This book is invaluable!" Alexander ArmstrongChildren ask the funniest questions: Why does sweetcorn come out the same as when I ate it? Do spiders speak? Why does Daddy never win the lottery? Which is faster, a Velociraptor or a cheetah? How does the lady in the satnav know where to go? Does my goldfish know who I am? (Do you think fish have two-second memories? Find out the truth on page 94!)This book takes real children's questions gathered from primary schools across the UK and asks some of the greatest thinkers and experts of our time to give short and accessible answers. Brian Cox explores the edge of the universe, Sir David Attenborough tells us whether monkeys could ever turn into men, and Miranda Hart ponders why it's funny when someone farts.Other contributors include Bear Grylls, Sir Paul McCartney, Kate Humble, Sir Quentin Blake, Bettany Hughes, Heston Blumenthal, Alice Roberts, John Lanchester, A.
