Imagine slipping beneath the waves and stumbling onto a river that flows beneath the ocean’s surface – that’s the kind of mind‑bending wonder the top 10 underwater list delivers. From secret rivers hidden under mighty Amazon waters to a colossal ocean trapped inside Earth’s mantle, these hidden water bodies prove that the planet still has plenty of surprises tucked away beneath the blue.

10 Cenote Angelita

Cenote Angelita, whose name translates to “Little Angel,” is one of the famed cenotes scattered across Mexico’s Yucatán Peninsula. A cenote resembles a sinkhole, but unlike a dry pit, it’s completely filled with water, formed when a fragile limestone ceiling collapses and exposes the groundwater beneath.

This particular cenote hides a striking phenomenon: a salty river swimming at its deepest layer. A dense, invisible boundary called a halocline separates the briny river from the fresh water above, creating a cloud of hydrogen sulfide that looks like a misty veil.

The halocline is so thick that without a torch you can’t see through it, and its toxic gases make it deadly to breathe. Beyond acting as a natural barrier, the halocline also serves as a makeshift seabed for the fresh water, preventing lighter objects that fall in from ever reaching the salty river below.

9 Lake Whillans

Lake Whillans lies hidden beneath the Ross Ice Shelf in western Antarctica. Scientists originally thought it might be between 10 and 25 meters deep, yet the first drilling in January 2013 revealed a surprisingly shallow 2‑meter depth at that spot, suggesting deeper pockets elsewhere.

Water samples drawn from the lake uncovered a thriving community of microbes that have adapted to survive without sunlight, feeding on ancient pollen fossilized for over 34 million years under the ice.

When researchers bored a 730‑meter hole to reach a nearby 10‑meter‑deep pocket, they encountered not only more microbes but also crustaceans and a peculiar, small fish with oversized eyes. The fish’s massive eyes likely help it navigate the perpetual darkness of its icy habitat.

Some of the fish were translucent, allowing a view of internal organs. This lack of coloration is thought to stem from an absence of hemoglobin, the pigment that normally makes blood red, though scientists have yet to confirm whether this represents a brand‑new species.

8 Hamza River

Deep beneath the Amazon River in Brazil, roughly 4,000 meters (13,000 ft) down, lies a massive subterranean river stretching about 5,950 kilometers (3,700 mi). Though shorter than the Amazon itself, this hidden watercourse has earned the informal moniker “Hamza River” in honor of geophysicist Valiya Hamza.

While the Amazon out‑spans the Hamza in length, the underground river dwarfs it in breadth, measuring a minimum of 200 kilometers (125 mi) wide and expanding to a staggering 400 kilometers (250 mi) at its widest point. However, its flow is sluggish, moving only about one million gallons per second compared with the Amazon’s thunderous 35 million gallons per second.

The Hamza’s water barely travels 100 meters (330 ft) each year, prompting some scientists, including Professor Hamza, to question whether it truly qualifies as a river. Its glacially slow pace likely results from seeping through porous rock rather than coursing through an open channel.

7 Denmark Strait Cataract

When you Google “tallest waterfall on Earth,” Angel Falls in Venezuela usually tops the list at 979 meters (3,212 ft). Yet tucked beneath the Atlantic Ocean between Greenland and Iceland lies a far taller cascade – the Denmark Strait Cataract – plunging an astonishing 3,500 meters (11,500 ft) down to the seabed.

This underwater waterfall forms where icy, dense waters of the Greenland Sea clash with the warmer currents of the Irminger Sea. The colder water plunges sharply along the ocean floor, creating a massive, continuous waterfall that then travels southward, eventually rising back to the surface to replace the displaced warm water, perpetuating a never‑ending cycle.

6 Unnamed River Under The Black Sea

Scientists have mapped a hidden river flowing along the floor of the Black Sea. Unlike any ordinary underwater river, this one boasts waterfalls and rapids, and if it were on the surface it would rank as the world’s sixth‑largest river by discharge, moving ten times the volume of Europe’s mighty Rhine.

The river runs up to 35 meters (115 ft) deep and spans roughly one kilometer (0.6 mi) in width, hugging the seabed. Its high salinity prevents the river’s water from mixing with the surrounding sea water, allowing it to retain a distinct identity.

Researchers from the University of Leeds tracked the river for about 60 kilometers (37 mi) using a robotic submarine until it dissipated into the deep ocean, confirming its existence and spectacular underground flow.

5 Nigardsbreen Ice Cave Pond

Ice caves form within glaciers when meltwater carves an entrance, allowing water to travel through the icy mass. While such caves appear in polar regions worldwide, tourists are especially drawn to the spectacular ice caves of Norway and Iceland.

In 2007, explorers discovered a remarkable ice cave inside Norway’s Nigardsbreen glacier. The cave features a spacious chamber standing 8 meters (26 ft) tall and covering an area of roughly 20 by 30 meters (66 × 98 ft). Within this frozen hall sits a tranquil pond, formed when meltwater created an entry point and then pooled beneath the glacier because it had nowhere else to flow.

4 Hot Tub Of Despair

Deep beneath the Gulf of Mexico, about 1,000 meters (3,300 ft) down, lies a dense brine pool ominously nicknamed the Hot Tub of Despair. Geologists believe it formed millions of years ago when the Gulf evaporated, leaving thick salt deposits that later sank and became a liquid pool as seawater returned.

Brine pools are defined by their extreme salt density, so heavy that submersibles can literally “land” on their surface. The Hot Tub of Despair is four times saltier than the surrounding ocean, devoid of oxygen, and saturated with lethal hydrogen sulfide and methane, conditions that spell doom for most marine life.

Fish and crabs that inadvertently wander into the pool rarely escape, and their bodies become remarkably well‑preserved thanks to the high salinity. Yet certain microbes, tube worms, and mussels have evolved to thrive in this hostile environment, making the pool a unique ecological niche.

3 Lake Vostok

In 1990, Russian scientists drilling at Vostok Station in Antarctica stumbled upon a massive lake hidden beneath the ice. Named Lake Vostok after the research outpost, this subglacial lake stretches roughly 240 kilometers (150 mi) long and 50 kilometers (31 mi) wide, holding more than 5,400 cubic kilometers (1,300 mi³) of water.

The lake’s origins remain debated, though most experts agree that volcanic activity melted a thick ice sheet, creating a vast water reservoir. Some propose it formed as early as 30 million years ago, while others argue for a more recent birth only 400,000 years ago. Regardless, scientists suspect it harbors unique life forms that have evolved in isolation.

In February 2012, Russian researchers finally pierced the 3,769‑meter (12,366‑ft) ice cover to retrieve water. A year later they announced the discovery of a novel bacterium, though controversy lingers over whether the microbe truly originated from the lake or was introduced via drilling equipment.

2 Unnamed Lake Under Antarctica

While Lake Vostok holds the title of the largest subglacial lake in Antarctica, satellite data have revealed a second, still‑unnamed lake that ranks just behind it in size. Scientists have never directly observed this lake, but analysis of ice‑surface depressions strongly suggests its presence.

The concealed lake appears ribbon‑shaped, extending roughly 100 kilometers (60 mi) in length and about 10 kilometers (6 mi) across. Its elongated form hints at a network of feeder streams that may stretch over 1,000 kilometers (600 mi), with at least two channels potentially delivering water from the lake out to the ocean.

Future drilling missions aim to breach the ice and sample the lake’s waters, hoping to uncover whether it hosts distinct microorganisms or other life forms unseen elsewhere on Earth.

1 An Ocean Inside The Earth’s Mantle

Earth’s water origins have long puzzled scientists, with many pointing to icy comet impacts. Yet a team led by Steve Jacobsen at Northwestern University proposes that a massive ocean may already reside deep within the planet itself.

Evidence suggests a vast reservoir of water exists about 660 kilometers (410 mi) beneath the crust, nestled in the mantle’s transition zone. This hidden ocean could contain roughly three times the water volume of all the planet’s surface oceans combined.

The water is locked inside a mineral called ringwoodite, and tectonic activity such as earthquakes and volcanic eruptions gradually pump it upward. Researchers believe this deep‑earth ocean helps regulate surface water levels, preventing the world from becoming a water‑covered sphere.

Welcome to our top 10 weird roundup of water’s most mind‑bending feats and facts. From clouds that burst into flame to quantum‑level double liquids, the planet’s most abundant compound never ceases to amaze scientists, meteorologists, and anyone who’s ever wondered why ice floats.

Top 10 Weird Water Wonders Explained

10 Fire Clouds

Flames and water are notorious for not getting along, yet a rare breed of cloud, known as a pyrocumulus, materializes above intense fire events such as wildfires. The most recent spectacle unfolded over Hawaii’s 2018 Kilauea volcano eruption, where these fiery clouds hovered ominously.

Like any dynamic weather system, hot air rises, cools, and condenses into cloud formations. However, pyrocumulus clouds are scarce, making them a challenging subject for atmospheric researchers.

The Kilauea display proved especially odd. While retaining a classic thunderhead silhouette, the clouds chose to form directly over volcanic fissures rather than merely encircling the eruption site—a behavior not typically observed in fire clouds, which usually linger around active lava flows or wildfire perimeters. This proximity to vents adds a volatile ingredient: sulfur dioxide, which can generate acidic rain that harms delicate vegetation. Humans, too, face hazards such as volcanic smog, or “vog,” which can irritate skin and eyes when these clouds amplify the haze surrounding volcanic vents.

9 The Mpemba Effect

The Mpemba effect has puzzled scholars for centuries, catching the attention of Aristotle and Francis Bacon alike. The oddity lies in hot water sometimes freezing faster than its colder counterpart.

