Exploding with fan-favorite characters and jokes from The   Big Bang Theory , this picture book is perfect for readers of all ages, including the hit TV show's biggest fans and the smallest science enthusiasts!   Leonard, Sheldon, and their super smart friends are competing in the Siebert Science Fair! The first prize? An appearance on everyone’s favorite show, Professor Proton ! Who will make their big debut? Will it be Howard and Raj for their rocket? Amy and Bernadette for their research on the human brain? Leonard for his laser? Or Sheldon for one of his four projects—maybe his comparison of soft kitty and warm kitty?   When a scientific catastrophe disrupts the event and jeopardizes everyone’s chances at stardom, though, a solution comes from a new and different kind of friend.
