Fact: Some fungi create zombies, then control their minds
The tropical fungus Ophiocordyceps infects ants’ central nervous systems. By the time the fungi been in the insect bodies for nine days, they have complete control over the host’s movements.

Fact: Samsung tests phone durability with a butt-shaped robot
Do these interesting facts have you rethinking everything? People stash their phones in their back pockets all the time, which is why Samsung created a robot that is shaped like a butt—and yes, even wears jeans—to “sit” on their phones to make sure they can take the pressure.
Fact: The “Windy City” name has nothing to do with Chicago weather
Was this one of the random facts you already knew? 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.

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. The war ended before scientists perfected the material for gas masks, so the company redeveloped it to be smoother and softer, then marketed Kleenex as facial tissue instead.

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 Disney opted for 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 current American flag was designed by a high school student
It started as a school project for Bob Heft’s junior-year history class, and it only earned a B- in 1958. His design had 50 stars even though Alaska and Hawaii weren’t states yet. Heft figured the two would earn statehood soon and showed the government his design. After President Dwight D. Eisenhower called to say his design was approved, Heft’s teacher changed his grade to an A.
Fact: Cows don’t have upper front teeth
They do have molars in the top back of their mouths though. 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.

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 poison because people would die after eating them. In reality, the acidity from the tomatoes brought out lead in their pewter plates, so they’d died of lead poisoning.

Fact: Paint used to be stored in pig bladders
Pig bladders were used in the 19th century to store an artist’s paint. The bladder would be sealed with a string and then pricked to get the paint out.

The waffle sole shoe made their appearance in the 1972 U.S. Olympic track and field trials in Eugene.
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.

He flew between St. Petersburg, Florida and Tampa, Florida, where only 21 miles of water separate the cities. Pheil, a former mayor of St. Petersburg, and the pilot, Tony Jannus, were the only passengers. This momentous flight paved the way for air travel as we know it.

Fact: Uncle Ben’s rice was airdropped 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, too: 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 airdropped to American and British troops. After the war, the company rebranded to Uncle Ben’s Original Converted Brand Rice, named after one of the company’s best rice suppliers, and the product hit the shelves in 1947.
Fact: The British Empire was the largest empire in world history
According to the World Atlas, an empire “is a group of nations or people that are under the rule of a powerful government or an emperor of a territory usually larger than a kingdom.” The British Empire was most powerful in the 1920s when it ruled over 23 percent of the world’s population. That equates to about 13 million square miles.
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. However, 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”
Alexander Fleming was one of those quirky scientists who accidentally made a scientific breakthrough. In 1928, the bacteriologist 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.”
Fact: The first stroller was pulled by a goat
This is one of the many interesting facts that had us scratching our head. Or a dog or a miniature horse, but not by parents.

By the mid 18th century, strollers were still pretty unstable, but they had handles so parents, not animals, could pull the baby behind them.
Fact: May 20, 1873, is the “birthday” of blue jeans
According to the Levi Strauss website, 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 for the first time in history.

Fact: 170-year-old bottles of champagne were found at the bottom of the Baltic Sea
The bottles of bubbly are estimated to have been traveling from Germany to Russia during the 1800s when they sank to the bottom of the sea, says New Scientist. Turns out that the bottom of the sea, where temps are between two and four degrees Celsius, is a great place for wine aging. Oenologists, people who study wine and winemaking, sampled the champagne and described it as, “sometimes cheesy,” with “animal notes,” and that it had elements of “wet hair.”
Fact: The MGM lion roar is trademarked
At the start of any movie made by the Metro-Goldwyn-Mayer studio, there’s the iconic lion that roars at the audience.

The company trademarked the “sound mark” with the United States Patent and Trademark Office in the ’80s.
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. The not-so-lucky barber Marx Sizemore, who cut Armstrong’s hair, received threats of being sued by Armstrong’s lawyers who 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 St. Patrick’s Day
You might associate St. Patrick’s Day with wearing green and drinking so much you think you actually see leprechauns.

Fact: Pregnancy tests date back to 1350 BCE
Based on an ancient papyrus document, Egyptian women urinated on wheat and barley seeds to determine if they were pregnant or not, according to the Office of History in the National Institutes of Health.

Fact: Wimbledon tennis balls are kept at 68 degrees Fahrenheit
The temperature of tennis balls affects how the ball bounces. At warmer temperatures, the gas molecules inside the ball expand making the ball bounce higher. A tennis ball at lower temperatures causes the molecules to shrink and the ball bounces lower. To make sure the best tennis balls are used, Wimbledon goes through over 50,000 tennis balls.
Fact: Adult cats are lactose intolerant
Feeding your cat milk could be making them sick. 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 life.

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. Its adaptability, along with how old sticks are, is among the reasons why the National Toy Hall of Fame inducted the stick into its collection as possibly the oldest toy ever.
