10 Facts That Sound Fake But Are Actually Totally True

Did you know you can hear the difference between hot and cold water?

1. You can hear the difference between hot and cold water when it’s poured.

If that sounds fake to you, just give this video a listen. The key is that the viscosity of water decreases as the temperature increases, so the difference you’re hearing is largely due to the change in viscosity.

2. Sharks existed before trees.

The earliest undisputed shark fossils date back 420 million years. The first trees appeared on Earth during the Devonian period, and the oldest estimates place them at about 408 million years ago.

3. Blue eyes are newer to the human race than pottery.

A 2008 study by a team at the University of Copehagen traced the gene for blue eyes back to one common ancestor, who mostly likely lived about 10,000 years ago. By contrast, the oldest pieces of pottery unearthed in China date back as far as 20,000 years ago.

4. Charlie Chaplin and 50 Cent were alive at the same time.

Though they’re thought of as living in very different times, Chaplin died on Dec. 25, 1977… Roughly two and a half years after Curtis Jackson, aka 50 Cent, was born.

6. One 17-inch pizza is more pizza than two 12-inch pizzas.

Let’s do some pizza math, shall we? The area of a circle is π*r², so a 17-inch pizza would have an area of about 227 square inches (3.14*8.5²=226.865). A 12-inch pizza has only about 113 square inches, which makes two of them just about a square inch smaller than one 17-inch. So just order the large.

7. The state of Michigan is slightly bigger than Great Britain.

The area of Great Britain is 94,226 square miles, including land and water area. Comparatively, the land and water area of Michigan is 96,716 square miles. However, if you only consider land area, Britain has Michigan beat by a little over 36,000 square miles.

8. All peacocks are male.

There’s no such thing as a female peacock…because they’re called peahens. If you’re referring to a group of the two, you’d just call them peafowl.

9. More people are killed each year by cows than by sharks.

The CDC found 21 incidents of cow-related deaths in a four-state area over a five-year period, which comes out to just about four deaths per year just in that area. Meanwhile, there’s only about one death per year attributed to shark attacks.

10. The 2% margin of error the Chinese government aims for when taking their population census is larger than the entire population of Australia.

The population of China, as of 2016, was 1.378 billion. Two percent of that is still a whopping 27.57 million people, which is larger than the population of Australia, which was a little over24 million in 2016.
