Make a Bouncing Polymer Ball by Anne Marie Helmenstine, Ph.D.
Who doesn't love a bouncy ball? As a kid, and even into adulthood, I love these things. When I saw that I could make my own!! Save money!! Impress my son!! Game on, let's do it. I couldn't wait. How much fun this would be as something that my son and I could do to give as gifts.
Wrong.
This recipe for making a Polymer Bouncing Ball was one big flopping disappointment. As far as the picture, in the upper left, is concerned, mine didn't come any where near to looking like that!
Let's just say, there is always room for error when working with an experiment. So, that said, if anyone else tried this and had success, please comment and let me know. Especially, if you were able to replicate the picture at the top. Because, the picture, below this paragraph, is what mine looked like. We made several different colors. None of them turned out like the picture above advertises them to.
As you can see, from the picture below, they could be stretched. They did not hold their shape, at all.
Despite the failure to replicate the picture, my son did love this, and he did have fun, and they do bounce. They just have to be thrown, with a good amount of force. The "ball" will bounce once, but because it flattens upon impact, it will not bounce again. My son played with these all day, and for days, until, they ultimately dried up and became useless.
I left some out to dry, thinking maybe they just needed to harden up a bit. This rendered them into a hard, ball of nothing. We put the dried up ones, in File 13. The others, were kept in a zip lock baggy to keep them from drying out so quickly.
