| Ordinary folks can construct 13 awesome ballistic devices in their garage or basement workshops using inexpensive household or hardware store materials and this step-by-step guide. Clear instructions, diagrams, and photographs show how to build projects ranging from the simple-a match-powered rocket-to the more complex-a scale-model, table-top catapult-to the offbeat-a 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.

There are some cool projects here, especially for people that like to make a lot of noise. BOOM!!

By doing these projects with one's children one can teach them
engineering, mechanical, planning and fabrication skills as well as how to see through a project that may take a few days instead of 15 minutes. Their interest in the projects will
be maintained by the fascinating science as well as the impressive results.

I found this book to be quite informative and helpful on building many fun ballistic devices. The chapters on the spud gun and back porch rocketry were probably my favorites. For anyone who grew up constructing innovative (but highly unsafe) projectile launchers and wants to create something the neighbors can appreciate, this book is for you!
I would also like to emphasize that GIRLS, as well as boys, can and will enjoy this book.

This book is a lot of fun. The projects are things that you can do safely, and that kids really like. I just wish the author had put a little more work into it. Some of the history doesn't seem accurate, and the physics should be explained more clearly. More effort on content and less on strange facts would help.
Building the onager (torsion catapult), I had to change most of the dimensions. The book calls for 1"x1" wood, but that's hard to find. 1x2 (nominal) is easy to find, but is 3/4" by 1 1/2". A book for quick projects should use 1x2s, not some mythical 1" square lumber. The drawings were incomplete. Between the drawings and the photo it was possible to get the whole thing together, but I had to change most of the dimensions. Why he uses 1/8" dowel is beyond me. Even 3/16" broke too easily.
Overall, interesting and certainly fun, but I wish it were done more carefully.
