Cosmic Slime Recipe

supplies needed

  • 1 (5 fl oz) Elmer’s Blue Colour Changing Glue
  • 1 (5 fl oz) Elmer’s Purple Glow Glue
  • 1 (5 fl oz) Elmer’s Pink Metallic Glue
  • Elmer’s Magical Liquid (at least 6.9 fl oz)
  • Container for Mixing
  • Mixing Utensil
  • Measuring Spoons


  1. Pour out one (5 oz) Elmer’s Glue into a container.

  2. Add 2 tablespoons of Magical Liquid and mix well. Then add 1 more tablespoon of Magical Liquid and mix.

  3. Mix until well incorporated. You will notice the mixture becoming harder to mix and slime begins to form.

  4. If needed/too sticky, add a little magical liquid (1/2 tablespoon) at a time to get desired feel of slime. Take the slime out and begin kneading with both of your hands.

  5. For each of the remaining glues, repeat steps 1-4. 6. Once all three colours are created, lay all colours on top of each other then swirl and twist your slime! If you knead too much, the colours will eventually mix and become one.

  6. Before kneading too much, go outside and watch part of your slime change colour in the bright sun OR watch part of your slime Glow in the Dark!
