Garage warriors will get a bang out of this new handbook from the author of Backyard Ballistics that shows how to build cannons and other fun things that shoot, from Wiffle ball launchers and beverage bottle bazookas to superpowered water guns and model culverins. In Ready the Cannons!, engineer William Gurstelle breaks down how to safely construct a dozen awesome artillery devices in your basic home workshops using easy-to-find household or hardware store materials. Clear instructions, diagrams, and photographs illustrate how to build projects ranging from the simple—a supersonic Ping-Pong ball shooter—to the more complex—a replica of the Napoleon Cannon. With a strong emphasis on safety, the book also gives tips on troubleshooting, tells the history of how and when the artillery devices were used, and explains the physics behind the projects. This book will be indispensable for the legions of backyard watergunners, model-rocket launchers, and fireworks fanatics who wish every day were the Fourth of July.
