Back in the late sixties I used to do this with friends. We threw some water, aluminum foil and draino into one of those large glass 7-up bottles and fasten a baloon on top.
It would fill with Hydrogen. We'd then get a bunch together and launch at night with a flaming string and "pow". Very pretty mini-Hindenburgs.

That's an awesome trick ... I'll have to try that one day.
