a buddy of mine hooked up a hospital tank of compressed gas to his potato gun, which used a sparker from a grill as the igniter. Basically, he filled this big ass PVC chamber up with gas, sparked the little thing and out went a potato at about mach 4.

We then proceeded to make a sawed-off version, which almost killed the neighbor's cat.
