In this episode, it is washing day! First, Maddie visits a washing machine repair centre to find out how washing machines work. She discovers how water gets into the drum through tiny holes and how a belt at the back spins the drum around very fast. Maddie puts her special camera inside the drum, and we see how the water and detergent are swished around to get a T-shirt clean inside.

Next, Maddie goes to a jeans workshop and uses her special microscopic camera to discover how the weave in denim material makes it extremely strong. We also learn how lots of different shapes of materials are cut out and stitched together to make a pair of jeans. Show less
