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 and plastic utensils - the everyday junk drawer can hold all the materials needed to create pocket-sized weaponry. Whether you're slowing dying of boredom in a stuffy office, plotting revenge on your older siblings or simply looking for a wonderful way to kill some time, this book is for you. Toy designer John Austin provides detailed, step-by-step instructions for each project, including materials and ammo lists, clear pictures, and construction tips, for mayhem-loving MacGyvers. The 35 devices include catapults, slingshots, darts, crossbows, 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. The instructions are simple so that anyone can make these wacky innovations in minutes whilst also learning about mechanics and physics in a fun, hands-on way.
