkest workshops.

top 10 most Gruesome Inventions

10 Gas Resistant Strollers

In England during the late 1930s, a bizarre contraption called the “Gas‑Proof Pram” emerged from the looming threat of mustard and chlorine gas attacks that had scarred World War I and were feared anew under the Nazi regime. Crafted by F.W. Mills of Kent, these strollers featured a sealed lid fitted with a glass panel and a gas‑filter atop the canopy, while a rear‑mounted horn bulb forced stale air out, keeping the infant inside breathable. Though the design was technically sound, the devices never entered mass production, never saw combat, and ultimately faded into obscurity as the feared gas attacks never materialized.

9 The Cotton Gin

Invented by Eli Whitney in 1793 and patented the following year, the cotton gin dramatically accelerated the processing of cotton, turning the crop into America’s “white gold.” By swiftly separating fibers from seeds, the machine slashed labor demands on the plant itself, yet it did nothing to ease the arduous task of harvesting. The surge in cotton production sparked an exponential rise in slave labor throughout the Southern states. In 1790, only six states practiced slavery; by 1860 that number swelled to fifteen. Between 1790 and 1808, over 80,000 enslaved Africans were imported, and by the Civil War era roughly one‑third of the Southern population was African‑American. The cotton gin’s efficiency thus became the catalyst for the bloodiest conflict in U.S. history, the Civil War, which claimed at least half a million lives and left a million more wounded.

This chain reaction—from a simple mechanical marvel to a nation‑splitting war—underscores how an invention intended to ease labor can, paradoxically, intensify human suffering on an unprecedented scale.

8 Bat Bombs

Pennsylvania dentist Lytle S. Adams was vacationing in Carlsbad Caverns when news of Pearl Harbor’s attack arrived on December 7, 1941. Inspired by the millions of bats roosting in the caverns, Adams proposed a wildly inventive retaliation: attach tiny incendiary devices to tens of thousands of Mexican free‑tailed bats and release them over Japanese cities, which were built largely of wood and thatch. By January 12, 1942, he had presented his plan to Washington, dubbing the project “Project X‑Ray.” The Army’s National Research Defense Committee approved a demonstration, and the Marines later poured two million dollars into development.

However, as the Manhattan Project advanced and the atomic bomb loomed, the bat bomb program was abandoned, sparing both the bats and countless civilians from a night of chaotic fires. The episode remains a testament to the extremes of wartime ingenuity.

7 Urban Baby Window Cages

Imagine a sweltering summer in 1922, perched on a 30‑story apartment balcony with no air‑conditioning and elevators that felt like death traps. One desperate mother, seeking relief for her overheated infant, recalled a peculiar parenting treatise titled “Mental Floss,” which advocated “airing out” children to “renew and purify their blood.” The result? A handful of entrepreneurs marketed metal cages bolted to skyscraper windows, essentially turning babies into human chicken coops. These contraptions exposed infants to bird droppings, hail, and the terrifying possibility of a loose bolt. Unsurprisingly, they never caught on, and the notion of dangling a child from a high‑rise window quickly faded into a cautionary footnote of history.

6 Hydrogen Blimps

Hydrogen‑filled airships, or blimps, represented a daring but perilous chapter in transportation. Unlike modern vehicles that encase volatile fuels within protective tanks, these dirigibles relied on a highly flammable gas for lift. The most infamous disaster, the Hindenburg’s fiery demise in 1937, epitomized the inherent danger. Between August 5, 1908, and May 6, 1937, twenty‑two hydrogen airships crashed and burned—averaging three‑quarters of a vessel per year. Nazi Germany, denied affordable helium by the United States, persisted with hydrogen, leading to repeated crashes during fueling, take‑off, flight, docking, and even combat. Today, all blimps are required to use inert helium, acknowledging the lethal legacy of their hydrogen predecessors.

These statistics highlight how a seemingly elegant solution—lifting a massive frame with a light gas—proved catastrophically unsafe, prompting engineers to abandon the concept for passenger travel.

What were they thinking?

