Anybody ever build a potato cannon ? :)

I made one from pvc and lawn sprinkler valve and use compressed air instead of hairspray, etc. Works well and out shoots a buddy of mines hair spray fired one. Got the idea from a web search.
 
We built one as a science project when I was in middle school, but we had it shoot tennis balls. Those things shot out a good 100 yards!

My brother and I have a tripod mounted oxyacetylene powered potato cannon in the garage.
