Materials Needed
Before you start, gather these supplies:
Ingredients:
- ½ cup warm water
- 1 tbsp Borax powder (the key to bounce!)
- 1 tbsp white school glue
- ½ tsp cornstarch (for firmness)
- Food coloring (neon colors make it extra fun!)
Tools:
- 2 small cups
- Stirring sticks or spoons
- Measuring spoons
- Gloves (optional, but keeps hands clean)
How to Make a DIY Bouncy Ball
Follow these easy steps to create your own bouncy ball:
Step 1: Make the Borax Solution
- In a small cup, mix ½ cup warm water and 1 tbsp Borax powder.
- Stir until the Borax is completely dissolved.
Step 2: Prepare the Glue Mixture
- In a separate cup, combine 1 tbsp white glue and ½ tsp cornstarch.
- Mix well until smooth.
Step 3: Add Color
- Add 3-4 drops of food coloring to the glue mixture.
- Stir until the color is evenly distributed.
Step 4: Combine & Watch the Magic Happen!
- Slowly pour the glue mixture into the Borax solution.
- Do not stir! Just let it sit for about 15 seconds—you’ll see it start to solidify.
Step 5: Knead & Shape Your Ball
- After 15 seconds, use a spoon to scoop out the mixture.
- Knead it with your hands (wear gloves if preferred) until smooth.
- Roll it between your palms to form a perfect bouncy ball.
Step 6: Test the Bounce!
- Let it sit for a few minutes to firm up.
- Drop it from different heights to see how high it bounces!
Pro Tips for the Best Bouncy Ball
✔ Glow-in-the-Dark Ball – Swap food coloring for glow paint for a cool nighttime effect.
✔ Sparkle Ball – Mix in fine glitter before shaping for extra shine.
✔ Bounce Experiment – Test how high it bounces from different heights.
✔ Storage Tip – Keep your bouncy ball in a small container to prevent drying out.
FAQs About DIY Bouncy Balls
1. Why does Borax make the ball bouncy?
Borax reacts with the glue to form a polymer, creating a flexible yet firm structure that bounces.
2. Can I make a bouncy ball without Borax?
Yes! You can use liquid starch or contact lens solution (containing boric acid) as alternatives.
3. Why is my bouncy ball sticky?
If it’s too sticky, you may need more Borax solution or cornstarch to balance the texture.
4. How long do homemade bouncy balls last?
They can last a few days to a week if stored properly in an airtight container.
Final Thoughts
Making a DIY bouncy ball is a fantastic way to combine science and fun! This simple experiment teaches kids about chemical reactions while giving them a cool toy to play with.
Try different colors, glitters, or even glow-in-the-dark effects to customize your bouncy ball.
