Guns and Goldmines

S1 E7: What does a ship steering wheel have to do with the Colt revolver? What 400-year-old secret is the cymbal hiding? What is the link between the San Francisco earthquake of 1906 and Bank of America? And what is the untold story of the creation of Monopoly? We explore four multimillion-dollar inventions, and meet the people who changed the world with the barrel of a gun, an ancient riddle, selfless customer service, and a lucky roll of the dice.
