Insta Snow is an amazing powder that turns ordinary water into a fluffy fake snow that looks like the real thing. It can be used to make incredibly realistic snow. Just add water and watch the white powder expand to 100 times its original size. Includes an activity guide that can be used to teach the science behind the erupting snow. Choose between jar (100 grams, makes two gallons of fake snow) or bag (454 grams, makes eight gallons of fake snow).
