Ibu got some snow powder that turns some white powdery substance that looks like real snow when you pour water on it. It doesn’t melt but if it dries out all you do is spritz a little more water on it and soft and fluffy to the touch. And its really messy although it's easier to clean than sand.
Instant snow powder is made of some very large molecules (polymers) composed of repeating units that are hydrophilic, or ‘water-loving.’ Most synthetic polymers are not hydrophilic; plastic soda bottles, PTFE (Teflon®) coatings, and PVC pipe, for example, are not.

As you add water, the powder acts like a bunch of very tiny but very good sponges. When you look at a regular kitchen sponge, you can see the pores that the water fills in; with instant snow powder, the places the water occupies are way too tiny to see, but they’re still there. Fake snow’s chemical name is ‘sodium polyacrylate,’ but the absorbent polymer in disposable diapers goes by the same name, because they have very similar chemical structure. Most people call instant snow by its simple name for clarity. Depending on who you ask, polymer ‘snow’ was first developed either as a blood absorber for hospitals or as a material to use in indoor snowboard parks in Japan. However it was invented, it’s awesome!
