Slime On A Dime: The Hottest Science Project For Kids And Summer Camps

Slime has become a very popular science project for kids this year. With S.T.E.M becoming more popular in after-school programs, numerous recipes for slime have started to pop up. So we thought we’d pass along one of our favorites for glow in the dark slime!

Elmer’s glue gel
4% (saturated) borax solution
Non-toxic glowing paint


The slime is made by combining two different solutions. The ratio is 3 parts glue to 1 part borax, and then you add in the glowing paint for that extra pizazz.

  1. First, you can make a glue gel solution by mixing 1 part of glue gel (either clear or pale blue) with 3 parts of warm water.
  2. Stir in the glow paint. You can find glowing paint at some paint stores or glowing paint powder at craft stores. This paint needs to be mixed in very well. It won’t ever dissolve but it needs to be spread evenly throughout the mixture.
  3. The other solution you need is a saturated borax solution. You can make a saturated borax solution by stirring borax into warm water until it stops dissolving, leaving borax at the bottom of the glass.
  4. Mix together 2 tablespoons of the glue gel solution with 2 teaspoons of the borax solution. You can use a spoon and a cup or you can just squish it together with your hands or inside a sealed baggie.
  5. The phosphorescent glow is activated by shining a light on the slime. Then you turn out the lights and it will glow.


Store your slime in a baggie or other sealed container to keep it from evaporating. You can refrigerate it if desired. The slime cleans up easily with soap and water.
