FACT 1
Luna moths have no mouths. Once they emerge from their cocoon, they have a 7 day lifespan during which they mate and then starve to death. (And yes, it would be a great band name, but there's already a band named The Luna Moth.)
FACT 2
Tears you cry when you're upset actually contain a hormone that's a natural painkiller. Your body releases this hormone (called leucine enkephalin) when you're under stress. So if you ever feel like you need to just sit and have a good cry, your body is just trying to comfort itself.
FACT 3
Hot and cold water sound different when being poured. It's actually noticeable to the human ear if you pay attention. Water changes viscosity (aka its thickness or stickiness) depending on temperature. Long story short, the colder the water, the higher the pitch, whereas pouring something hot like, oh, say..coffee...is going to have a lower, more comforting pitch.
FACT 4
There are animals and plants considered to be "Biologically Immortal." While they can and do die, this is due to injury or disease. They don't really age (at least not in the sense of breaking down) and won't die from old age. Jellyfish and Lobsters are two examples of this.
The smell that grass gives off when it's cut is actually a distress signal. You're basically smelling the grass screaming in pain. Don't tell social media, or we'll have a hashtag about it....
FACT 5
Velociraptors were actually only about the size of a Turkey, not the 6'-7' beasts we've come to know and love from That Dinosaur Park Franchise. Those 'Raptors were actually based on a dinosaur called Utahraptor. So in that scene, in the first movie, with the kid talking about a giant turkey? Actual VELOCIraptors weren't even giant turkeys.
FACT6
Honey, when sealed, does not rot or go bad. It's literally edible thousands of years later. You could eat a 3000 year old jar of honey. Egyptian tombs have been found with jars of still edible honey inside.
FACT7
Sunflowers are sometimes used to clean up nuclear waste and radioactive soil. Sunflowers actually pick up radioactive isotopes, so as they grow, they literally suck the radiation up out of the soil. The flowers and stems are then radioactive, so no word on if they glow at night.
FACT8
Several hundred earthquakes actually occur worldwide on a daily basis; they're just of such a low magnitude (2 or lower) that we often don't notice. Or, you know, in the middle of the ocean.
FACT9
Despite being taught in school we have five senses - sight, touch, smell, taste, and sound - humans really have over 20. For example, Proprioception is the ability to tell where your body parts are in relation to other body parts, even when you can't see them, and Equilibrioception is basically your sense of balance, which allows you to stay upright when doing important things like walking.
FACT10
The weight of the average fluffy, cumulus cloud is a little over a million pounds. Clouds are made up of tiny drops of water dispersed over a large area (much larger than it seems from the ground) and water is very heavy. For context, that's roughly the weight of 100 elephants.
