Wow, didn't realize this.  Now I feel bad about mentioning the helium party
kits. Thanks for enlightening me.

I would like to propose an immediate switch to hydrogen for toy balloons.
Advantages are greater lift, nearly limitless supply, either by purchase or
electrolysis, and *much* more fun at parties.  Light the string and step
back...  loads better than singing in squeaky voices!

P.S. Got a match?

P.P.S. I'm not at all serious about the hydrogen.  I don't think it would
be fun or wise to play with large quantities of hydrogen in balloons or
garbage bags.  Especially not near any source of spark or ignition.  You
might never report back to us.
