1. The heads on Easter Island have bodies.

The iconic stone heads protruding from the ground on Easter Island are familiar to most, but many don't realize what lies beneath the surface. In the '10s, archaeologists studying the hundreds of stone statues on the Pacific Island excavated two of the figures, revealing full torsos, which measure as high as 33 feet.

2. The moon has moonquakes.

Just as earth has earthquakes, the moon has—you guessed it—moonquakes. Less common and less intense than the shakes that happen here, moonquakes are believed by U.S. Geological Survey (USGS) scientists to occur due to tidal stresses connected to the distance between the Earth and the moon.

3. Goosebumps are meant to ward off predators.

Why do we get goosebumps? In this physiological reaction, small muscles attached to individual body hairs contract, which leads the hair to stand on end. We inherited this ability from our ancestors in part as a way for our (then) coat of body hair to capture air beneath it and in that way retain heat. But, as George A. Bubenik, a physiologist and professor of zoology at the University of Guelph in Ontario, Canada, explained to Scientific American, it also caused our ancestors to appear bigger than they were, helping to ward off predators when they were frightened or on the defense. With modern humans having less body hair, goosebumps no longer cause us to look that much more intimidating.

4. There's no such thing as "pear cider."

"Wait," you're probably thinking, "I had pear cider last week." Actually, "cider" is an alcoholic beverage made from fermented apples, and only apples. Alcoholic beverages can be made from pears, but that drink is known as "perry." The drink was popular in England for centuries but fell out of favor during the second half of the twentieth century. That turned around in the 1990s when the drink was rebranded as pear cider.

5. Pineapple works as a natural meat tenderizer.

The fruit is packed with the enzyme bromelain, which breaks down protein chains, making it an ideal marinade for meats when you don't have a lot of time. But for the same reason, pineapple does not work for jams or jellies, since the enzyme breaks down gelatin as well. The bromelain is so strong that pineapple processors have to wear protective gloves, otherwise over time the enzyme eats away at the skin on their face and hands, leaving dry skin and small sores.

6. Humans are the only animals that blush.

We are also believed to be the only animal that feels embarrassment—a complicated emotion requiring understanding others' opinions and other factors. Charles Darwin called blushing "the most peculiar and most human of all expressions," while Mark Twain said, "Man is the only animal that blushes. Or needs to."

7. The feeling of getting lost inside a mall is known as the Gruen transfer.

We've all heard how casinos are designed to deliberately disorient visitors, causing them to lose track of time and where exactly they are. But did you know that there's a similar strategy behind the design of shopping malls as well? Officially known as the "Gruen transfer," this phenomenon was named after Austrian architect Victor Gruen, who identified how an intentionally confusing layout could lead to consumers spending more time and money in a shopping venue (though he would later disavow the approach).

8. The wood frog can hold its pee for up to eight months.

Talk about having to go! Wood frogs in Alaska have been known to hold their urine for up to eight months, sticking it out through the region's long winters before relieving themselves once temperatures increase. The urine actually helps keep the animal alive while it hibernates, with special microbes in their gut that recycle the urea (urine's main waste) into nitrogen.

9. The hottest spot on the planet is in Libya.

Specifically, the hottest spot ever recorded on Earth is El Azizia, in Libya, where a temperature of 136 degrees Fahrenheit was recorded on Sept. 13, 1922. While hotter spots have likely occurred in other parts of the planet at other times, this is the most scorching temperature ever formally recorded by a weather station.

10. You lose up to 30 percent of your taste buds during flight.

This might explain why airplane food gets such a bad reputation. The elevation in an airplane can have a detrimental effect on our ability to taste things. According to a 2010 study conducted by Germany's Fraunhofer Institute for Building Physics, the dryness experienced at a high elevation as well as low pressure reduces the sensitivity of a person's taste buds to sweet and salty foods by about 30 percent. Add that dry cabin air affects our ability to smell, and our ability to taste is reduced further.
