Nope, not at all, thanks for the condescending attitude though. What I might have missed was what Nick said, gas canisters for propane tanks, which so far as I'm concerned is perfectly legitimate misunderstanding.
That said, most propane tanks gas cylinders have releases to allow for safe de-pressurization when they are under heat or contents under pressure. So in that way, this still calls into question whether this should really be called a ""bomb"". "
