The kids and I are on a mission to make 1 fun science project every Friday all summer long. This last week we decided to try our hands at Homemade Bouncy Balls. I originally saw these on Pinterest and thought I would give learning how to make bouncy balls a shot.
PS. You can follow me on Pinterest, I am always pinning something fun 🙂
So we got out the supplies…
- 1 Tbsp Borax
- 2/3 Cup Warm Water
- 2 Tbsp White School Glue
- 1 Tbsp Cornstarch
- Food Coloring
These amounts make 1 ball.
Add the borax to the warm water and stir.
In a second container mix cornstarch, glue, and food coloring.
*UPDATE* we have since learned that it works much better to add 1 tbsp of the borax mixture to the glue mixture and stir.
After mixed carefully scoop the glue mix into the borax mix while stirring. Use a fork or other utensil to scoop up the glue mix after stirring. Start to form it into a ball with your hands. It will be moist. I had the best results by drying my hands well with a paper towel, and dabbing the outside of the ball.
Just keep rolling it around in your hands to shape it like a ball. This is when I handed it over the the kids and let them do the rolling.
The more you work with it the firmer it becomes.
The Verdict: Learning how to make bouncy balls is a fun afternoon project. They do bounce and the kids had fun. These are the consistency of a very thick silly putty so they do loose their shape and need to be reformed. I also suggest keeping them in a ziploc so they don’t dry out completely and crumble.
