> A new model of the slipperiness of ice suggests that a layer of
> disordered ice forms underneath a sliding object. The model was
> developed by Bo Persson of Forschungszentrum Jülich in Germany, and
> it could ultimately find practical application in helping to develop
> better skis, or improve traction in winter footwear or tyres.

> Ice is, counterintuitively, not inherently slippery. Instead, it
> becomes so through the formation of a thin layer of meltwater on its
> surface. This liquid water can be created either by frictional heat
> or through a phase transition called premelting, which can occur at
> temperatures below the freezing point of water.
