My kiddos love science projects, and this Expanding Balloon Science Experiment did not disappoint!
Begin by gathering your supplies!
All you need is vinegar, baking soda, a water bottle, a balloon, and a plastic bin to contain the mess: optional – Around here, we don’t mind a little mess.
- Fill 1/3 of the water bottle with vinegar.
- Pour approximately 1 tablespoon of baking soda down in the balloon. (A cup with a spout or a funnel comes in handy here!)
- 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!
I always keep an extra-large bag of baking soda (from Sam’s) and an extra-large jug of vinegar (from Target) on hand. Not only are these ingredients great for science experiments, but I also use a mixture of the two in my laundry as well as when I’m cleaning in the kitchen.
