Do you have some crazy inventions up your sleeve?

This book is jam-packed with Andrew Rae’s amazing drawings showing all sorts of real inventions that seem too weird to work. How about a dog umbrella? A submarine that looks like a plane… or even a shark. A swimming machine where you don’t get wet? A car wash for people? Someone has even made a device to charge your phone using a hamster!

There is plenty of inspiration to get kids’ minds going, and plenty of room to add their own crazy inventions to the mix. They can design the best beach buggy ever, create a brand new sweet to share with the world, or even draw a transformer dinosaur! Includes a patent certificate for their very own crazy invention.
