Abstract

The results of experimental studies of the spontaneous rotation of ice blocks of different sizes placed both on a solid surface (aluminum, polymethyl methacrylate, glass, foam plastic, ceramics) and on the surface of a pool with water of a certain depth at a given temperature are presented. Observations have shown that if an ice block is placed on the water surface, a pronounced vertical flow is formed under the ice-water interface, which causes rotation. During the experiments, it was found that the speed of rotation of the ice block increases with the temperature of the water on the surface of which the block is placed. It has been experimentally established that with an increase in the mass of an ice block, its rotation speed increases. All observed flow patterns are stably reproduced by repeating the experiments and maintaining the conditions within the accuracy of the experiments.
