How to make glow-in-the-dark slime

There are lots of different methods to making this fun craft with kids. You can buy glow paint in different colors at the craft store. You should try these to see how each of the colors glow. Maybe blend the different colors together after the slime has been made for really cool effects.

Step 2

While wearing gloves, mix all of the ingredients together until slime begins to form. It will feel a little rubbery but will stretch easily.

Tip:  We found that there was a little excess liquid in the bowl once our slime was mixed together. If there is you can just toss that away.

Step 3

Leave your slime on a paper plate or in a container under natural or artificial lights. This will help to activate the glow paint. The longer it’s under the light, the better it will glow.
