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.
