In today's episode, Maddie is finding out about things that go up and down. She shows us how a lift works, when it carries people up and down between floors of a building. With the help of an engineer and her special cameras, Maddie show us how the gears and weights are controlled by a computer. Next, it's time for lift-off as Maddie heads to a space museum. We see how a spacesuit is made from lots of different layers of special materials to keep astronauts safe when they are working in space, and Maddie uses her special thermal camera to see how the suit keeps astronauts warm.
