Preparation:

Step 1: Prepare the Borax Solution

In a small mixing cup, add 1/2 cup of warm water. Slowly stir in 1 tablespoon of Borax powder, mixing until it dissolves completely. This solution will help form the polymer chains that make the bouncy ball elastic.

Step 2: Mix Glue and Cornstarch

In a separate cup, pour 1 tablespoon of white school glue. Add 1/2 teaspoon of cornstarch and stir well. Cornstarch helps give the ball structure and make it more solid rather than gooey.

Step 3: Add Food Coloring

If you want a colorful bouncy ball, mix in a few drops of food coloring into the glue and cornstarch mixture. Stir until the color is evenly distributed.

Step 4: Combine the Mixtures

Slowly pour the glue mixture into the Borax solution. Do not stir immediately; let it sit for about 10-15 seconds. You’ll notice the glue mixture starting to solidify.

Step 5: Stir and Knead the Ball

Begin stirring the mixture until it starts clumping together. Once it becomes difficult to stir, use your hands to remove the forming ball from the liquid. Knead it in your hands until it firms up and is no longer sticky.

Step 6: Shape the Ball

Roll the ball between your palms to make it round and smooth. The more you roll and press it, the better it will hold its shape.
