We uploaded another version of this video on 11/9 but it had a big mistake in it. So we fixed it. This version is full of 100% real science! Sorry for the error.

In the interest of transparency, if you want to watch that wrong version and see what I was wrong about, here's the link: https://youtu.be/qR9hucj02u0
