Here are more of Earth’s tiniest creatures that play a big role in the environment.
Fact: The circulatory system is more than 60,000 miles long
If a child’s entire circulatory system—we’re talking veins, arteries, and capillaries—were laid out flat, it would stretch for more than 60,000 miles, according to the Franklin Institute. By the time we reach adulthood, our bodies have become home to approximately 100,000 miles of blood vessels. That’s just one of the mind-blowing facts that sound made up (but aren’t).
Fact: There are parts of Africa in all four hemispheres
For people whose education was largely focused on the Western world, it may be surprising to find out exactly how huge the continent of Africa is. For instance, it spans all four hemispheres and covers nearly 12 million square miles. Here’s another interesting fact: Do you know the only city that straddles two continents?
Fact: The cornea is one of only two parts of the human body without blood vessels
The cornea is the clear part of the eye that covers the pupil and other parts of the eye.

It was a political satire called El Apóstol made up of 58,000 drawings and had a running time of 70 minutes, according to the Guinness Book of World Records.
Fact: German chocolate cake was invented in Texas
The “German” part of German chocolate cake comes from an American man—not a European country. Specifically, it’s named after Sam German, who in 1852 created the formula for a mild dark baking chocolate bar for Baker’s Chocolate Company, which was subsequently named Baker’s German’s Sweet Chocolate. Fast-forward to June 13, 1957. The Dallas Morning Star published the recipe for the cake, invented and submitted by a reader identified as Mrs. George Clay, according to What’s Cooking America.
Fact: Marla Gibbs continued to work as a flight attendant for two years after being cast on a hit TV show
Prior to taking her place on the stoop of 227, Marla Gibbs played the housekeeper Florence on The Jeffersons (a spin-off of All in the Family).

Fact: The Philippines consists of 7,641 islands
The Philippines is an archipelago, which means it’s made up of a group of islands—7,641 islands, to be exact. That figure does not include the thousands of sandbars and other landforms that emerge during low tide.
Fact: A one-way trip on the Trans-Siberian Railway involves crossing 3,901 bridges

Fact: The Golden Girls was supposed to have a different theme song
That’s right: Instead of Andrew Gold’s iconic “Thank You for Being a Friend,” the show’s producers wanted to use Bette Midler’s song “Friends,” according to Jim Colucci, author of the book Golden Girls Forever: An Unauthorized Look Behind the Lanai. But the rights to the Divine Miss M’s song were too expensive, and the rest is sitcom history.
Fact: There’s enough gold inside Earth to coat the planet
Turns out, there’s quite a bit of gold on—or, really, in—our planet: 99 percent of the precious metal can be found in the Earth’s core, Discover Magazine reports. How much is there? Enough to coat the entire surface of the Earth in 1.5 feet of gold.
Fact: Cleveland was once the country’s fifth-largest city
Data from the 1920 U.S. census indicates that Cleveland, Ohio, was one of the most heavily populated cities in the country, behind only Detroit, Philadelphia, Chicago, and New York City. Today, these are the largest cities in the world.
Fact: Human beings can use only a small fraction of Earth’s water
In school, we were taught that most (specifically, 71 percent) of the planet’s surface is covered in water. While that’s true, humans can use only 0.007 percent of that water, according to National Geographic. That’s because only about 2.5 percent of Earth’s water is fresh water, and only 1 percent of that is accessible. The rest makes up glaciers and snowfields. By the way, have you ever wondering why we can “smell” snow?
Fact: Wally Amos is responsible for making more than just cookies famous
You may be familiar with Wally “Famous” Amos, thanks to his packaged chocolate chip cookies.

Fact: It takes a drop of water 90 days to travel the entire Mississippi River
Spanning 2,340 miles, the Mississippi River is the third-largest watershed in the world. That’s one long stretch of water. So long, in fact, that it takes one drop of water approximately 90 days to travel its entire length.
Fact: People once ate arsenic to improve their skin
You’ve probably heard about how a lot of the Victorians’ favorite cosmetics were riddled with arsenic, but it gets worse.

Check out these other things to wonder about that you likely never thought of before.
Fact: Professional athletes used to perform in vaudeville during the off-season
Before today’s big-league salaries, professional baseball and football players often had to take on jobs during the off-season, The Atlantic reports.

