STEAM POWERED SPUD gun

[robbtoberfest] put together this amazing looking heavy steam powered spud pistol. made of home materials, like a lighter and some copper pipe, this spud gun develops pressure in its bit bitty boiler to expel the projectiles. It seems as though he’s utilizing a cork to supply a seal, so why bother with potatos? At approximately 2 minutes between shots, its not the quickest, but it sure is cool. great task [robbtoberfest].
