How to Make a Glow in the Dark Slime Stress Ball

A slime stress ball doesn’t have to be boring. With glow in the dark slime, you can turn simple sensory play into a fun, calming experience that looks great in the light — and even better in the dark. This DIY project is easy, hands-on, and perfect for kids, families, or anyone looking for a relaxing sensory activity. Follow the steps below to make your own glowing slime stress ball at home.

Step 1: Choose the Right Glow in the Dark Slime

Start with a thick, elastic glow in the dark slime. A non-sticky texture works best, as it helps the slime hold its shape and bounce better.
If the slime feels too soft, knead it for a minute to improve elasticity.

Step 2: Knead and Remove Air

Use both hands to knead, press, and fold the slime repeatedly.
This step removes trapped air and helps create a firmer slime stress ball with better rebound.

Step 3: Shape the Slime Ball

Slowly roll the slime between your palms to form a smooth, round ball.
Gently tighten the surface as you roll to keep the shape compact and even.

Step 4: Chill to Set

Place the slime ball in the refrigerator for 10–15 minutes (do not freeze).
Cooling helps the slime set, improving bounce and overall durability.

Step 5: Charge and Test the Glow

Expose the slime ball to bright light or sunlight for a few minutes.
Turn off the lights to enjoy the glowing effect, then gently drop or squeeze it to test its bounce and stress-relief feel.

Tips for a Better Slime Stress Ball
