Camels' humps are not for storing water: they're for insulation and food storage.

Yes, You Can Feel When Someone is Looking at You

man staring through fence, astonishing facts

It's called "gaze detection," and it's the sense your brain uses when it feels someone staring at you. Research has shown that certain brain cells fire in response to when someone is staring right at you, but not when the observer's gaze is averted just a few degrees to the left or right of you (which causes different cells to fire instead). We've evolved with this ability in order to sense potential threats, as the direct gaze is a symbol of dominance.

Woman watching tv in bed christmas depression

Watching your favorite shows and movies, re-reading your favorite books, and listening to your favorite music over and over actually has benefits: it puts your mind in a state of ease. As humans, we have a limited pool of mental resources. When we're overwhelmed, we begin to have less self-control and less motivation for the tasks at hand. When you watch a rerun or listen to your favorite tunes, you don't have to exert effort to control what you're thinking, which means your brain can do a quick mental reset.

You'd Need More than 700 Floppy Disks to Equal One Gigabyte of Storage

Floppy Disks, obsolete

But back in the 90s and early 2000, we stored our files on things like floppy disks. And it would take 711 1.44 MB floppy disks to store one gigabyte. That's a whole lot of floppy disks. Thank goodness for the cloud, right?

But the very first one was created in 1990 by a few students at McGill University in Montreal. Apparently, the rudimentary search engine was so popular that at one point it accounted for nearly 50 percent of all of the city's internet traffic. Its inventors named it Archie—like archive but without the "V."

Charlie Chaplin Famous Celebrities Wikimedia Commons/P.D. Jankens

Chaplin was such a success in silent film, that he continued making them for years after "talkies" began to take off in popularity. Part of this was due to the fact that his silent films still made money, and part was due to his own lack of confidence in his skills in the new medium. When he finally did his first talkie, 1940's The Great Dictator, it was a masterpiece that effectively silenced critics.

Founding Father Benjamin Franklin

The man who coined the phrase "a penny saved is a penny earned" lived and died by the mantra. In his will, he left the cities of Boston and Philadelphia each 1,000 pounds sterling (worth about $4,500 at the time), with the caveat that they could not touch it for 200 years. Both followed his wishes and, in 1990, found that those few thousands were worth millions. And for more money secrets, see the 20 Crazy Facts You Never Knew About One Dollar Bills.

The ancient Egyptian calendar was similar to our current one, with 365 days in a year and 12 months. But each was exactly 30 days, leaving five extra days at the end of the year.

politicians assaulting people congress 35th, smart word

In 1928, as former New York Governor Al Smith ran for president against Herbert Hoover in the midst of the debate over whether alcohol should continue to be banned, Smith's campaign figured his anti-prohibition ("wet") stance should be promoted to those frustrated by the restrictions.

77
Aluminum Was Once More Valuable Than Gold

Tin foil

Now that we use it to wrap our food, it might seem hard to believe that in the 19th century, this element was hugely valuable. When it was finally learned how the metal could be extracted, as Slate explains, "people adored Element 13's color and luster, which reminded them of the sparkle of gold and silver—a brand-new precious metal. In fact, aluminum became more precious than gold and silver in the 19th century, because it was harder to obtain. The French government once displayed Fort Knox-like aluminum bars next to the crown jewels, and the minor emperor Napoleon III reserved a prized set of aluminum cutlery for special guests at banquets. (Less favored guests used gold knives and forks.) The United States, to show off its industrial prowess, even capped the Washington monument with a six-pound pyramid of aluminum in 1884." Once innovators figured out how to extract it on an industrial scale, the market came crashing down. But for a while, aluminum was king.

Jim Sheedy, a doctor of vision science and director of the Vision Performance Institute at Oregon's Pacific University, explained to the Wall Street Journal that since pirates were having to move frequently from the bright conditions above deck to the extreme dark below, many "wore a patch over one eye to keep it dark-adapted outside."

