I just saw an episode of my name is earl. in the episode there is a need to blow open a shed door with a propane tank. the tank was connected to a water hose. the hose was sealed to the propane tank using gum. the propane tank valve was opened and the hose was extended. then a gun is used to ignite the propane tank by shooting a spark into the garden hose. the result was the propane tank exploding and blowing up a storm shed door. is this possible???
