The Pintester Takes on Homemade Bouncy Balls

There are two types of people in the world. (Yes, to begin this post, I am going to make a broad, sweeping generalization. Deal.) There are those who get chemistry, and those who don’t. I myself am in the “don’t” category. I consider myself a decently smart person, but chemistry and I have just never gotten along. State changes at the molecular level might as well be magic as far as I’m concerned.

And yet. I thought it would be a good idea to try to make my own polymer bouncy balls using chemistry principles. Hah.

Now, really, the instructions are simple enough. You don’t need to boil anything or use a candy thermometer or anything like that, so I figured it would be pretty safe. The hardest part was locating borax, which I eventually just gave in and ordered from Amazon.

The second hardest part was opening the damn box.

I dissolved my borax as instructed.

And then I even added some industrial grade food coloring one of my readers mailed to me! I was pretty excited about that. (I used green, in case it should happen to spill on my 90’s green counters. Them’s smarts.)

Then I measured out a tablespoon of glue, which takes longer than you might think.

Now here’s where things got a leetle interesting. I had to mix part of the green borax stuff with the glue, and then add cornstarch. And I sort of spilled the cornstarch, so it’s a possibility that I may have added too much. (Do you see now why chemistry and I didn’t get along well?)

mixing balls

I let it sit for a little bit and then stirred it as instructed.

And it did eventually form a ball. A sad, sick, pale green ball, but still, a ball. (I’m really glad that this is the only sad, sick, pale green ball in my life. Just sayin’.)

Then I forgot about it for a minute while I was doing something else and let it sit on the counter and when I came back for it, it wasn’t really a ball anymore. Hrm.

So I did the best I could to re-form it and then I decided that the last test had to be whether it actually bounces or not. See for yourself.

Sooo, yeah, I am going to give this project an F, but if we’re being honest, I got an F in chemistry in school, so the fault is probably my own, somehow.