We Are Running Out of Helium for Balloons

balloon

Well, it's not quite as dire as you may have heard, but helium is, in fact, a nonrenewable resource and when it is released it escapes earth because of how light it is. That being said, a huge reserve of helium was found just a couple years ago in Tasmania, so we should be alright for a while longer.

"Buttload" Is an Actual Measurement of Wine

Friends Drinking Wine

Some wineries and distilleries still use the antiquated term "butts" to refer to a full cask. It derives from the Medieval French word for boot, and, according to the Macallan distillery, is equivalent to 108 Imperial gallons.

Australia Once Lost a Prime Minister—and Still Hasn't Found Him

Movemember started out down under originally.

That would be Harold Holt, the country's 17th prime minister. He went swimming near Portsea, Victoria, in 1967 and was never heard from again. Of course, he likely drowned, but when a massive search operation failed to recover the body, he was declared in absentia and conspiracy theories remain about what might have really happened to him.

Specifically, there are 80,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (that's 67 zeros) ways to arrange a deck of 52 cards. As Yannay Khaikin explains, "Any time you pick up a well shuffled deck, you are almost certainly holding an arrangement of cards that has never before existed and might not exist again."

Less Time Separates Us from T-Rex Than T-Rex From Stegosaurus

tyrannosaurus rex dinosaur skeleton

If you believe all those dinosaur movies and shows, all the various prehistoric lizards were living together during the same era. Not so fast. As Smithsonian explains, "About 83 million years separated Apatosaurus from Tyrannosaurus and Allosaurus from Triceratops. The so-called Age of Mammals—which began when the non-avian dinosaurs were wiped out—has been going on for about 66 million years. Less time separates us from Tyrannosaurus rex than separated T. rex from Stegosaurus."

A Strawberry Is Not a Berry

Spinach in salad Lower Blood Pressure

You can't judge a fruit by its name. To technically be a berry, a fruit must develop from one flower that has one ovary. Strawberries have flowers with more than one ovary (as do raspberries). And for more amazing facts, see the 40 Random Obscure Facts That Will Make Everyone Think You're a Genius

An Avocado Is a Berry

healthy woman

It's a "single seed berry" to be precise. As UC Riverside's Agriculture and Natural Resources helpfully explains: "There are two main classes of fleshy fruits: drupes and berries. Drupes are characterized by having a fleshy mesocarp but a tough-leathery or bony endocarp. They are said to have 'stones' or 'pits' rather than seeds (example: peaches). Also, a drupe usually has only a single seed. Berries, to the contrary, are characterized by having a fleshy endocarp, as well as mesocarp, and may have more than one seed

Michael Clarke Duncan Was Assigned to Be Notorious B.I.G.'s Bodyguard the Night He Was Killed

michael clarke duncan

Before he was an actor, Duncan was a bodyguard for celebrities, ranging from Will Smith to Jamie Foxx. He had been hired to protect Christopher Wallace—who you may know by his more common name, Notorious B.I.G.—in March 1997. He switched assignments, only to find out later that his almost-client was shot and killed the night he would have protected him. It led Duncan to leave his work as a bodyguard and pursue acting.

92
Croissants Originated in Austria

Croissants

Though we usually think of them as French, these flaky pastries originated as the Austrian kipfel. According to Smithsonian, it originated in 1683 to celebrate Austria's victory over the Ottomans at the siege of Vienna: "The story follows that a baker, up early to make bread, saved the city when he heard the Turks tunneling underneath the city and sounded an alarm. The kipfel's curved shape, said to mimic the crescent moon of the Ottoman flag, then would seem to pay poetic tribute to the indomitable spirit of a city that resisted a powerful invading force."

On Venus, a Day Is Longer Than a Year

the planet venus in space

It takes 243 Earth days for Venus to spin around its axis (that's what denotes a day) but it only takes 225 Earth days for it to travel around the Sun, meaning that a day on the planet lasts a bit longer than a year.

