Book Description
Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar, the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey—ancient artillery devices known commonly as catapults. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. Instructions and diagrams illustrate how to build seven authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier John Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle.

Book Description
A man’s home is his castle, or so the saying goes, but could it withstand an attack by Attila and the Huns, Ragnar and the Vikings, Alexander and the Greeks, Genghis Khan and the Mongols, or Tamerlane and the Tartars? Backyard Ballistics author William Gurstelle poses this fascinating question to modern-day garage warriors and shows them how to build an arsenal of ancient artillery and fortifications aimed at withstanding these invading hordes. Each chapter introduces a new bad actor in the history of warfare, details his conquests, and features weapons and fortifications to defend against him and his minions. Clear step-by-step instructions, diagrams, and photographs show how to build a dozen projects, including “Da Vinci’s Catapult,” “Carpini’s Crossbow,” a “Crusader-Proof Moat,” “Alexander’s Tortoise,” and the “Cheval-de-frise.” With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind many of the projects, and shows where to buy the materials. By the time they’ve reached the last page, at-home defenders everywhere will have succeeded in creating a fully fortified home.

Book Description
We’ve come a long way from the Peashooter Era: with the advent of modern household products and office supplies—binder clips, clothespins, rubber bands, ballpoint pens, toothpicks, paper clips, plastic utensils, and (of course) matches and barbeque lighters—troublemakers of all stripes have the components needed to build an impressive, if somewhat miniaturized, arsenal. Toy designer John Austin provides detailed, step-by-step instructions for each project, including materials and ammo lists, clear diagrams, and construction tips, for mayhem-loving MacGyvers. The 35 devices include catapults, slingshots, minibombs, darts, and combustion shooters. Build a tiny trebuchet from paper clips and a D-cell battery. Wrap a penny in a string of paper caps to create a surprisingly impressive “bomb.” Several of the projects even include variations where combatants mount laser pointer sights to their shooters to increase their accuracy. Finally, once you’ve built your armory, the author provides plans for a Top Secret Concealing Book to hide your stash, as well as targets for shooting practice. Never let your personal space go undefended again!

Book Description
Painter, architect, scientist, inventor—Leonardo da Vinci ranks as history's consummate innovator. Consumed with a boundless desire for knowledge, he investigated technical challenges that were hundreds of years ahead of his time. The power of flight was a particular source of fascination for him, and his close studies of bird anatomy and movement informed his development of the ornithopter — a winged, human-powered aircraft. With Leonardo's da Vinci's Flying Machine, you can create a fully working model of the inventor's amazing creation. This self-contained model kit features a 48-page book with details from Leonardo's notebooks plus full-color, easily joined components. Once assembled, the wings flap by turning a crank. Like the prototype, your model won't actually fly, but you'll have an amazing replica of one of the Renaissance genius's most famous futuristic inventions.
