The water acts as a heat sink and keeps the balloon from melting. Over time it would pop

The plastics used for balloons are not good conductors of heat, so a candle can causing melting of that plastic from the outside faster than the water within it can cool it down. Eventually, the heat from the candle "melts" its way through, and the surface tension of the balloon is lost and it "pops".

it has to do with the heat distribution... a balloon doesn't melt and pop because the water absorbs and redistributes the heat before there can be a fast enough change in the balloon itself to cause it to melt. If enough heat were applied in a short enough amount of time, eventually the water would boil and the balloon would pop from the water expansion.

For the same reason that a paper cup filled with water doesn't burn when a candle is placed under it. The water absorbs the heat energy thus not allowing the kindling point of the rubber or paper to be reached. Of course it will eventually burst if you persist.

if u put the candle close enough it would pop within a matter of secs.

because water does not expand that much... its not like air.. i stays relitively the same size when its room temp. then heated

because the water is cold and therefore it has to heat up????.....
