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
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
What happens if you water plants with juice? Where can you find bacteria in your house? Is slug slime as strong as a glue stick? How would your child find the answers to these questions? In The Curious Kid's Science Book, your child will learn to design his or her own science investigations to determine the answers! Children will learn to ask their own scientific questions, discover value in failed experiments, and — most importantly — have a blast with science. The 100+ hands-on activities in the book use household items to playfully teach important science, technology, engineering, and math skills. Each creative activity includes age-appropriate explanations and (when possible) real life applications of the concepts covered. Adding science to your at-home schedule will make a positive impact on your child's learning. Just one experiment a week will help build children's confidence and excitement about the sciences, boost success in the classroom, and give them the tools to design and execute their own science fair projects.

From the creators of the bestseller CLOUDY WITH A CHANCE OF MEATBALLS comes another zany, laugh-out-loud picture book! The Town of Left and the Town of Right are separated by a dotted yellow line, and no one on either side can remember how things got to be this way!

Unfortunately, the only ammunition they have around is marshmallows -- 50,000 boxes worth! So begins the Marshmallow Incident, a tale of Left and Right, and Right and Wrong, with an incredibly silly but delicious dose of Mallo-Puffs and Marsh-Pillows thrown in. Kids will read it once and then beg for s'more!

Book Description
"My son at 10yo (90-lbs) is highly coach-able. I taught him the system in February and he hit well during the season but could only hit the ball around 180'. Then all of a sudden around June he started killing the ball. He was hitting home runs every game and hit a ball at least 250-feet" - Michael Parillo (via email) Sick of struggling to help hitters drive the ball hard with more consistency? Dramatically increase power without sacrificing swing quality. Literally thousands of coaches across the nation are getting predictably positive results with hitters using the CLS system. How? By applying human movement principles validated by REAL science to hitting a ball, and NOT "bro-science." THIS STEP-BY-STEP GUIDE TO CONSISTENT POWER TEACHES: How to master a handful of human movement principles, so you can slice the "teach hitting" learning curve in half. How to effectively load the body, so your hitters can optimize their batted ball distance potential. How elite-hitters are revealing ways to hit balls with High-Exit-Speeds, swing after swing, using three elements a 4-year-old can understand. Why 'loading and exploding the hips' is bad for lower back, and how to teach hitters a highly effective but SAFE swing. THE NEW EXPANDED EDITION INCLUDES: 'How to practice' section at end of each movement principle Chapter. How to train a 2-year-old to hit a moving ball (proof that NOT only elite hitters can be taught these movements). Why pitchers are taught to pitch around ineffective swing paths, and how to turn their weapon against them. Why coaches MUST focus their hitters' efforts on targeting and elevating pitches low in the zone. How to teach timing and get hitters on-time more often in games.
