Not really, if you're talking about the green coleman propane cylinders - they don't go boom. That's hollywood. If you shoot them with a rifle they spew, and most of the time don't
ignite. Even igniting them only produces a nice flare. not a boom. Let's just say my misspent youth shot at lots of "interesting" things. Hollywood makes lots of things explode that don't. Generally speaking stuff like propane and gas has to be mixed with air before it'll explode. coming out of a container, even ignited, it just burns. (unless you let the stuff coming out mix with air first before providing a source of ignition - then boom..

Otherwise my turkey fryer would have exploded yesterday - instead of just making quick work of a turkey <img src="/forums/images/graemlins/smile.gif" alt="" />
