Preparation:

Step 1: Prepare the Borax Solution

• In a small bowl, add 1 tablespoon of borax powder to 1/4 cup of warm water.
• Stir the mixture until the borax is fully dissolved. This will create a borax solution that will help form the structure of the bouncy ball.

Step 2: Mix Glue and Cornstarch

• In a separate mixing bowl, pour in 1/2 cup of white school glue.
• Add 1/4 cup of cornstarch to the glue.
• Stir in 1 tablespoon of water, mixing everything until smooth and well combined.

Step 3: Add Color

• If you’d like to make your bouncy ball colorful, add a few drops of food coloring to the glue mixture.
• Stir well to evenly distribute the color throughout the mixture.

Step 4: Combine the Mixtures

• Slowly pour the borax solution into the glue and cornstarch mixture while stirring.
• As the two solutions mix, the glue will start to harden and take on a more solid consistency.
• Continue stirring until the mixture begins to form a semi-solid mass.

Step 5: Knead the Ball

• Once the mixture starts forming, take it out of the bowl and begin kneading it with your hands.
• Knead for about 2-3 minutes until the ball becomes smooth and pliable.
• If the mixture feels too sticky, add a little more cornstarch.
• If the ball feels too hard or crumbly, add a few drops of water and knead again.

Step 6: Shape the Ball

• Roll the kneaded mixture into a smooth and round ball shape.
• Make sure to compact the ball tightly to prevent it from falling apart when bouncing.

Step 7: Let It Dry

• Allow the bouncy ball to sit and dry for a few hours.
• Once fully set, it is ready to bounce and play with!
