Grow non-toxic crystals on your window that look like frost. These easy crystals grow in a few minutes and give you the effect of frost, even if it's warm!
Crystal Frost Materials
- 1/3 cup Epsom salt (magnesium sulfate)
- 1/2 cup hot water
- few drops liquid dishwashing detergent
Prepare the Crystal Frost Paint
- Dissolve the Epsom salt in the hot water.
- If the salt doesn't completely dissolve, microwave the solution for about 30 seconds.
- Add a few drops of liquid dishwashing detergent. The detergent helps make the crystals easy to wipe away when you're done with them.
- Use a paper towel or rag to wipe a window with the solution. Crystals will form in a matter of minutes.
Helpful Tips and Tricks
- Make certain the Epsom salt is dissolved. If there are salt grains in the solution then the window will have uniform crystals rather than random-looking "frost".
- Use your finger to "write" on the window. The invisible text will act as a center for crystal growth, producing an interesting effect.
- Other smooth surfaces work well. Try a mirror, a metal pan or a translucent plate.
- When you're done with the frosted window, you can wipe it away with a damp cloth.
