Vincent Schaefer waves his scientific wand through snow cloud produced in a cold chamber

Man-made snow has been created for first time by Vincent Schaefer at the General Electric Research Laboratory.  Here Dr. Schaefer waves his scientific wand through snow cloud produced in a cold chamber.  Cloud was created by introducing moist air from the breath into minus 5 degrees fahrenheit temperature of atmosphere in the chamber.  The wand, cooled in liquid air to minus 70 degrees fahrenheit, leaves tiny ice germs in the cloud which grow at expense of water droplets comprising the cloud.  Result: man-made snow., Credit Line: AIP Emilio Segrè Visual Archives, Physics Today Collection