Named after Tanzanian high‑schooler Erasto Mpemba, the phenomenon was experimentally confirmed in 1963 when he demonstrated that heated water, placed side‑by‑side with cold water in identical sub‑zero conditions, solidified before the colder sample.

Multiple theories vie to explain this counter‑intuitive behavior. In the 1980s, Polish physicists attempted—and failed—to prove that warmer water might retain fewer heat‑holding gases. A more plausible explanation points to evaporation: as hot water steams, it loses mass, meaning there’s less water to cool. Another factor could involve convection currents: in a container, colder liquid sinks, pushing the warmer layer upward, creating a circulation that accelerates freezing. Yet, the precise mechanism allowing hot water to out‑freeze cold water remains an open scientific mystery.

8 Water Is Native And Extraterrestrial

One of H₂O’s grandest puzzles concerns its origin. For years, researchers debated whether Earth’s oceans arrived via cometary and asteroidal deliveries after the colossal “Giant Impact” that birthed our Moon.

This cataclysmic collision, occurring about 4.5 billion years ago, reshaped the planet. However, a 2018 study revealed that water likely existed on Earth before the impact. By comparing oxygen isotopic signatures in terrestrial and lunar rocks, scientists found striking similarities, implying that Earth already harbored water prior to the Moon‑forming event.

This finding suggests that Earth’s own “water mark” predates the impact, with the planet’s rocks bearing the isotopic imprint of water. Nonetheless, the research also indicated that subsequent asteroid and comet collisions contributed an additional 5–30 percent of Earth’s present‑day water inventory.

7 Pulse Storms

On July 17, 2016, Alabama beach‑goer Rick Geiss captured a bizarre, towering cloud that would later become an internet sensation. The image, featuring a white triangular cone pouring dark rain from a single point, initially sparked skepticism, with some viewers labeling it a hoax.

Weather experts, however, recognized the formation as a genuine pulse storm. Classified as a cumulus congestus—sometimes called a “heaped‑up cloud”—the phenomenon is distinct from typical thunderstorms, which usually arise from cold fronts. Pulse storms, by contrast, are driven solely by intense heat, prompting a rapid updraft that draws massive amounts of water vapor upward, forming the characteristic cone shape.

Within roughly twenty minutes, rain descends from the central updraft tube, then the storm collapses as a downdraft neutralizes the updraft. The entire life cycle of a pulse storm spans merely half an hour, making it a fleeting yet spectacular meteorological event.

6 Snowball Earth

A dramatic hypothesis posits that during the Cryogenian period (710–635 million years ago), Earth entered a global glaciation state dubbed “Snowball Earth.” In this scenario, ice sheets covered not only the continents but also the oceans, encasing the planet in a frozen shell for millions of years.

The mechanism hinges on albedo feedback: extensive ice cover reflects more solar radiation back into space, cooling the planet further, which in turn spawns additional ice—a runaway cooling loop opposite to today’s warming trend.

Compelling evidence includes glacial deposits found near the equator, indicating that ice reached tropical latitudes. While many scientists agree that the Cryogenian witnessed Earth’s most severe glaciation, a faction argues that the planet never became a complete “popsicle.” Their reasoning rests on evidence of weathered rocks formed by liquid water, suggesting intermittent warm periods that allowed meltwater to flow.

Thus, the debate continues: if Earth did experience a true Snowball state, what mechanisms prevented it from freezing solid forever? The answer remains a tantalizing mystery for geologists.

5 The First Modons

Massive oceanic whirlpools, often imagined only in pirate lore, are very real—and they can span hundreds of miles across. These colossal eddies, known as modons when they travel in pairs, were first documented in 2017.

The inaugural pair of modons persisted for six months, journeying across the entire Tasman Sea. Unlike solitary eddies that typically drift westward, these twin vortices spun in opposite directions yet moved eastward at speeds ten times faster than normal currents.

Discovered via satellite imagery, researchers later identified nine additional modons dating back to 1993, with a striking concentration—eight of them—originating near Australia. The exact process by which modons merge remains unclear, but observations reveal that their tails fuse into a single U‑shaped funnel, sustaining the phenomenon for months.

Beyond their sheer spectacle, modons may act as underwater “subways,” rapidly transporting nutrients and marine organisms across vast distances, reshaping oceanic ecosystems.

4 Water Cannot Decide On Density

A 2017 experiment added yet another bizarre quirk to water’s ever‑growing list of oddities. Inspired by the dual‑form nature of ice—where molecules can arrange randomly (high‑density) or in a tidy lattice (low‑density)—scientists wondered whether liquid water might also exhibit a dual‑density character.

Using advanced X‑ray techniques, researchers tracked H₂O molecules as they transitioned from a frozen state to room temperature. The water first morphed into a dense liquid, then, almost instantly, shifted into a lower‑density liquid phase.

The outcome was startling: at ambient conditions, water does not settle into a single, stable density. Instead, it fluctuates between high‑ and low‑density states, effectively behaving as two distinct liquids simultaneously.

This discovery underscores water’s complexity, revealing that even at everyday temperatures, its molecular arrangement remains in a dynamic dance between two density regimes.

3 A Quantum Double Liquid

In 2018, scientists unveiled a startling quantum secret: water exists as two distinct liquids at the subatomic level. Though the two forms—ortho‑water and para‑water—appear identical to the naked eye, their internal spin orientations differ.

Each water molecule consists of two hydrogen atoms bound to an oxygen atom. When the spins of the hydrogen nuclei align in the same direction, the molecule is classified as ortho‑water. Conversely, if the spins point opposite each other, the molecule becomes para‑water.In a groundbreaking experiment, researchers applied a strong electric field to separate the two spin isomers, then introduced supercooled diazenylium molecules. Remarkably, para‑water reacted about 25 percent faster, forming H₃O⁺ (hydronium) more quickly than ortho‑water, confirming that the two liquids behave differently at the chemical level.

This quantum double nature adds another layer to water’s already enigmatic profile, showing that even a simple molecule harbors hidden complexity.

2 Oldest Water In The Universe

In 2011, astronomers uncovered the universe’s most ancient reservoir of water—a colossal cloud of vapor located 12 billion light‑years away, dating back 12 billion years. This gargantuan mass of H₂O dwarfs Earth’s oceans, containing enough water that, if our seas were multiplied by 140 trillion, they would still fall short.

The Milky Way, by comparison, holds roughly 4,000 times less water vapor than this intergalactic behemoth. Beyond sheer size, the cloud’s age provides compelling evidence that water has existed for nearly the entire lifespan of the cosmos.

Encircling a supermassive quasar—APM 08279+5255—the cloud resides near a black hole capable of devouring 20 billion Suns and radiating energy equivalent to a quadrillion suns. The surrounding gas reservoir is so massive that it could, in theory, feed the black hole to grow six times larger than its current mass.

This discovery not only pushes the boundary of how early water formed in the universe but also illustrates the intimate link between water vapor and the most energetic objects known.

1 Water’s Behavior Solved

No other liquid rivals water’s strangeness. While most substances become denser upon solidifying, water does the opposite—its solid form is lighter, allowing icebergs to float and lakes to retain liquid cores even in freezing conditions. Water also boasts unusually high surface tension, a lofty boiling point, and the capacity to dissolve more chemicals than most liquids.

In 2018, researchers pinpointed the structural secret behind water’s quirks. They discovered that water molecules preferentially arrange themselves into tetrahedral pyramids, each comprised of five molecules. These pyramidal clusters can link together, forming larger, ordered structures.

Interlaced amid a chaotic sea of other molecules, these orderly pyramids grant water its unique blend of pattern and disorder, underpinning its anomalous density, surface tension, and thermal properties. When scientists artificially disrupted the pyramidal arrangement, ice sank, and many of water’s hallmark characteristics vanished—demonstrating that life itself hinges on these molecular quirks.

In short, the delicate balance between structured pyramids and surrounding chaos makes water the indispensable, life‑supporting liquid we rely on.

Warning: This list is not for the faint of heart. There are invisible monsters living in your tap water, creatures that swim and multiply by the billions inside every drop of brisk, refreshing water you slurp down your gullet, tiny demons that…well, okay, they’re actually not all that bad. All water has bacteria and protozoans to some extent, most of them completely harmless. But once you see what they look like up close and personal, you might never get the image out of your head. Here are the 10 microorganisms you could be drinking right now.

10 Microorganisms You Might Encounter In Your Glass

10 Cryptosporidium

When municipal water systems pump water to homes, they run it through a series of filtration and disinfection steps. The goal is to strip away the bacteria that naturally inhabit lakes and rivers. Even the most sophisticated filtration can’t catch everything, and that’s where cryptosporidium slips through. Cryptosporidium is a protozoan—a single‑celled organism—that’s notorious for causing crippling diarrhea, a condition called cryptosporidiosis.

The parasite latches onto the intestinal lining and releases oocysts into the feces, which then re‑contaminate water sources if that waste isn’t properly treated. Modern treatment plants can remove about 99 % of these oocysts, but the remaining fraction can still make its way into your tap. In 1998, a bloom of cryptosporidium in Sydney, Australia, rose to “acceptable health limits” before officials took action, illustrating that even low‑level exposure is deemed tolerable despite the risk of illness.

9 Anabaena Circinalis

Anabaena circinalis is a cyanobacterium that thrives in freshwater reservoirs across the globe—from Australia to North America. These ancient, multicellular organisms are capable of producing potent neurotoxins such as anatoxin‑a and saxitoxin. An outbreak in the 1950s introduced anatoxin‑a into a drinking‑water supply, leading to mass cattle deaths in the United States.

