Maddie is visiting a supermarket, where she finds out what barcodes are and how they work. At the checkout, we learn how an infrared scanner reads barcodes to find out what items we are buying and how much they cost. Maddie uses a special camera to see how the right items in the stock room get to the right shelves in the supermarket. Next, Maddie heads to a factory to see how fishcakes are made.
