Many of the events in the Winter Olympics involve some sort of sliding or slipping on ice—in a skillful, controlled way. Those moves often seem effortless, but the physics behind what makes them possible is messy. For centuries, scientists have been trying to figure out why ice is slippery. In this episode of Science Quickly, host Kendra Pierre-Louis laces up her skates to explore the slippery truth behind that deceptively simple question. She’s joined by science journalist Paulina Rowińska and physicists Daniel Bonn and Martin Müser, who take us through various competing theories and explain how we may finally have a winner.
