Trivia Questions for Adults

Chocolate syrup Hitchcock shot Psycho in black-and-white and used chocolate syrup for the infamous shower scene because its thick consistency and color showed up convincingly as blood on camera . Wikipedia

Vito Corleone Because Marlon Brando and Robert De Niro each won Oscars for playing Vito Corleone (Brando as Best Actor in The Godfather and De Niro as Best Supporting Actor in The Godfather Part II), marking the first time two actors won for the same character . Wikipedia

The Guinness Book of World Records Librarians report that the Guinness Book of World Records is so popular as a trivia reference that it "has the distinction of being the most frequently pilfered book from public libraries," as one news story noted .

Sherlock Holmes Guinness World Records lists Sherlock Holmes as the most portrayed literary human character ever, with over 250 film and TV appearances by more than 75 actors, his on-screen ubiquity even beats Dracula's (who isn't human). Wikipedia

Jane Wyman During the 1948 film Johnny Belinda, Jane Wyman portrayed a deaf-mute character and never spoke a word, she won the 1949 Best Actress Oscar, becoming the first sound-era performer to win an Academy Award for a silent role . Wikipedia

O.J. Simpson In early casting, Terminator director James Cameron reportedly felt that audiences "wouldn't have believed a nice guy like O.J. as a ruthless killer", so Arnold Schwarzenegger got the role, and Simpson never became the Terminator. Wikipedia

The Silencers (1966) The Silencers, a 1966 spy spoof, is credited as the first general-release movie to include a post-credits stinger, it ends with Dean Martin (as secret agent Matt Helm) on a rotating bed surrounded by women and a "Coming Up Next" teaser text .

Tetris (on the Game Boy) In 1993, Russian cosmonaut Aleksandr A. Serebrov took a Nintendo Game Boy and a Tetris cartridge aboard the Soyuz TM-17 mission to the Mir space station, on July 1, 1993 Tetris became the first video game played in space .

Salvator Mundi by Leonardo da Vinci (approximately $450.3 million) At a Christie's auction in November 2017, Salvator Mundi ("Savior of the World") attributed to Leonardo da Vinci sold for about \$450.3 million, setting the record for the most expensive painting ever sold .

He used alliteration as a memory trick Stan Lee admitted he found it easier to remember his characters' names if they had the same first letter (like Matt Murdock or Green Goblin's alias Norman Osborn), so he deliberately gave many Marvel heroes and villains alliterative names as a mnemonic device .

The Mousetrap by Agatha Christie Agatha Christie's The Mousetrap opened in London's West End in 1952 and has run continuously since then (except a 2020 pause), surpassing 30,000 performances by 2025, no other show comes close to its record-run longevity .

The Popsicle On a cold night in 1905, 11-year-old Frank Epperson left a mixture of soda water and powder in a cup with a stir stick on his porch; by morning it had frozen solid, creating the first "Epsicle," later renamed Popsicle, a classic accidental invention . Wikipedia

Alabama Alabama has many odd old laws on the books, one statute makes it a misdemeanor to disrupt a church service, and legend has it this included wearing a funny fake mustache during church to prevent worshippers from giggling (a holdover from earlier times, rarely if ever enforced today) . Wikipedia

The letter J Out of all one- or two-letter element symbols (like H for hydrogen or Au for gold), none include the letter J, J is the only letter completely missing from periodic table symbols . (For example, iodine uses "I" and lithium uses "Li," but no element uses J.)

Venus Venus rotates extremely slowly, one Venusian day (one rotation) takes about 243 Earth days, while one Venus year (one orbit of the Sun) is ~225 Earth days. In other words, Venus's day outruns its year, the only planet in our solar system where that happens. Wikipedia

The lyrebird The male superb lyrebird is nature's master impersonator, it can copy the songs of dozens of bird species and also imitate man-made sounds (like car alarms, camera clicks, and chainsaws) with astonishing accuracy as part of its mating display .

Pumice Pumice is a volcanic rock full of trapped air bubbles, making its density lower than water. If you drop a dry pumice stone in water, it can bob on the surface instead of sinking, a rare property for a rock (until it eventually becomes waterlogged). Wikipedia

About one million The Sun is enormous, about 1.39 million km in diameter. Roughly 1.3 million Earths could fit inside the Sun's volume if it were hollow , so we often round it to "about one million Earths" as a handy illustration of the Sun's immense size.

