Balloon by Jeanette Cain 2. Baking soda 3. Soft drink bottle
When a volcano erupts, it gives off gases. This experiment shows
how the buildup of gas pressure can inflate a balloon. CAUTION:
You will need an adult to help. There is also the possibility
that putting too much gas-making mixture in the bottle can cause
the balloon to explode! This is what happens inside a volcano:
gas pressure builds up causing an ernormous explosion to take
