Series 2: 4. Clock and Cutlery
Today, Maddie is finding out how clocks tell the time. She heads to a clock factory and uses a special time-lapse camera to show how the hands on the clock move around. Maddie also looks inside a battery-powered clock to see how they work. We see the tiny cogs that turn each of the hands so we can tell the time. Next, it's dinner time and Maddie visits a cutlery workshop to see how sheets of metal are made into forks. With a special microscope camera, we find out how the patterns are made using a special machine.
