Bafta-award winning presenter and technology expert Maddie Moate takes CBeebies viewers on a journey to explore the world around them. Using special cameras, she finds out how things work and how they are made.
Maddie explains how TV screens work, using a microscope camera to show us how a tiny square called a pixel can make any colour from just three coloured lights - red, blue and green. Next she visits a factory to see how carpet is made, following the journey
that wool takes and using a slow-motion camera to show us how the different coloured threads are woven together on a loom.
