1 cup warm water
1 tablespoon borax powder
1/2 cup cornstarch
In a bowl, mix the warm water and borax powder until the borax is completely dissolved.
In a separate bowl, add the cornstarch.
Slowly pour the borax solution into the cornstarch while stirring continuously.
Keep stirring until the mixture thickens and becomes difficult to mix.
Use your hands to shape the mixture into small balls.
Let the balls dry for about 48 hours before using them to play.
Add food coloring to the borax solution for colorful bouncy balls.
Mix in glitter or glow-in-the-dark powder for extra flair.

If the balls get too hard, briefly soak in warm water to soften.
Bounce best on hard surfaces like tile or wood.
