About this item

Create projects and projectiles that will fly, float, launch, or roll on their own power with Rubber Band Engineer!So many of the world's most inventive minds, from Ben Franklin to Steve Jobs, were lifelong tinkerers. Their joy in the process is evident in the originality of their work. Maybe that's why so many adults never lose their fondness for the inventive toys they made as kids -- tinkering was fun, and still is, so why stop?Author and Engineer Lance Akiyama shows you how to create twenty-five gadgets of his own design. Most are propelled by rubber bands, while some use levers or gravity for thrust. The combination of simplicity and creativity while using ordinary objects makes these projects so extraordinary! With a wide range of project types, this book takes you beyond the basic rubber band launcher.
