This formula for green slime comes from our friend Professor Figgy. Tools and materials are available at grocery and crafts stores. To make a fluorescent variation, replace the water being used to make your two solutions (one with the glue and one with the Borax) with Glow Water.



  • 2 mixing bowls

  • Warm water

  • Elmer's glue

  • 1/4 teaspoon unsweetened Kool-Aid or 4 to 8 drops liquid food coloring

  • Craft stick

  • Borax


  1. Mix together 1/3 cup warm water, 1/2 cup Elmer's glue, and Kool-Aid or food coloring. Stir thoroughly with craft stick; set aside.

  2. Mix together 3/4 cup warm water and 2 teaspoons Borax. Stir thoroughly with craft stick; pour into mixture one, stirring continuously.

  3. Remove glob from bowl and work in your hands for 2 to 3 minutes. Store in resealable plastic bag or air-tight container. (Tip: If mixture starts to dry out, pour a small amount of water over it and knead for 2 to 3 minutes before returning to a tightly sealed container.)
