Maddie is in the bathroom. She uses a special underwater camera to find out how a toilet flush works and why it makes a gurgling sound. An animation shows how the float ball and plug work together to refill the cistern after it has flushed. Next, Maddie visits a toilet factory to see how toilets are made from clay and how robots spray the toilets with a special paint to make them waterproof and shiny.
