3.9 based on 27 ratings

What You Need:

  • 1 cup Epsom salts (available at your local pharmacy)
  • 1 ½ cup water
  • One quart heat-proof container
  • Liquid dishwashing detergent
  • Small paintbrush
  • Piece of plan glass or the window itself!
  • Spoon

What You Do:

  1. Add 1 ½ cups of water to a heat proof container.
  2. Over a hot plate or stove heat the water to boiling.
  3. Gradually add some of the Epsom salts and stir keeping the solution boiling during the process.
  4. Add more Epsom salts and stir.
  5. Repeat until the Epsom salts will no longer dissolve and can be seen settled to the bottom of the container.
  6. Remove container from heat and add some liquid dishwashing detergent and stir.
  7. Let the mixture cool.
  8. “Paint” the solution on a window or glass with a paintbrush. When the solution dries, needle-like crystal fan patterns will appear, looking like frost on the window.

Haven’t had enough? Allow your child to experiment by painting the Epsom salts solution on other surfaces to see if he will produce the same affect. If using a window in the house it can be cleaned by simply washing it with soap and water.
