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.

The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
