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.

It's bedtime and Maddie is finding out about different things we sleep on and in! At a campsite she uses a special thermal camera to show how the layers in a sleeping bag work by trapping warm air inside to keep us warm. Next, Maddie visits a mattress factory to see how a mattress is made from layers of foam and material, a bit like a giant sandwich! She uses a special camera to see the tiny holes in the sponge that make the mattress nice and soft for us to lie on.
