What is this stuff?
This powder is a patented, safe, non-toxic, environmentally friendly polymer developed specifically to imitate most of the properties of snow. These polymers can expand 100 times their original size! It can be cool to the touch because it is 99% water. It will not melt or blow away and can be used on almost any surface, indoors or outside. Use surface protection for untreated wood and moisture-sensitive surfaces.
How to make your own snow storm:
Add 1/4 cup water to 1 teaspoon of powder. You can add another 1/4 cup for more volume.