5 The Shoe‑Fitting Fluoroscope

In the early 1920s, Dr. Jacob Lowe showcased a “shoe‑fitting fluoroscope” at retail conventions in Boston and Milwaukee, touting X‑ray technology as a means to ensure perfectly sized footwear. Parents, anxious about ill‑fitting shoes, flocked to the machines, unaware that a 20‑second exposure delivered roughly 13 roentgens (0.13 Sv). Even the less powerful British “Pedoscopes” emitted dangerous radiation. The scattered X‑rays irradiated not only the child’s feet but also nearby shoppers and sales staff, some of whom accumulated a full year’s worth of exposure in just two hours. Reported injuries ranged from dermatitis and ulcerations to burns requiring amputation and basal cell carcinoma. After decades of harm, the devices were finally banned in 1970, marking a belated acknowledgment of their deadly side effects.

4 The Brazen Bull

In ancient Greece, the tyrant Phalaris of Acragas commissioned a bronze statue of a bull, designed by the artisan Perillos between 570 and 554 BC, to serve as a terrifying execution device. The hollow bull housed a victim who, once a fire roared beneath, was roasted alive while steam and smoke escaped through the animal’s nose. To mask the smell of burning flesh, incense was placed inside, and a network of tubes distorted the victim’s screams into animalistic noises. Ironically, Phalaris tested the contraption by forcing its creator inside, only to release him briefly before hurling him down a steep incline, where he perished. Later, Phalaris himself met a grim fate, being burned within his own bull after his overthrow—a grim example of poetic justice.

3 The Tricho System

Marketed by London‑born Max Kaiser starting in 1914, the “Tricho System” boasted award‑winning status after winning a grand prize at the 1925 Paris Exposition. The device employed direct X‑ray beams to permanently remove unwanted facial hair, with clients typically undergoing around twenty treatments. While the technology promised smooth results, repeated or high‑dose exposure caused severe side effects: keratoses, pigmentation changes, ulcerations, tissue atrophy, carcinomas, and even death. Medical journals documented these ailments well into the 1940s, prompting the American Medical Association to issue warnings. The Tricho System’s persistence mirrors other hazardous inventions—hydrogen, lead, and radiation—showcasing how dangerous technologies can linger long after their risks become evident.

This episode underscores a recurring theme: society’s sluggish response to harmful innovations, be they toxic chemicals, radioactive devices, or hazardous gases, often leaves countless victims in its wake.

2 Agent Orange

Originally formulated to boost soybean yields, the herbicide blend known as Agent Orange—comprising roughly equal parts of dichlorophenoxyacetic acid and trichlorophenoxyacetic acid, laced with the carcinogenic dioxin tetrachlorodibenzo‑p‑dioxin—was weaponized during the Vietnam War. Under “Operation Ranch Hand,” U.S. forces sprayed more than twenty million gallons of herbicides over Laos, Vietnam, and Cambodia from 1961 to 1971, defoliating over 4.5 million acres. The dioxin‑laden mixture caused a cascade of health crises: rashes, birth defects, neurological disorders, psychological trauma, and various cancers. Vietnam estimates that 400,000 citizens were maimed or killed, 500,000 children were born with defects, and up to two million people suffered illness linked to the chemical’s lingering toxicity.

1 The Radium Girls

“Look, honey! A watch that glows in the dark!” That dazzling promise lured countless consumers in the early 20th century, but behind the glow lay a lethal secret. In 1916, a New Jersey factory began hiring young women—dubbed the “Radium Girls”—to paint watch dials with radium‑laden phosphorescent paint. To achieve a fine brush tip, workers were instructed to moisten their brushes with their lips, inadvertently ingesting radium daily. The element, mistaken by the body for calcium, accumulated in bone tissue, causing radiation‑induced necrosis, severe jaw degradation (“radium jaw”), and heightened cancer risk.

These women, assured by their employers that the paint was safe, soon suffered excruciating symptoms: toothaches, fatigue, and, in the case of 22‑year‑old Mollie Maggia, a shattered jaw that had to be removed. Despite initial misdiagnoses—her death certificate falsely listed syphilis—the true cause was radium poisoning. Their courageous legal battles eventually forced new labor protections and heightened awareness of occupational hazards, leaving a lasting legacy for worker safety.

Their story illustrates how a seemingly wondrous invention can turn deadly when ignorance, profit, and negligence converge, reminding us that progress must always be tempered with responsibility.

Although the approaches vary, most invisibility technology techniques bend light around objects so that the objects can no longer be seen. The technology isn’t exactly new, but it is in more or less constant flux, with the latest innovations in material design and application occurring relatively frequently. Nevertheless, serious challenges remain, and much of the work presently underway concerns finding solutions to the technology’s current limitations. This list reveals ten of the incredible innovations in invisibility technology.