The Atacama Desert in Chile The Atacama Desert is so arid that its central parts get virtually zero precipitation, one town went 173 consecutive months with no rain. It's the driest desert in the world outside Antarctica, with some areas seeing rain only a few times a century .

Canada Thanks to its vast size and northern geography, Canada contains well over 2 million lakes, more than 50% of all natural lakes on Earth . (By comparison, Russia, the next closest, has less than half that number.) This makes Canada the world's lake champion. Wikipedia

NASA's Voyager 1 spacecraft Launched in 1977, Voyager 1 has traveled so far (over 15 billion miles away) that in 2012 it passed into interstellar space. It's the most distant man-made object in existence, farther out than Pluto, still sending data back as it heads into the Milky Way .

True A lightning strike superheats the air to around 30,000 degrees C (54,000 degrees F) in an instant, about five times hotter than the Sun's visible surface (~5,500 degrees C) . This extreme heat causes the explosive expansion of air that we hear as thunder. Wikipedia

The Mariana Trench is deeper The Mariana Trench's deepest point (Challenger Deep) is about 11 km (~36,000 ft) below sea level. That's deeper than Mount Everest's 8.8 km height, meaning if Everest were placed at the trench's bottom, its peak would still be more than 2 km underwater .

A pack of Wrigley's Juicy Fruit chewing gum On June 26, 1974, a supermarket in Troy, Ohio made history when a cashier scanned a 10-pack of Juicy Fruit gum, which rang up at \$0.67, the first use of the now-ubiquitous Universal Product Code barcode in a retail transaction . The gum pack is now in the Smithsonian Museum.

The sperm whale The sperm whale can produce powerful clicking calls up to 230 decibels, far louder than a jet engine and topping even the famously loud blue whale . (For context, 230 dB is about the highest sound level measured in any animal, human eardrums would rupture long before that volume.)

The ocean quahog clam (e.g. "Ming" the clam) A specimen of Arctica islandica, known as Ming the clam, was found to be 507 years old, it hatched around 1499 and lived until 2006. This deep-sea clam's multi-century lifespan makes it the longest-lived non-colonial animal ever documented.

France (when including its overseas territories) Thanks to its far-flung territories (from Polynesia to the Caribbean), France covers 12 time zones, more than any other nation . (By contrast, Russia, the largest country by land, has 11, and the USA has 11 including territories.)

Uzbekistan Uzbekistan in Central Asia and Liechtenstein in Europe are the only "double landlocked" countries . Uzbekistan's neighbors (e.g. Kazakhstan, Afghanistan) are all landlocked themselves, and the same is true for tiny Liechtenstein's neighbors in Europe. Wikipedia

Grover Cleveland Grover Cleveland was elected in 1884, defeated in 1888, then came back to win again in 1892, making him the 22nd and 24th President of the United States . He's the only one to leave the White House and return four years later, which is why the presidents count skips a number. Wikipedia

South Africa South Africa uniquely splits its government: Pretoria is the administrative/executive capital, Cape Town is the legislative capital, and Bloemfontein the judicial capital . This arrangement was a compromise to spread out power when the country formed. Wikipedia

Istanbul (in both Europe and Asia) Istanbul straddles the Bosporus Strait, one part lies in Europe and the other in Asia. It's often called the city "where East meets West," and it's the only metropolis in the world that spans two continents across a body of water .

Equatorial Guinea A former Spanish colony, Equatorial Guinea retains Spanish as an official language (alongside French and Portuguese). It's the only Spanish-speaking nation in Africa, whereas other African countries tend to use English, French, or Arabic from different colonial histories . Wikipedia

It isn't a rectangle (Nepal's flag is two triangular pennants) Nepal is the only country with a non-rectangular national flag . Its flag consists of two stacked triangles with stylized sun and moon symbols. Every other nation uses a rectangle or square, making Nepal's double-triangle flag one-of-a-kind in vexillology.

Wellington, New Zealand Wellington sits at about 41.3 degrees South latitude, near New Zealand's southern tip. That makes it the world's southernmost national capital, it's farther south than Canberra, Australia or Montevideo, Uruguay (and only research bases in Antarctica are further south, but no country's capital) . Wikipedia

They were skipped when Britain switched to the Gregorian calendar Great Britain (and its colonies, including America) switched from the Julian to the Gregorian calendar in 1752, which required dropping 11 days to align dates . Crowds supposedly yelled "Give us our eleven days!" but the change stuck, ever since, British dates matched those of Europe.

