This exciting experiment demonstrates a chemical reaction between baking soda and vinegar that produces carbon dioxide gas, which inflates a balloon. It provides a hands-on approach to understanding reactions, gas expansion, and pressure in a controlled setting, making it ideal for middle school students interested in chemistry.
If I mix baking soda with vinegar, then it will produce enough gas to inflate the balloon.

Pour 1 cup of vinegar into the plastic bottle.
Using a funnel, add 2 tablespoons of baking soda into the balloon.
Carefully stretch the balloon's opening over the bottle's neck without spilling the baking soda.
Lift the balloon to let the baking soda fall into the vinegar.
Observe the reaction and the inflation of the balloon.
Record the time taken for the balloon to inflate.
Discuss the reaction process with your classmates.
Clean up any spills and dispose of materials safely.
