Expanding Balloon Science Experiment

My kiddos love science projects, and this Expanding Balloon Science Experiment did not disappoint!

Supplies needed:

vinegar baking soda water bottle balloon plastic bin

Step-by-Step Instructions:

Step 1: Fill 1/3 of the water bottle with vinegar.

Step 2: Pour approximately 1 tablespoon of baking soda down in the balloon.

Step 3: Attach the balloon to the water bottle and watch the balloon expand!

Don’t be afraid to let your kids try this experiment multiple times – each time adjusting the amount(s) of baking soda and vinegar (more or less)!

That’s part of the fun of this experiment!