Researchers Are Attempting to Map Every Neural Connection in the Human Brain

Shot of your brain on riddles

The Human Genome Project is well-known, but researchers are currently undertaking the Human Connectome Project, aiming to completely map out the human brain's neural connections in order to better understand its functions and connectivity. "Everyone knows that imaging isn't equivalent to mapping every cell. There's an endless expanse of potential detail that we still wish to know," one of the scientists behind it told National Geographic. "But this [pattern] is a new piece on the chessboard." He pauses. "And it really is a chessboard."

Though one of the few absolute requirements of anyone running for president of the United States is that he or she be a natural born citizen, none of our first seven presidents would have qualified by this rule. It wasn't until Martin Van Buren, born into the newly created country of the United States in 1782 and elected president in 1837, that we had a natural-born president. Interestingly enough, he was also the first president for whom English was not his first language.

It Rains Diamonds on Saturn

stars in space

Too bad it's uninhabitable. When lighting storms strike on Saturn, it turns methane into carbon soot, which hardens as it falls to the ground, first into graphite, then diamonds. The high-value hailstones are, according to one researcher, "big enough to put on a ring, although of course they would be uncut."

101
Clouds Turn Grey Because They Get Thicker

cloudy sky weather affects your mood

Generally, clouds are white and fluffy, and that's because the water particles are spread widely apart, which allows light to pour through. When a cloud is about to pour rain, however, it gathers more water droplets and ice crystals, making it thicker, which prevents light from peeking through. The result is a darker shade of gray.

102
Placing A Ripe Banana Next To Fruits Will Ripen Them

bananas things you're doing wrong

As they ripen, bananas produce ethylene gas, a plant hormone that stimulates ripening. Not all fruits respond (for instance, citruses don't), but for those that do, the gas causes ripening by triggering the genes in plants that regulate growth and decomposition (ETR1 and CTR1); the gas causes these to turn off, which cause other cells to turn on, leading the breakdown of cell walls, conversion of starches to sugars, and the disappearance of acids—all of which we simply call "ripening."

103
Men Are More Likely to be Colorblind than Women

Pick-Up Lines So Bad They Might Just Work

The most common gene for colorblindness is transmitted on the X-chromosome, which women have two of, compared to just one in men. The gene is recessive, so in a female, even if she has the mutated gene, the stronger, dominant X chromosome will "win" out. Conversely, if the male ends up with the non-dominant colorblind gene on his X chromosome, he will be colorblind, because he doesn't have another X chromosome.

Tylenol Can Help Ease Emotional Pain, Too

tylenol murders

Everyone loves acetaminophen for its ability to reduce physical pain, but did you know it can reduce emotional distress too? A study conducted at the University of Florida has shown that the pills regularly used to dim bodily aches and pains also dim activity in brain regions that process social pain. In scarier news, another study also showed a reduction in empathy among regular acetaminophen consumers, as well.

105
Female Dragonflies Sometimes Fake Death to Avoid Having to Mate

dragonfly genius facts

In a process called sexual death feigning, female dragonflies will literally stop mid-air and fall to the ground when an aggressive male dragonfly chases after them to mate. It really works (a majority of the time): biologists have confirmed that 60 percent of the female insects who fake their deaths were able to evade mating-crazed males.

106
Coffee Grounds Are An Amazing Ant Repellant 

side effects coffee grounds ibuprofen

Have kids or pets in the house and don't want pesticides on the counters? Try this trick out: Sprinkle coffee grounds (new or used) in the corners of your cabinets, counters, around pet food dishes, and anywhere else ants might pop up. Soon enough, your ant problems will go away: the ants are repulsed by the smell, and, even if they do eat it, the caffeine exposure will kill them.

107
Yes, The Egg Came Before the Chicken

egg carton

Think of it this way: dinosaurs—ancestors of birds—were born from eggs for a really long time. At some point, a chicken-like avian produced an offspring with some sort of genetic mutation that caused it to cross from chicken-like to just chicken. Since this mutated chicken-like turned chicken creature came from the egg, we can definitively say that the egg came first.

