Or for the more ballistically inclined with access to a three-pase electricity supply, you could build a coilgun.
I built one once. Threw the switch. It worked for about half a second before the current melted the insulation off the cables I'd used. You can imagine what happened then, especially since I'd wedged just about every breaker closed in order to get enough current to the thing. And Oh-boy did I get enough current...
Fortunately I had the good sense not to hold it at the time.

Heh, Jacob's Ladder kit's have been a mainstay for many electronics shops down here for years. I've never really contemplated making one though.....
I have however considered building the contents of a certain book, no it's not one of the other certain books of which I may've skimmed over the chapters on pyrotechnics & locksmithing, laughed at the volume on atomics and winced at the encyclopedic volumes on gunsmithing.

BTW: I wonder how much thrust you can get out of one of those home-made jam jar jets.

Not much, ramp it up too much the jar explodes. Theo Gray, PopSci's resident mad & the Element guy, covered them in his http://www.amazon.com/foo/dp/1579127916/. The jar will also explode from thermal shock too.
