ABSTRACT:
A method and apparatus for continuously making and distributing snow. The apparatus includes a first and second tube through which compressed air and water are flowed. The tubes have outlet portions where the water and air impinge on a cup shape nozzle head. The air and water are flowed at a substaintially constant pressure but the decompressed air has a greater velocity at the outlet portion than the water to aid in cooling. The water impinges on the atomizing surface of the nozzle head to produce small droplets which in the ambient creates snow for example for skiing.
