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!!!
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. :)

That is so cool! That would be fun to do with my second graders!

If you have an explanation why it works, I would love to hear it. Thanks so much!
The contracting molecules form a vacuum:)
Here is a better explanation:

Huge thanks! Remember this from my childhood, but not all the steps. Thanks!
