  3. Pour 4 ounces of white glue into a bowl.
  4. Add one tablespoon of water and swirl until smooth.
  5. Sprinkle in a teaspoon of glow powder.

  8. Prepare your borax solution by dissolving half a teaspoon in one cup of warm water.
  9. Slowly add borax solution while stirring until the mix becomes rubbery.
