... Make needle-like frost on your windows with Epsom salt.

If you live in a climate that does not see a great deal of snow and frost, or if you simply would like to create a little bit of winter in the summer, frost your windows using an Epsom salt solution. Epsom salt forms a crystalline structure much like ice crystals do, and this layer of crystal can be applied to a window or any other glass surface. Use this project to teach your children about crystalline structures.

Pour 1 1/2 cups of water into a cooking pot and place the pot on the stove.

Step 4

Remove the mixture from the heat and allow it to cool slightly.

Step 5

Mix in 3 tbsp. of liquid dish detergent.

Paint the mixture onto the window using a paintbrush. The "frost" will start to form as the solution dries.


Remove the frost by wiping it away with soap and water.

Paint the solution over a stencil to create frost designs.
