  • 6 bottles clear Elmer's Glue (one for each color) or 4 ½ cups clear glue divided into ¾ cup increments 6 ounce bottles
  • 1 1/2 cups warm water, divided 1/4 cup for each batch
  • 3 teaspoons baking soda, divided 1/2 teaspoon for each batch
  • 6 tablespoons contact lens solution, divided containing boric acid, 1 tablespoon for each batch
  • Food coloring in red, blue, yellow, and green
  • Toys or foil confetti if desired


  1. You will make six separate batches of slime with one in each color.
  2. Empty the glue into a large bowl.
  3. Fill the empty glue bottle about ⅓ full with warm water (about ¼ cup) and seal with the lid. Shake well to combine the remaining glue with the water. Pour into bowl with glue and stir to combine.
  4. Add the baking soda to the glue and stir to mix thoroughly.
  5. Add food coloring to each bowl to make the colors of the rainbow: red, orange, yellow, green, blue and purple. I have listed how many drops were used in this recipe in the notes section. Stir the color in well.

  6. If you are adding additional glitter, confetti, or other items, stir it into the glue mixture.

  7. Add contact lens solution to the glue mixture and stir well. (Note: regular glue will require less contact lens solution than glitter glue. Add the contact lens solution slowly, mixing between additions, and add only enough to bring the glue together into a soft ball.)
  8. Remove the slime from the bowl allowing any excess liquid to remain in the bowl. The slime will be sticky. Begin to play with the slime, kneading it as you would bread dough, to bring the slime together. The slime is ready when no longer sticky.
  9. Best if stored in an airtight container in the refrigerator when not in use.
