Backyard Ballistics by engineer William Gurstelle is a guide on how to make 16 ballistic devices at home, from potato cannons to Cincinnati fire kites. The expanded 2nd Edition goes on sale September 1.
Clear instructions, diagrams, and photographs show how to build projects ranging from the simple match-powered rocket to the more complex scale model, table-top catapult to the offbeat tennis ball cannon. With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind the projects, and profiles scientists and extraordinary experimenters such as Alfred Nobel, Robert Goddard, and Isaac Newton
