Hydrogen alone just makes a soft pop; as you say, for a bang it needs to be mixed with oxygen prior to ignition.

>you'd be amazed at the bang a litter bag filled with a hyd/ox mixture can produce if set alight.

Try a large garbage bag with oxyacetylene mix (do not try this at home).

I guess - never having tried the party balloon trick myself - that such a small amount of hydrogen will mix well enough with the surrounding air as the balloon pops to create a (modest, at least) bang as the mix ignites, but this is just conjecture.

Maybe I'll have to do some empi research one of these days - we do have a few bottles of oxygen and acetylene in the workshop at my current employer.

Hey ho, time for an engineer to pay our welders a visit.
