Make a Gas Balloon
by Jeanette Cain
MATERIALS NEEDED:
1. Balloon
2. Baking soda
3. Soft drink bottle
4. Funnel
5. Pitcher
6. Vinegar
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 place. This explosion often releases a deadly, hot gas cloud.
Place the funnel in the top of the bottle. Add some baking soda. (The funnel needs to be dry or the baking soda will stick to it.) Using the funnel, pour vinegar into the bottle.
This part requires steady, but quick hands: remove the funnel and quickly slip the balloon over the bottle's top. By now, the soda and vinegar are fizzing because they are giving off gas bubbles.
Your balloon begins to inflate due to the pressure (force) of the gas in the bottle; the more gas, the more the balloon inflates. CAUTION: Don't pop the balloon!
