No locker or bike is safe once you learn this trick! This week, we're back to learning crime with escape-artist and illusionist Daniel Martin. Our target? Combination and keyed padlocks. These padlocks are everywhere: on bikes, lockers, trailers, and more, and you won't believe how easy they are to open without any kind of key or proper code. The secret (as Dan explains) is in using a shim, much like the ones explained in the handcuffs episode. Combination lock shims are dirt cheap, and very effective, but most amazing of all, you can make one yourself ABSOLUTELY FREE!
