We did another science experiment with Audrey the other day. We were lucky and Brandon came home from work just in time to do this experiment with us! Thank goodness too because he was able to explain how it works to Audrey a lot better than I can! Brandon loves science and is so good at it. We had a lot of fun doing this with him. My favorite part was when he was explaining to Audrey the whole process and why the balloon expanded like it did. Audrey was just sitting there listening to him. It was the cutest moment!
Here's what you need: A water bottle, balloon, and cold water.
