Do you ever wonder where the stuff around you all came from? No, not from eBay. I mean, who had the amazing idea of making a mobile phone or the annoying idea of building a school? For example, did you know that Velcro was invented by a dog and WiFi by a movie star? (Spoiler alert - it wasn't Zendaya.) In the fourth laugh-out-loud book from Adam Kay and Henry Paker, you'll learn all about the coolest, grossest and most ridiculous inventions in the world. You'll meet the queen who used the first ever toilet, learn why margarine used to be full of maggots and find out why Ancient Greeks wiped their bums on dinner plates. Oh, and hopefully some slightly more useful facts as well... An A to Kay to Z of the random, ridiculous and revolutionary inventions that changed our lives. (And some that definitely didn't . . .)

KAY'S BRILLIANT BRAINS is a mini book written and illustrated for World Book Day 2023 by the record-breaking Adam Kay and Henry Paker. It's a hilarious celebration of the world's most ingenious geniuses and all that their brilliant brains achieved. One hundred billion people have lived on earth. Unfortunately, this book would be too heavy if it talked about them all, so it's about ten of them. You'll meet Amelia Earhart, who flew across a huge ocean in a tiny plane, back in the days when planes were basically made out of old bits of wood (and worst of all, they didn't have in-flight movies) and Thomas Edison, who invented light bulbs and movie cameras (but only went to school until he was twelve). Plus a whole bunch more other brilliant people with brilliant brains who woke up one day and thought 'Oh, I've got an idea . . . !' and changed the world forever.
