Ingredients:

  • 4 fl oz (118 ml) Elmer's White School Glue (or clear glue)
  • ½ tsp (2.5 ml) Baking Soda
  • 1 tbsp (15 ml) Contact Lens Solution (containing boric acid and sodium borate)
  • Gel food coloring (red, orange, yellow, green, blue, purple)
  • Optional: Glitter (various colors and sizes)

Instructions:

  1. Pour the entire bottle of Elmer's glue into the mixing bowl.
  2. Stir in the baking soda until well combined.
  3. Slowly add the contact lens solution, stirring constantly. Start with half, then add more gradually until the slime starts to pull away from the bowl and forms a cohesive ball.
  4. Knead the slime with your hands until it becomes smooth and less sticky. If it's still too sticky, add a few drops more contact lens solution.
  5. Divide the slime into six equal portions.
  6. Add a tiny drop of food coloring to each portion of slime and knead until the color is evenly distributed. Add glitter and knead.
  7. Gently twist and swirl the different colored slimes together to create a rainbow effect.
  8. Store the slime in an airtight container to prevent it from drying out.
