In today's episode, Maddie is having fun. She takes to the dance floor to show us how a disco ball works. We learn how light is reflected in lots of different ways, and a special camera on a long pole shows us how the tiny mirrors reflect light around a room. Next, Maddie heads to a factory where they make jigsaw puzzles from wood. Maddie's head camera gives us a special view when the puzzles are cut using an electric saw.