Frankly, many of the athletes had no business being on stage, but it’s not like it was against the rules.
Fact: The first time the word “period” was used on TV in reference to menstruation was 1985
It came via a line in a Tampax commercial: “Feeling cleaner is more comfortable. It can actually change the way you feel about your period.” And the actor who made pop culture history was Courtney Cox of Friends fame.
Fact: McDonald’s once made bubblegum-flavored broccoli
This crazy McDonald’s fact will have your taste buds crawling. Unsurprisingly, the attempt to get kids to eat healthier didn’t go over well with the child testers, who were “confused by the taste.”
Fact: Some fungi create zombies, then control their minds
The tropical fungus Ophiocordyceps infects ants’ central nervous systems. Once it has been in an insect’s body for nine days, it has complete control over the host’s movements. According to National Geographic, it forces the ant to climb trees, then convulse and fall into the cool, moist soil below, where fungi thrive. Once there, the fungus waits until exactly solar noon to force the ant to bite a leaf and wait for death.
Fact: The first oranges weren’t orange
The original oranges from Southeast Asia were a tangerine-pomelo hybrid, and they were actually green. In fact, oranges in warmer regions, such as Vietnam and Thailand, still stay green through maturity. Speaking of which, ever wonder which “orange” came first: the color or the fruit? We found out!
Fact: There’s only one letter that doesn’t appear in any U.S. state name

Yes, 421! Some examples: sneesl (to start raining or snowing); feefle (to swirl); and flinkdrinkin (a light snow).
Fact: Samsung tests phone durability with a butt-shaped robot

Fact: The Windy City nickname has nothing to do with Chicago’s weather
If you live in Chicago, you might already know this random fact, but we’re betting most other people don’t. Chicago’s nickname was coined by 19th-century journalists who were referring to the fact that its residents were “windbags” and “full of hot air.”
Fact: Peanuts aren’t technically nuts
They’re legumes. According to Merriam-Webster, a nut is only a nut if it’s “a hard-shelled dry fruit or seed with a separable rind or shell and interior kernel.” That means walnuts, almonds, cashews, and pistachios aren’t nuts either. They’re seeds.
Fact: Armadillo shells are bulletproof
In fact, one Texas man was hospitalized when a bullet he shot at an armadillo ricocheted off the animal and hit him in the jaw. That’s a totally true animal tidbit. These animal “facts,” however, are false.

The chemicals reduce the surface tension of plain water so it’s easier to spread and better soaks into objects, which is why it’s known as “wet water.”
Fact: The longest English word is 189,819 letters long
We won’t spell it out here, but the full name for the protein nicknamed titin would take three and a half hours to say out loud. While this is, by far, the longest word in English, the longest word in the Oxford English Dictionary has 45 letters, and the longest made-up word has just 28. Just a few more interesting facts for your next cocktail party!

But then the mother gathers each egg—which is about the size of a grain of rice—and weaves them into braids, allowing her to keep an eye on everyone at the same time.
Fact: Cats have fewer toes on their back paws
Like most four-legged mammals, cats have five toes on the front, but their back paws only have four toes. Scientists think the four-toed back paws might help them run faster. Here are more purr-fectly fascinating facts about cats.
Fact: Kleenex tissues were originally intended for gas masks
When there was a cotton shortage during World War I, Kimberly-Clark developed a thin, flat cotton substitute that the army tried to use as a filter in gas masks.

When turkeys are scared or excited—like when the males see a female they’re interested in—the pale skin on their head and neck turns bright red, blue, or white. The flap of skin over their beaks, called a snood, also reddens. By the way, this is why the president pardons a turkey every Thanksgiving.
Fact: Most Disney characters wear gloves to keep animation simple
Walt Disney might have been the first to put gloves on his characters, as seen in 1929’s The Opry House, starring Mickey Mouse. In addition to being easier to animate, there’s another reason for the gloves: “We didn’t want him to have mouse hands because he was supposed to be more human,” Disney told his biographer in 1957.
Fact: The man with the world’s deepest voice can make sounds humans can’t hear
The man, Tim Storms, can’t even hear the note, which is eight octaves below the lowest G on a piano—but elephants can.

It started as a school project for Bob Heft’s junior-year history class in 1958, and it only earned a B-minus.

Eisenhower called to say the design was approved, Heft’s teacher changed his grade to an A.
Fact: Cows don’t have upper front teeth
They do have molars on top, in the back of their mouths, but where you’d expect upper incisors, cows, sheep, and goats have a thick layer of tissue called a dental pad. They use that with their bottom teeth to pull out grass.

