5 gal propane tanks don't explode either.
(safe range)
Oxygen tanks, however, do..............
We use to take old propane tack fill them with 2 gallon of gas, then fill them with 80 psi of air. place them in a plowed field, and back off 100 yards and hit them with a 30-06 tracer round. Make sure you don't use a field that hasent been plowed or you will need a fire truck
