Having
previously mixed baking soda and vinegar together to make a bubbly mess, we decided to try to harness that released carbon dioxide to inflate a balloon. We poured baking soda into a bottle, added vinegar, and then quickly put a balloon over the opening of the bottle. Very quickly the balloon started to inflate, much to Jr. scientist A's delight. A fun and repeatable experiment - just a little hard to get the balloon on in time.
