Amazing Self-Inflating Balloon

This is a really easy, but fun science experiment that my kids loved. 

In a clear plastic bottle, pour about an inch of vinegar. Pour 1 Tbsp baking soda into a balloon, using a funnel.  Attach the balloon around the mouth of the bottle and dump in the baking soda.  The gas from combining the two will cause the balloon to inflate. 

My kids were amazed and wanted to do it again and again and again.

  1. What a great idea! I can't believe I haven't heard of this experiment. My girls are 12 and 11 and still love doing at home science projects. Although they use Time4Learning science curriculum it is always fun to do your own.

    Thanks for the idea!

  2. Awesome! I'm making a list of simple, fun experiments to do this summer, and I'm adding this one to it! We don't seem to get to these types of experiments during the regular school year! Stopping by from HHH and new follower! Thanks for sharing your experiment!
