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.
