ABSTRACT:
A process of allowing one to paint or draw on snow whereby a coloring agent, such as food coloring, is mixed with a gelling agent, such as household gelatin, and applied with a spray or squirt gun. When the gel solution contacts the cold snow, the gel solution quickly sets up and is prevented from dissipating as snow undergoes partial melting. When snow melts, the gel liquifies and disappears with runoff water.
