DocKom's Surf Shop: Experiments

Hey, try the fun and exciting "Carbon Dioxide Balloon" experiment. Go ahead and give it a try!

You will need:

A round balloon

A plastic soda bottle

2-3 teaspoons of baking soda

1/4 cup of vinegar

A small funnel

Here's what you do:
1. Place the baking soda in the balloon using the funnel.
2. Pour the vinegar into the bottle.
3. Place the balloon opening over the bottle opening.
4. Lift the balloon up so that the baking soda falls into the bottle.
5. Swirl the bottle a little to mix the contents
6. Watch what happens!

Here's what's happening:
A chemical reaction takes place between the vinegar and the baking soda. It creates the gas carbon dioxide, which caused the balloon to fill up. Carbon dioxide is what we breathe out when we exhale. Plants breathe in carbon dioxide, like we breathe oxygen.