10 Rochester University Cloak

Joseph Choi’s Rochester Cloak doesn’t render objects completely invisible, but it does have a couple of advantages over more sophisticated devices. First, it’s less expensive and more practical. The Rochester cloak uses four standard achromatic lenses with two different focal lengths, all of which can be bought at a typical optics store.

Together, the lenses narrow a beam of light between one lens and the next before the beam widens again, filling the following lens. As a result, a doughnut shape is created around the tightest focal point. Any object or objects occupying the space around the lens’s center point become invisible. A video demonstrating the Rochester cloak in action is quite impressive, indeed.^[1]

9 Invisibility Shield

Most invisibility devices are pricey, but thanks to a Kickstarter campaign in April 2022, the Invisibility Shield set buyers back only about $65 for a small size (12.2 x 8.3 inches or 31 x 21 centimeters). The full-size shield, measuring 37.4 x 25.6 inches (95 x 65 centimeters), costs $389. Unfortunately, the shields will have almost certainly sold out by now. However, as the campaign demonstrated, invisibility devices need not be only for the wealthy few; the shield, if mass-produced, should be well within most people’s means.

The device, manufactured by Invisibility Shield Company, diffuses light with a set of upright] lenses, so observers see a reflection of objects to their left and right rather than what’s directly in front of them. The effect can be a bit patchy looking, though. According to the company, it’s best to use the shield in an area with a “uniform background, such as foliage, sand, the sky, or asphalt,” so that the shield’s view matches the surrounding area.^[2]

8 Nanoscale Cloak

Inspired by both her love of Harry Potter and fencing, a sport in which slashing and poking one’s opponent is possible, Northwestern student Julia Abelsky, who majored in both math and statistics, developed her nanoscale invisibility cloak. According to a Campus Life article concerning the inventor, Abelsky’s cloak is made of “a diblock copolymer that mimics the unusual refractive properties of the mineral calcite.”

Abelsky uses an analogy to explain how her device cloaks objects. She mimicked the way that water flows around a boulder in a river by directing a stream of light particles around objects. Since the diverted particles no longer strike the object, they cannot bounce back or refract from the object and hit our eyes. As a result, we do not see the object; it becomes invisible to us.

Invisibility has multiple practical applications, not only for the military but also for radar, deep-sea sensors, super lenses, and, possibly, the development of “high-powered glasses” that would enable people who are currently considered too blind to see.^[3]

7 Bare-Bones Invisibility Demonstration

Kelli Kinzig, the manager of Education Experiences at Marvel’s Universe of Super Heroes exhibit at the Center of Science and Industry (COSI) in Columbus, Ohio, talked to a local news station’s meteorologist through COSI’s demonstration of invisibility. The equipment was commonplace and inexpensive: vegetable oil, a pair of tongs, protective gloves, two glass beakers, and a small glass flask, with the last two items being transparent.

Kinzig explained that objects are visible due to light’s reflection (bouncing back from an object to the eye) and refraction (bending away from an object). By immersing the small flask in a beaker of vegetable oil, she rendered the beaker invisible, except for its markings indicating volume levels. Next, she set the smaller beaker full of vegetable oil into a larger one filled with the same substance, and the smaller beaker also vanished, except for its markings.

Kinzig explained that the combined abilities of the beakers and the vegetable oil to refract light eliminated “the refraction and the reflection” and made the object inside the beakers seem to disappear.” The markings on the flask and the smaller beaker, remaining visible, made it clear to viewers that the glassware itself had disappeared—or seemed to have done so.

Although the demonstration was low-tech, it did employ an invisibility cloak of sorts. It exemplified the principles by which much more sophisticated invisibility cloaks function, helping young visitors to the exhibit grasp the science of invisibility.^[4]

6 Quantum Stealth Cloak

Canada’s Hyperstealth Biotechnology is going beyond camouflage as a means of concealing soldiers on the battlefield. Now, the company is making not only troops but also tanks, aircraft, and ships invisible using a patented “Quantum Stealth” material.

Like most other stealth technology techniques, this process works by bending light around objects, but with the advantage that it needs no power source and is both paper-thin and inexpensive. A broadband invisibility cloak works as effectively with “ultraviolet, infrared, or shortwave infrared light.” A video demonstrates the product’s effectiveness.^[5]

5 Thinner Invisibility Cloak

When it comes to invisibility, the thinner the cloak, the better. Nia Brown’s article on a cloak made of metamaterials explains why. Such engineered materials are designed to distort perception but can also “interact with various types of electromagnetic radiation in a way that natural materials cannot.” Since thicker materials are bulkier than the objects they are intended to conceal and less reflective than thinner ones, the object to be hidden appears darker than its surroundings, which actually emphasizes the object’s presence.

