Keep reading for the best bouncy ball recipe, step-by-step instructions, and pro tips to make your bouncy ball bounce higher!
Why Do Homemade Bouncy Balls Work? (The Science Behind It)
The reason why a homemade bouncy ball bounces is all thanks to polymerization—a chemical reaction that occurs when you mix glue and borax. The glue contains polyvinyl acetate (PVA), a liquid polymer, which turns into a solid, rubbery texture when combined with borax.
This reaction creates a polymer cross-linking effect, making the ball stretchy, firm, and bouncy—just like the ones you buy at the store!
Want to turn this into a fun science experiment? Try adjusting the glue-to-borax ratio and see how it affects the bounce!
What You’ll Need (DIY Bouncy Ball Ingredients)
To make a super bouncy ball, you only need three simple ingredients:
- ½ cup warm water
- 1 tablespoon borax powder
- 1 to 2 tablespoons clear Elmer’s glue (or glitter glue for a fun effect!)
Optional: Add food coloring, glow-in-the-dark paint, or glitter to customize your ball.
How to Make a Bouncy Ball (Step-by-Step Guide)
Step1: Make the Borax Solution
Pour ½ cup of warm water into a bowl.
Stir in 1 tablespoon of borax powder until fully dissolved.
Let the solution cool slightly before the next step.
Step2: Add the Glue
Slowly pour 1 to 2 tablespoons of glue into the borax solution.
If using glitter or colored glue, now is the time to get creative!
Step3: Form the Bouncy Ball
As soon as the glue touches the borax, it starts solidifying.
Use your hands to squeeze and shape the mixture into a ball.
If the ball is too sticky, dip it back into the borax solution for a few seconds, then continue shaping.
Step4: Let It Set and Dry
Once your ball is smooth and firm, set it aside for a few hours to dry.
The longer it dries, the bouncier it will become!
Best Tips for Making a High-Bouncing Bouncy Ball
Experiment with different types of glue – Clear glue gives a translucent effect, while glitter glue adds sparkle.
Don’t overwork the mixture – Too much handling can make the ball less bouncy.
Store properly – Keep your bouncy ball in a sealed plastic bag to prevent it from drying out.
Supervise young children – Borax safety is important, so make sure kids wash their hands after making the balls.
Fun Variations (Customize Your Homemade Bouncy Ball!)
Want to make an extra cool bouncy ball? Try these fun ideas!
Multicolored Bouncy Balls – Swirl different colored glues together before mixing with borax.
Glow-in-the-Dark Bouncy Ball – Use glow-in-the-dark glue or mix in glow paint for nighttime play.
Extra Sparkly Bouncy Ball – Mix fine glitter into the glue for a dazzling effect.
Different Sizes – Use more glue for a jumbo bouncy ball or less for a tiny one.
How to Make It a Learning Activity (STEM Science for Kids)
Turn this into a STEM science experiment by asking fun questions:
What happens if you add more glue?
Does more borax make the ball bouncier?
Does the surface affect how high it bounces?
Try measuring bounce height on different surfaces like tile, carpet, or wood!
Troubleshooting: Why Isn’t My Bouncy Ball Working?
If your DIY bouncy ball isn’t bouncing as expected, check these common issues:
Problem: The Ball is Too Sticky
Fix: Dip it back into the borax solution for a few seconds to firm up.
Problem: The Ball is Too Hard and Won’t Bounce
Fix: Use slightly less borax next time.
Problem: The Ball Won’t Hold Its Shape
Fix: Let the glue sit in the borax solution a little longer before shaping.
Problem: The Ball Cracks or Breaks Apart
Fix: Store it in a sealed plastic bag to prevent drying out.
Problem: The Ball Doesn’t Bounce Very High
Fix: Adjust the glue-to-borax ratio for a softer, more elastic texture.