In Australian reservoirs, certain strains of Anabaena have been linked to the production of saxitoxin, a toxin that can cause respiratory arrest and death. The military even classifies saxitoxin as a Schedule 1 substance because of its potential for weaponization. Fortunately, cyanobacteria are relatively easy to filter out—at least for now—so routine water‑treatment processes keep them at bay.

8 Rotifers

Rotifers are microscopic (though some grow up to 1 mm, visible to the naked eye) animals that inhabit virtually every freshwater environment. They’re among the most common contaminants found in municipal water supplies, yet they pose no direct threat to human health.

Their presence is actually a red flag for water‑utilities: organisms this large shouldn’t survive modern filtration. When rotifers appear, they often act as carriers for other microbes—protozoa like cryptosporidium and various bacteria—making them useful bio‑indicators of filtration failures. In short, spotting a rotifer means something’s amiss in the treatment train.

7 Copepods

Copepods are tiny crustaceans—essentially miniature shrimp—that can reach up to 2 mm in length. In 2009, residents of Connecticut reported thousands of these “tiny polliwogs” swirling in their tap water, sparking horror and disgust.

While they’re not harmful to humans and even help clean water by feeding on toxins, their ability to bypass filtration systems signals that smaller, potentially dangerous microbes could also be slipping through. Their sudden appearance is a reminder that even the most robust treatment processes can have blind spots.

6 Escherichia Coli

E. coli is a bacteria that lives in and around fecal matter. It’s one of the most well‑known pathogens, linked to food‑borne outbreaks and water‑borne illnesses. The EPA permits E. coli to appear in up to 5 % of monthly water samples; any more and the water fails safety standards.

Because water testing involves taking dozens of samples each month, it’s statistically inevitable that low‑level traces of E. coli will be detected in a small fraction of those tests. Nevertheless, the presence of this bacterium serves as an important indicator of overall water quality and the effectiveness of treatment processes.

5 Rhizopus Stolonifer (Bread Mold)

Rhizopus stolonifer, commonly known as black bread mold, is a ubiquitous fungus that colonizes stale bread and other organic matter. Its spores can become airborne and settle into tap water, where they’re occasionally detected.

A 2006 study found Rhizopus spores in 2.9 % of water samples—a relatively low occurrence compared with bacterial contaminants. While the mold can produce mycotoxins harmful at high concentrations, the levels typically found in drinking water are far below those that cause health issues.

4 Naegleria Fowleri

Naegleria fowleri is an amoeba that loves warm freshwater and, unfortunately, the human brain. It enters the body through the nasal passages, travels up the olfactory nerve, and causes primary amoebic meningoencephalitis (PAM), a disease with a 98 % fatality rate.

Although infection via drinking water is rare—most cases stem from swimming or diving in warm lakes—there have been documented incidents where the amoeba was found in household plumbing, including bathtub faucets and showerheads. In 2011, two Louisiana residents died after a nasal rinse made with contaminated tap water, underscoring the importance of using sterile water for any nasal irrigation.

3 Legionella Pneumophila

Legionella pneumophila earned its ominous reputation after an outbreak at an American Legion convention in 1976, which caused 34 deaths and over 200 illnesses. The bacterium thrives in warm water systems and can cause Legionnaires’ disease, a severe form of pneumonia that sends roughly 18,000 people to hospitals each year in the United States.

Symptoms range from high fever and muscle aches to confusion and vomiting. While the U.S. military once explored weaponizing Legionella, ordinary citizens are more likely to encounter it in contaminated hot‑water systems, cooling towers, or poorly maintained plumbing.

2 Chaetomium Species

Chaetomium is a genus of mold that prefers damp environments such as bathrooms, basements, and, occasionally, tap water. When present, it can impart an off‑taste or odor to the water, prompting consumers to stop drinking it.

Although Chaetomium spores are not highly pathogenic, they can cause a rare infection called phaeohyphomycosis in immunocompromised individuals and may trigger allergic reactions in sensitive people after chronic exposure.

1 Salmonella

Salmonella is a notorious bacterial culprit behind food‑borne illnesses, especially in raw poultry and eggs. Less frequently, it contaminates drinking water, leading to outbreaks of fever, vomiting, and diarrhea.

In 2008, Colorado’s municipal water supply was linked to 79 cases of salmonella poisoning, while a study in Togo, Africa, identified 26 cases tied to contaminated tap water. Vulnerable populations—such as the elderly and those with weakened immune systems—are especially at risk. As Benjamin Franklin quipped, “In wine there is wisdom, in beer there is freedom, in water there is bacteria.”

Stay vigilant, keep your water filters maintained, and consider periodic testing if you rely on private wells. Knowledge is the best defense against these microscopic guests.

The human body is made up of roughly 55% to 78% water, depending on your size and age. While we need between one and seven liters each day to stay hydrated, the very substance that keeps us alive can also be the cause of a fatal mishap. In this article we dive into the ten ways water can kill you, illustrating how a seemingly harmless liquid can turn deadly under the right (or wrong) circumstances.

1 Hypothermia

Hypothermia occurs when your core temperature drops below the level needed for normal metabolism—below 35 °C (95 °F) for humans. If you’re immersed in cold water and your body can’t generate enough heat to replace what’s being lost, your core temperature plummets. Symptoms start with shivering and mental confusion, then progress to severe impairment. Water conducts heat away from the body roughly 25 times faster than air, so even water that feels “cool” can be lethal. A water temperature of just 10 °C (50 °F) can claim a life within an hour, while near‑freezing water (around 2 °C/28 °F) can cause death in as little as 15 minutes. The Titanic disaster is a stark illustration: most passengers who entered the icy Atlantic succumbed within half an hour.

2 Scalding

Scalding is a burn caused by contact with heated liquids. Most scalds are first‑ or second‑degree, but prolonged exposure to boiling water can produce third‑ or fourth‑degree burns, destroying skin, fat, and even muscle. Historically, boiling water was used as an execution method in parts of Europe and Asia: victims were either dropped into a pre‑heated cauldron or immersed before the water reached boiling point. The result was severe immersion burns across the arms, torso, and legs, with the epidermis and dermis vaporized, sub‑cutaneous fat liquefied, and major vessels exposed. Even today, unsuspecting swimmers can suffer fatal scalds by misjudging the temperature of natural hot springs.

3 Avalanche

Ice is frozen water, and when massive amounts of snow cascade down a slope, the result is an avalanche. Triggered when the stress on a snowpack exceeds its strength, avalanches can accelerate rapidly, entraining more snow and increasing in volume. A staggering 85.7% of avalanche fatalities are due to asphyxiation. Survivors who manage to carve a pocket of air find that their breath quickly refreezes, forming an “ice mask” that can suffocate them within thirty minutes. Less than half of those fully buried survive; nobody buried deeper than seven feet has ever lived to tell the tale. During World War I, between 40,000 and 80,000 soldiers perished in avalanches on the Alpine front.

4 Waterborne Diseases

Waterborne diseases arise from pathogenic microorganisms in contaminated fresh water. Human sewage is the most common source of raw‑water contamination worldwide. Infection can occur during bathing, washing, drinking, or food preparation. Diarrheal diseases dominate, especially among children in developing nations, accounting for roughly 1.8 million deaths each year. Water quality is judged by microbiological parameters—such as coliform bacteria, E. coli, viruses, and protozoan parasites—and chemical parameters, like heavy‑metal buildup. For instance, an estimated 60 million people have suffered fluoride poisoning from poorly regulated well water.

5 Holding Your Pee…Sort Of

While water intake inevitably leads to urination, the myth that you can die by “holding it in” is largely unfounded. You cannot rupture your bladder from sheer pressure; the urethral sphincters and the kidneys prevent such a buildup. The worst that can happen is a urinary‑tract infection, which, if left untreated, could become serious. In extreme cases where an obstruction occurs, the kidneys fail first, prompting the body to forcefully release the bladder’s contents. Historical legend claims astronomer Tycho Brahe died from refusing to leave a banquet table to urinate, but modern research points to a kidney stone and subsequent renal failure as the true cause.

6 Dangerous Driving Conditions

Driving in rain can be perilous for several reasons. First, the initial rainfall washes away accumulated oil and lubricants on the road surface, creating an oily slick that reduces tire traction. Prolonged rain can form deep puddles, leading to hydroplaning where tires lose contact with the road entirely. Poor drainage creates standing water that can cause vehicles to spin out of control. Additionally, heavy rain reduces visibility, making it harder to spot hazards, pedestrians, or other motorists. In the United States alone, over 3,000 fatalities each year are linked to rain‑related auto accidents.

7 Electric Shock

Pure water is a poor conductor, but once dissolved salts and minerals are present, it becomes an excellent pathway for electricity. Sodium (Na⁺) and chloride (Cl⁻) ions separate and allow current to flow. This property makes water a dangerous medium when electrical sources are nearby. A strong current can cause muscles to contract, preventing the victim from letting go, and can trigger ventricular fibrillation, tissue damage, or death. In 2012, two boys were electrocuted while swimming in a lake after a nearby boathouse’s frayed wiring entered the water, also shocking five adults who attempted a rescue.

8 Chinese Water Torture

Chinese water torture involves a steady drip of water onto a restrained person’s forehead. Invented in the 15th century by Hippolytus de Marsiliis, the method exploits the psychological impact of each drop. Though the name suggests an exotic origin, the technique was likely coined to add an ominous flair. Victims, unable to move, watch each droplet land, and over prolonged periods the cumulative effect can induce extreme mental distress, sometimes described as “driven frantic.” Historical accounts from the Spanish Inquisition detail this practice, noting the forehead’s sensitivity as the optimal spot for the torment.

