Story summary

Researchers are examining why ice is slippery, focusing on a thin watery layer on the surface.
James Thomson, a physicist, proposed that the pressure from a person's weight lowers the melting point of ice, creating water.
Bowden and Hughes, researchers, propose friction generates heat and melts ice, with critics saying the explanation remains incomplete.
A fourth hypothesis was introduced recently, with scientists still lacking consensus.