 Shaking Your Head Will Wake Up "Sleeping" Body Parts

people, emotions, stress and health care concept - unhappy african american young woman touching her head and suffering from headache - Image

Paresthesia (the clinical term for when your limbs fall asleep) is caused by your nerves being pinched, which restricts the communication between your nerve endings and the brain, so your brain and nerves can't communicate feeling. If the paresthesia occurs in your arms, hands, and upper body, you can usually wake the appendages up by turning the head side to side, as it's generally the nerves in the neck that become pinched, cutting the nerve communication channels from your upper body to the brain.

Tornadoes Are Invisible

Bad weather and the storm with the wind on the sea. tornado over the ocean

According to the National Severe Storms Lab, a tornado is a narrow, violently rotating column of air that extends from the base of a thunderstorm to the ground. Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust, and debris. You don't see the tornado—you see what the tornado picks up.

The Ovum Egg Is the Largest Human Cell And The Sperm Is the Smallest Cell

uterus model, astonishing facts

The gametes of each sex are on polar opposite ends of the cell-size spectrum, with the female ovum (the egg) being the largest cell in all of human biology and the male sperm being the smallest. The "largest cell" is about one millimeter in size—just visible to the naked eye, at roughly the width of a piece of hair (and that's if you have good eyesight).

111
 The Rich Used to Live on the Ground Floors, not Penthouses

old Trajan Market in rome, ancient rome facts

When the Romans first built apartment homes (called insulae, at about nine to ten stories high), it was the wealthier folks that lived on the ground floors. The higher floors rarely had running water, nor did they have bathrooms. Imagine climbing up and down nine stories, every day, multiple times a day! It wasn't until the elevator came around in the 1800s that penthouses and upper-floor units became status symbols.

112
 Young Eggplants Looks like Eggs

eggplant, improve memory

Baby eggplants really do look just like large dark-colored eggs. And back in the 18th century, when the Europeans first named them, eggplants were more of a yellow color, not purple, so the name was even more fitting. Oh, and while we're on weirdly named produce, the grapefruit (which looks nothing like a grape) gets its name from the way the fruits grow in clusters on the tree, like giant clusters of grapes.

There's High-Speed Internet on the Moon

The Moon Landing Unsolved Mysteries

You can scroll through Instagram, post on Facebook, and even watch Netflix on the moon. Using lasers, NASA was able to establish transmission of data from Earth to the moon and back. The researchers achieved upload speeds of 19.44 megabits per second and download speeds of 622 megabits per second over the 384,633 kilometers between Earth and the moon.

114
Real Diamonds Don't Show Up on an X-Ray Machine

diamond real missing treasure

There's an easy way to find out if your sweetie's a cheapie. Diamonds are made of carbon, which has a very low atomic number (six to eight, depending on grade). The lower the atomic number, the harder it is for an x-ray machine to "read." Most x-ray machines are designed with a photon energy high enough that low atomic-number things—like carbon, or the oxygen in water—are fairly transparent, so that things like the calcium in bones (or the metal in weapons) show up more clearly.

115
Clouds Are Insanely Heavy

blue sky with clouds

The average cumulus (the fluffy ones) cloud weighs 1.1 million pounds. So, at that weight, why don't they just fall out of the sky? Because they're relatively light compared to their surroundings: the cloud may weight a lot, but the mass of the air within the same space is approximately 1.1 billion pounds, making it 1,000 times heavier than the liquid.

116
Evidence Exists That the FBI Urged MLK to Commit Suicide

Martin Luther King Jr Memorial

In 1964, the Federal Bureau of Investigation sent an anonymous letter to Martin Luther King Jr. with a recording of what it claimed were his sexual indiscretions and urging him to step down from his leadership role, decline the Nobel prize and/or commit suicide (yes, opinions vary about what exactly the letter was asking that he do). The plot was exposed in 1971 and has proved a constant embarrassment for the organization ever since.

