Simon Tierney explores the hidden histories of ordinary things, from the toothbrush to the traffic light and the barbeque to the bed. Based on the popular weekly series on Newstalk Radio's Moncrieff Show, Stuff that Changed the World offers a fascinating and humorous look at the things around us we take for granted. Discover why men wore high heels before women did, how Queen Elizabeth I owned the world's first flushing toilet and find out if early staplers really required a mallet to operate! The book takes readers on a journey through a kaleidoscope of social history to find the extraordinary stories behind the most ordinary things.
