Combining two fantastic authors this brilliant flip-book will satisfy on both sides. Glenn Murphy's very funny question and answer book will solve some of life's great unknowns: what are scabs for and is it OK to pick them? How loud can you burp? Could we use animal poo in power stations to make electricity? And of course, Do Bugs Have Bottoms? Endorsed and checked by the Science Museum. Then flip over and let Jiggy McCue show you what really happened at the dawn of mankind in this fantastically funny caveman caper. Jiggy should have known a school trip to the Museum of Natural History with the class dimwit, Eejit Atkins, wouldn't go to plan. But when he and Eejit end up travelling back in time to primitive earth, things get a whole lot more bizarre...
