In this episode, Maddie is relaxing at home. She finds out what happens to our bodies when we go to sleep at night. Using a special sleep monitor, Maddie shows us that our bodies do not simply switch off but are in fact doing lots of important things while we sleep. She discovers how our breathing and heart rate slow down and how sometimes our eyes flicker. Next she visits a factory where sofas are made . Maddie follows the journey the wood takes: from cutting the planks, to building the frame, to making the upholstery to cover it. Maddie puts her special slow-motion camera inside a cushion to show us how a special machine blasts the feathers into the cushions at incredible speeds.
