Sydney Opera House

Towering over Sydney Harbour, the famous Opera House is one of the most recognisable and iconic buildings in the world. Richard heads Down Under, takes a stroll along the incredible structure’s roof, learns how its unique “sails” work on the same principles as a simple child’s collapsible toy, and discovers a bizarre engineering connection with a First World War gas mask.
