An encyclopaedia of mind-bogglingly random facts that will lodge in your brain and refuse to leave.

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 rollercoaster can cure kidney stones?

In this compendium of obscure facts readers will be treated to baffling knowledge they would never learn at school. Broken into chapters including geography, space, and history, a team of experts has scoured the world to find the silliest and most pointless facts that it has to offer.

Accompanied by hilarious illustrations, kids will meet the prehistoric camel with no humps, the tortoises that went to the Moon (and came back again), and dancing cave people. They will learn crucial life skills like how to walk on custard and how to unboil an egg by spinning it 5,000 times a minute. And they will read the heartwarming story of a court jester called Roland the Farter – can you guess what his special skill was?

(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!)