The “single layer sheet of Teflon-containing ceramics” developed by electrical engineers at the University of California, San Diego (USCD) makes whatever it covers look completely flat and eliminates the stark contrast in intensity between the covered object and its surroundings, thereby controlling light reflection.

As Boubacar Kanté, a professor in the Department of Electrical and Computer Engineering at the UCSD Jacobs School of Engineering, puts it, “Using this technology, we can do more than make things invisible. We can change the way light waves are being reflected at will.” In the future, such technology will probably allow objects to be rendered completely invisible. Energy and optical communications industries are apt to find such cutting-edge technology indispensable.^[6]

4 Invisible Carpet Cloak

Research concerning invisibility has become international in scope. In Singapore, researchers have successfully hidden a cat and a goldfish in broad daylight. How? A glass wall plays tricks with light, directing illumination away from objects to be hidden. Behind the illusion is what its inventor, Zhang Baile, assistant professor for physics at Nanyang Technological University, refers to as an “invisible carpet cloak” using light-bending Calcite crystals.

Baile’s cloak requires no special conditions. It works well in both air and water and can be used on a large scale. The invisible walls do have limitations, though. The cloak’s ability to make things invisible works “from only six directions” and is bulky and hard to move around. However, the device has potential applications in both thermal management and photon circuits. Baile says he remains committed to furthering innovative invisibility research, and Singapore, the Silicon Valley of Asia, is investing millions in such work.^[7]

3 Active Camouflage Invisibility

In the past, camouflage has been a passive undertaking involving the wearing of uniforms designed to blend with terrain features or draping large objects, such as tanks, in similar material. Now, active camouflage material exists that could conceal personnel and equipment from infrared or visual detection. However, to date, only a few experiments have succeeded in effectively cloaking “objects from precise wavelengths and certain vantage points.”

Active camouflage promises better results. Mimicking the way that such animals as squid and chameleons alter their appearance to match their surroundings, the objects to be hidden seem to change their appearance to match their surroundings. In reality, screens show observers photographs of objects or scenery on the other side of the object. Instead of seeing the object, the viewer sees what the screen displays in its place.

In principle, this technique is effective, but there are a lot of bugs to be worked out. These include too many cameras are needed to capture the 360-degree view required to camouflage an object. Also, the quality of the images obtained can be degraded by resolution limitations and lens distortions. The equipment is heavy and requires a lot of power, and lag time between image transmissions from cameras to screens “can also spoil the effect when the object or its surroundings [is] moving.” Possibly, additional research, new developments in photography and transmission, and lighter equipment can remedy these challenges.^[8]

2 Time Cloak

Most invisibility cloaks work best on stationary objects or objects that exercise limited movement. Not so Cornell University’s time cloak. Imagine that a sequence of action lasting a split second has been inserted into a movie. In watching the film, viewers do not see the inserted material; it’s as though the action sequence is invisible to them.

Researchers at Cornell University did something similar, except that, instead of an action sequence, they used fiber optics to split a beam of light in two. One moves faster, the other slower so that neither of them is visible in the “time lens” created by other beams traveling through the cable. Instead of bending light around an object, as other invisibility cloaks do, the time cloak masks an event in time.

Their work is based on the idea of Martin McCall, a professor of theoretical optics at Imperial College in London, that an event could be hidden in time. City College of New York physicist Michio Kaku, who specializes in the physics of science fiction, said his Cornell colleagues’ science is legitimate. Still, the length of time the object is masked by time is so infinitesimally minute that there’s a long way to go before we have true invisibility, as seen in science fiction. Practical matters also impede development. For example, a machine about 18,600 miles (29,993 kilometers) long would be needed to “make the cloak last a full second,” And this is still not nearly long enough to make an object’s invisibility practical as a means of camouflage.

