From a mini-catapult in a breath-mint tin to milk-jug cap blow-dart wristwatches, this handbook details how to achieve clandestine ends practically and inexpensively. In addition to creating weapons such as periscopes, bionic ears, and grappling hooks, spies-to-be will find ideas on how to hide their stash - a deck of cards, a false-bottom soda bottle, or a cereal box-brief case - and tips for target practice. Clear diagrams and instructions make construction simple, while easy-to-follow safety tips help ensure DIY builders avoid injuries. Projects include a paper throwing star, a bowler hat launcher, and a Q-pick blow gun. 256pp.