9 Tsunami

A tsunami is a series of massive water waves generated by a sudden displacement of a large water body—typically an ocean or lake. Triggers include earthquakes, volcanic eruptions, landslides, glacier calvings, and even meteorite impacts. While everyday wind‑generated waves have wavelengths around 100 m and heights of about 2 m, a tsunami in the deep ocean can stretch over 200 km in wavelength and travel faster than 800 km/h (500 mph). The destructive power comes from the wall of water slamming into shorelines and the subsequent massive volume of water retreating, dragging debris inland. The 2004 Indian Ocean tsunami claimed over 230,000 lives across 14 nations, underscoring the catastrophic potential of this water‑borne phenomenon.

10 Water Intoxication

Water intoxication, also known as dilutional hyponatremia, occurs when excessive fluid consumption dilutes the body’s electrolytes, especially sodium, leading to brain swelling and potentially fatal outcomes. Though rare in everyday life, most deaths stem from extreme drinking contests or intense exercise where participants consume large volumes without replenishing electrolytes. The practice of “water cure”—forcing a victim to ingest massive amounts of water—can also trigger this condition. In 2003, a SUNY Plattsburgh freshman died after fraternity hazing forced him to drink gallons of water through a funnel, causing his brain to swell and leading to his untimely death.

Water is essential, but as we’ve seen, it can also be a silent killer. Respect its power, stay informed, and keep yourself safe.

Bizarre and sometimes dangerous marine worms represent genuine monstrosities in animal form. These creatures can display the worst possible combination of being slimy and “toothy”. Prepare for a science‑fiction‑turned‑reality journey into the weird and wild world of water worms that slither and chomp their way through ocean life. 10 wicked worrisome creatures await your curiosity.

10 Wicked Worrisome Highlights

10 The Bootlace Worm

Too long to believe

Just how long can a worm get? Maybe try asking a Bootlace Worm next time you tie your laces at the beach. Reaching a crazy length of up to 180 feet, the Bootlace worm Lineus longissimus is not merely the longest worm on the planet. It is the world’s longest animal, period. Being the longest is not enough horror for this record‑breaker. The worm outdoes itself by being superbly poisonous to boot. The worm creates a potent toxin that is contained within the slimy mucous secreted by the worm. This hazardous chemical soup was found to be a peptide‑based compound in the course of investigation by Professor Ulf Göransson and colleagues at Uppsala University in Sweden. The primary toxin in the mucus could immobilize invertebrates such as crustaceans and insects. Interestingly, deadly peptides are found in cone shells from the tropics, but the discovery of bootlace worm toxicity represents a cold‑water example. The bootlace worm thrives in chilly waters off European coasts. As a poisonous rather than venomous animal, the bootlace worm is an interesting case given the worm’s use of poisonous mucus to hunt. Typically, a poisonous animal uses a toxin as a defense against being eaten, whereas a hunter would inject venom.

9 Osedax Worms

Oceanic Undertakers

Ocean‑going killers of cetaceans such as large sharks and Orcas might have some little accomplices in the form of worms that take care of the evidence. What happens to whale bones when they sink to the bottom of the sea? Why might it be hard to find many whale skeletons? They get eaten. Little marine worms called Osedax crave bone minerals and actually feed on the bones of whales. Nature lets nearly nothing go to waste and bone‑eating seems to be working well for these creatures.

The so‑called “Zombie worms” are a fairly new discovery, first observed in 2002 in the wild thanks to advances in deep‑sea exploration before being scientifically described in the lab in 2004. The worms were discovered at a depth of 10,000 feet feeding in a grey whale skeleton. Crazier yet, these creatures lack a stomach or a mouth. Osadex worms just secrete acid that melts bone, releasing meat‑like nutrients for the worms to take up through the work of symbiotic bacteria that proceed to break down the actual nutrients. Only females do the acid drilling, while males live inside the females as microscopic organisms. Would the worms eat a dead human? Pretty likely, since they have fed on cow bones at sea…

8 Piling Worm

Mating En Masse

When the lunar signals are right, huge marine worms common in the Pacific Northwest called Giant piling worms, grow up to a foot‑long swarm to the surface and mate. The majority of the time, the creatures stay hidden in the sand, collecting food with their pincer‑like jaws. Imagine swimming at night and being surrounded by foot‑long marine worms. No thanks.

The marine pile worm species was identified as Nereis brandti, a type of polychaete worm, according to Louise Page, a biologist from the University of Victoria in BC, Canada. Page listed sand‑dwelling habits as the typical behavior of the worms outside of mating season. The enormous size of the worms is off‑putting to would‑be adventurers, and reinforced by the presence of jaws which could deliver a painful bite thanks to the sharp appendages around the mouth. The swarming behavior gives rise to the fertilization of eggs and the appearance of tiny larval worms. Upon maturation, the worms may seem scary, but are actually most focused on eating algae. Their jaws are usually used to defend territory but offer only limited protection when the worms swim through the water, vulnerable to countless larger hunters.

7 Antarctic Scale Worm

Horror at the South Pole

Covered in bristles with dentacle jaws that look like something from the movie “Tremors”, the stubby, horrific‑looking Antarctic scale worm Eulagisca gigantea could certainly deliver a nasty bite. Growing nearly eight inches long, the marine worm’s scaly body acts as camouflage against the sea bed. But then it can rise up and attack prey with its proboscis which looks like a head with massive teeth. The hunter’s jaws efficiently rip into prey, serving as a powerful hunting tool that is a true concealed weapon. uses its jaws to rip into a variety of prey items, but if that is not enough, they are a true concealed weapon.

The worm can simply invert the appendage and pull it back into the body. Anytime there is an opportunity, outshoot the jaws. While the dentitions are not true teeth, being in an invertebrate, they are a pretty high‑quality likeness of a wolf’s fangs, albeit attached to a marine worm’s body. The creature is then partially beautiful in addition to being partially horrible‑looking. It is covered in bristly hairs that have a shiny golden appearance, offering an incongruous contrast to the worm’s monstrous capabilities. Prey items are simply ripped up by the sci‑fi‑worthy creature that has no problem remaining active in icy waters. With its fitting Latin binomial gigantea, the hefty creature can descend to depths of over 1,600 feet.

6 Fat Innkeeper Worm

The Ugly Guest Host

Known in common language as the Fat Innkeeper Worm, Urechis unicinctus is an awful‑looking creature, often compared to a penis in appearance. Yet its activities provide valuable habitat for a wide range of marine life that take refuge in the burrows they create. The bizarre worm is huge, bulbous, and beige and is named due to both its looks and the habit of creating horseshoe‑shaped burrows that serve as invaluable “inns” for a vast range of intertidal creatures. Gobies, other worm varieties, and even small crabs use the burrows, without harming or helping the fat innkeeper worm itself. The creature is a denizen of estuarine, brackish waters, and mudflats, hanging out around coastal wetlands that are unfortunately extremely vulnerable to climate change and development‑based disruptions.

The fat innkeeper worm feeds on plankton and is well known from the coast of California. Belonging to the phylum Echiura, the creatures may reach seven inches in length, large enough to startle beachgoers should be encounter one for the first time. In addition to maintaining “inns” for small creatures, the worms themselves are a veritable buffet course for larger visitors to wetlands, including bat rays, which suck up the worms, and opportunistic otters.

5 Multi‑Butt Worm

Ifs, Butts & Maybes

No ifs or maybes, but plenty of but(t)s? Yes indeed. There is a marine worm with one head and well over 100 derrieres, according to recent findings. The annelid worm species Ramisyllis multicaudata is distantly related to the familiar earthworm but inhabits oceans instead of gardens and lives in sea sponges that serve as hosts. Research published in the Journal of Morphology describes how the worms use the hollowed‑out interiors of marine sponges, an even simpler life form as a place of residence. How the worms feed is a matter of further research interest, given the lack of digested food found in the digestive tracts of the marine worms upon examination.

What is well documented is the importance of the many butts of the worms in reproduction, but not in the way you might expect. Each worm butt actually breaks away eventually and develops eyes and a brain before developing into a brand new worm that starts the life cycle over again. In extreme cases, the number of rears on a Ramisyllis multicaudata worm could be far more than reasonable imaginable. Up to 1,000 rear ends may be part of one worm.

4 The Burning Worm

Fire Under the Sea

Danger often comes in small bundles and that is the case with certain marine worms. While they only grow up to be about three to four inches in length, the worm community’s answer to the lionfish, scorpion, and stinging nettle is nothing to mess with. Found in warm tropical waters, Bearded fireworms Hermodice carunculata are covered in horrifying bristles that unload venom onto anyone or anything unlucky enough to touch them. Ouch! These toxic sea creatures are associated with Western and limited central Atlantic habitats that include coral reefs, under rocks, and even nestled in flotsam and jetsam drifting along the waves at sea.

The awful bristles are shiny and beautiful, having a resplendent appearance similar to a lionfish or sea anemone.  The worm’s hollowed‑out bristles effortlessly slide into the flesh of any creature that comes into contact with them and snap away, leaving bristles embedded. This causes mechanical and chemical irritation akin to being stung by a bee. To be fair, the worms do give out a warning first if bothered by first flaring out their bristles. Clearly, one of the laws of the sea to remember at all times is when in doubt, do not touch!

3 Parchment Worm

The Animal, The Machine

Looking like a literal paper dragon, the parchment worm Chaetopterus variopedatus constructs its burrow out of an extension of its body. While fragile, it is a strange mix of graceful and absolutely grotesque. The creature is gentle and feeds on plankton that it traps, and is not an aggressive hunter like many of the tougher worms in this account. Growing to about 10 inches in length, the worm is a bizarre but successful animal as a globally distributed generalist found in both tropical and cooler waters.