Because Chimborazo sits on a bulging equator, its summit is Earth's farthest from the core Earth is not a perfect sphere, it bulges at the equator. Chimborazo, near Earth's equatorial bulge, has a summit that is about 2 km farther from the planet's center than Mount Everest's peak (Everest is higher above sea level, but Chimborazo wins in radius from Earth's core) .

Louis XIX of France, about 20 minutes In July 1830, King Charles X abdicated during the French Revolution of 1830. His son Louis Antoine briefly became King Louis XIX, but he signed his own abdication after roughly 20 minutes to pass the crown to his nephew. It's the shortest verified reign on record (talk about a quick turnover!).

Chile and Ecuador Brazil's huge area touches 10 of the 12 other South American nations, the exceptions are Chile (way on the Pacific coast beyond the Andes) and Ecuador. Every other neighbor, from Uruguay to Venezuela, connects to Brazil's borders on the continent.

The wombat A wombat's intestines mold its feces into little cubes, yes, square poop. This likely helps wombats mark their territory without the pellets rolling away . It's a bizarre but true quirk of nature (and a great conversation starter: "Have you heard about wombat poop?").

The sloth About once a week, a sloth climbs down from the safety of its tree to poop on the ground, a long, clumsy trip. Over 50% of sloth fatalities happen while they're "taking a poop" because they're so vulnerable to predators during that slog. (Talk about deadly constipation!)

True Scorpions have extremely low metabolic rates and special book lungs, so they can survive with almost no oxygen for days. They've been observed lasting 6, 7 days without breathing ! (In comparison, humans start getting brain damage after a few minutes, scorpions are the ultimate breath-holders.) Wikipedia

The shrimp A shrimp's heart is in its cephalothorax (the combined head and body segment) near the back of the head . So, as a lighthearted saying goes, shrimps literally wear their heart on their sleeve, or rather on their head.

Yes, a giraffe's tongue is about 20 inches long Giraffes have huge prehensile tongues (usually dark bluish in color) that can reach up to 50 cm. They use them to grab leaves and can even lick inside their ears for a little ear cleaning . (Imagine self-ear-cleaning with your tongue, the giraffe can do it!)

Certain snails Some land snails can enter a state of dormancy called estivation in extreme dry conditions. They effectively "sleep" sealed in their shells for up to 3 years waiting for moisture . (They wake up very hungry, who wouldn't after a three-year nap?)

Yes, dolphins snooze one half of their brain at a time Dolphins (and some whales) practice unihemispheric slow-wave sleep, meaning one brain hemisphere sleeps while the other stays awake. They often keep one eye open and one closed as they rest , allowing them to surface for air and watch for danger even while "half-asleep."

A pebble Certain penguins (like Adelie and Gentoo penguins) present their crush with a smooth pebble as a love token. If the female approves, she uses it in her nest. It's like the penguin version of an engagement ring, except it's a rock given instead of a rock on a ring!

True Jellyfish are primitive invertebrates consisting mostly of a gelatinous umbrella and tentacles. They have no brain (just a nerve net) and no heart or blood. They still manage to eat, sense, and reproduce with a very simple body plan, basically a living Jell-O blob with stingers. Wikipedia

The kangaroo A kangaroo's muscled tail and body design allow great forward hopping but literally block it from jumping backward. Kangaroos cannot hop or walk in reverse , which is why Australia chose the kangaroo (and emu, which also can't walk backward) on its coat of arms to symbolize onward progress.

They have three hearts and blue blood An octopus has one main heart plus two auxiliary hearts to pump blood through its gills. And instead of red iron-based blood, octopuses use hemocyanin, a copper-rich protein, so their blood is blue in color. They truly are aliens of the deep, with triple hearts and royal-blue blood.

Roughly 14 times Yes, everyone farts. An average human toots out about half a liter of gas across ~14 fart episodes a day (www.who-smelt-it-dealt-it.com). Most are polite little puffs (often unwitnessed), but it's a normal part of digestion. In fact, if you hold it in, the gas will find another way out or give you a gutache.

Guinea pigs Guinea pigs are so social that Swiss animal welfare law says you cannot keep a lone guinea pig by itself . (They even have "rent-a-guinea-pig" services in Switzerland, if one pig dies, you can borrow a widowed piggy friend so the other isn't lonely!) Wikipedia

Cross the road Believe it or not, a local ordinance in Quitman prohibits chicken owners from letting their foul... I mean fowl, wander onto the roads. In other words, "the chicken can't cross the road" (without breaking the law) in this town . The goal was to prevent traffic hazards, and yes, this gives a whole new twist to the classic joke!

