Fire Resistant Water Balloon – Sick Science! #122
Find out how this is possible at http://www.stevespanglerscience.com/experiment/fire-water-balloon
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. 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.

you can also drink water before blowing it up so you wont need to pour water into it..
I believe this is the same principle as a radiator in a car. since the liquid in the balloon is under pressure, it can take the heat better and dissipate it, thusly causing the balloon to not pop? I may or may not be wrong, but if someone has another theory, reply to this.
The water is absorbing the energy giving off by the flame in this case the heat. Instead of the heat overwhelming the balloon and therefore it exploding, the water is kinda 'tanking' the heat.
Yep
I thought it was because the water has a high specific heat allowing it to absorb a lot of energy without changing temperature too dramatically.
been there, seen that
Cool : D
because water has high specific heat , thus it uses heat energy for boiling and balloon doesn't get any heat energy
because the water is a conductor of heat. So the water inside the balloon is absorbing the heat from the flame and protecting the balloon from popping.
