Do a web search on Potato Cannons.  They can be inexpensively  made from PVC
pipe and fueled with propane from a hand torch.  They will throw a 2" diameter
hunk of potato several hundred feet.  They are reasonably safe, easy to make and
one hell of a lot of fun.  Generally quite accurate too.  Proven
technology.......
