Popis:	We have created laboratory conditions similar to those present in a lake when the external temperature falls below 0°C. Glaciation in lakes is described in school textbooks and classroom demonstrations.1,2 It is pointed out how the anomalous behavior of water, which reaches maximum density at about 4°C,3 makes life possible on Earth. The proposed model thus describes a physical system that, apart from being of interest in itself, is relevant to the study of biological mechanisms.
