玩具设计师John Austin为喜欢喜欢搞破坏的百战天龙们提供了每一个项目的详细和手把手的指导，包括材料和弹药清单、清晰的图片、组装建议。

35套装置包括弹射器、飞镖、十字弓和燃烧枪。用回形针和D型电池建一个小型投石机。将一枚一美分硬币包在一串纸帽中，做出一个令人叹为观止的“炸弹”。有几个项目甚至包括一些变体，战士们将激光笔瞄准器安装在枪上面以提高准确率。

指导非常简单，这样每个人都能在几分钟内做出这些古怪的装置，同时用一种有趣、实操的方式学习机械学和物理学。

We've come a long way from the Peashooter Era: with the advent of modern household products and office supplies - foldback 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.
