Acetylene has a slightly sharper crack than hydrogen...
I do like the vortex cannon idea.

Garbage bags are famous tags with TAG cavers, toss a little carbide and water in a garbage bag, shake it up and wait for it to inflate. Ignite. Oh what a glorious noise. http://en.wikipedia.org/wiki/Carbide_lamp

meuon, yep, we're going to ramp this up a little bit: I want to play with trash bags rather than just balloons, but I need to find some smaller ones because I've seen video of a full-on black plastic garbage can bag and there are some potential issues with... oh, I don't know, broken windows, that sort of thing.

We have 4H rabbits. I didn't read closely enough before watching the video and was horrified for a minute.

The DHS spent over $17,392 of our tax money analyzing that video for possible terrorist intentions. Do it some more. :)