117
Making Margaritas Can Give You Second-Degree Burns

There's a condition called phytophotodermatitis that you get it if you spend too much time in the sun after handling limes, lemons, or even celery. Such produce items contain a chemical compound called furanocoumarin which, when in contact with exposed skin and sunlight, will cause a phototoxic reaction, resulting in what looks (and feels) like second-degree burns.

118
Idiot, Imbecile, and Moron are Clinical Terms

hospital hallway supplement industry

"Idiot" refers to someone with an IQ between 0 to 20; "imbecile" refers to someone between 21 and 50; and "moron" refers to anyone between 51 and 70. All of these terms were medical terms until October 2010, when S.2781 of the 111th Congress (or "Rosa's Law") mandated that the clinical term for any lower IQ-related issues be referred to as "intellectual disabilities."

119
Nautical Mile Speed Is Measured by "Knots" because They Used Knots to Measure It  

Back in the 17th century, sailors measured the speed of their ship by using a contraption called a "common log," a coil of rope with equally spaced knots attached to a piece of wood. The piece of wood was lowered from the back of the ship and allowed to float behind it free from the coil it was attached on the ship. After a specific time had passed, the line was pulled in and the number of knots between the rope and the ship were counted. The speed would be the resulting number of knots.

And that's because fireworks count as explosives. The U.S. government is the only entity to buy more explosives than the happiest place on Earth. Disney keeps its numbers top secret, but some estimate they spend between $45,000 to $50,000 on explosives per show.

Highly dopaminergic individuals tend to work with the abstract, ideas, and the future, and tend to affiliate as liberals. Lower dopaminergic individuals tend to be content with how things are and tend to affiliate as conservatives.

122
 Silence Helps Rebuild the Brain

southern slang

When patients were exposed to prolonged silence (two hours or more at a time), brain scans revealed new cell growth in the hippocampus. In another study exploring the effects of different types of music on the brain, researchers found that the two-minute pause between the music actually induced more relaxation than any type of music. That's right: silence really is golden.

123
 "Gut Feelings" Have Psychological Merit

Rumbling stomach, man holding his stomach in pain

There are more neurons in your gut lining than there are in your spinal cord (that's so your digestive system can work on its own without needing information from the brain). Those butterflies you get in your stomach when you're overcome with emotion? That's your stomach neuron system reacting.

124
To Scale, Saturn's Rings are Thinner Than Paper

planet Saturn in front of the Milky Way galaxy (3d illustration, elements of this image are furnished by NASA) - Illustration

The inner circle of Saturn's seven rings spans about 180,000 miles in circumference. But the rings are, at most, about 0.6 miles. Let's do some math: at the thickest spot, that amounts to a thickness-to-width ratio of 0.0000033. A standard 8.5-by-11 piece of paper (which is 0.004 inches thick) has a thickness-to-width ratio of 0.00036—or more than a hundred times that of Saturn's rings.

125
Saying "God Bless You" as a Response to Sneezing Came from the Days of the Plague

man sneezing

It became commonplace to say "God bless you" after someone sneezed back in Rome, when the bubonic plague was running rampant through Europe. A common symptom of the plague was sneezing, so the Pope at the time (Pope Gregory I) suggested saying "God bless you" to anyone who sneezed, in the hopes that prayer would save them from the deadly plague.

126
Mice Are Used for Medical Research Because of Logistical Size

Mouse brain {best of 2018}

It's true that their genetic makeup closely resembles humans, but, realistically, chimps would be the better choice. Mice also reproduce much faster than monkeys, so it's easier and faster to watch genetic mutations and toxicology effects over the course of generations, in comparison to other test mammals.

127
Your Stomach Could Dissolve a Razor Blade

shaving razor close up

Stomach acid (hydrochloric acid with a PH rating of 1-2) is strong enough to dissolve razor blades. So, if your stomach is so acidic, how does your body handle it? The truth is that your stomach would essentially eat itself if it didn't generate its own protective lining daily. When your body is unable to produce the sugary and protein-filled mucus lining properly, you experience painful ulcers.

