Official World Book Day £1 book

Welcome to Funny FACTopia!, a world of hilarious, weird and astonishing facts. Did you know that zebras fart when they’re startled? Or that jellyfish have no brain? Or that T.rex had eyeballs the size of apples? Or that one spacesuit costs more than a lifetime supply of pizza? Every fact is connected to the next in an ingenious trail of information. Hop from topic to topic in unexpected and amusing ways, and discover facts about crocodiles, candyfloss, kings and queens, dinosaurs, doughnuts, planets, teeth, tongues, medicine, Middle Ages and more.  And there isn’t just one trail through these pages: sometimes your path branches and you can choose to jump to a totally different (but still connected) part of the book. Where will your curiosity take you?
