Title
Let it snow...
Abstract
The article discusses the production and composition of artificial snow. Snow machines used by ski resorts atomise water combined with additives that work as ice nucleators, while fake snow made for motion picture use include products such as paper, starch, or polystyrene polymers. Some scientists are concerned about the environmental impacts of water extraction for artificial snow-making by ski resorts, as much of it evaporates rather than return to the water supply.
