You sit on it every day, but how much do you really know about your toilet? Discover the history of pooing and weeing in this frankly disgusting non-fiction book. Authors Katie Nelson and Olivia Meikle have scoured the toilet bowls and sewers of the world to find out how humans have done their business throughout history. Prepare to be revolted by a fossilised Viking turd discovered by archaeologists, the Mongol catapult used to fling smelly poo at their enemies, and the reason ancient Romans used wee to wash their clothes. Featuring hilarious illustrations by Ella Kasperowicz, it's a history book like no other!