Milan, Italy Milan had an old municipal regulation that reportedly required people to appear cheerful in public. Residents were to keep a smile on except during solemn occasions. It's not enforced today, but for a long time, not smiling in Milan could theoretically get you in trouble, a very quirky (and very Italian) law aimed at keeping "la bella figura" (a good appearance).

Yes, mostly, Singapore banned gum to keep the city clean In 1992 Singapore's government outlawed the sale and import of chewing gum (except for therapeutic nicotine gum later on). Sticking gum was causing public nuisance, so the strict ban was passed. You actually need a medical prescription to get gum there, one of the world's strangest (and cleanest) laws.

Simply trying to escape prison is not a crime (if no other laws are broken) German law recognizes the human instinct for freedom, a prison inmate will not be given extra punishment just for a mere escape attempt . (Of course, if they damage property or commit other crimes during the escape, those are charged, but the act of fleeing itself, in theory, isn't an additional offense in Germany.)

Because wearing high heels at some ruins (like the Acropolis) is illegal The Greek authorities banned sharp heels at archaeological sites to protect the fragile ancient stone. High-heel shoes can damage marble and other historic materials, so tourists must wear flats or sneakers when touring places like the Acropolis in Athens . (Fashion can hurt, especially 2,500-year-old floors!)

Japan In 2008 Japan passed the "Metabo" law requiring companies to measure the waistlines of employees over 40. Men must stay under 85 cm (33.5) and women under 90 cm (35.4) or get counseling. The idea is to reduce health issues, essentially making it quasi-illegal to be too chunky in Japan. Wikipedia

To prevent disturbances during worship It sounds silly, but Alabama once outlawed fake mustaches in church specifically to stop pranksters from making the congregation laugh . The spirit of the law was about keeping order during services. (This law is old and rarely enforced, but it's on the books, proving lawmakers long ago had a sense of humor!)

Moose After incidents like a moose getting drunk off fermented grain and causing a ruckus, Alaska passed a law forbidding giving alcohol to a moose . It's a real law on the books, apparently to protect both the moose and the public (because a tipsy 1,000-pound moose is bad news for everyone). Wikipedia

The cemetery was full, so the mayor decreed, "No dying unless you already have a plot" The mayor of Sarpourenx, France, was desperate after they couldn't get cemetery expansion approval. He issued a tongue-in-cheek ordinance forbidding people to die in his village unless they had pre-purchased a grave, under "penalty" of... well, being dead. It was a protest to draw attention to the cemetery shortage (and it worked!).

New Mexico (and a few others, using outdated term) New Mexico's state constitution (Article VII, Section 1) still says "idiots" (an antiquated term for persons with mental incapacities) are not permitted to vote. This offensive old language remains on paper even though it's not enforced and contradicts federal law. (It's a strange remnant of 19th-century legal lingo that modern lawmakers haven't gotten around to scrapping.)

A metal nail (about 3 inches long) The human body contains around 3, 4 grams of iron, mostly in our blood's hemoglobin. If you extracted it all, you'd have just about enough iron to cast a 3-inch (8 cm) iron nail . (So yes, we're all walking hardware stores in that sense!)

True, we actually glow, but it's extremely faint Human biochemistry produces a tiny amount of visible-spectrum light through cellular reactions. Ultra-sensitive cameras have confirmed that people give off a faint bioluminescent glow , peaking at late afternoon, it's about 1,000 times too weak for our eyes to see, but it's there!

A banana It's hard to believe, but about 60% of human genes have analogues in the banana plant. We share over half our DNA with bananas, and even more with fruit flies and mice! This is because fundamental cellular processes are similar across life. (It doesn't mean you're half banana, just that many basic instructions are the same.)

Earwax Earwax (cerumen) is made by modified sweat glands in your ear canal. So, biologically speaking, earwax is dried sweat mixed with fatty secretions . No wonder it's a bit salty. Its job is to trap dust and microbes, think of it as sweat that went into sticky security duty. Wikipedia

Over 2,300 species (and counting) A "Belly Button Biodiversity" study found 2,368 bacterial species in 60 people's navels, many of them new to science . The belly button, often ignored, can be a literal jungle of microbes, unique to each person like a microbial fingerprint. (So don't forget to scrub it!)

