Backyard Ballistics  |  Whoosh Boom Splat  |  Building Bots
The Art of the Catapult  |  Adventures from the Technology Underground

What happens when you duct-tape a couple of potato chip tubes together, then add an energy source, a tennis ball, and a match? Well, not much - unless you know the secret to building the fabled tennis ball mortar. This step-by-step guide enables ordinary folks to construct 13 awesome ballistic devices in their garage or basement workshops using inexpensive household or hardware store materials.

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.

This book will be indispensable for the legions of backyard toy-rocket launchers and fireworks fanatics who wish every day was the Fourth of July.
