In Friction, two young Islanders, Olive and Troy, are delivering mail with a mammoth-drawn wagon when they learn how important the force of friction is as they attempt to slow down! Applying what they discover about friction, Olive and Troy test a variety of brakes, trying to find the type just right for them. Even with proper brakes, it does take some time to come to a stop, though. Young Troy and Olive find this out as they join their two delivery mammoths for an unscheduled bath after a foiled attempt to stop quickly! Part of a multi-volume series, The Way Things Work is based on the best-selling book by David Macaulay.
