Science Behind It
Snow powder, also known as Instant Snow Polymer, is made by cross-linking molecules of the sodium polyacrylate polymer. This is the material which is used in hygiene products like baby diapers. When this material meets water, this powder absorbs water. And this superabsorbent polymer expands up to 100 times its original volume. This is why the powdery material produces a snow-like material. Another fact is when you dry out the fluffy snow, it turns back to its powdery form and you can use again.