128
There Are More than Three States of Matter

Chemical reaction. Two clear liquids are mixed to produce a yellow precipitate.

Forget the three you learned about in grade school science (solid, liquid, gas). You'll also find super-fluid liquids (liquids with a specific quality of zero viscosity), plasma (a gas made only of ions), and amorphous solids, among others. But most interestingly—and commonly—you'll find colloids: the "in-betweens" that contain two or more forms of matter, like whipped cream, shaving foam, and butter.

129
Polishing Your Shoes Is Like Filling in Potholes

man polishing his shoes, astonishing facts

You're not shining or buffing away uneven spots when polishing shoes—you're just filling in the crevices. When you're polishing a shoe, you're just filling in the teeny-tiny scratches and holes with the shoe wax. So why does it get shiny? The filled-in spots then create an even, uniform surface, which reflects light more evenly.

130
A Sunburn Is Your Skin Cells Committing Mass Suicide

bad beauty products

A sunburn is the result of your body forcing your skin cells to essentially destroy themselves (scientific term: apoptosis, or programmed cell death) in an effort to prevent further damage in the form of skin cancer, which can result from the damaged DNA in the burnt cells.

131
The Brain Itself Feels No Pain

old man with a traumatic brain injury

Though the brain controls the pain you feel throughout the body, the brain itself has absolutely zero pain receptors, according to Allan I. Basbaum, a professor of anatomy at the University of California, San Francisco. That's why craniotomy (brain surgery) can be done with the patient wide awake, which is incredibly useful for surgeons trying to map and locate the specific regions in the brain.

132
Sailors Created the Half-Staff Flag Mourning Tradition

flag at half staff at sunset

The first record of a flag being flown at half-staff for mourning was on a British expedition to Canada in 1612, on which the captain was killed. The crew lowered the flag to make room for the invisible "Flag of Death." This tradition caught on among sailors from across the seven seas and was truly solidified in 1799, when the U.S. Navy ordered all flags to fly at half-mast to mourn the death of George Washington. In 1954, President Eisenhower issued Proclamation 3044, standardizing the requirement for all Federal buildings.

The Mascots of Elmer's Glue and Borden Dairy Are Married

The Borden Company's mascot Elsie, who appeared on its dairy products, eventually acquired an "all-American family" in 1940, including her husband, Elmer. When the company rolled out a new glue in 1947, the fact that it could be used to fix things around the house soon made Elmer, the helpful husband, an obvious mascot.

Lightning Can Strike the Same Place Twice

Lightning over field with a tree

Whether it's within 10 minutes or 10 million years, it's statistically inevitable. (Exhibits A through ZZZ: skyscrapers with antennae, like the Empire State Building or the Willis Tower.) A lightning strike at any location does nothing to change the electrical activity in the storm taking place, which means double strikes are bound to happen.

136
Chocolate Is Scientifically Proven to Make You Happy  

woman eating dark chocolate

There are a few compounds you'll find in your chocolate bar that have been linked to improved mood and even altered brain patterns: tryptophan, an amino acid that helps the brain produce serotonin (the neurotransmitter related to happiness and satisfaction); phenylethylamine, an adrenaline-boosting compound often dubbed the "love" chemical because it stimulates the feeling of falling in love; and theobromine, a compound proven to reduce stress reduction and increase relaxation.

137
Apples Are More Effective at Perking You Up Than Coffee

Apple Cut in Half {New Years Eve Traditions}

An apple has a crisp crunch that wakes you up with a high amount of vitamins, antioxidants, fiber, and phytonutrients. Instead of waking you up with caffeine, the average 12 to 13 grams of natural sugar in the apple is slowly released into the bloodstream, which wakes you up without the jitters that are commonly associated with caffeine. The glucose in the fruit is easily digested by the body to feed cells, providing slow and steady energy, and lasts for the entirety of the digestion process of the apple, rather than the quick spike and crash that results from a cup coffee.

