Patents is covered in bubble wrap, one of man's more ingenious creations. It includes dozens of notable patents, from the airplane, brassiere, chain saw, and fire hydrant to the Internet, parachute, plunger, and zipper. The purpose of each device is explained in accessible language, along with background about the inventor, interesting sidebars and history, and an excerpt from the original patent application. The artwork throughout includes photos of original models and patent diagrams created by the inventors themselves, annotated to show exactly how each item works.
