Glow in the Dark Goo
The Science Behind Why Things Glow in the DarkFor something to glow in the dark, it requires chemicals that store energy when exposed to light. These substances are called phosphors which radiate light after being “energized” or exposed to light. Once you expose them to light, they slowly release this energy in small amounts of light which causes the objects to glow in the dark.
Borax and Glue Glow in the Dark Slime, glue, borax, fluorescent dye
- 1 cup warm water
- 4 ounces clear non-toxic liquid glue (you can use white glue, but the slime will be opaque)
- 3 tablespoons glow in the dark craft paint (or 1 teaspoon glow powder)
- 2 teaspoons borax (sodium tetraborate or sodium borate, not boric acid)
1. Stir the glue and 1/2 cup of the warm water together until the mixture is uniform.
2. Add the glow paint (or whatever glow product you’re using) to the glue mixture.
3. In a separate container, dissolve the 2 teaspoons borax in 1/2 cup warm water. It’s fine if it doesn’t all dissolve.
4. Stir the borax solution into the glue mixture. Use your hands or a spoon to mix the ingredients together to make the glowing slime. You may have excess liquid, which you can discard.
5. Glow products store light and release it slowly, so expose the slime to sunlight or bright lights to see it glow in the dark. Store the slime in a sealed container when you’re not using it to make it last up to a couple of weeks.