True (approximately) The average person secretes 1, 2 liters of saliva a day. Over ~70 years, that's on the order of 36,000, 51,000 liters. In other words, yes, enough spit to fill two standard backyard swimming pools . (But please, no one try to prove this literally!)

Around 14 times Most people pass gas about 14 to 20 times daily, totalling roughly 500, 1500 mL of gas (www.who-smelt-it-dealt-it.com). That's normal digestion at work. (If you're doing a lot more, you might have had too many beans, or you're just counting vigilantly. And if you say "zero," you're in denial!)

Your tongue The surface of your tongue, its pattern of elevations and grooves, is unique to you. Tongue prints are like snowflakes , which has led to research into tongue-print biometrics. (So far, we don't lick ID scanners... but in theory, you could!)

Yes, for example, it could eat through a razor blade Gastric acid is mostly hydrochloric acid around pH 1.5, 2. It's corrosive enough to dissolve thin metal like zinc or iron given time. In lab tests, a swallowed razor blade's edges became dull after a day in stomach acid. (Our stomach lining survives because of a protective mucus layer, thankfully!)

To the Sun and back, many times over (on the order of 10 billion miles) There is about 2 m of DNA in each human cell nucleus ~37 trillion cells. If you stretched it all out, it'd be roughly 10 billion miles long, that's over 100 round trips to the Sun, or all the way to Pluto and back nearly 17 times . Mind = blown!

True, 52 of the 206 bones (25%) are in our two feet Each human foot has 26 bones (plus a few tiny sesamoids). Together that's 52 bones in your feet out of 206 total. So roughly 1 in 4 bones in your body is in your feet . No wonder feet are so flexible, they're a complex jigsaw of bones!

In the morning Overnight, lying down lets your spine decompress. By morning you can be about 1 cm taller than you were at the end of the day . As the day goes on, gravity and compression make you slightly shrink again. (So if you need that extra 1 cm, schedule your height measurement early!)

The Anglo-Zanzibar War of 1896, it lasted about 38 minutes On 27 August 1896, after the Sultan of Zanzibar refused to step down, the British bombarded his palace. The Sultan surrendered in under 40 minutes . It's often cited as the shortest war ever, basically the length of a sitcom episode!

A soldier chased his runaway dog across the border, sparking gunfire Tensions were high at the Greek, Bulgarian border when a Greek soldier's dog ran into Bulgaria. He ran after it, shots were fired, and things escalated. This literal "war over a stray dog" led to brief fighting (and a League of Nations intervention), a truly absurd cause for a war .

Saddam Hussein Believe it or not, in 1980 the city of Detroit honored Iraq's then-President Saddam Hussein with a ceremonial key to the city . He had donated generously to a local church. It's a cringe-inducing historical fact in hindsight, years later, that same Saddam became a vehement U.S. enemy. Wikipedia

A pig Medieval records show a sow was tried in Falaise, France for killing a child, found guilty, and hanged in public while dressed in men's clothes. Pigs, goats, even insects!, were taken to court back then. It sounds absurd now, but animal trials were surprisingly common in Europe until the 18th century.

Emus (yes, giant flightless birds) Wild emu flocks were ravaging Australian farmlands, so soldiers with machine guns were sent to cull them. But the emus proved too elusive and hardy. After weeks of futile chase, the military withdrew. The emus "won", one commander joked they "had hardly suffered any casualties." This "Great Emu War" remains a legendary comedy of errors in Australian history.

Glowworms (in jars) In the dark trenches of World War I, British troops collected glowworms, bioluminescent insects, and kept them in clear jars. The faint green glow was enough to read maps and letters but not bright enough to give away their position to the enemy. A creepy-crawly but effective "night-vision" solution before modern tech.

A crackpot amateur thought he solved squaring the circle, and lawmakers almost enshrined it An amateur mathematician convinced Indiana's legislature he had a new formula for area of a circle, inadvertently making = 3.2. The Indiana Pi Bill actually passed the State House before an informed professor stopped the State Senate from making it law. It is often cited as a prime example of legislative ignorance, almost legislating math by majority vote.

He kept honey-covered slaves nearby to attract the flies According to historical anecdotes, Pepi II (c. 2300 BC) so hated insects that he'd have naked servants smeared with honey standing around him . The flies would swarm on the honeyed humans instead of bothering the pharaoh. Bizarre but (reportedly) true, talk about taking one for the team!

