There is an egg drop competition. If you egg survives, you get points for mass*time. The lowest score gets extra credit. So...Assume you have a helium balloon. The mass of a helium balloon is negative. The time it takes to fall will be close to infinite. Therefore the score will be negative infinity = extra credit. It works, right? :D
You know you're an AP student if...
you think studying is fun.
you constantly find yourself saying "we had homework?"
everything you know about sex, you learned in english class.
If you try to fail, and succeed, which have you done?
