We all learn the same things in science as we make our way through school. We discover that mixing baking soda and vinegar creates a volcano, how to make carnations change color and that mitochondria are the powerhouse of the cell. While these are all important things to know, we’re not going to talk about them here.
Instead, we will explore all the dark and dangerous corners of science that your high school teacher didn’t want or wasn’t allowed to teach you about.
There’s plenty of weird science worth knowing about. Here are 20 of our favorites.
1. Human Bodies Glow — We Just Can’t See It
They tell you to shine bright like a diamond, but that’s challenging when the human body doesn’t actually shine — or does it? Scientists found that people have their own kind of bioluminescence. It’s just not visible to the naked eye.
2. Your Stomach Can Dissolve Razor Blades
While we don’t condone the consumption of razor blades, the human body is capable of great feats. One study found that the acid in the human stomach is more than sufficient to dissolve a razor blade after a couple of hours.
3. Clouds Are Heavy
Clouds look light and fluffy when you see them hovering in the air, but they’re anything but. The big cumulus clouds you might see on a sunny afternoon can weigh upwards of a million pounds.
4. Your Eyes Are Better Than Any Camera
Pictures on the latest cellphones can capture 20 or 30 megapixels, but that’s nothing compared to what you can see with the human eye. If your eye were a camera, it would be capable of capturing a whopping 576 megapixels.
5. You Lose Bones as You Grow
Everyone knows that you have 206 bones in your body, but you don’t start out that way. When you’re born, you have around 300 different bones in your tiny infant body. As you grow, many of these merge to create the skeleton you know and love as an adult.
6. J and Q Are Missing
There are 118 elements on the periodic table. However, you’ll never find one J or Q on the table. That might change in the future, but for now, we apologize to all those Johns, Jessicas and Quentins that can’t spell their name with elements.
7. We Eat Less Than You Think
We’ve got many different options when we head to the grocery store, but when you start breaking things down into their base components, its a lot less complicated than you think. About 75% of the food we eat today comes from 12 plant species and five animal species.
8. Gas Is Not Smelly
We know what to do if we smell gas, but in its natural state, it’s odorless. To prevent explosive accidents, companies add mercaptan to the natural gas to give it an unpleasant odor that lets you know when there’s a leak.
9. Oxygen Isn’t Colorless
We don’t think of oxygen as anything but an invisible component in the air we breathe, but unlike many other gases on the periodic table, oxygen isn’t colorless. If you cool O2 down until it becomes a liquid or freezes solid, you’ll see that it’s an incredibly pale blue.
10. It’s Raining … Diamonds?
On Earth, we think of diamonds as rare or exclusive items, but on other planets, they might be as common as an afternoon thunderstorm. On some of the gas giants in our solar system, astronomers suspect it might rain diamonds deep in the atmosphere.
11. You’re More Bacteria Than Human
Your body contains trillions of cells and even more bacteria. In the average body, bacteria and other microorganisms outnumber your regular cells 10 to one. They’re so small, though that they make up less than 3% of your body’s overall mass.
12. Most of the Universe Is Invisible
When we look up at the night sky, we can see hundreds of thousands of stars. We can view even more with the aid of telescopes, but we’re only looking at a fraction of what is out there. Roughly 80% of the universe is made up of dark matter, which is currently unobservable with existing technology.
13. You Can Trap a Laser
We’ve all seen how water will refract light, but you can also use that to your advantage if you want to trap a laser. Just aim a laser pointer at a stream of water, and it will end up trapped within the stream, following it as it curves toward the ground.
14. Phobias Can Be Genetic
Do you have something that you’re afraid of that doesn’t make sense? These irrational phobias may have a basis in genetics. A 2013 study found that your phobias might be genetic, appearing due to your ancestors’ experiences.
15. Rats Laugh When You Tickle Them
Some people don’t mind being tickled. Other people hate it with a fiery passion. A 2016 study found that rats enjoy it — and they let out tiny high-pitched rat giggles when tickled.
16. Camels Can Change Their Blood
One of the most popular camel myths is that they store water in their hump, allowing them to traverse long distances without stopping to drink. While this isn’t true, studies have found that they can dehydrate without changing their blood viscosity, allowing them to function normally in high heat.
17. Komodo Dragons Don’t Need No Man
Komodo dragons are incredibly solitary creatures — to the point of reproducing without the need for a mate. A komodo dragon in Tennessee gave birth to three offspring through a process known as parthenogenesis. Less than 0.1% of vertebrates are capable of doing the same.
18. Don’t Get Stung by This Jellyfish
No one likes getting stung by a jellyfish, but they don’t usually make you feel like the world is ending — unless you get stung by the Irukandji in Australian waters. The sting of this little box jellyfish triggers something known as Irukandji syndrome, which causes you to feel a growing sense of dread that can become so dramatic people have begged doctors to put them out of their misery.
19. Cats Are Into Physics
Cats are usually into catnip and laser pointers, but one in the 1970s started to dabble in physics. Jack H. Hetherington was writing a paper in 1975 when he realized he had written the entire thing in the plural despite being the only author. Rather than going back to edit the whole piece, he simply added a second author — F.D.C. Willard, otherwise known as his cat, Chester. Chester has co-authored papers for decades.
20. Honey Never Goes Bad
Honey is a super tasty treat that you can add to tea or your favorite pastry. Unlike sugar or other sweeteners, you don’t ever have to worry about it going bad. Its sugar concentration is so high that it is naturally antibacterial. Jars of honey that are more than 5,000 years old are shockingly still safe to eat.
