Heard about the lizard that shoots blood from its eyes? Or the ancient Romans who used wee as mouthwash? Did you know that going on a roller-coaster can cure kidney stones? In this compendium of obscure facts readers will be treated to more examples of baffling knowledge. Broken into chapters including geography, space, and history, a team of experts has hunted down the silliest and most pointless facts that the world has to offer (SPOILER: the information in this book isn't really useless. It will inspire, shock, and amuse the reader -and maybe spark an interest that will last a lifetime. It just won't help you with any exams!)
