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, so the company redeveloped it to be smoother and softer, then marketed Kleenex as facial tissue instead.

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. That’s a totally true animal tidbit.

Vitamin D is both a nutrient we eat and a hormone our bodies make. It is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus; both are critical for building bone. Also, laboratory studies show that vitamin D can reduce cancer cell growth, help control infections and reduce inflammation.
Few foods naturally contain vitamin D, though some foods are fortified with the vitamin.

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.

The tolerable upper intake level (or the maximum amount you can take in a day that likely won’t cause harm) is 2000 mg a day for adults.

Human beings can use only a small fraction of Earth’s water. In school, we were taught that most (specifically, 71 percent) of the planet’s surface is covered in water. While that’s true, humans can use only 0.007 percent of that water, according to National Geographic. That’s because only about 2.5 percent of Earth’s water is fresh water, and only 1 percent of that is accessible. The rest makes up glaciers and snowfields.

Turns out, there’s quite a bit of gold on—or, really, in—our planet: 99 percent of the precious metal can be found in the Earth’s core, Discover Magazine reports. How much is there? Enough to coat the entire surface of the Earth in 1.5 feet of gold.

Vitamin C is an important antioxidant that can help protect the body against various diseases and conditions. It also helps people absorb more iron from plant-based foods and plays a role in immune function, according to the NIH.