Still, the technology could have another practical use, although such an application might be something of a double-edged sword. Alexander Gaeta, director of Cornell’s School of Applied and Engineering Physics, and Moti Fridman, a physics researcher at Cornell, agreed that such technology could be used to add “a packet of information to high-speed data unseen without interrupting the flow of information.” But, as Fridman pointed out, such a process might also subject the data to computer viruses.^[9]

1 Metamaterial Devices

Not only large objects, such as glass walls and vast systems of cameras and screens, can bend light. Microscopic devices use metamaterials, specially structured materials with surfaces dotted with holes smaller than the width of visible light waves. These materials are also capable of smoothly shuttling “light rays around them.” Metamaterials can produce seemingly magical effects, agrees physicist Ulf Leonhardt of Scotland’s University of St. Andrew.

Tests of a prototypical woven fishnet of silver nanowires, each one about 10,000 times thinner than a human hair, were found to bend “red light from all angles hundreds of times more effectively” than in past attempts. A second such device, relying on 21 stacked grids of silver and magnesium fluoride of similarly small sizes, bent infrared light.

These findings indicate promising applications of this light-bending technology, which not only could produce invisibility effects but could also improve camera function by “shielding lenses from unwanted light frequencies” and enhance cellphone and radio communications by making antennas invisible to noisy electromagnetic waves. The only challenge? Mass-producing the materials on a large scale.^[10]

The Golden Age of Islam refers to a nearly six-centuries-long period of renaissance in the Islamic world, beginning with the foundation of the Abbasid Caliphate in the eighth century and ending with the sack of Baghdad by the Mongols in 1258. It was a time of unprecedented developments in the fields of geometry, medicine, astronomy, philosophy, arts, algebra, and many others, as scholars from across the known world came to Baghdad, Cairo, Cordoba, and other major Islamic cities to practice and hone their crafts.

10. Automatons

Automatons were early designs in robotics and programmable machines, going as far back as ancient Egypt. While European thinkers – especially from the Italian Renaissance era – are usually credited with the development of complex automatons, it was Arabic scientists that first pioneered them. Perhaps the most influential of them was Ismail al-Jazari, also sometimes called the ‘father of medieval robotics’.

Born in 1136 in modern-day Turkey, Al-Jazari’s inventions included complex works of mechanical engineering that could operate all on their own, like an automated peacock, a water-run clock, automatic soap and wine dispensers, and advanced water cranks and pumps to supply water to farmers. His 1206 treatise on automata, The Book of Knowledge of Ingenious Mechanical Devices, influenced scientists and engineers in the Arabic world and beyond for centuries, including Leonardo da Vinci.

9. Automatic Musical Instruments

The Banu Musa were three polymaths living in Baghdad during the ninth century. While each of them specialized in a field of their own, their contributions are still remembered collectively. They were perhaps one of the first few Arabic scientists to build upon the Greek school of mathematics, establishing their own methods for solving classic mathematical and geometrical problems. 

The Banu Musa were also adept at designing automatic mechanical devices, and are credited with the creation of some of the first programmable music devices. Precursors to modern-day music-making machines like sequencers, synthesizers, drum machines, and others, these structures were automatically able to generate a diverse range of melodies – an unprecedented innovation for that time. Their automatic flute player – a humanoid automaton that could play a variety of tunes on the flute – was easily the first programmable machine in history. 

8. Damascus Steel

Damascus steel was a form of steel used in many places throughout medieval times. While it had its origins in a kind of steel from ancient India called wootz steel, it was on the streets of Damascus, Syria that the material really took off. Apart from a unique, dark look that can’t be replicated, the steel was famed for its strength and flexibility, making it especially useful for melee weapons like swords and knives.

Damascus steel was widely used by Islamic armies throughout the Golden Age of Islam, though it also had uses in ornaments and other crafts. Sadly, the formula to produce it has been lost to history, even if we can make other, far-better types of steel and other metals with the technology available today. 

7. Optics

Optics is the study of light, pioneered by such scientists as Johannes Kepler and Isaac Newton during the European Renaissance. Much of their work, however, was built on the discoveries made much earlier. While the study of optics goes as far back as Greek times, it was during the Abbasid era that thinkers really understood the true nature of light. 

Hasan Ibn al-Haytham – one of the most prominent light specialists of the Islamic era – was the first to disprove the Ancient Greek notion that light originates inside the eye. His book, the simply-named Book of Optics, remains an important work in the field of optics, influencing thinkers across the European world and beyond in the coming centuries. 

6. Drug Trials

Clinical trials are now an irreplaceable part of drug testing and approval, though that wasn’t always the case. The idea of testing medicines in controlled experiments before they’re administered to the general public is a relatively-recent development in human history. It could be singularly traced back to Ibn Sina – a 10th century Iranian polymath who first introduced logic and experimentation to the process of drug testing, among a bunch of other medical innovations.

