Science Fun ~ Mysteriously Inflating Balloon Experiment

When I saw this experiment on The Artful Parent I knew that I wanted to try it with Emily and Juliette.  They both love balloons and I thought that this would be a fun way to see them getting inflated.  I made a few changes to how the experiment went based on the comments to Jean’s post.

First, I got everything ready…all I would show them was the balloon.  They were all so excited to see what would happen.  I filled the water bottle with about 3 tablespoons of vinegar and then I used a funnel to fill the balloon with about 1 tablespoon of baking soda.  I put the balloon on top of the bottle being careful not to let the baking soda mix with the vinegar.

After each child had their balloon set up I counted to 3 and let them hold up the balloon so that the baking soda would mix with the vinegar.

It was funny to see the different shapes that it made!
