Backyard Ballistics is a book that explores physics through DIY projects. The main focus is on making the projects. The underlying physics is explained in the book along with step-by-step instructions on building these items. It also has troubleshooting points with things that can go wrong and how to combat those things. On the other hand, the book has few equations and all of the units are imperial rather than metric. However, in this case, it might be better for all involved. Engineers are practical. It isn’t necessary to go into SI units if the audience is American. In that same vein, it wasn’t necessary to put a fluid dynamics equation in the book if you are just making a model rocket.

William Gurstelle goes in-depth on each project. He brings up the materials needed and covers the history of the physics involved as well. For example, when talking about building a Sublimator, Gurstelle goes into the history of making Dry Ice. Each project has a timeline talking about how that invention was developed.

The only unfortunate part about writing a review on this is that there isn’t really a lot to say on this book. Although the book does touch on the theoretical the main focus is on practical projects and things to make. If you enjoy making things or if that is how you learn, then you will appreciate the hands-on approach. ( )

I bought this book to use in an after school science enrichment class I teach. It did not disappoint, the kids thought all my exploding stuff was great. Along the way they also learned terms like exothermic and velocity. Pretty decent for elementary school. Plus? Now I'm the coolest mom in school. :-D ( )

A manual that shows how to make fun shooting and flammable things such as a potato cannon, a paper match rocket and a Cincinnati fire kite. Far beyond the ballistic fun to be had are the opportunities to explore physics through the scientific method. The author explains the science behind each project and provides further thought for study. Includes sidebar stories about relevant scientists and emphasis on safety.

This book rules. I am a grown-ass woman and I'll be doing some of these experiments. I don't have kids. It just sounds like fun. ( )

This book is not politically correct, in an era in which school science experiments have been tamed to the point that there is little possibility that the teacher will kill or maim him/herself. William Gurstelle, an engineer who has been collecting plans for devices that will throw stuff fast and far, is careful to emphasize the hazards implicit in shooting potatoes or water balloons the length of a football field, or launching flaming newspaper (Cincinnati fire kite) into the sky. Youngsters would need lots of adult supervision when making or using these devices, but any budding engineer would thrill to see them in action. ( )

Take a risk and have some fun. This book give details on how to make some fun and slightly dangerous projects safely. I remember making a few of these as a kid. ( )

Some interesting experiments and easy to follow instructions. ( )

Fun, easy-to-build devices that go BOOM and toss objects moderate distances. Good safety tips, but an adult should generally be involved in these experiments! ( )
