02/28/2005: "Match Stick Rockets"
Stumbled on this website... I found something like this a couple years ago when I was in Engineering schoo.. Basically its a bit of tinfoil wrapped around the head of a paper match with a bent paper clip holder. When done properly it'll shoot about 8 feet and make a cool foosh sound. They kept us ammused for a couple months... definately geeky cool.