Most of it is covered in gravel, though it also contains mountains and oases. And here’s another geography fact that everyone gets wrong: It isn’t the world’s largest desert. Antarctica is.
Fact: Bananas grow upside down
Or technically, we peel them upside down. Naturally, they grow outward from their stems, but that means their bottoms actually face the sky. As they get bigger, the fruits turn toward the sun, forming that distinctive curve.
Fact: There were active volcanoes on the moon when dinosaurs were alive
Most of the volcanoes probably stopped erupting about a billion years ago, but NASA findings have suggested there might still have been active lava flow 100 million years ago, when dinosaurs were still roaming.
Fact: Dogs sniff good smells with their left nostril
Dogs normally start sniffing with their right nostril, then keep it there if the smell could signal danger, but they’ll shift to the left side for something pleasant, like food or a mating partner. If you’re a dog lover, you’ll want to know these other fascinating facts about dogs.
Fact: Avocados were named after reproductive organs
You’ll never look at avocados the same way again. Indigenous people of Mexico and Central America used the Nahuatl word āhuacatl to mean both “testicles” and “avocado.” The fruits were originally marketed as “alligator pears” in the United States until the current name stuck.
Fact: T. S. Eliot wore green makeup
No one is sure why the poet dusted his face with green powder, though some guess he was just trying to look more interesting.

Fact: Mercedes invented a car controlled by a joystick
The joystick in the 1966 Mercedes F200 showcase car controlled speed and direction, replacing both the steering wheel and pedals. The car could also sense which side the driver was sitting in, so someone could control it from the passenger seat.

Fact: Europeans were scared of eating tomatoes when they were introduced
Scholars think Hernán Cortés brought the seeds in 1519 with the intent of the fruits being used ornamentally in gardens. By the 1700s, aristocrats started eating tomatoes, but they were convinced the fruits were poisonous because people would die after eating them. In reality, the acidity from the tomatoes brought out the lead in their pewter plates, and they actually died of lead poisoning.
Fact: Humans aren’t the only animals that dream
Studies have indicated rats dream about getting to food or running through mazes. Most mammals go through REM sleep, the cycle in which dreams occur, so scientists think there’s a good chance they all dream.
Fact: The inventor of the microwave appliance received only $2 for his discovery
Percy Spencer was working as a researcher for American Appliance Company (now Raytheon) when he noticed that a radar set using electromagnetic waves melted the candy bar in his pocket.

Fact: Paint used to be stored in pig bladders
The bladder would be sealed with a string and then pricked to get the paint out. This option wasn’t the best because it would often break open. American painter John G. Rand was the innovator who, in the 19th century, made paint tubes from tin and screw caps.
Fact: Humans have jumped farther than horses in the Olympics
The Olympic world record for the longest human long jump is greater than the world record for longest horse long jump.

It would have taken a year to recreate what was deleted, but luckily another employee had a backup of the entire film on her laptop at home.
Fact: Steve Jobs, Steve Wozniak, and Ron Wayne started Apple Inc. on April Fools’ Day
The three technology innovators signed the documents to form the Apple Computer Company on April 1, 1976. But the company was not fully incorporated until January 3, 1977. Thirty years later, the company was renamed Apple Inc. and is no joke. In 2018, Apple became the country’s first trillion-dollar company. Of course, computers have come a long way over the years—here’s what computers looked like the decade you were born.

Fact: Your brain synapses shrink while you sleep
Researchers at the University of Wisconsin-Madison Center for Sleep and Consciousness studied mice to observe what happens to their brains while they sleep. Dr. Chiara Cirelli and Dr. Giulio Tononi found an 18 percent decrease in the size of synapses after a few hours of sleep. Don’t worry, though—this nighttime brain shrinkage actually helps your cognitive abilities. Speaking of your mind, did you know that these brain myths aren’t true?
Fact: A waffle iron inspired one of the first pairs of Nikes
Bill Bowerman was a track and field coach in the 1950s who didn’t like how running shoes were made. He first created the Cortez shoe but wanted a sneaker that was even lighter and could be worn on a variety of surfaces. During a waffle breakfast with his wife in 1970, he came up with the idea of using the waffle texture on the soles of running shoes. Waffle-soled shoes made their big debut in the 1972 U.S. Olympic track and field trials in Eugene, Oregon.
Fact: Boars wash their food
National Geographic reported that at Basel Zoo in Switzerland, zookeepers watched adult and juvenile wild boars pick up sandy apples and bring them to a nearby creek in their environment to wash before eating.

People have been playing baseball since the mid-19th century. In the early days, umpires would officiate the games while reclining in a rocking chair located 20 feet behind home plate. By 1878, the National League also declared that home teams must pay umpires $5 per game.
Fact: The first commercial passenger flight lasted only 23 minutes
In 1914, Abram Pheil paid $400 (which would be $8,500 today) for a 23-minute plane ride. The Florida flight flew between Saint Petersburg and Tampa, where only 21 miles of water separate the cities. Pheil, a former mayor of Saint Petersburg, and the pilot, Tony Jannus, were the only passengers. This momentous flight paved the way for air travel as we know it. Speaking of which, here are some airplane facts you’ve always been curious about.
Fact: The world’s first novel ends mid-sentence
The Tale of Genji, written by Murasaki Shikibu in the 11th century, is considered the world’s first novel. After reading 54 intricately crafted chapters, the reader is stopped abruptly mid-sentence. One translator believes the work is complete as is, but another says we’re missing a few more pages of the story.

