Kid craft- Science experiment

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.



Fill your bowl with ice cold water and fill your water bottle with hot water and let it sit for one minute....

....or longer so you have time to explain the whole process to your child! :) Love this picture of these two by the way! 

Then you get all excited for the experiment

Daddy helps by putting the balloon on the bottle like so. 

Then you stick it in the cold water.

And watch what happens!!! 


Then, when you are a child, I mean Audrey, you want to do it by yourself!
I don't even know the technical science explanation right now as to why this works. Something about air and it contracting. Haha! :) Good thing Brandon was home to explain it to her and me! haha!

 I really did have the reason why this balloon did what it did written down on a piece of paper. So, I really was going to explain it to her using the info I had. Don't worry. :)

If you have an explanation why it works, I would love to hear it. Thanks so much!

The contracting molecules form a vacuum:)
