Steve Spangler Science: Fireproof Balloon

Balloon and flames don’t mix, unless you add a little water to conduct heat.

Common sense tells you that it’s impossible to boil water in a paper bag, but this classic parlor trick was a favorite of Victorian magicians. The real difficulty in performing this effect is making it look harder than it is! As you might imagine, the secret lies in yet another amazing property of water – its ability to conduct heat. Instead of using a paper bag, this modern day version of the demonstration uses an ordinary balloon, some water, and a candle. It’s a combination that’s guaranteed to make people stand back.
