Backyard Ballistics: Build Potato Cannons, Paper Match Rockets, Cincinnati Fire Kites, Tennis Ball Mortars, and More Dynamite Devices

The highlight of this book is the chapter on the venerated potato cannon (a.k.a. spud gun). The author presents a simple yet effective design and gives detailed instructions on how to construct it. I have seen a number of designs on the web, and I prefer this for it parsimonious design. I have "launched" a number of spuds with this cannon, and am perfectly pleased with its operation.

Other projects include back porch rocketry (the paper match rocket, the hydro pump rocket, and the pneumatic missile), the Cincinnati fire kite, the Greek fire and the catapult, the tennis ball mortar, the flinger, Pnewton's petard, the dry cleaning bag balloon, the carbide cannon, and the ballistic pendulum.

The book is clearly written and illustrated (with drawings and black and white photographis). It contains a number of history vignettes along with some illustrations of ancient weapons. The remaining chapter includes some ideas for further study.

While I highly recommend this book, please note that some of these projects (most notably the potato gun) are illegal in some states. In that case, this book would be for "reference" only.


Things that go "Boom" in the Night   March 5, 2003

What a wonderful boys book--boys from 9 to 90 will get a bang out of these projects. The author presents enough safety information to be reasonable, and mixes in scientific explanations, a bit of math, and interesting anectdotes that take us back into the history of ballistics. But most of all, he presents details plans and parts lists (including sources for hard to find parts) to build things that shoot up into the air, things that go "BOOM," and other cool stuff like fire kites.

Many of the projects described here are also well documented on the internet. But most internet postings have little to say about safety, science, or history. Using this book as a starting point, and the internet as a resource to expand the ideas, could lead one to develop a truly interesting ballistic arsenal indeed!!

Before we had homeland security to worry about, this might have been a good source book for a science fair. Now, it just might be a great way to spend a lifetime behind bars. But, if you're in touch with your inner Goddard, von Braun, or just love the idea of a tennis ball mortar ... then this is the book for you!


Parents, Dont be scared   April 27, 2003

This is a great book. Just from skimming through it you can tell that a lot of thought and precaution went into it's construction. Parents may be scared seeing a book like this in the hands of their child, but don't be frightened. Most of the projects in here are pretty innocuous and saftey is paramount. The book and author STRESS proper precautions and advise saftey gear for any dangerous experiments. If you have a kid who has been playing with fire, been showing a disturbing interest in explosives or such, then buy them this book and do these projects with them! It will give kids a productive, educational and supervised outlet for these curiosities and fascinations and will give you a chance to teach them a bit about physics and further bond with them. Some young pyros grow into arsonists, others grow into firemen and physicists... you make the choice! Instead of punishing them and trying to curb their interest in such things, channel this energy into something positive.

From the perspective of an adult or adolesent this book is still great. Fun projects and lots of information make for a fun read, and an even more fun summer project. Science teachers and the like will love this book as some of these projects could prove wonderful classroom demonstrations to aid in teaching and more importantly, in getting kids' attention and perhaps sparking an interest.

Great book. more stuff like this might help the curb effects of all the negative stuff out there like the Anarchist's Cookbook and all those [explosive] websites.

A big five stars!

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.


a great yboyysy book for boys of any age and either gender   September 13, 2001

-- a great "boy's" book for boys of any age and either gender. The author complements his assortment of projects that throw things (like potatoes or tennis balls) with touches of physics and history. It is well written so that it is entertaining even if you don't intend to actually build the projects. The directions and drawings are clear so that the steps of construction for the various devices are clear. Great entertainment!
