If you've found yourself stuck in an office, home office, or a cubicle working on some dreadfully boring assignment, or have no assignments coming your way, or that guy Nick from the neighboring cubicle is bugging the living daylights out of you, then this book is for you. It gives very clear graphically intuitive steps for building simple weapons out of materials or supplies that you can find in most offices. Even the ones that are not readily available can probably be purchased from the nearby convenience store during a lunch break. It is absolutely incredible what sorts of weapons you will be able to construct using these simple instructions - coin shooter, tube launcher, clip crossbow, hanger slingshot, paper darts, CD-spindle catapult, match rockets, ping-pong zooka, water bomb, etc. It is assumed that you have at least some dexterity and skill constructing mechanical contraptions; otherwise you'll be stuck throwing paper balls at your coworkers, you tool! Some of the contraptions in this collection are actually dangerous, so proceed with caution when using them. I take no responsibility for any injuries that may result from the use of contraptions that are described in the book. The ones that I've made I only use when no one is around. Just in case.
