When water is added to this granular white powder, it instantly expands to 40 times its original volume, producing a snow-like material. Great for showing that there is No Law of Conservation of Volume! This artificial 'snow' is fluffy and can be readily poured. When wet, it adheres well to boots and is very slippery. It was used in Steven Spielberg's mini-series, Band of Brothers and is becoming popular as an artificial base for skiers. It even can be used to turn white wine into snow… hmm! You can carry almost two cubic meters of snow in your briefcase; just add water! Its MSDS is the same as for sodium polyacrylate, the 'diaper' polymer! This is a great demonstration of interest to students and educators of ALL ages and abilities. We reserve the right to limit quantities.
