Balloon Science Experiment
Engage kids in learning about chemistry and physics through a fun balloon science experiment using baking soda and vinegar.
Ingredients
Materials for the Experiment
- 2 tablespoons Baking soda Adjust the amount for desired effect.
- 1/2 cup Vinegar Use flavored vinegar for a different experience.
- various Balloons Different sizes can affect results.
- Funnel Help with filling the balloon.
- 1 Empty plastic bottle A soda bottle works well.
- optional Food coloring Add for a visually striking reaction.
- Measuring spoons For accurate measurement of baking soda.
Instructions
Preparation
- Gather all the materials listed to have everything ready before starting.
Experiment Steps
- Fill the balloon with about 2 tablespoons of baking soda using a funnel.
- Pour about 1/2 cup of vinegar into the empty plastic bottle. Add food coloring if desired.
- Carefully stretch the open end of the balloon over the mouth of the bottle, keeping the baking soda in the balloon.
- When ready, lift the balloon upright to let the baking soda fall into the vinegar.
- Observe as the balloon inflates from the reaction creating bubbles and gas.
- Discuss the reaction: baking soda (base) interacts with vinegar (acid).
Notes
Experiment with different amounts of baking soda and vinegar for varied reactions. Use various balloon sizes for more fun.
