WHAT TO DO:
Use a funnel to add 1/4 cup baking soda to the inside of a balloon.
Fill a plastic bottle with approximately 1 cup vinegar.
Attach the balloon to the mouth of the plastic bottle, then lift the balloon upright so the baking soda falls and causes the reaction.

HOW THE EXPERIMENT WORKS:
When you mix baking soda (sodium bicarb) and vinegar (acetic acid), a chemical reaction occurs, producing carbon dioxide gas, which inflates a balloon when trapped inside a container; this is because baking soda is a base and vinegar is an acid, creating an acid-base reaction that releases carbon dioxide gas as a byproduct.

Simply said… The vinegar and the baking soda mix together to make an acid-base reaction. The reaction creates carbon dioxide gas that bubbles up from the mixture. The gas expands up and out of the bottle and inflates the balloon.