138
Stop Signs Are Eight-Sided For Easy Recognition  

Stop Sign Illegal

The red is for attention, of course, but the shape of the sign was determined by the American Association of State Highway Officials to be the most recognizable. Signs used to not be reflective, so at night it was important for drivers to be able to make out the sign. An octagon is more noticeable than a circle or a square. In addition, the shape is recognizable for traffic traveling in any direction, allowing drivers to be more fully aware of the driving landscape.

Grandparents Who Babysit Live Longer

grandparent and grandchild in the woods

Grandparents who actively babysit and spend time with their grandchildren are proven to live longer. Taking care of kids keeps them physically and mentally active, and also helps to relieve stress. The feeling of being "needed" also plays a role for motherly and fatherly figures. And it's beneficial for the kids, too! Spending time with nana and poppy provides emotional support and stability in the home.

140
Diet Drinks Get You Drunker, Faster  

2018 was worse than 2017

When the body consumes alcohol and a sugary mixer, the sugars act the same way as food would by delaying the stomach's emptying and absorption of alcohol. There are no (or very little) sugars in diet drinks for the stomach to digest, so there's virtually no buffer of time between alcohol consumption and alcohol intoxication. Studies have shown an 18 percent increase in intoxication for those who drank diet mixed drinks compared to those who drank sugary mixed drinks.

You Can Spot a Liar by How they Answer Questions

Woman Talking with Boss at Bar

When you're asking questions to someone you think may be lying, pay attention not to what they say, but to how they answer. Truth-tellers tend to elaborate on answers with more detail the more you ask; liars will tend to stick with the same basic answers, repeating their responses over and over (and over and over) until you just drop the subject.

You Can Stop Crying and Wake Yourself Up with Your Eyelashes

It's an age-old ballerina trick from when stage makeup would irritate the eyes, but you can use it in your day-to-day: to stop yourself from tearing up, look upward and to the left. In addition, if you wake up feeling groggy, you can instantly perk yourself up by lightly brushing your lower lashes with your fingertip. Try it tomorrow morning!

 Pringles' Aren't Potato Chips

Potato chip cans

Pringles are hyperbolic paraboloids that are actually only 40 percent potato. They're made up of rice, wheat, corn, and potato flakes, then pressed into a super-thin sheet and cut by a machine. The cuts then move to a mold, which presses them into their signature shape, and then they're dropped into oil. That's why, on the can, you can read, in small font, "potato crisps" (not "chips").

145
Water-Repellant Clothes Work by Using Surface Tension

Feet of child in yellow rubber boots jumping over a puddle in the rain - Image

Water-repellent clothes are coated with a chemical compound called DWR (durable water repellent), which work by increasing the contact angle (the surface tension) created by water when it touches the fabric. By increasing the angle, a "spiky" surface is formed on the textile, making the water turn into tiny droplets when they make contact with it, so that the water rolls off. If and when the angle is flat (a low contact angle), the water droplets are flatter, so they spread out instead of rolling off.

A Pig Was Once Tried and Executed for Murder

Pig brain crazy news 2018

In 1386, a particularly nasty pig was tried for the murder of a child in Falaise, Normandy, France. Those trying the hog determined it was guilty and sentenced it to be "mangled and maimed in the head and forelegs, and then to be hanged." It was even dressed in a man's clothes as it was trotted into the public square and hanged.

The Most Unlucky Number is 42

powerball winning numbers

In the digital world, at least, 42 is the most unlucky number for a fairly surprising reason. (It's also the last number in the unlucky lottery numbers from LOST.) There's a malicious zip file out there titled 42.zip, aptly named the "zip bomb." It's a scant 42 kilobytes in size, but once unzipped, it expands to 4.5 petabytes (or, for perspective, 4.5 million gigabytes), crashing any system it's opened on. And for more astonishing numerical truths, here are 40 Facts About Numbers That Will Make You Feel Like a Mathematical Genius.
