Book Description
Wilson provides photos of the building process, detailed and updated plans, plus construction information on ballistas, onagers and trebuchets. You will aso find information on catapult web sites and how to be included in some of the catapult contests around the country. Also included is some interesting catapult history, its strength and weakness as a weapon, and what it was that led to its demise as a functional war machine. There's no question that warriors have found more efficient means of lobbing projectiles at enemies, real and imagined, but has it ever been as much fun?

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
Calling all pumpkin chuckers, wannabe marauders, and tinkerers of all ages! Flinging things and playing at defending your own castle has never been more fun. 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. Updated and improved instructions and diagrams illustrate how to build 10 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. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. 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 Jon Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle. For the legions of Tolkien fans, budding backyard warriors, and engineering wizards, this book is a must-have.

Book Description
Kids will learn how things they encounter every day operate by building their own models with this hands-on activity book. Projects include building a working model of the human hand's muscles, bones, and tendons using drinking straws, tape, and string; using a pair of two-liter bottles and a length of rubber tubing to learn how a toilet flushes; and discovering how musical instruments make sounds by fashioning a harmonica, saxophone, drum, flute, or oboe. All devices are designed to use recycled or nearly free materials and common tools. Kids are encouraged to modify and improve the designs, or create an entirely new device using the concepts explored. Each project includes materials and tools lists, step-by-step instructions with photographs, a summary of the science concept demonstrated, and follow-up questions to gauge student understanding for use in the classroom.

Book Description
A treehouse is a wonderful idea, but how in the name of creation do you actually build one? In this delightfully illustrated handbook, David Stiles, the unofficial world grandmaster of the treehouse, shows how. Not assuming anything about the treehouse builder, Stiles starts with the basics: how to nail, how to buy wood, what kind of screws and nails to use. Then it's on to an A-frame design so simple that it can be built in a weekend out of four sheets of plywood, followed by lean-tos, a tree hut, and a Tarzan-style jungle hideaway. There are also forts of every description, including a 21-foot-tall lookout tower modeled on one George Washington built to keep an eye on the redcoats. Stiles also adds a design for a snowball catapult, an igloo and even a Nerf-loaded cannon. Written for children, with an adult peeking over their shoulder, Stiles's TREEHOUSES, HUTS, & FORTS is a dreamer's handbook, offering practical results.
