Balloon Baking Soda Experiment
An engaging science activity that showcases a chemical reaction by inflating a balloon using baking soda and vinegar, offering endless fun and learning opportunities for all ages.
Ingredients
For the experiment
- 1 tablespoon Baking soda
- 1/4 cup Vinegar You can substitute with lemon juice.
- 1 Balloon Any shape or size can be used.
- 1 Empty plastic bottle Any container that can securely hold the vinegar will work.
- a few drops Food coloring Optional for visual appeal.
- Funnel Optional but helpful for adding baking soda.
Instructions
Preparation
- Gather all materials in one area for easy access and ensure the balloon is clean and dry.
Fill the Balloon
- Using the funnel, carefully add 1 tablespoon of baking soda into the balloon.
- If you don’t have a funnel, roll the end of the balloon to create a makeshift funnel.
Prepare the Bottle
- Pour 1/4 cup of vinegar into the empty plastic bottle.
- For added fun, mix in a few drops of food coloring with the vinegar.
Combine Ingredients
- Carefully stretch the open end of the balloon over the neck of the bottle, making sure no baking soda falls in yet.
- Hold the balloon upright and gently let the baking soda drop into the vinegar.
Enjoy the Reaction
- Stand back and watch as the reaction produces carbon dioxide gas, inflating the balloon.
- Observe the fizzing and bubbling to experience the excitement of chemical reactions.
Notes
Adult supervision is recommended for young children. You can swap materials (like using lemon juice) and adjust the baking soda amount for different balloon sizes.
