Kundenrezensionen
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.
One of the unique things about this book, as compared to other similar books, is the emphasis on both safety and history. Safety is important for obvious reasons. But most readers are enthusiasts about this sort of stuff, and the history lessons are exciting.
My only complaint is that there is no room in this book for any sort of modification to the designs. For example, there are formulas that can be used to determine the maximum chamber size for a PVC-constructed potato gun, and with this, you can design your own potato gun in relative safety. Unfortunately, the author insists that you stick strictly to his designs. This appears to be an effort to ensure that all of the "toys" created with his book are safe, so that's only a minor complaint.
Can't wait to start lobbing tennis balls!
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!
