Ice Flowers

This 1930's black and white silent film shows the formation of ice flowers within the structure of ice as it melts. Probably an excerpt from a teaching film on the subject of Tyndall's Ice Flowers, it allows the viewer to look through a microscope and see the naturally occurring crystalline forms which build up within ice as it freezes. These are produced at a rapid rate so it is only as the ice melts through the absorption of heat that the formation of the structures appears.
