Abstract: | It is established experimentally that at temperatures above 0°C formation of methane hydrate starts with the appearance of thin films of this substance on the surface of water; during isothermal storage, the films permeate throughout the whole volume of the sample. The maximal content of methane hydrate is several (volume) per cent. The viscosity of the sample is much lower than that of ice and much higher than that of water. A. A.
