Maddie heads to a bowling alley to find out how it works. She takes her special cameras and looks behind the lane to see where the pins end up and how they get put back in the right place. We also see underneath the bowling alley to find out how the ball rolls back ready for the player to take another turn. Next Maddie heads to a ribbon factory where they make lots of different types of ribbon from recycled plastic. She uses her special microscope camera to see how the tiny weft and warp yards are woven together to make a tartan ribbon.