His book – the Canon of Medicine – was so influential that it was taught across Arabic and European schools of medicine until at least the 17th century. Apart from his insights on drugs and clinical trials, Ibn Sina also made seminal contributions to surgery and the development of a wide variety of surgical tools. Sina’s logic-based method influenced many Arabic doctors and scientists in the following years, and his works like Canon provided the basis for what would be one of the greatest ages for the medical sciences in history. 

5. Glass

While glass had existed for thousands of years before the Islamic golden age, it wasn’t until the first glass factories were set up in Syria during the eighth century that glassmaking really turned into a craft of its own. The first clear, colorless varieties of glass showed up in the Arabic world, thanks to innovations and discoveries by prominent thinkers like Abbas Ibn Firnas – the first inventor to come up with a method to produce clear glass from sand. 

Around the same time, another Arabic chemist, Jabir Ibn Hayyan, was working on colored and stained glass. His treatise, The Book of the Hidden Pearl, provided the first known recipes for artificial pearls and other precious stones, along with methods to cut high quality glass into gemstones. Thanks to these advancements in the Arabic world, the first glass factories showed up in Greece by the 11th century.

4. Surgery

The Abbasid era saw many pioneering developments in the science of surgery, thanks to parallel discoveries in other areas of medicine that advanced our overall understanding of the human body. Islamic physicians would study the works of surgeons from earlier eras – especially Ancient Greece – and come up with their own techniques and tools for the procedures. 

While many thinkers, physicians, engineers, and other smart people contributed to this revolution, the most prominent name was that of Abu al Qasim al-Zahrawi, also known as the ‘father of operative surgery’. Born in 936 near Cordoba in Spain, al-Zahrawi pioneered many surgical techniques used by surgeons around the world for centuries to come. His book, al-Tasreef, or the ‘Method of Medicine’, was used as a medical encyclopedia around the world until the 18th century, as it described over 200 surgical instruments and 300 diseases and their treatments. Many of al-Zahrawi’s techniques remained unchanged until the development of modern surgery. 

3. Algebra

Algebra is a broad field of mathematics that deals with symbols of varying values – like x,y, z etc. – and operators like addition, subtraction, multiplication, and others to represent mathematical problems. While equations and variables have been studied in some form by mathematicians in ancient Egypt, Greece, and India, it was only during the Islamic golden age that all that knowledge was compiled in one place, giving birth to modern algebra. 

In fact, the term ‘algebra’ derives directly from the Kitab al-Jabr – a monumental treatise on elementary algebra written by a Persian mathematician called al-Khwarizmi. Apart from providing a new way of solving linear and quadratic equations with abstract variables, he was the first mathematician to work with ancient Indian numerals, modifying and perfecting them into the ten-digit number system we all use today. 

2. Hospitals

While facilities for medical care existed in various forms before the Abbasid era, the modern hospital only showed up in Baghdad during the ninth century. Built in 805 by the vizier to caliph Harun al-Rashid, it was the first documented facility that provided a center for medical care, a place for the sick to rest, a home to take care of the elderly, and a teaching center for aspiring physicians. 

Between the ninth and 10th centuries, many other Islamic hospitals were founded in Baghdad, Egypt, Iran, Tunisia, Mecca and Medina, Spain, and other major regions across the empire. Known as bimaristans, some of them were quite advanced for their time and closely resembled the modern hospital. In Cairo, a hospital founded by the Abbasid governor became the first facility to offer care for the mentally ill. 

1. Paper

Islamic armies first came across paper during the various invasions of Central Asia in the eighth century. Invented in China some time in the first century AD, the material was far superior to anything used in the Arab world before it, including previous rudimentary mediums of writing like papyrus or parchment. Paper could be mass produced with freely-available waste fibers and retained ink for long periods of time, making it an ideal material to fuel the oncoming golden age. 

The permanent nature of the writing made paper immensely useful for imperial and bureaucratic purposes, as it was impervious to forgery or alteration of any kind. By the 10th century, paper mills had sprung up across the Islamic empire – from Persia to Syria to Spain – allowing scientists and thinkers to widely publish and disseminate their ideas across the empire and beyond. Paper was why Islamic libraries usually contained hundreds of thousands of volumes of knowledge, compared to the relatively-modest collections of major empires before it.
