Abstract:
1. A method for making intermediate quality snow comprising the steps of: a) incorporating an amount of organopolysiloxane surfactant into water at a concentration of from about 2 to about 50 ppm organopolysiloxane to produce a snow property enhancingly effective composition; b) feeding a continuous flow of said composition under high pressure and at a low temperature to at least one orifice; c) continuously mixing with said flow of said composition a stream of compressed air to form a composition and compressed air mixture at a rate amounting to a minor proportion by weight of said air with reference to the composition; and d) discharging the composition and compressed air mixture from said at least one orifice in the form of small droplets into the atmosphere at a temperature below freezing; whereby at least some of the small droplets crystallize to form intermediate quality snow.
