Ingredients:

1 tablespoon Borax powder
½ cup Warm water
2 tablespoons White school glue (like Elmer’s)
1 tablespoon Cornstarch
Food coloring (variety of colors for tie-dye effect)
2 small mixing bowls
Stirring sticks or spoons
Disposable gloves (optional, to avoid staining)
Measuring spoons
Plastic baggies or containers for storage

Instructions

Preparation: Step 1: Prepare the Borax Solution

In the first mixing bowl, combine 1 tablespoon of borax powder with ½ cup of warm water. Stir thoroughly until the borax is fully dissolved. This solution acts as a cross-linking agent, turning the liquid glue into a solid yet flexible material.

Step 2: Mix Glue, Cornstarch, and Color

In a second bowl, mix 2 tablespoons of white school glue with 1 tablespoon of cornstarch. Stir well to combine. Now, add a few drops of different food coloring to create a tie-dye swirl effect. Do not fully mix the colors; just swirl them lightly for that marbled pattern.

Step 3: Combine Both Mixtures

Pour the glue and color mixture into the borax solution. You’ll immediately see the substances start to thicken and form into a blob. Let it sit undisturbed for 15–20 seconds.

Step 4: Shape the Bouncy Ball

Using your hands (wear gloves if desired), take the ball out of the solution and begin kneading and rolling it between your palms. It may feel sticky at first but will become more solid and bouncy as you work it. Knead for about 1–2 minutes until it is smooth and firm.

Step 5: Let it Set and Store Properly

Allow the ball to dry for 5–10 minutes. Once dried slightly, it’s ready to bounce! Store your tie-dye bouncy ball in an airtight container or plastic baggie when not in use to keep it from drying out.

Notes

Even though this activity uses kitchen ingredients, these bouncy balls are not edible. Always supervise young children to prevent ingestion. Also, ensure that all mixing is done in containers not used for food preparation.
