Bursting Balloons

The Junior Science Club investigated how long it took for a balloon to burst when it was held over a flame.  Some of our predictions were longer than what actually happened - the red balloon burst iafter only five seconds!

Then we used a small funnel to pour water into the balloons and we repeated the experiment.  This time we found that the balloon did not burst, even when Mrs Bear held it over the flame for over two minutes.  We found out that the water in the balloon absorbs heat so that the actual skin of the balloon does not get too hot and weak.
