Looking for a fun, hands-on science activity that will wow the kids? This glow-in-the-dark slime recipe combines creativity, science, and sensory play all in one gooey project. It’s safe, easy to make, and guaranteed to light up the room-literally!
What Makes Glow-in-the-Dark Slime Special?
Unlike regular slime, glow-in-the-dark slime contains phosphorescent materials that absorb light and re-emit it in the dark. This makes it both educational and magical for kids. It also opens the door for learning about light, energy, and chemical reactions.
Ingredients You’ll Need (and Links to our favourite Ingredients!)
1/2 cup clear PVA glue (Elmer’s Clear Glue is ideal)
1/2 cup warm water
1 tablespoon glow-in-the-dark pigment or paint (non-toxic)
1/2 teaspoon baking soda
1 tablespoon saline solution
Optional: glitter or neon food coloring for extra flair
Step-by-Step Instructions
Step 1: Mix the Glue and Water
In a bowl, combine 1/2 cup of clear glue with 1/2 cup of warm water. Stir well until fully blended.
Step 2: Add Glow Pigment
Mix in 1 tablespoon of glow-in-the-dark pigment. Stir thoroughly to evenly distribute the glowing material.
Step 3: Add Baking Soda
Add 1/2 teaspoon of baking soda and mix. This helps give the slime structure.
Step 4: Activate with Saline Solution
Slowly add 1 tablespoon of saline solution while stirring. The slime will start to form and pull away from the sides of the bowl.
Step 5: Knead and Play
Once the slime becomes less sticky, take it out and knead it with your hands. It should be stretchy, glowy, and ready to play!
Safety Tips for Kids
Use non-toxic glue and pigment only
Always supervise young children
Store slime in an airtight container when not in use
How to Make Your Slime Glow Brighter
Charge it under light: Place the slime under a bright lamp or sunlight for 1-2 minutes before turning off the lights.
Use quality glow pigments: Phosphorescent powders are more effective than most glow paints.
Experiment with color: Neon food coloring enhances visibility even when it’s not glowing.
