In physics class the prof was talking about freefall and he says if you're in an elevator that free falls then you die. But I was thinking on my own, and I'm basically the smartest person I know, and I did out the equations and got that you can survive by jumping at the last second. It's really surprising but it's actually true. But if you mistime by even a little you're fucked. How should I tell the professor? I wanna embarrass him because he's such a huge dick.