David Rice Atchison When President James K. Polk's term expired on Sunday March 4, 1849, incoming President Zachary Taylor deferred his oath to Monday. By some interpretations, Senate President Pro Tem David Atchison was Acting President for about 24 hours (though he never took the oath, and most historians consider it unofficial). It's a quirky footnote that Atchison joked about himself, he purportedly slept through most of his "presidency." Wikipedia

He rode in a car for many miles The 1904 St. Louis Olympic marathon was insanely mismanaged, it was hot, dusty, with only two water stops. Runner Fred Lorz grabbed a lift in a car for 11 miles, then jogged into the stadium and broke the tape as "winner." Officials caught on when he cheerfully admitted he'd taken a car ride, and he was disqualified (Thomas Hicks, who won, had his own drama, he was doped with strychnine!).

Modenese soldiers stole a bucket from Bologna as a trophy, sparking Bologna to declare war Medieval rivalry was intense, Modena snatched a prized bucket from Bologna's city well during a raid. Insulted, Bologna raised an army of 30,000 to get it back. The War of the Bucket saw a major battle (Modena won and kept the bucket) . The battered bucket is still on display in Modena, a legendary symbol of perhaps the pettiest war ever.

True An Ohio physician named Dr. John Cook Bennett believed tomatoes had health benefits. In 1834 he cooked up a concentrated tomato pill and marketed ketchup as a cure-all for indigestion, diarrhea, etc. . "Tomato ketchup" was literally sold as medicine! (It didn't last long, by the 1850s ketchup reverted to just a tasty condiment.) Wikipedia

The "immortal jellyfish" (Turritopsis dohrnii) It escapes death by reverting its mature cells back into a youthful polyp stage, rendering it biologically immortal . Wikipedia

The tardigrade (water bear) Tardigrades endure absurd extremes of temperature, pressure, radiation, and dehydration, and they've even survived exposure to outer space . Wikipedia

The wood frog During winter it literally freezes with no heartbeat or breathing, avoiding cell damage by producing antifreeze-like chemicals, then thaws back to life in spring . Discoverwildlife

The Surinam toad (Pipa pipa) During breeding the female's fertilized eggs embed in her back and skin grows over them; a few months later, fully formed toadlets emerge from her back . Wikipedia

The horned lizard When threatened it restricts blood flow in its head until tiny vessels burst, squirting a foul-tasting stream of blood up to five feet to frighten predators . Wikipedia

The Pycnandra acuminata tree of New Caledonia Growing on nickel-rich soils, it hyperaccumulates nickel into its sap, up to a quarter of its dry weight, which turns the sap turquoise blue . Wikipedia

The emerald green sea slug (Elysia chlorotica) By stealing and storing chloroplasts from the algae it eats, this slug uses sunlight to produce energy, essentially performing photosynthesis in its own body . Wikipedia

Tiny frogs Certain tarantulas allow little narrow-mouthed toads to live in their burrows, the spiders don't eat them because the frogs eat ants and other pests that would harm the spiders' eggs .

The axolotl (Mexican salamander) Because axolotls remain in a youthful aquatic state with external gills (neoteny), they heal without scarring and can regenerate entire limbs, heart tissue, and portions of their nervous system . Wikipedia

Ophiocordyceps unilateralis (the zombie-ant fungus) After infecting an ant, the fungus chemically controls the ant's behavior, it makes the ant climb up and bite onto vegetation, then the fungus kills the ant and sprouts from its head, raining spores on new victims .

A gigantic honey fungus (Armillaria) in Oregon A single underground Armillaria fungus spreads through 3.4 square miles of soil, nearly four square miles. That makes it the most extensive organism ever found .

Yes, humans emit a faint visible bioluminescent glow Chemical reactions in our metabolism release a tiny amount of light (photons), so every person is very weakly glowing at all times, though it's far too dim for our eyes to notice .

Lake Natron in Tanzania Lake Natron's water can reach a caustic pH of up to 10.5 (almost like ammonia), so animals that die in it become encrusted with soda and salts, leaving eerie, stone-like preserved carcasses .

The "Door to Hell" In 1971 a collapsed gas drilling site was set on fire to burn off methane, but it never went out, the pit has continued flaming for over 50 years, earning it the nickname "Door to Hell" . Wikipedia

Yoro, Honduras Each year during heavy storms, people in Yoro find live fish flapping on the ground, likely sucked up by waterspouts or updrafts and dropped far inland, leading to a yearly festival around this bizarre fish rain .

