Hydrogen! Even more buoyant than helium, and if you get it near a flame, the balloon turns into a fireball. Just one of those would make a party more fun. (Do not let oxygen into the mix, though, or you'll get a lot more than just a fireball if the thing ignites.)
- kragen 16y agoA hydrogen-oxygen mixture in a flexible container like a balloon is unlikely to amplify a deflagration into a detonation. However, either way, the fireball radiates mostly in the ultraviolet. You might want to mix some methane or acetylene or something in there to help it radiate in the less-dangerous visible spectrum.
