Okay...this site is just plain fun. I'm going home and building a film can cannon with my kiddo's tonight.
For those who won't bother to look unless they get a cookie first, it's a web site full of little experiments that you can put together with household stuff that demonstrate various scientific principles (and can be fun to to as well). Launch a plastic film can 20 feet in the air with a cigarrete lighter clicker, 2 wires, and a little squirt of binaca...intrigued?
