Why Isn't My Slime Glowing Brightly in the Dark?

Glow-in-the-dark slime is kind of like a battery: it needs to be "charged" to work! Ask an adult to hold your slime close to a lit lightbulb for a few minutes. After, when you turn off the lights, it should glow a lot. Repeat this whenever you need to!

Special Safety Note About Slime:

Slime is a great activity for many ages! All recipes are meant for children out of the mouthing stage and close supervision is recommended. When making slime recipes with borax, be sure to use the borax under adult supervision or have an adult be in charge of that ingredient. Borax should never be eaten and should be kept out of the reach of small children. Once slime time is over, children are encouraged to wash their hands thoroughly.
