On a much smaller scale... I once setup a propane cylinder.. those ones that are thermos bottle size.. it was about 1/3 full yet.. I laid it at an upward angle, facing away from me, with the bottom end exposed.. hit the bottem end ALMOST dead center with a .22 cal rf and the cylinder took off like what a rocket looks like when it takes off and flew in an almost strait line about 20 yards.  cool

Pretty cool!  Amazing how tough the steel tank was...
