When Chemistry Goes Wrong

We've been having a lot of fun mixing things up lately. But this did not go well. I followed these instructions to make a polymer bouncing ball. I followed the instructions very carefully. But hey, maybe I did something wrong. Because that picture didn't even remotely resemble what we got. 


The website said if we used clear glue, we would get translucent balls. But the corn starch made them opaque.

They were sticky and weird feeling but eventually the stickiness went away as we kneaded it. But it never had the smooth surface of a regular bouncy ball. But it did bounce. 

This was the general reaction to the weird balls.

Our complete failure to make Gak was more amusing and was also caused by my misreading the directions. We will try this one again.
