2. The Great Wall of China is not the only manmade object you can see from space.
You can see loads of manmade objects from space. In fact, the Great Wall of China is actually NOT easily visible from space.
3. It’s not actually harmful to pick up baby birds and return them to their nests, and it will not cause their mother to reject them.
Birds don’t really have a very powerful sense of smell, and they probably wouldn’t be able to tell if a human handled their babies.
4. Human blood is never blue in your body.
Deoxygenated blood has a dark red, and oxygenated blood has is light red. Blood only appears blue because skin and fat makes it look that way.
5. There are not different areas of the tongue dedicated to different tastes. Every taste can be detected on every part of the tongue.

12. Napoleon Bonaparte was not short.
At a towering 5’7”, he was actually taller than the average man of his time. His nickname, “le Petit Caporal,” (which translates to “The Little Corporal”) was probably a term of affection.
13. The Earth doesn’t revolve around the Sun. It’s actually revolving around the solar system’s center of mass.
The center of mass in the solar system is called the Barycenter. Usually it’s contained within the mass of the sun, but not always. When it’s outside the mass of the sun, the Earth is just orbiting around empty space.
14. Not everyone in Columbus’ time thought the world was flat.

31. Sunflowers don’t track the sun across the sky.
They always face east.
32. The Coriolis effect does not actually make water rotate in different directions while flushing toilets and draining bathtubs.
It is a thing, but it’s too weak to affect draining water. Despite popular belief, hemisphere you’re in doesn’t actually change the direction water drains in.