The feeding strategy of the parchment worm is decidedly odd. The worm’s body is formed by three sections, which include mouth and bristly body segments. Next, there is a structure that forms mucous and secreted mud‑based bags in the center, with segments that pump water into the body tube. Finally, a third section made up of many segments in a row concludes the body plan. The remarkably mechanical animals simply bag up food filtered from the water in mucous and mud “capsules” and swallow them like pellets for digestion.

2 Spaghetti Worm

A Rebel Among Worms

If you dumped a bowl of noodles on the seafloor, you would have a crazy‑looking creature that looks exactly like either spaghetti come to life, or even a crawling mop head. All you see are the tentacle‑like extensions as the worm winds along the seabed in search of meals. Unlike many marine worms, the spaghetti worm spends its life in the open, not needing the protection of a burrow. The creature is still in the process of being given a species name.

The discovery of the creature is fairly new, with the first sighting and description taking place during a research trip in the Gulf of California by the Monterey Bay Aquarium Research Institute (MBARI). This “dancing mop” may look vulnerable but apparently, the array of appendages allows the worm to collect small food items, all without having any eyes! The worm is a type of polychaete marine worm and belongs to the genus Biremis. Given the importance of polychaete worms in the marine environment, there is a World Polychaete Day which is July 1st to celebrate their existence. Footage of the mysterious Biremis species was first released on July 1st, 2012, nine years after MBARI researchers discovered it, marking the special day.

1 The Bobbit Worm

Worse Than Science Fiction

What creature bursts from the sea floor and grabs or even saws or scissors its prey right in half? The horrific Bobbit Worm Eunice aphroditois, armed with massive fangs that have a convergent resemblance to teeth can slice fish in half, right through the spine, and deliver a nasty bite if provoked. Stinging bristles just add to the nightmare. The worm is also dangerous to humans and should be viewed with great respect, not just curiosity. Drably colored segments of the worm are accented with iridescent highlights that add a dash of beauty to unimaginable ugliness.

The worm is akin to a viper, equipped with massive fang‑like pincers that are attached to the head. The force generated by the bite combines with the shocking striking speed to make encountering this animal a little bit like brushing into an underwater mine. In addition to the risks posed by a bite, the toxic bristles are capable of causing long‑term nerve damage if the animal is handled unwittingly. Disturbingly, this animal can on occasion reach 10 feet in length and weigh around one pound in the most extreme cases. That said, it is certainly possible larger and more vicious specimens are waiting to be discovered.

When you think about water scarcity, the phrase 10 staggering wastes of water should instantly spring to mind. From massive farms gulping more than entire cities to everyday habits that squander gallons, the numbers are eye‑opening and the stories are surprisingly bizarre. Let’s dive into the ten most jaw‑dropping ways water is being wasted every single day.

10 One Farming Family Uses More Water Than All Of Las Vegas

Farming inevitably demands water, but the scale at which some operations draw it can be mind‑boggling. The Abbati family, owners of a sprawling agricultural empire, were found to consume more water in a single year than the entire Las Vegas Valley. Their 2023 water usage totaled an astronomical 260,000 acre‑feet. To put that into perspective, one acre‑foot equals 326,000 gallons, meaning the Abbatis’ consumption topped 84.7 billion gallons. By contrast, Las Vegas used roughly 200,000 acre‑feet, or about 65 billion gallons.

The bulk of this water comes from the Imperial Irrigation District, where a handful of twenty families command more water than three hundred smaller farms combined, amassing about 387 billion gallons in 2022 alone. This district holds the largest Colorado River claim, and roughly one‑seventh of every drop is routed to these large‑scale growers, many of whom focus on hay for livestock rather than food crops for humans.

Critics point out that the hay is often exported, effectively selling water abroad for a paltry $20 per acre‑foot. The water rights these families enjoy were cemented nearly a century ago, and the descendants of those original claimants still reap the benefits—even as reservoirs shrink to historic lows.

Why This Is One Of The 10 Staggering Wastes Of Water

The Abbati family’s consumption illustrates how historic water‑right allocations can create modern‑day water gluttony, turning a vital resource into an almost limitless commodity for a privileged few.

9 It Takes 3 Gallons Of Water To Produce A Single Almond

Almonds may be a tasty snack, but each nut carries a hefty water bill. Growing a single almond requires over three gallons of water. A pound of almonds—roughly 400 nuts—means each nut is responsible for about 0.0075 gallons. An average almond tree produces between 50 and 65 pounds of nuts, translating to around 20,000 almonds per tree. That equates to roughly 60,000 gallons of water per tree.

If an orchard yields 4,500 pounds of almonds, the water demand climbs to 5.4 million gallons. Across California’s 7,600 almond farms, the total water usage balloons to an astonishing 41.04 billion gallons. About 70 percent of California’s almond harvest is exported, meaning a massive portion of that water is effectively shipped overseas.

To put it in city‑scale terms, the water needed for all exported California almonds could supply Los Angeles residents for three years. Almonds account for 10 percent of all water used in California—more than the combined consumption of Los Angeles and San Francisco. And while almonds dominate the headlines, corn also drinks heavily, with each pound requiring roughly 110 gallons of water, contributing to the nation’s 346 million‑ton corn production in 2022‑2023.

8 Golf Courses Use Billions Of Gallons Per Day

Golf lovers may admire immaculate greens, but the water behind those perfect fairways is staggering. Across the United States, more than 16,000 golf courses—over half the world’s total—consume roughly two billion gallons of water each day. The average course drinks about 312,000 gallons daily, while desert courses in places like Palm Springs can gulp up to a million gallons in a single day.

These figures illustrate a massive, often under‑appreciated, demand on freshwater resources, especially in arid regions where water is already scarce. The sheer scale of irrigation required to keep those pristine courses playable makes golf a surprisingly thirsty pastime.

7 Reverse Osmosis Systems Can Waste Gallons Of Water For Every One They Clean

Reverse osmosis (RO) units promise crystal‑clear drinking water by pushing water through a semi‑permeable membrane that filters out contaminants. While the technology works effectively, many units are notoriously wasteful. Even top‑performing systems can discard up to five gallons of water for every gallon of purified water they produce. Some studies suggest certain models waste as much as twenty gallons of raw water for each gallon of clean water.

Newer “1:1” RO systems claim to match clean water output with input, but they are less common and typically carry a higher price tag. The waste factor highlights a paradox: in the quest for pure water, we may be squandering even more of the very resource we’re trying to conserve.

6 Up To 37 Gallons Go Into Making A Single Roll Of Toilet Paper

Toilet paper may seem innocuous, but its production is a water‑intensive process. In the United States alone, manufacturing this humble product consumes an estimated 473.6 billion gallons of water annually—averaging about 37 gallons per roll. This massive demand stems from the pulping of roughly 15 million trees each year.

While some argue that bidets could reduce toilet paper usage, a single bidet flush uses about one‑eighth of a gallon. It would take roughly 296 bidet sprays to equal the water spent on a single roll of toilet paper. Moreover, each flush of used toilet paper adds about 1.6 gallons of water in a low‑flow toilet, meaning the total water footprint of a roll—including its disposal—can exceed 400 gallons.

This comparison underscores how everyday choices, even seemingly trivial ones, can add up to staggering water consumption.

5 It Takes 17 Million Barrels Of Oil To Make Bottled Water Bottles

Bottled water is often marketed as a premium, pure alternative to tap water, yet its production carries a hefty environmental price tag. Roughly 25 percent of bottled water sold in the United States is simply filtered municipal water, yet consumers still purchase it in massive volumes—about 16 billion gallons in 2022.

Creating the plastic bottles for that water requires an estimated 17 million barrels of oil each year, a figure originally reported in 2006 and likely higher today due to increased consumption. Beyond the oil cost, the process consumes additional water and energy, making bottled water one of the most wasteful beverage choices on the market.

4 Chocolate Requires More Water Than Nearly Any Other Crop

Chocolate lovers may not realize that their sweet indulgence comes with a massive water footprint. Producing one kilogram of cocoa beans—used to make chocolate—requires about 17,196 liters of water, equivalent to roughly 4,542 gallons. This translates to over 2,000 gallons per pound of chocolate.

For context, raising a cow to market weight also consumes about 1,910 gallons of water per pound of beef. Thus, a single Hershey‑style chocolate bar can demand as much as 528 gallons (2,000 liters) of water, putting it in the same league as beef in terms of water intensity.

This hidden water cost highlights how even beloved treats can be surprisingly thirsty, especially when sourced from regions already facing water stress.

3 Hand Washing Dishes Wastes More Than 5 Times The Water Of A Dishwasher

When it comes to cleaning up after a meal, most people choose between hand‑washing in a sink or loading a dishwasher. While a modern, energy‑efficient dishwasher can operate on as little as three to four gallons per cycle, hand‑washing can consume anywhere from 20 to 27 gallons, depending on technique and flow rate.

In practical terms, a dishwasher uses roughly one‑fifth of the water a typical hand‑wash does. Over a year, an efficient dishwasher can save up to 5,000 gallons of water compared to habitual hand‑washing. The key is to run the dishwasher only when fully loaded and to select eco‑friendly settings.

This comparison demonstrates that a simple habit change in the kitchen can lead to substantial water savings.

2 Starbucks Used To Waste 6 Million Gallons A Day For No Reason

Back in 2008, a startling discovery revealed that Starbucks locations across the United Kingdom were letting a “dipper well”—a continuously running sink used to rinse utensils—flow nonstop. This practice wasted an estimated six million gallons of water each day.

