    Baking Soda Balloon Experiment.
    The baking soda balloon experiment is a classic science fair project that is both fun and educational. It is a great way to teach children about the properties of baking soda and vinegar, and how they can be used to create a chemical reaction.
    Materials.
    1 balloon.
    1 teaspoon of baking soda.
    1 cup of vinegar.
    1 funnel.
    A bottle.
    Instructions.
    1. Put the baking soda in the balloon.
    2. Use the funnel to pour the vinegar into the bottle.
    3. Quickly put the balloon on the bottle.
    4. The balloon will start to inflate as the baking soda and vinegar react.
    Explanation.
    The baking soda and vinegar react to create carbon dioxide gas. Carbon dioxide is a gas that takes up space, so it causes the balloon to inflate. The reaction between baking soda and vinegar is a chemical reaction. A chemical reaction is a process in which two or more substances are combined to form a new substance. In this case, the baking soda and vinegar are combined to form carbon dioxide gas.
