Film Specifications - 16 mm film ; Description - From Container, Film # 3, Title, Producer, American Meteorological Society, distributed by Universal Education and Visual Arts. Film depicts an intro by a scientist speaking in front of an active satellite. Demonstrates how water droplets are captured on slides. Slide coated with oil, droplets captured, then examined under microscope to observe size and characteristics, including nuclei. Particles in chamber, pumped, grow droplets from molecules, nucleus dissolves, reached maximum size, measured in microns. Nylon stocking is valuable tool in gathering raindrops. Slow-motion film examines drop falling through it. Size compared. Large balloon to marble and BB. 1 Million times the size. Time-lapse film of water droplets forming. Reproduce formation of cloud in laboratory. Beam of light over layer of water in glass box. Additional tools and processes complete experiment. Microscopic analysis. Droplet sizes compared. How rain is formed from droplets. Time-lapse photography of glass of ice water. Droplets combine. Happen in Clouds? Chalk dust demo. Speed, size and direction of droplets. Water tank demo. Large droplets fall faster than small ones. They do not combine. Electric charges and fields affect droplets. They combine. More experiments, slo-mo photography. Introduce air. Shots of clouds and rain. Over water vs over land. Forest fire smoke, industrial smoke affect nuclei. Cloud particles gathered from aircraft examined under microscope. Tempertures discussed. Wispy appearances. Ice crystals discussed. Larger than ice droplets. Ice crystals merge into snowflakes. Film shots over Boulder from NCAR. Types of clouds and what they bring. Diagram shown and coallence formations are discussed. ; Location - NCAR Mesa Lab, Boulder, Colorado. ; Color ; Sound ; Date - 1964 ; Reel Size - 12" ; Approx. Film Length - 950' ; Approx.
