We love science experiments, and when the set up is quick and easy, we are even more likely to enjoy them! Kids love this balloon science project and are happy to repeat it. For us, it was a springboard for a Bubbly Brew, which I will post in a couple days.
Here's The Quick and Easy Preschool Science Balloon Experiment:
Simple Supplies:
- balloon (I like the 12-inch balloons best)
- water bottle (or soda bottle)
- vinegar
- baking soda
- 1-ply bathroom tissue or paper towel (we create this by tearing a paper towel in half)
- a pan to catch everything
Easy How-To:
1- Set the bottle in the pan.
2- If you haven't mixed vinegar and baking soda before, do this in the pan or in a separate bowl. Your children should know that vinegar and baking soda will react.
2- Fill the bottle 1/3 - 1/2 full of vinegar.
3- Place about 2 tablespoons of baking soda in the tissue and wrap it up. Ask what your children think will happen if you add the baking soda and place the balloon on top of the bottle.
4- Squish the baking soda inside the bottle and quickly add the balloon. Watch the excitement!
5- Ask your children what they would like to test next, and help them do it!
Background:
During this science experiment, the vinegar and baking soda react, producing carbon dioxide. The balloon is filled with carbon dioxide. Try a variation on this science project by blowing up another balloon and comparing which balloon is heavier!
I may share at any of these parties!

Great experiment!
So glad you joined me for the Monday Kid Corner party. If you haven’t linked up today, we’re live at www.mondaykidcorner.blogspot.com.

Put the baking soda IN the balloon using a funnel. Carefully attach balloon when ready 'stand up' the balloon so soda falls into the bottle.
My 3 year old thought it was fun. HOWEVER! Putting the tissue with the powder in the bottle was nearly impossible. I resorted to just pouring the baking soda into the bottle. The balloon blew up 1/2 way.
