Glow in
the Dark Goo
The Science Behind Why Things
Glow in the Dark
For 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.
