An experiment in chemistry
Find two balloons, a candle, matches and some water. Inflate a balloon and hold it above a candle light to demonstrate that balloons blow up if subjected to high temperature. Then pour some water into the second balloon, tie it and hold it above the candle. The balloon filled with water won’t be affected by temperature. Explain to your child that this happens because the water that fills the balloon absorbs the heat. That’s why the balloon doesn’t burn or blow up.
