A 1930s black and white silent film showing the formation of ice flowers within the structure of ice as it melts.
Probably an excerpt of a teaching film on the subject of Tyndall’s Ice Flowers, this film allows the viewer to look through a microscope and see the naturally occurring crystalline forms that 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.
