It’s time for another Pinterest Tuesday!
Even though there is less than 2 hours left of Tuesday. Today the boys and I created our own bouncy balls! I figured this would be an exciting project to do because of the amount of measuring and mixing involved. My oldest is learning about measuring, and my youngest has always loved watching and helping me cook. So this was definitely something they wanted to do. And what kid doesn’t like a bouncy ball?
Since we do many activities like this one (homemade slime, mostly) I already had a box of borax on hand. It’s actually the same box I’ve had since my 5 year old was 1. It still mostly full too! All the other ingredients are usually found around the house. Especially in a homeschooler’s house.
What you’ll need:
- 1/2 cup warm water
- 1 Tbsp borax
- 2 Tbsp white (liquid) glue
- 1 Tbsp cornstarch
- Food coloring
- Optional: Plastic disposable cups and plastic forks. The clean up was so much easier because I could just throw everything away instead of scrubbing cups/bowls.
What we did:
I definitely did not make this “instagram worthy”. No high definition, posed pictures here. I am actually surprised I remembered to take any pictures at all. I could have taken over a bit more and made the balls perfectly round and smooth, but I really let my boys do most of the work. This is for them, after all. I made one whole recipe for each boy.
In the first cup, we mixed the warm water and the borax. In the second cup, we mixed the glue, cornstarch, and food coloring. Once everything was mixed thoroughly, we poured the borax mixture into the glue mixture and stirred. It hardened almost instantly.
After a few seconds of stirring, I pulled out the glob with the fork and squeezed it in my hand a few times. Just like the slime you can make with borax, you need to knead it a bit. Once the ingredients seemed to bond together I let my boys roll and squish them until they formed into a ball they approved of. Only once the glob mixture was too slimy to bond together. So I dunked it back into the water a few times and that did the trick.
Our four balls are a lot larger than I was expecting. You could easily make two out of each. Next time I will half the recipe to make more but smaller bouncy balls.
Oh, and YES! They actually do bounce! We stored ours in plastic bags. I will come back in a week or two and update here how they hold up. Another Pinterest Tuesday win!
Edit: They did not hold up very well. They are basically slime, so they do flatten out. It was very hard to actually roll them back out, but that may have been because ours were so big to begin with. Also, if any of the bouncy balls are touching while stored, the colors will bleed into one another.
