The homemade bouncy ball is simply a thick mixture that is created through a chemical reaction with the borax and the glue. Not adding any additional water makes the recipe thick and bouncy.

Throw the borax bouncy ball onto the floor and it really bounces! Kids will love seeing how different mixtures of chemical reactions can create different final results.

See the difference between this recipe, the classic borax slime recipe, the fluffy slime recipe, and the laundry starch slime recipe. 

You can learn a lot when making a homemade bouncy ball! Here are just a few STEM elements that go along with this lesson:

STEM Questions to Ask

TURN SLIME INTO A BALL

What happens if you add more glue (borax, water, cornstarch)?

Which recipe bounces the highest?

How much higher does the bounciest recipe bounce than the least bouncy recipe?

What makes the ball bounce?

Will the ball bounce on carpet (cement, wood, a table, a counter, etc)?

Will the ball hold its shape over time?

How to Make Your Own Borax Bouncy Ball

For each ball, you’ll need to make two separate solutions in two cups. In cup one, mix 2 tablespoons of school glue, 1 tablespoon of cornstarch, and food coloring (we did pink for Valentine’s Day).

This Valentine's Day, make these bouncy balls using just borax, glue, and corn starch! Kids will be amazed at how easy it is to make a homemade bouncy ball!

In cup two, mix 4 tablespoons of warm water and 1 teaspoon of borax powder. This is the recipe we started with.

This Valentine's Day, make these bouncy balls using just borax, glue, and corn starch! Kids will be amazed at how easy it is to make a homemade bouncy ball!

Mix each cup together, then slowly add the borax water to the glue mixture. It will turn into slime, then harden even further into a pliable mixture like play dough.

This Valentine's Day, make these bouncy balls using just borax, glue, and corn starch! Kids will be amazed at how easy it is to make a homemade bouncy ball!

Work the ball between your fingers until it is no longer sticky and you can roll it into a ball.

Bounce it on a surface and see what happens!