Management argued that a perpetually running sink prevented bacterial growth, but experts quickly debunked the claim, pointing out that a constantly flowing faucet does not improve sanitation. Moreover, many Starbucks employees were unaware of the sink’s purpose, yet were still required to keep it running as company policy.

The waste was purely procedural, highlighting how corporate habits can unintentionally squander massive amounts of water without any tangible benefit.

1 Cruise Ships Dump 150,000 Gallons Of Sewage Into The Ocean Daily

Cruise ships may promise luxury on the high seas, but they also generate a staggering waste stream. A typical 3,000‑passenger vessel can discharge about 150,000 gallons of sewage each week, with some ships releasing up to 74,000 gallons in a single day.

While many nations ban waste dumping within coastal waters, cruise ships often wait until they reach international waters before flushing. In addition to raw sewage, they also release gray water from showers and laundry, as well as oily bilge water, all of which end up in the ocean.

This practice underscores the hidden environmental cost of maritime tourism, where the allure of vacationing on a floating resort comes with a massive, often invisible, water pollution footprint.

These ten eye‑opening examples illustrate just how diverse and pervasive water waste can be—from large‑scale agriculture to everyday habits. By recognizing the scale of each waste, we can start making smarter choices and push for policies that protect this precious resource.

Summer brings endless sunshine, splashing fun, and family get‑aways. Across the globe, travelers flock to water parks to soak up all three, hoping to stay safe while they play. Whether you’re sliding down a modest kiddie chute or tackling a jaw‑dropping extreme waterslide, these wet wonders deliver nonstop excitement. According to the International Association of Amusement Parks and Attractions (IAAPA), U.S. parks alone generate more than $50 billion each year and employ roughly 2.3 million people.^[1] This article rounds up the top 10 record‑breaking attractions that keep the world talking.

Why These Top 10 Record Attractions Wow

10 World’s Tallest Waterslide

Standing an astonishing 51.4 meters (168.6 ft) tall, the Guinness‑approved Verruckt slide—German for “crazy” or “insane”—reigns as the world’s tallest waterslide. Nestled at Schlitterbahn in Kansas City, Kansas, the ride was announced in late 2012, delayed by construction hiccups, and finally opened to the public at the end of July 2014. Co‑owner Jeff Henry engineered it for three riders per run, catapulting them 17 stories downward at speeds that can hit 100 km/h (60 mph). Its height eclipses both Niagara Falls and the Statue of Liberty (excluding the pedestal), and a staircase of hundreds of steps leads brave souls to the launch platform.

Tragically, in August 2016, Caleb Schwab, son of Kansas state Rep. Scott Schwab, suffered a fatal neck injury while riding Verruckt and died on site. The incident shocked the community and spurred plans to demolish the slide. The Associated Press noted Kansas’s reputation for lax amusement‑park regulation, suggesting the ride may have been pushed beyond safe limits.

9 World’s Longest Waterslide

Action Park in Vernon, New Jersey, boasts the world’s longest waterslide, stretching 602 meters (1,975 ft)—over one‑third of a mile. The unnamed slide comprises 20 sections, each 30 meters (100 ft) long, constructed from polyvinyl chloride—the same material used for children’s bounce houses—making the slide inflatable. Filling the slide takes more than two hours, it pumps roughly 3,800 liters (1,000 gal) of water per hour, and rides can last up to 90 seconds.

Certified by Guinness World Records in 2015, the slide never opened to the public. Lacking a weight limit, its danger potential remained uncertain, and a lengthy state‑certification process delayed any broader use. Only a handful of employees were ever permitted to test the record‑setting ride.

8 World’s Longest Water Coaster

Mammoth, located at Holiday World & Splashin’ Safari in Santa Claus, Indiana, blends traditional slides with a conveyor‑belt lift, delivering a water‑coaster experience that feels like a roller‑coaster while soaking riders. Opened in May 2012, Mammoth dethroned its predecessor Wildebeest and now stretches 537 meters (1,763 ft) of twists, turns, and ascents.

The coaster accommodates six‑person rafts that face inward, letting families share the thrill together. Riders enjoy six drops along the track, soaring over the expansive Holiday World landscape—a perfect pick for adrenaline junkies seeking both speed and splash.

7 World’s Tallest Water Coaster

Schlitterbahn Galveston Island’s MASSIV water coaster earns its Guinness title as the tallest of its kind, soaring 24.9 meters (81.6 ft) into the Texas sky. Built to celebrate the park’s tenth anniversary, MASSIV features a series of uphill climbs punctuated by a triple‑drop finale.

Lead designer Emily Colombo explained that balancing g‑forces, ride dynamics, and velocities was essential for success. The coaster’s varying speeds and forces make it appealing to a wide audience, and park management emphasizes its versatility as a core attraction.

6 World’s Longest Lazy River

Providing a soothing counterpoint to high‑octane thrills, the lazy river at BSR Cable Park in Waco, Texas, stretches just shy of 1.6 kilometers (1 mile), securing the title of world’s longest. The river weaves through sun‑drenched sections and shaded retreats, catering to every rider’s preference.

While it may lack the novelty of more exotic attractions, its sheer length makes up for it. The river welcomes both adults and children, delivering a refreshing escape—especially during Texas’s scorching summer heat.

5 World’s Largest Outdoor Wave Pool

Venturing beyond the United States, Siam Park City in Bangkok’s Khan Na Yao district claims the world’s largest outdoor wave pool. Spanning an impressive 13,600 square meters (146,400 ft²), the pool generates waves up to 1.5 meters (5 ft) high, though safety controls cap them at 60 centimeters (24 in) to protect patrons.

Wave pools inevitably pose drowning risks, especially for children whose heads sit above the water’s surface amid turbulent conditions. Nevertheless, this massive pool offers a balanced experience between the leisurely flow of a lazy river and the adrenaline of a water coaster.

4 World’s Largest Indoor Wave Pool

Back in North America, West Edmonton Mall’s World Waterpark houses Blue Thunder, the globe’s biggest indoor wave pool. Featuring four active wave bays—each powered by a 1,500‑horsepower hydraulic system—Blue Thunder once operated eight bays before two were deactivated due to injury concerns from overly intense waves.

Today, the pool produces waves ranging from 1.5 to 1.8 meters (5–6 ft) using only the inner bays, holding a massive 12.3 million liters (3.2 million gal) of water. After hours, the pool transforms into a private venue for surfing, kayaking, paddleboarding, and more, with wave intensity adjusted to suit each activity.

3 World’s Longest Tube Waterslide

Germany’s Galaxy Erding water park showcases Magic‑Eye, the longest inner‑tube waterslide worldwide, measuring 356.3 meters (1,169 ft). Certified by Guinness World Records in November 2010, the slide opened in May 2007 and was constructed by Swiss firm Klarer Freizeitanlagen AG, a leader in slide engineering.

Magic‑Eye also rises 22 meters (72 ft) and features glowing interior lines that create a dazzling visual effect. However, the strobe‑like lighting may pose risks for riders with epilepsy, underscoring the importance of safety considerations.

2 The United States’ Largest Outdoor Water Park

Noah’s Ark Water Park in Wisconsin Dells claims the title of America’s largest outdoor water park, sprawling across 70 acres. While it doesn’t host any singular record‑setting rides, its 51 attractions collectively cement its status as the crown jewel of a town that proudly calls itself the “water‑park capital of the world.”

Thrill‑seekers can plunge down near‑vertical drops or ride a 400‑meter (1,300 ft) water coaster packed with unexpected twists. For a more relaxed experience, guests can drift along the lazy river or dip into the wave pool, which alternates wave activity every ten minutes. Occasionally, rides like the Scorpion—featuring a loop‑the‑loop—experience malfunctions, reminding visitors of the inherent risks in high‑speed water entertainment. Wisconsin’s seasonal climate also supports a host of indoor water parks, ensuring year‑round splash fun.

1 World’s Largest Indoor Water Park

Closing our countdown, Germany’s Tropical Islands Resort in Krausnick (southeast of Berlin) boasts the world’s biggest indoor water park, covering more than 16 acres and welcoming up to 6,000 guests simultaneously.

The resort delivers a climate‑controlled oasis topped with a glass roof, offering everything from kiddie paddling zones and modest slides to grand attractions and a Bali‑inspired lagoon. Visitors can bask in sunshine year‑round, regardless of external weather, making it a premier destination for families and adventure‑seekers alike.

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.

6 Edible Water Orbs That Can Replace Plastic Bottles And Are Entirely Biodegradable

Not long ago, bottled water was a novelty; today it’s a massive environmental menace, cluttering landfills worldwide. The plastic containers persist for centuries, prompting a push for reusable alternatives.

Enter Skipping Rocks Lab, the innovators behind “Ooho,” a flavorless, algae‑based sphere that holds water. After drinking, the orb can be eaten or biodegraded, offering a zero‑waste solution.

Made from sustainable algae, these orbs dissolve harmlessly if discarded, presenting a promising route to replace single‑use plastic bottles on a large scale.

With the right distribution networks, Ooho could dramatically cut the global plastic waste crisis while delivering a quirky, fun drinking experience.

5 The Anti‑Griddle Is Expensive, But It Allows For Incredible And Speedy Frozen Creations

The anti‑griddle, conceived by chef Grant Achatz and later commercialized with Philip Preston, flips traditional cooking on its head by flash‑freezing foods almost instantly.

Professional kitchens can afford the $1,500 price tag, but home cooks often find it out of reach. Nevertheless, the device’s ability to create dramatic textures—think frozen‑outside, melt‑inside desserts—makes it a coveted tool.

For DIY enthusiasts, Instructables offers a step‑by‑step guide to build a functional version for roughly $15, proving that a bit of ingenuity can bring high‑tech culinary tricks into any garage.

