This book tells the story of how a child managed to weigh an elephant. Cao Cao, a high-ranking official in the late Eastern Han Dynasty, got a gift: an elephant. He wondered how heavy the elephant was, so he asked his subordinates to think of a way to weigh it. No one knew how to do it. Cao Cao’s youngest son, Cao Chong, a child around the age of five or six, came up with an idea and managed to weigh the elephant using the Principle of Buoyancy.
