Abstract
A method and apparatus for continuously making snow at all times of the year comprises the creation of countless ice crystals from a mist in a controlled environment. The mist may have a ice crystal nucleus added to it to facilitate the development of the ice crystal at higher temperatures. The ice crystals are directed into an ultrasonic field generated by an transducer where the fall rate of the crystals levitated. While the crystals are within the ultrasonic field, the crystals grow into snowflakes as a result of collisions with other crystals. The snowflakes eventually fall out of the ultrasonic field as snow having a more natural appearance than more conventional snow-making techniques.
