Overview: In today's episode, Maddie is relaxing at home, playing games and watching television. She shows us how a television screen works using millions of tiny squares called pixels. Using her special microscope camera, Maddie shows us how a pixel can make any colour from just three coloured lights - red, blue and green. Next she visits a factory where carpet is made. Maddie follows the journey that wool takes, from shearing a sheep to going through the factory, to end up in the carpets we have at home. Maddie uses her special slow-motion camera to show us how the different coloured threads are woven together on a loom to make a carpet.
