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 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. aucune critique | ajouter une critique
This bestselling DIY handbook now features new and expanded projects, enabling ordinary folks to construct 16 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 match-powered rocket to the more complex tabletop catapult and the offbeat Cincinnati fire kite. The classic potato cannon has a new evil twin--the piezo-electric spud gun--and the electromagnetic pipe gun has joined the company of such favorites as the tennis ball mortar. 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. Aucune description trouvée dans une bibliothèque |

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. ( )