Fact: A woman called the police when her ice cream didn’t have enough sprinkles
The West Midlands police in England released a recording of a woman who called 999 (the U.K. version of 911) because there were “bits on one side and none on the other,” she says in the recording. She was even more upset when the ice cream truck man did not want to give her money back.
Fact: Uncle Ben’s rice was air-dropped to World War II troops
German chemist Erich Huzenlaub invented a process of parboiling rice to keep more nutrients in the rice and lessen the cooking time. The “Huzenlaub Process” had another unexpected benefit: It stopped bug infestations. The quick-cook, bug-free rice was a big advantage during World War II, and converted rice (as it was then known) was air-dropped to American and British troops. After the war, the company rebranded itself and became Uncle Ben’s Original Converted Brand Rice, named after one of the company’s best rice suppliers. The product hit grocery store shelves in 1947.
Fact: The British Empire was the largest empire in world history

If you love these interesting facts, test your knowledge with another 100 history trivia questions.
Fact: South American river turtles talk in their eggs
Turtles don’t have vocal cords, and their ears are internal, so scientists believed that turtles were deaf and didn’t communicate through sounds. But research has found that turtles actually communicate at an extremely low frequency that sounds like “clicks, clucks, and hoots” that can only be heard through a hydrophone (a microphone used underwater). These sounds even come from the egg before the turtle hatches. Researchers hypothesize that this helps all the turtle siblings hatch at once.
Fact: Penicillin was first called “mold juice”
In 1928, bacteriologist Alexander Fleming left a petri dish in his lab while he was on vacation—only to return and find that some liquid around the mold had killed the bacteria in the dish. This became the world’s first antibiotic, but before naming it penicillin, he called it “mold juice.” Here are more accidental discoveries that changed the world.
Fact: The first stroller was engineered to be pulled by a goat (or animal of similar size)
William Kent, a landscape architect, invented the first stroller for the third Duke of Devonshire in 1733. But upper-class parents were hardly expected to put effort into transporting their children around, so Kent designed his model to be pulled by a small animal, like a goat.
Fact: May 20, 1873, is the “birthday” of blue jeans
According to the Levi Strauss company, this was the day that Levi Strauss and Jacob Davis, the innovators behind the sturdy blue jeans we all love, got a patent on the process of adding metal rivets to men’s denim work pants. The pants were called waist overalls until 1960, when baby boomers began calling them jeans. And FYI, this is why blue is the most popular denim color.
Fact: 170-year-old bottles of champagne were found at the bottom of the Baltic Sea
The bottles of bubbly are believed to have been traveling from Germany to Russia during the 1800s when they sank to the bottom of the sea, according to New Scientist. It turns out that the bottom of the sea, where temperatures are between two and four degrees Celsius, is a great place for wine aging. Wine experts sampled the champagne and described it as “sometimes cheesy” with “animal notes” and elements of “wet hair.” Mmm.
Fact: The MGM lion roar is trademarked
At the start of any movie made by the Metro-Goldwyn-Mayer studio, the iconic lion roars at the audience. While MGM has gone through several iterations of lion mascots, the sound of the roar is always the same. The company trademarked the “sound mark” with the United States Patent and Trademark Office in the 1980s. Believe it or not, these famous phrases are also trademarked.
Fact: Neil Armstrong’s hair was sold in 2004 for $3,000
The lucky buyer, John Reznikoff, holds the Guinness World Record for the largest collection of hair from historical celebrities, reports NBC. But Armstrong’s lawyers threatened to sue Marx Sizemore, the not-so-lucky barber who cut the former astronaut’s hair; they said he violated an Ohio law that protects the rights of famous people. Sizemore said he wouldn’t pay, and Reznikoff said he wouldn’t give back the hair but that he’d donate $3,000 to charity.
Fact: Irish bars used to be closed on Saint Patrick’s Day
You might associate Saint Patrick’s Day with wearing green and drinking so much you think you actually see leprechauns. But until 1961, there were laws in Ireland that banned bars from opening on March 17. Since the holiday falls during the period of Lent in the heavily Catholic country, the idea of binge-drinking seemed a bit immoral.
Fact: Nikola Tesla hated pearls
The electrical engineer paved the way for current system generators and motors; the way electricity gets transmitted and converted to mechanical power is thanks to his inventions. But despite his patience with scientific experimentation, he apparently had no tolerance for pearls. When his secretary wore pearl jewelry one day, he made her go home.
