DIY Rainbow Unicorn Slime

Raise your hand if you love playing with slime!

Science Educator Becky Wolfe and her daughter MJ show you how to make slime at home with a few household ingredients. This experiment was inspired by Living Locurto.

Materials:

  • White glue
  • Foaming shaving cream
  • Borax powder
  • Water
  • Blue, pink and yellow neon food coloring

Process:


  1. In a large bowl mix glue and shaving cream with a spoon.
  2. In a separate bowl or cup, mix 1/2 teaspoon of Borax in 1 cup of water. Stir until the borax is dissolved. 
  3. Add about a teaspoon of the borax and water mixture into the glue/shaving cream bowl and stir.
  4. Knead with your hands and if it's too sticky, add a tiny bit more borax and water mixture.
  5. Separate your fluffy slime into three pieces.
  6. Add a drop of blue food coloring to the first piece of slime and knead until the entire piece is blue.
  7. Repeat with the other two pieces of slime by adding one drop of pink and one drop of yellow to them.
  8. When all three pieces are colored, add them together.
  9. Gently knead the fluffy slime until you have a pretty mixture of the rainbow. The longer you knead this slime, the more the colors will become one!

What's going on:

When we make slime, we are creating a polymer, which is a substance that is made of long strings of molecules. "Mer" means a repeating unit, so a polymer is many units. In the slime, the borax reacts with the glue molecules and connects them together in long strings.
