|This is perfect to create privacy, such as in a bathroom, or for shielding an ugly view. Make sure your windows are clean before you start.
Dissolve 4 heaping tablespoons of Epsom salts in one cup of beer. This will foam. Let set for at least 30 minutes. The salt crystals will partially dissolve.
Apply to window. This can be done with a 2 inch paint brush, but for a nicer effect, dip a facial tissue or terry cloth in the liquid and wipe over the window as if you were washing it. Then while the window is still wet go back and dab and pat at the glass with the wet tissue.
Mixture dries to form beautiful crystals. This looks even better the next day, and lasts a long time. It can be washed off with water and a cloth and is easily reapplied.
