Step 1: Prep Your Borax Solution: In one cup, pour ½ cup of warm water, then add 1 tablespoon of borax powder. Stir really well until all the borax crystals have dissolved completely. This is your activator.
Step 2: Mix Your Color Base: In a separate cup, combine 2 tablespoons of white school glue, 1 tablespoon of cornstarch, and a few drops of your chosen food coloring or gel dye. If using glitter or glow-in-the-dark paint, stir it in now. Mix until smooth and beautifully colored.
Step 3: The Magic Reaction Begins: Add just ½ tablespoon of your borax solution (from Step 1) to your colorful glue mixture. Stir quickly! You'll notice it immediately starts to come together, forming a clumpy, gummy blob.
Step 4: Knead to Perfection: Gently scoop out the clumpy mixture and start kneading it with your hands for about 2 minutes. It might feel sticky at first, but with persistence, it will become smooth, less sticky, and super pliable.
Step 5: Repeat for More Colors: To create more colors, repeat Steps 2-4 for each additional color you want to make. It's recommended to use a separate small bowl for each color to keep them distinct.
Step 6: Create Your Rainbow Masterpiece: Once you have all your colored blobs, take small pieces of each color and press them together. Gently roll them between your palms, applying even pressure, until they form a perfect, vibrant sphere. Your bouncy ball is ready!
