Balloon Science Experiment
Engage young minds with this fun balloon science experiment that demonstrates air pressure and chemical reactions using simple household materials.
Ingredients
Materials
- 1 balloon 1 balloon (any color) Use any color for visual appeal.
- 2 tablespoons 2 tablespoons of baking soda
- 1 cup 1 cup of vinegar Any type of vinegar works, such as white or apple cider.
- 1 A plastic bottle or small container This will be used to mix the vinegar and baking soda.
- 1 Funnel (optional) Helps to pour baking soda into the balloon.
- 1 drop Food coloring (optional) For visual interest.
- 1 Safety goggles (optional) For a fun touch and extra safety.
Instructions
Preparation
- Using the funnel, insert it into the neck of the balloon. If you don't have a funnel, stretch the balloon’s neck over the opening of the bottle.
- Pour 2 tablespoons of baking soda into the balloon using the funnel.
Set Up the Vinegar
- Pour 1 cup of vinegar into the plastic bottle. Add food coloring now if desired.
- Carefully place the balloon’s opening over the bottle’s neck without letting any baking soda drop in yet.
Mix and Observe
- Lift the balloon so that the baking soda falls into the vinegar.
- Watch the fizzing and bubbling as a chemical reaction occurs, inflating the balloon.
Discuss the Science
- Explain how the reaction between baking soda and vinegar produces carbon dioxide gas, which inflates the balloon.
Notes
Consider using colored balloons, glitter, or different balloon sizes for more fun. Always supervise young children during the experiment.
