Today Maddie is learning about metal, and how it can be recycled and used again. Maddie visits a recycling centre where they recycle metal from old cars. She uses her special cameras to help us see how the gigantic crab cranes pick up, move and crush the cars into small pieces. The cranes are so big that they make the real cars look like toys! We also find out how a machine uses clever magnets to pick out the metal from other materials in the car like glass, rubber and cloth.\n\nNext, she visits a road sign factory to learn how they are made. She finds out about the different shapes of road signs and what they mean. Then Maddie uses her special time-lapse camera to see the designs as they are printed out on sheets of metal. Maddie finds out that they are covered in a reflective material that helps cars see the signs when it's dark.
