A fascinating flap book packed with interesting information about how lots of things work. Discover the inner workings of cars and boats, farm and building site machines, everyday household items including vacuum cleaners, computers and fridges, and much more. Each of the seven double page spreads has several flaps to lift, to see inside a subject and understand how it works. Clear, easy to follow text introduces young readers to subjects such as electricity, simple machines and natural forces. Each topic is brought to life by fun, lively illustrations by Stefano Tognetti.
