I got a water balloon, put it in a plastic bag and put it in the chest freezer. I also took a normal water balloon and put it in a bucket. I also took another water balloon and left it in the sun. I did it to see what would happen.
I colour coded the water balloons: pink is normal temperature, orange was hot, and blue was cold.
The orange one EXPLODED and stuck to the chair I'm guessing because all I found was the water balloon stuck to the chair. The blue one was extremely interesting, the outer shell was all ice, the inside was water and it popped in my hand ,but it didn't fire water everywhere, it was a solid ball of ice with water in the middle. The pink one was just a normal water balloon.
If you're watching this please enjoy.