Cars appear to roll uphill on their own The surrounding landscape tricks your eyes, it's actually a downhill slope but looks like an uphill, so cars in neutral seem to defy gravity and roll "up" the hill due to the misleading horizon and terrain .

On the Taylor Glacier in Antarctica This Antarctic glacier oozes an iron-rich saltwater brine; the iron oxidizes (rusts) when it meets air, tinting the water a vivid red, so the icy waterfall looks like pouring blood .

Roopkund in India (the "Skeleton Lake") This remote glacial lake sits at ~5,000 meters elevation and contains the bones of hundreds of people from centuries ago, when the snow melts, skeletons appear in the clear shallow water around the lake's edge . Wikipedia

Movile Cave Sealed for about 5.5 million years, Movile Cave's air has only 7, 10% oxygen (vs 21% normally) and up to 100 more carbon dioxide, plus hydrogen sulfide, an extreme habitat where chemoautotrophic bacteria form the base of a unique ecosystem . Wikipedia

Thin sheets of ice and gentle wind In rare winter conditions, a shallow puddle freezes under the rocks and then cracks into panels; a light breeze pushes the floating ice sheets, sliding the rocks forward and leaving long tracks on the mud .

It's extremely hot and humid, about 58 degrees C (136 degrees F) with near 100% humidity The giant gypsum crystals formed in volcanic heat, and the cave's environment is "like an oven." Without protective cooling suits, a person would collapse from heatstroke in minutes inside the cave's 136 degrees F, sauna-like air . Science

Lake Maracaibo in Venezuela Thanks to ideal conditions (mountains and warm lake air), the "Catatumbo Lightning" storms rage over Lake Maracaibo roughly 297 nights a year, the area sees about 232 lightning flashes per square kilometer annually, far more than anywhere else on Earth . Geology

Certain dunes in deserts like the Gobi and Sahara "sing" (booming dunes) When masses of dry sand avalanche down the dune slopes under the right conditions, the sand grains vibrate together and produce a deep, resonant booming sound that can be heard for miles, the dunes literally roar or sing . Wikipedia

Socotra (in Yemen) Socotra's isolation gave rise to otherworldly flora and fauna found nowhere else, for example, its iconic dragon's blood trees have umbrella-like canopies and bleed red sap. The landscape is so strange that Socotra is frequently described as the world's most alien place .

Mercury is cooler than Venus Most assume the planet nearest the Sun would be hottest, but Venus's dense CO2 atmosphere traps heat with an extreme greenhouse effect, making Venus hotter than Mercury despite being farther from the Sun . Wikipedia

A Venusian day is longer than a Venusian year Venus spins so slowly (one rotation takes 243 Earth days) that a day on Venus outlasts its 224.7-day year, meaning Venus completes its orbit around the Sun before it finishes one whole rotation on its axis . Wikipedia

No, Earth would stay lit and orbit normally for about 8 minutes It takes roughly 8 minutes and 20 seconds for sunlight (and the Sun's gravitational influence) to reach Earth, so we'd have eight more minutes of daylight before darkness and eight minutes of orbit before Earth careened off course . Wikipedia

Yes, it's called the Mpemba effect It sounds crazy, but it's true: given the right conditions, a container of hot water can sometimes freeze more quickly than cold water. Scientists are still debating all the reasons, but the effect has been observed for centuries . Math

Yes, time runs slightly faster at higher altitudes According to Einstein's general relativity, gravity slows time. On a skyscraper's top floor you're farther from Earth's mass, so gravity is weaker and time ticks a tiny bit faster than at street level (the difference is measurable with atomic clocks) . Wtamu

Roughly the size of a sugar cube Atoms are 99.9999999999999% empty space, matter is insanely sparse. If you compressed all 8 billion people down to only their matter, the human race would fit in a cube about the size of a sugar cube (though it would weigh billions of tons) .

True The average Earth, Moon distance is about 384,000 km. If you take the diameters of Mercury through Neptune and put them next to each other, they total around 380,000 km, which means amazingly, all the planets would just fit in between (with a little room to spare) . Universetoday

Only about 42 times It's a mind-bending result of exponential growth, each fold doubles the thickness. By 42 folds, a paper's thickness would increase 2^42 times (over 4 trillion times), which works out to about 440,000 km thick, roughly the Earth-Moon distance . Kano
