Why rule out hydrogen? In small quantities it’s probably not that dangerous, and it’s cheap to manufacture.

- jws 4y agoI just checked out a couple videos of hydrogen filled party balloons being lit. I think it’s safe to say it could be a pants wetting experience and likely ignite paper party decorations.
- simplicio 4y agoYea, Birthday parties mixing small kids, paper decorations, candles and hydrogen balloons seems like a questionable idea.

- mrandish 4y agoSince hydrogen is more buoyant than helium, I wonder if it could be mixed with something which reduces the flame? Either in the gas or in the outer layer of a two layer balloon. It just seems like if a substitute for party balloons is needed then exploring alternate gas mixtures might be low-hanging fruit compared to engineering lightweight yet low-cost vacuum structures.
