Abstract
Compressed air and water are mixed, and are accelerated to a jet of high velocity within a cylindrical, non obstructive device; the explosive decompression of compressed air to atmospheric pressure within a diverging exit nozzle disintegrates the jet of water into a jet of tiny droplets which freeze in contact with colder atmospheric air to ice crystals of snow.
