Weatherwatch: The surprisingly complex science of ice skating | Science
Ice skating is counterintuitive: why should a narrow blade make it easier to slide over the ice? The science is surprisingly complex, but unscientific people worked out the practical application a long time ago.William FitzStephen described how Londoners entertained themselves in freezing conditions in 1173: “Crowds of young men go out to play on the ice. Some of them fit shinbones of cattle on their feet, tying them round their ankles … and are carried along as fast as a flying bird.”Some of these early bone skates are on display at the Museum of London.The standard explanation – that the pressure exerted on a small surface area melts the ice creating a slippery layer of water – is only part of the story. Pressure only slightly lowers the melting point, most of the real work is done by fr...
