10 Random Never Heard Facts

1 | Competitive art used to be in the Olympics.

Between 1912 and 1948, the Olympic Games awarded medals in sculpture, music, painting, and architecture, according to Smithsonian magazine. After a heated debate in the post-war years, the competitions were scrapped. John Copley of Britain won one of the final medals: At 73, he would be the oldest medalist in Olympic history if his silver, awarded for his 1948 engraving Polo Players, were still counted.

2 | A chef's hat has exactly 100 pleats.

Bon Appétit magazine brings us this tasty tidbit. A chef's tall hat (officially known as a "toque") is traditionally made with 100 pleats, meant to represent the 100 ways to cook an egg.

3 | "OMG" usage can be traced back to 1917.

One of the earliest uses—perhaps the earliest use—of "OMG" appeared in a letter to the then-member of Parliament, as The Atlantic reports. In 1917, British Navy Admiral John Arbuthnot Fisher wrote to Winston Churchill about rumors of new titles that would soon be bestowed. "I hear that a new order of Knighthood is on the tapis," he wrote. "O.M.G. (Oh! My God!)—Shower it on the Admiralty!" OMG, indeed.

4 | The majority of your brain is fat.

You can literally call someone a fathead, but it's still unkind: According to Psychology Today, 60 percent of human brain matter is made of fat.

5 | Too much water can kill you.

Drinking too much water can be deadly. When guzzling a lot of liquid, you can suffer from water intoxication or hyponatremia, which occurs after an obscene amount of water is consumed, often during endurance events when participants are also losing sodium through their sweat. There have been many notable cases, including the 2002 Boston Marathon competitor Cynthia Lucero, who died from overhydration.

6 | The hottest temperature ever recorded on Earth was 2 billion degrees kelvin.

To give you a sense of how hot that is: The interior of our sun is only about 15 million degrees kelvin. Researchers at Sandia National Laboratories produced the record-breaking temperature in their lab using a superheated gas, equal to about 3.6 billion degrees Fahrenheit, which is… significantly warmer than any temperature your oven could reach.

7 | You might be drinking water that is older than the solar system.

As the The New York Times reports, water on our planet may have originated from ice specks floating in a cosmic cloud 4.6 billion years ago. Not impressed? It follows that "the same liquid we drink and that fills the oceans may be millions of years older than the solar system itself." Something to keep in mind while you're staying hydrated!

8 | The moon is (slowly) slowing the Earth's rotation.

Every one hundred years, the moon adds approximately 1.4 milliseconds to a day. While this may be minuscule, it does add up: When dinosaurs roamed the planet, days were 23 hours long, according to NASA.

9 | Hot water freezes faster than cold water.

Crazy, right? A number of explanations have been suggested for "the Mpemba effect," including one that posits warm containers conduct heat more efficiently, and another that suggests warm water evaporates faster.

10 | Giant squids have the largest eyes of any animal on Earth.

If you're not sufficiently scared of giant squids, consider that their eyes are 11 inches across. That makes them the largest known eyes in the animal kingdom.
