Materials:

  • Borax Powder
  • Water
  • Elmer's White Glue
  • Food Coloring (optional)
  • A plastic spoon (for stirring)
  • Two disposable cups
  • A tablespoon (for measuring)
  • Plastic bag (for storing)

Procedure

  1. Fill one small cup with water and add a spoon full of borax powder. Stir then set aside.
  2. Fill another small cup with 1inch or 2.5cm of glue.
  3. Add 20mL of water to the glue and mix.
  4. Add few drops of food coloring to the water and glue mixture. Then stir.
  5. Add 1 tablespoon of the Borax solution, you made earlier, to the water and glue mixture.
  6. Watch the slime form!!!! After it forms let it sit for about 30 seconds.
  7. Start playing with the slime!!!

Safety Precautions:

  • DO NOT EAT THE SLIME!!!!
  • The food coloring may stain surfaces, so do not put the slime directly on surfaces.
  • Remove dry slime by soaking it with water.
  • When not playing with the slime place it in a plastic bag.

Scientific Principles:

  1. Slime is a polymer it is both liquid and solid
  2. It is like a liquid because it takes the shape of any container
  3. It is like a solid because you can pick it up
  4. Polymer molecules chain themselves together, they can bend and stretch like chains.
