🧪 Ingredients & Materials

1/2 cup warm water
1 tbsp borax
1 tbsp cornstarch
2 tbsp white school glue
Glow-in-the-dark paint or powder
Food coloring (optional)
2 small disposable cups
Popsicle stick or spoon for stirring
Latex gloves (optional but recommended)

🧤 Safety Note:

Although the ingredients are common craft supplies, always supervise children during the process and consider using gloves to prevent skin contact with borax.

🛠️ Instructions

Make the borax solution: In one disposable cup, pour in 1/2 cup of warm water. Add 1 tablespoon of borax and stir until fully dissolved. Set aside.
Prepare the glue mixture: In the second cup, mix 2 tablespoons of white school glue with 1 tablespoon of cornstarch. Add glow-in-the-dark paint or powder based on how bright you want the glow. Optionally, add a few drops of food coloring.
Create swirl effect: Stir gently to slightly combine colors without fully mixing for a cool marbled swirl look.
Combine mixtures: Pour the glue mixture into the borax solution. Let it sit for 10–15 seconds, then use your stirring stick or hands to gently roll it in the solution until it begins to form a ball.
Shape the ball: Once firm, take it out and roll it between your palms until smooth and bouncy.
Activate the glow: Place the finished bounce ball under a bright light for a few minutes to charge it. Turn off the lights and enjoy the glowing bounce!
Store: Keep your bounce ball in a ziplock bag or airtight container to maintain its bounce and softness.

💡 Tips & Variations

Boost the glow: Charge under direct light for at least 5 minutes for maximum luminescence.
Customize the design: Use different glow pigments and food coloring combinations to make multi-color swirl patterns.
Use molds: Pour the mixture into silicone molds for fun shapes like stars, hearts, or animals.
Educational value: Great STEM project to teach about chemical reactions and polymers.

📦 Storage Instructions

Store your finished bounce balls in individual resealable plastic bags to prevent drying out. If the ball becomes too firm over time, knead it gently to bring back some flexibility.

👩‍🔬 Science Behind It

The glue contains polyvinyl acetate, a polymer that reacts with borax to form a rubbery, flexible material. This cross-linking of polymers is what makes your bounce ball stretch, compress, and – of course – bounce!
