Ice has always been thought to be slippery because the pressure of the object in contact with it causes the thin layer to melt. Skate blades are thought to pressure the ice, melt thin layers and lubricate between ice and blades. This interpretation is called "pressure melting" and began in the 19th century. However, this does not take into account ice skating at temperatures below -3.5 ° C, while skaters often skate at low temperature ice. In the 20th century, another explanation called "friction heating" was proposed, in which the ice layer melts due to material friction. However, this theory also can not explain low temperature skating. In fact, neither of these explanations explain why ice slips even when the ice is still below zero.
