Reviews

"Fun and potentially dangerous, this is sure to be a hit at most public libraries. Recommended. Bring your own safety goggles." -- Library Journal "A great primer for the would-be engineer, and a wonderful chance for bonding among like-minded parents and children...Great fun!" -- Courier-Journal (Louisville, KY) "How is it possible not to love a book with chapter titles like 'Back Porch Rocketry' and 'Greek Fire and the Catapult?' I devoured this prodigious account of all things explosive." --Homer Hickam, author of Rocket Boys "Would-be rocketeers, take note: Engineer William Gurstelle has written a book for you." -- Chicago Tribune "If you want to make a potato souffle, pick up a book by Julia Child. If you want to decorate your holiday cards with hand-cut potato stamps, look to a Martha Stewart manual. If, however, you'd like to launch a potato in a blazing fireball of combusting hairspray from a PVC pipe, your best source is Backyard Ballistics , by William Gurstelle." -- Time Out New York "Your inner boy will get a bang out of these 13 devices to build and shoot in your own back yard, some of them noisy enough to legally perk up a 4th of July." -- Dallas Morning News "How is it possible not to love a book with chapter titles like 'Back Porch Rocketry' and 'Greek Fire and the Catapult?' I devoured this prodigious account of all things explosive." --Homer Hickam, author of Rocket Boys