4 Cricket Flour Helps Ease People Into A Valuable New Food Source While Tasting Delicious

As the planet grapples with dwindling resources and a carbon‑intensive beef industry, scientists are turning to insects as a sustainable protein source. The “ick” factor is the biggest hurdle.

Enter cricket flour, a finely milled powder that masks the bug’s appearance while delivering a nutty, slightly earthy flavor. This flour powers everything from protein bars to chips, making the transition to entomophagy smoother for skeptics.

While still niche in Western markets, cricket flour presents a promising avenue to feed a growing global population without overtaxing the environment.

Its versatility in baked goods and snacks helps consumers dip their toes into bug‑based nutrition without confronting the visual disgust of whole insects.

3 Once Only For Snobby Chefs, Sous Vide Is Becoming Increasingly Mainstream

The sous‑vide method, which involves sealing food in a bag and immersing it in a precisely controlled water bath, has migrated from elite restaurant kitchens to everyday home cooking.

Professional chefs love it because it frees them to multitask while guaranteeing perfectly cooked results—no more guessing on doneness.

Critics once dismissed it as pretentious and costly, citing pricey immersion circulators and thermometers. However, culinary guru Martha Stewart shows that a basic thermometer, Ziploc bags, and a bit of know‑how can replicate the technique without breaking the bank.

Thus, sous‑vide is shedding its snob reputation and becoming a go‑to method for home cooks seeking restaurant‑quality meals.

2 The Trend To Eat Black Ice Cream Made With Activated Charcoal Is Dangerous For Some

Black ice cream, dyed with activated charcoal, surged in popularity as a counter‑trend to pastel “unicorn” desserts. First launched by Little Damage in Los Angeles, the gothic‑styled scoop quickly spread to specialty shops nationwide.

While the charcoal gives the treat a dramatic hue and a subtle earthy flavor, it also possesses potent adsorbing properties that can interfere with medications and supplements.

Consumers taking prescription drugs, vitamins, or birth‑control pills should exercise caution, as the charcoal may bind to these compounds, reducing their effectiveness.

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.

There are a handful of basics we instinctively cling to for survival: food, shelter and, most importantly, water. While humans can survive only a few days without a sip, the natural world hosts a surprising cast of critters that have learned to live almost entirely without drinking. Below you’ll meet 10 amazing animals that have turned the whole “need water” rule on its head.

10 Amazing Animals That Defy Dehydration

You’ve probably heard the cheeky phrase “drinks like a fish” used to describe a heavy‑drinking partygoer. On the surface it sounds logical – after all, fish live surrounded by water, so why wouldn’t they gulp it down constantly? The reality is far more nuanced. Freshwater fish actually never take a sip of water the way mammals or birds do.

Instead of drinking, these aquatic denizens absorb the liquid passively through their permeable skin and across the delicate membranes of their gills via osmosis. This subtle intake keeps them hydrated without the need for a mouthful of water.

The reason they can’t simply swallow water lies in the chemistry of their internal fluids. A freshwater fish’s blood is already less salty than the surrounding water. If it were to gulp the same freshwater, the sudden influx would upset the delicate salt balance, forcing the kidneys to work at an impossible speed. In extreme cases, the fish could literally burst from the pressure of the excess water.

To sidestep this peril, fish rely on their gills as sophisticated filters, allowing them to regulate ion concentrations and maintain homeostasis without ever having to “drink” in the conventional sense.

9 Mountain Gorillas Very Rarely Drink Water

Towering at up to 400 pounds, mountain gorillas are massive, yet their hydration strategy is remarkably minimalist. Their diet is a veritable salad bar of leaves, stems, occasional roots, flowers, fruit and a smattering of insects. The sheer water content of these succulent plants—often hovering around 50% moisture—provides a steady, reliable source of hydration.

In addition to the moisture locked inside their leafy meals, gorillas also harvest water from the morning dew that settles on vegetation. This tiny amount, when combined with their plant‑rich diet, usually suffices to keep them well‑hydrated.

Researchers have observed a subtle shift in recent years: as climate change nudges temperatures upward in the gorillas’ high‑altitude homes, the apes are drinking more often. Warmer conditions increase the risk of dehydration, prompting them to seek out actual water sources more frequently than in the past.

Nevertheless, under optimal, cooler conditions, a mountain gorilla can go an extended period without ever needing to dip its snout into a pool, relying instead on the moisture baked into its vegetal buffet.

8 Marine Mammals Get Most of Their Water From Their Prey

When you think of sea‑dwelling creatures, the image of a fish gulping seawater often pops up. Marine mammals, however, lack gills, so they’ve evolved a different approach to staying hydrated.

Cetaceans like whales and pinnipeds such as seals obtain the bulk of their water by metabolizing the protein and fat of the prey they consume. The biochemical breakdown of these nutrients releases water internally, effectively satisfying their hydration needs without a direct drink.

Even the tiniest of their meals—krill, which fuels the massive blue whale—contain enough moisture to keep the mammal’s water balance in check. In extreme situations where evaporation threatens to sap moisture, some marine mammals may supplement their diet with small amounts of seawater, but this is the exception rather than the rule.

Sharks, though not mammals, share a similar strategy: they are saltier than their surroundings and therefore do not drink seawater. Instead, they absorb water through osmosis across their skin, mirroring the approach of many freshwater fish.

7 Koalas Can Usually Get All the Water They Need While In Treetops

Koalas, those cuddly Australian icons, have a surprisingly frugal water budget. Their diet consists almost entirely of eucalyptus leaves, which, despite being famously toxic, are surprisingly moist. The foliage supplies a modest but sufficient amount of liquid to meet the marsupial’s needs.

During rainstorms, koalas will opportunistically lap water that runs down the trunks of trees, supplementing their diet. This behavior, combined with the inherent moisture in their leaves, usually means they rarely need to seek out a dedicated water source.

However, Australia’s recent heatwaves have forced many koalas to descend from the canopy in search of cooler, wetter micro‑habitats. Videos of koalas approaching humans for a sip from a water bottle have become viral, highlighting how climate pressures are nudging even the most adapted species toward supplemental drinking.

6 Frogs Absorb Water on Their Skin

Frogs spend a large chunk of their lives either immersed in water or perched near it, yet they are not avid drinkers. Their secret lies in a skin‑based hydration system that allows them to soak up moisture directly from their environment.

Australian green tree frogs, for instance, practice a quirky form of “lemonade physics.” They venture out into the cool night air, allowing water vapor to condense on their skin like droplets on a chilled glass. Those beads of moisture are then absorbed through the skin, delivering a refreshing boost of hydration.

Beyond this clever condensation trick, many frog species possess specialized “drinking patches” on their thighs and bellies. These highly vascularized skin areas act like sponges, drawing in water when the frog submerges itself or sits in a damp environment.

5 Kangaroo Rats Metabolize Water From Seeds

When most people think of rats, they picture disease‑laden city dwellers. The kangaroo rat, however, is a desert‑adapted marvel that never needs to drink water directly.

These tiny rodents survive in the scorching Sonoran Desert by extracting moisture from the seeds they consume. Their metabolism is astonishingly efficient: for every gram of seed ingested, roughly half a gram of water is produced internally.

To maximize water retention, kangaroo rats possess ultra‑concentrating kidneys that reabsorb virtually all water from their urine, excreting only a crystalline, almost solid waste. This physiological wizardry ensures that no drop of liquid is wasted.

4 Thorny Devil Channel Water Out of Sand

Among desert dwellers, the thorny devil stands out for its uncanny ability to “drink” from the very sand it traverses. This spiky lizard doesn’t gulp water; instead, it harvests moisture directly from damp grains.

The lizard’s skin is riddled with microscopic capillary channels. When its body contacts sand that contains even a trace of humidity, these tiny grooves draw the moisture upward, funneling it toward the mouth like a built‑in straw.

Because its oral cavity is adapted primarily for snatching ants, the thorny devil cannot drink from puddles or streams. The capillary network is therefore not just a clever adaptation—it’s a vital lifeline for surviving in some of the planet’s driest habitats.

3 Naked Mole Rats Get Their Moisture From Roots

Naked mole rats may look unassuming, but they are among the most resilient mammals on Earth. Living underground, they subsist on a diet of roots and tubers, which provide all the water they need.

These rodents practice a sustainable foraging habit: they nibble only part of a root, allowing the plant to continue growing and offering future meals. The moisture locked within those subterranean vegetables satisfies the mole rat’s hydration requirements without ever needing a free‑standing water source.

2 Sand Cats Will Drink Water But Don’t Need To

Sand cats may be small, but they are fierce desert hunters. Their bodies have evolved to thrive where water is a scarce commodity.

These feline predators can go weeks without drinking, extracting the necessary moisture from the bodies of their prey—rodents, birds, insects, and even tiny spiders. When water is available, they will drink it, but it is not a daily requirement.

Their desert‑adapted physiology, combined with a keen sense of hearing that helps locate hidden prey, allows sand cats to survive in some of the world’s most arid regions without the constant need for a water source.

1 Gerenuk Never Need to Drink

The gerenuk, often nicknamed the “giraffe‑necked” antelope, roams the African savannah with a slender build and an impressively long neck that lets it browse foliage out of reach of most herbivores.

Living in regions where water holes are few and far between, the gerenuk has taken water conservation to the extreme. It can spend its entire life without ever tasting a drop of water, relying instead on the moisture contained in the leaves and shoots it consumes.

To further minimize water loss, these antelopes have evolved specialized nasal passages that recapture moisture during exhalation, ultra‑concentrated urine, and a largely sedentary lifestyle that reduces unnecessary water expenditure.