Fact: Thomas Edison is the reason you love cat videos
After inventing the kinetograph in 1892, Edison was able to record and watch moving images for the first time. He filmed short clips in his studio, some of which feature famous people like Annie Oakley and Buffalo Bill. But the real stars of these early videos are the Boxing Cats—adorable cats that he recorded in a boxing ring circa 1894. If you like cat videos, you’ll also appreciate these cat memes.
Fact: Brad Pitt suffered an ironic injury on a film set
In Troy, based on Homer’s Illiad, Pitt plays the brave (and buff) Greek hero Achilles. Legend has it that Achilles could not be defeated unless hit in his heel. (It’s where we get the term “Achilles’ heel,” meaning a vulnerable point.) While filming an epic battle scene, Pitt ironically hurt his Achilles tendon—an injury that set back the film’s production by two months.
Fact: Pregnancy tests date back to 1350 B.C.E.
According to a document written on ancient papyrus, Egyptian women urinated on wheat and barley seeds to determine if they were pregnant or not, reports the Office of History in the National Institutes of Health. If wheat grew, it predicted a female baby. If barley grew, it predicted a male baby. The woman was not pregnant if nothing grew. Experimenting with this seed theory in 1963 proved it was accurate 70 percent of the time.
Fact: Martin Luther King Jr. got a C in public speaking
The world remembers Dr. King as a leader of the Civil Rights Movement, and people often quote his “I Have a Dream” speech, which he delivered in 1963. Yet more than a decade before that legendary speech, while attending Crozer Theological Seminary in Pennsylvania, he earned a C in public speaking during his first and second term. Check out these other ironic “failures” of hugely successful people.
Fact: Bees can make colored honey
In France, there’s a biogas plant that manages waste from a Mars chocolate factory, where M&Ms are made. Beekeepers nearby noticed that their bees were making “unnatural shades of green and blue” honey. A spokesperson from the British Beekeepers’ Association theorized that the bees eating the sugary M&M waste caused the colored honey. Speaking of colors, find out what is the world’s ugliest color next.
Fact: Bananas glow blue under black lights
To the everyday eye under normal conditions, ripe bananas appear yellow due to organic pigments called carotenoids. When bananas ripen, chlorophyll begins to break down. This pigment is the element that makes bananas glow, or fluoresce, under UV lights and appear blue. While this is definitely among the most interesting facts about bananas, we have another one that will make you want to eat a banana every day.
Fact: Wimbledon tennis balls are kept at 68 degrees Fahrenheit
The temperature of a tennis ball affects how it bounces. At warmer temperatures, the gas molecules inside the ball expand, making the ball bounce higher. Lower temperatures cause the molecules to shrink and the ball to bounce lower. To make sure the best tennis balls are used, Wimbledon goes through more than 50,000 tennis balls each year.
Fact: Adult cats are lactose intolerant
Like some humans, adult cats don’t have enough of the lactase enzyme to digest lactose from milk, causing them to vomit, have diarrhea, or get gassy. Cats only have enough of that enzyme when they’re born and during the early years of their lives.
Fact: Albert Einstein’s eyeballs are in New York City
They were given to Henry Abrams and preserved in a safety deposit box. Abrams was Einstein’s eye doctor. He received the eyeballs from Thomas Harvey, the man who performed the autopsy on Einstein and illegally took the scientist’s brain for himself.
Fact: The Pope can’t be an organ donor
Pope Benedict XVI was issued an organ donor card in 1970. Once he ascended to the papacy in 2005, the card was invalid, reports the Telegraph. According to the Vatican, the Pope’s entire body must be buried intact because his body belongs to the universal Catholic Church.
Fact: A one-armed player scored the winning goal in the first World Cup
Héctor Castro, who accidentally cut off his right forearm while using an electric saw as a teenager, played on the Uruguay soccer team during the first-ever World Cup in 1930. In the last game between Uruguay and Argentina, Castro scored the winning goal in the last minute of the game. The final score was 4–2, making Uruguay the first country to win the World Cup title.
Fact: The world’s oldest toy is a stick
Think of how versatile a stick is. You can use it to play fetch with your dog, swing it as a bat, or use your imagination to turn it into a lightsaber. That’s why, in 2008, the National Toy Hall of Fame inducted the stick into its collection of amazing toys as, very possibly, the oldest toy ever. But wait—we aren’t done with interesting facts just yet! Next, check out these happy facts that will make your day a little better.
