How many do you still believe? How many you don't ?

1 👉Myth: Water conducts electricity
While this is a science myth, it doesn’t mean you should bring your toaster in the bath with you. The reason you shouldn’t swim in a lightning storm doesn’t have to do with the water itself. Pure water is actually an insulator, which means it doesn’t conduct electricity. The danger comes from the minerals and chemicals in it, which are made up of electrically-charged ions. While pure water is theoretically safe around electricity, it’s nearly impossible to find in the real world because even distilled water has ions. Check out these other
2 👉Myth: Blood is blue in your body
A widely shared myth is that blood is blue until it is exposed to air or replenishes its oxygen. Because veins are a greenish-blue, that theory sounds reasonable enough. But the fact is, human blood looks the same in your body as outside: red. That hue is brighter when it’s oxygen-rich, and darker when it needs that oxygen replenished, but it’s red all the same. The tissue covering your veins affects how the light is absorbed and scattered, which is why the blood circulating your body looks blue.
3 👉Myth: Dinosaurs were scaly beasts
The giant, scaly lizards you see in Jurassic Park probably don’t look that close to what actual dinosaurs looked like. While scientists are still debating what the oldest and biggest species were covered with, one thing is for sure: At least some had feathers. Velociraptor arm fossils have bumps that look just like the ones keeping modern birds’ wings in place, and the bones of a Siberian species discovered in 2014 were surrounded by imprints of feathers. While some scientists argue larger species like the Tyrannosaurus rex didn’t need big feathers, others theorize that they had at least some form of light feathering, like how elephants are mammals but don’t have thick fur.
4 👉Myth: Humans only use 10 percent of their brains
The idea of unlocking hidden brain power might make a compelling storyline for a movie, but it simply doesn’t work that way in real life. One fact playing into the myth is that 90 percent of brain cells are “white matter” that help neurons survive, and only ten percent is the “grey matter” of neurons in charge of thinking. But that white matter could never be used for brain power, so claiming 90% of our brain is wasted is like saying you waste peanuts when you throw out the shells. Any fMRI scan will show you that even saying a few words lights up way more than ten percent of your brain. Scientists haven’t uncovered any area of the brain (much less 90% of it!) that doesn’t affect thought, movement, or emotion in some capacity.