People fork over huge sums of money to live in a place with a view over the water, whether it be the ocean, a bay, a lake, a lagoon, or a fjord. There is something inherently magical about waking up to the sun glittering over the sea or watching as thick mist rolls in over a lake.

But what if you’re gazing out at the water, feeling all kinds of peace, just to see a shadowy figure staring back at you? Or you hear someone humming a long-forgotten tune while you’re strolling along the shore, and you find yourself face to face with a red-eyed mermaid ready to stick sharp claws into your flesh.

Water mythology has been around for a very long time and centers around a slew of scary characters and fabled objects. On this list are just a few of these.

10 Burning Ship of the Northumberland Strait

If you’re not familiar with Canadian topography, Prince Edward Island, New Brunswick, and Nova Scotia aren’t places you would likely recognize. Unless you’ve read L. M. Montgomery’s acclaimed Anne of Green Gables, that is.

However, the Northumberland Strait, located between PEI, New Brunswick, and Nova Scotia, has put Canada on the paranormal map, as opposed to the literary one.

In 1900, a group of sailors from Charlottetown spotted a ship sailing toward the shore. As the ship drew near, the sailors saw her masts crawling with crew members trying to escape an inferno on the deck. The sailors sprang into action, jumping into a rowboat and oaring toward the burning ship. Just before they reached it, the ship disappeared before their eyes.

This wasn’t the first sighting of the ship. Reports have been trickling in since 1786, and the legend of the burning schooner has served as inspiration for novels, articles, and songs. It even has its own dedicated Canadian postage stamp.

A couple in Glengarry also saw the ship one evening in 1950, fully rigged and engulfed in flames, sailing down the Northumberland Strait. Unlike most urban legends, there is no backstory to this phenomenon. No sinking or tragedy that could have given rise to this eerie story. Instead, those who live in the area just try to keep an eye out for the burning ship and cross their fingers against bad luck.^[1]

9 Flathead Lake Monster

Scotland is not the only place that boasts a water-dwelling monster. Flathead Lake in Montana falls within the boundary of the Confederated Salish and Kootenai Tribes Flathead Reservation and is the largest natural freshwater lake west of the Mississippi in the lower forty-eight states.

In 1889, the skipper of the U.S. Grant steamboat and several passengers spotted what seemed to be a huge log in the waters of Flathead Lake. As they approached the object, they realized it was a living creature. It was coming toward them and moving fast. One passenger fired at it with a rifle but missed. And so was born the legend of the Flathead Lake Monster.

Those who have encountered the monster describe it as a massive eel-shaped creature of up to forty feet (12.2 meters). Some say it looks like a giant sturgeon with a head like a bowling ball. There have been many more sightings over the years, and the monster has earned the nickname “Flessie.”

In a strange turn of events, a three-year-old boy who couldn’t swim was found soaking wet at the end of a dock at the lake in 2017. When he was asked what had happened to him, he said that he’d fallen into the lake and a monster had lifted him up and out to safety.^[2]

8 Miniwashitu

In 1921, curator Melvin Randolph Gilmore wrote about a creature named Miniwashitu. This mysterious being was allegedly seen in the Missouri River, glowing like fire and producing an unearthly sound. Soon people began believing that those who saw the beast in the daytime would become inflicted with insanity and unexplained physical pain.

The monster is said to have red hair and one eye in the middle of its forehead, with a horn protruding above it. Its backbone looks like a giant saw.

Even in modern times, Missouri locals still tell the story of the Miniwashitu. It is believed that the monster still lurks in the river and moves upstream during springtime. Sometimes it moves around in winter, breaking ice that has formed over the water.^[3]

7 Ashrays

There is more to Scotland than just unicorns and the Loch Ness Monster. Here you might just bump into what looks like an underwater ghost known as an Ashray. Ashrays cannot live on land and are only found beneath the water’s surface. They resemble the ghosts of humans, as they are entirely translucent, and the best time to look for them is, of course, in the dark of night as they are nocturnal creatures.

In English folklore exists the Asrai, which is supposed to be an aquatic fairy. Legend has it that a fisherman once captured an Asrai and put it in his boat. The Asrai pleaded with the fisherman in a language he could not understand, but the fisherman proceeded to tie wet weeds around the fairy, burning his hands in the process when he touched its skin. Eventually, the Asrai melted into a puddle of water. It is believed that these creatures perish if exposed to the sun for too long.

They are said to have green hair and a mermaid-like fishtail. They only come up to the surface once every hundred years to bathe in the moonlight.^[4]

6 Spiteful Mermaid

Most people have heard of the so-called “water babies” found in lakes and rivers in America. Urban legend says that ancient members of the Paiute Tribe would drown disabled babies in bodies of water, only for the babies to return in spirit form and cry out over the water when night falls.

Pyramid Lake in Nevada is not only one of the locations where the wail of water babies has been heard, but it is also where a brokenhearted mermaid is believed to have spoken a curse after her marriage to a Paiute Tribe member was frowned upon. She was banished from the land and, in turn, vowed revenge should any tribe members go anywhere near the lake. To this day, many Paiute members still believe that any bad luck suffered by the tribe can be attributed to the mermaid’s curse.

Perhaps the scariest part of Pyramid Lake is that it is the last remnant of the ancient Lake Lahontan, and it was also the deepest part. This means that no one really knows what lies in the sediments far below.^[5]

5 Ship of Death

In 1862, Leon Webber watched as a veil of mist enveloped the Platte River in Wyoming. He moved closer to the river’s edge and, out of curiosity, tossed a small stone at the mist. It instantly transformed into a ship covered in frost.

Webber could only stare as several sailors onboard, who were also covered in frost, closed ranks around an object lying on the deck. When they scattered, Webber saw that the object was the body of a young woman. Then with a shock, he realized he was looking at his own fiancé.

Trying to push the experience from his mind, Webber returned home a month later only to find that his fiancé had died on the very same day he’d seen the vision of her corpse.

Since then, the aptly nicknamed Ship of Death has been sighted every 25 years. Creepily, all the sightings are reported to have taken place in the middle of the day, when temperatures usually soar, which makes it somewhat more difficult to explain away the thick, rolling mist and the shadows some witnesses have seen form over the water.^[6]

4 Hafgufa

An Icelandic legend has it that a ginormous sea monster named Hafgufa once existed in the Greenland sea. The monster was said to be a massive fish whose top part resembled an island. Sightings of Hafgufa were rare, but a sailor once witnessed her belch and expel a huge amount of food which attracted thousands of fish. The fish crowded into Hafgufa’s mouth, and she swallowed them all in one go.

It is believed that Hafgufa was the mother of all sea monsters and ate anything she could catch, including ships, humans, and whales. Because she resembled an island, many sailors would mistake her nose and head, which she raised above the surface at low tide, for rocks.^[7]

3 The Octavius

In 1761, the Octavius docked in the port of London and took on cargo destined for China. The ship left London with a full crew on board, as well as the family of the captain. They made the trip safely to China, and once they took on cargo meant to be offloaded in Britain, the captain decided to sail the Northwest Passage. After entering the passage, the ship vanished without a trace.

Fast forward to 1775. The whaling ship, Herald, was sailing the waters of Greenland when her crew saw another ship a distance away. As they sailed closer to the ship, they saw that she was in bad shape. Some of the crew boarded the vessel to investigate and made a horrific discovery below deck. In the crew’s quarters, all 28 crew members of the Octavius were found in a frozen state. The captain was seated at his desk, frozen to his seat. Behind him were his wife and son, both frozen.

The Herald crew members were shocked and terrified. They grabbed the ship’s log and fled. In their haste, the book’s middle pages loosened and were lost. What remained of the writing in the logbook told the story of the ship becoming stuck in the Arctic ice near Barrow, Alaska. Fearing that the Octavius was cursed, the crew of the Herald simply let it drift off. It was never seen again and might still be floating in the open water somewhere, its unlucky passengers still onboard.^[8]

2 Lorelei

On the echoing rock, Lurlei, on the southern bank of the River Rhine, you might just spot Lorelei. German lore tells the story of a woman who had been betrayed by her lover. Her heart shattered, she drowned herself in the river and was reincarnated into a siren. The murmuring echo that emanates from Lurlei is said to be Lorelei’s song, calling men onto the rocks and their subsequent doom.

Heinrich Heine wrote a poem called “Die Lorelei” in 1824, which has since been set to music by several composers.

“The comb she holds is golden,
She sings a song as well
Whose melody binds an enthralling
And overpowering spell.
In his little boat, the boatman
Is seized with a savage woe,
He’d rather look up at the mountain
Than down at the rocks below…”^[9]

1 The Celtic Merrow

Ireland is steeped in folklore. Here you will hear tales of wailing banshees, mischievous leprechauns, and creepy fairies. It is also the place you’ll find the Celtic merrow who used to live in the Celtic seas according to legend.

A merrow is a mermaid with a magical cap that enables her to travel between the sea and the shore. When the merrow combed her soft hair, sailors and fishermen were entranced. The comb used was of the magical variety and a symbol of feminine power.

The merrow is said to be either male or female, with the difference being that the women were exceptionally beautiful, but the men were hideously ugly. The merrow men became bitter when the women looked toward human men for mates. They resorted to capturing sailors and keeping them imprisoned underwater in revenge.

Should a male human wish to keep one of the merrow women with him on land, he would need to take away her magical cap before she could enchant him by singing. Possessing her cap meant the man would eventually be able to persuade her to marry him as well. However, the couple’s wedded bliss would be short-lived, as the merrow woman would search until she found her cap and then drag her husband underneath the waves with her.^[10]
