Now there's an idea!TBH, that is what I would expect. Unless you are willing to be right next to it, it won’t explode. As soon as serious injury from proximity is involved, it will be utterly harmless.
what would work really well would be a car inner tube….
EDIT: I actually have an old tire tube I could use (I didn't fully trust it when I bought my divers platform off CL, so I got a new one). I just have to see how I can MacGyver the tire inflator from my air compressor to a LP hose.
