What’s This All About?

Today, we’re diving into the colorful world of homemade bouncy balls—yes, the kind you bounce all over the kitchen floor and maybe even (accidentally!) down the stairs. This recipe uses simple household ingredients to create a science-meets-craft activity that’s equal parts fun and educational.

These DIY bouncy balls come together with just a few ingredients—no fancy supplies, no long waits—and they’re just as fun to make as they are to bounce around!

Why You’ll Love Making These

• Quick to make – Done in under 30 minutes (not counting drying time).
• Budget-friendly – You probably already have the ingredients at home.
• Hands-on learning – Teaches kids about polymers and chemical reactions.
• Customizable – Make them any color, shape, or size you want!
• Screen-free fun – Keeps hands and minds busy in the best way.

What Do These Feel Like?

These bouncy balls are soft and rubbery with just the right bounce. They’re not as firm as store-bought versions, but that’s part of their charm! Each one is unique, a little unpredictable, and 100% made with your own two hands. How cool is that?

Benefits of This Craft

• Educational: Great for introducing STEM concepts like non-Newtonian fluids and polymers.
• Sensory play: Mixing, kneading, rolling—all fantastic for sensory development.
• Creativity booster: From choosing colors to testing bounce height, kids get to explore cause and effect in a hands-on way.
• Great for groups: Perfect for birthday parties, classrooms, or sibling craft time.

What You’ll Need

🧪 Ingredients:

• 1/2 cup white school glue
• 1 tablespoon borax powder
• 1 tablespoon water (for glue mixture)
• 1/4 teaspoon food coloring (optional but fun!)
• 1/4 cup cornstarch
• 1/4 cup warm water (for borax solution)

🧰 Tools:

• 2 small mixing bowls
• Measuring spoons and cups
• A spoon or craft stick for stirring
• Hands for kneading!
• Wax paper or parchment for drying

Ingredient Substitutions & Add-Ons

• No food coloring? Try glitter glue or glow-in-the-dark paint.
• Want more bounce? Experiment with slightly less cornstarch.
• Add scents using a drop of essential oil (lavender or citrus is nice!).
• Try shapes: Make mini marbles or heart-shaped squishies using silicone molds.

How to Make Your Own Bouncy Ball

🧤 Step 1: Make the Borax Solution

In a small bowl, combine 1 tablespoon borax powder with 1/4 cup warm water. Stir until the powder dissolves completely.

🧴 Step 2: Mix the Glue Base

In another bowl, mix together:

• 1/2 cup white glue
• 1/4 cup cornstarch
• 1 tablespoon water

Stir until smooth. This is your gooey base!

🌈 Step 3: Add Color (Optional but Awesome!)

Mix in a few drops of food coloring. Stir well to blend the color evenly—this is where the magic begins.

🌀 Step 4: Combine the Two

Slowly pour the borax solution into your glue mixture while stirring constantly. It will begin to thicken right away—this is the polymer reaction in action!

✋ Step 5: Knead & Work the Dough

Remove the mixture from the bowl and knead it in your hands for 2–3 minutes. If it’s too sticky, sprinkle on a bit more cornstarch. Too dry? Add a tiny splash of water.

⚪ Step 6: Shape the Ball

Once you have a smooth texture, roll the mixture between your palms to shape a ball. Take your time here—smoothness helps with bounce!

💨 Step 7: Let It Set

Place your bouncy ball on wax paper and let it dry for a few hours. This helps it firm up and get to peak bounciness.

What to Do With Your Bouncy Ball

• Test it on different surfaces: tile, hardwood, or even a trampoline!
• Have a bounce-off between friends: whose ball goes higher?
• Use it in a DIY pinball-style box game.
• Turn it into a gift: wrap a few in a little baggie with a tag that says “Bounce into fun!”

Tips for Bouncy Ball Success

• Use warm water for the borax—it dissolves faster.
• Don’t skip the kneading—this is where the texture really comes together.
• Start small: Make one ball at a time to get the feel before scaling up.
• Clean hands help! Cornstarch and glue stick less to dry hands.

Storage Tips

• Store in an airtight container or ziplock bag to prevent it from drying out.
• If it flattens, reshape it and roll it between your palms again.
• Avoid storing in hot or humid areas—it can lose bounce or get sticky.
• If it becomes too hard, you can revive it slightly with a drop of water and more kneading.

Frequently Asked Questions

Can I use clear glue instead of white?

Yes! It will create a slightly different texture and a cool transparent effect.

Is borax safe?

In small quantities and with adult supervision, it’s safe for craft use. Be sure to wash hands after handling, and don’t ingest the ball—it’s a toy, not a snack!

Why isn’t my ball bouncing?

It may need more kneading, or it could be too dry or wet. Adjust by adding cornstarch or a few drops of water and work it through again.

How long will it last?

A few days to a week, depending on how it’s stored. After that, you might want to make a fresh one—it’s quick and fun every time!
