EXPERIMENT: THE BALLOON INFLATER

MATERIALS: A carbonated soft drink in a bottle, a balloon, and a twist tie from a bread or a garbage bag.

WHAT TO DO:

1. Place the balloon over the mouth of the bottle and securing it to the bottle with the twist tie.

2. Have the adult hold the bottle and place their thumb over the mouth of the bottle covered by the balloon.

3. Now shake the bottle for five seconds and release your thumb.

4. The balloon fills with carbon dioxide that was dissolved in the soda pop. That’s why they are called carbonated drinks.  When the carbon dioxide leaves the bottle, the soft drink gets “flat”.
