Parties would be more interesting if the balloons were filled with hydrogen gas anyway.

- rkomorn 6mo agoReminds me of a demo my college physics professor did in our first class (presumably to get our attention). He had two floating balloons, one about twice as big as the other. Pointed a blowtorch at the smaller one and it (of course) popped. "That one was filled with helium. Now, there's only one gas less dense than helium..." and right as I thought to myself "he's not gonna do what I think he's gonna do", he pointed the blowtorch at the other balloon which exploded into a much larger (and much louder) fireball. Attention captured, for sure.
