As a former pyromaniac I can assure you that a party balloon filled with hydrogen (or a "Hindenburg Bomb" as we called them) is a pretty underwhelming thing. It goes up in a whoosh, not a bang , not a billowing ball of flame, and the screw-around factor just isn't there. Like, what to you do with it besides let it go whoosh? The only thing that's dangerous about them is how boring they are. You'll be graduating to more interesting forms of pyromancy (like trying to make a flame thrower out of a punching balloon) in no time.
