One contributor to YouTube has compiled some party-stunts that use basic science. Very neat.
I've always like the fork-balancing one, but the the two burning matches stunt was new to me!
Plus, the one about rotating the foot... human brains are so interesting, aren't they?
He later uploaded a follow-up with ten more clever acts. Worth a look. I'm sure many people have smashed a glass trying the feather stunt. My fav: the coin/liquid/matches/glass (it works by creating a vacuum).
Thanks "Quirkology" (a.k.a. Richard Wiseman)!
