This presentation will introduce two powerful, non-destructive safe opening techniques. The first "Dial B For BackDialing," will trace the history of backdialing all the way from Richard Feynman working on the atomic bomb (and opening safes) in the 1940's, to today. This presentation will show how mechanical safes have changed since Feynman's time, but how most are still vulnerable to both his method and the simpler Nascar(tm) technique. The next part of the presentation, "Spike the Wonder Safe" will demonstrate how to defeat the two locking mechanisms of a popular office safe using just an ink pen and a battery, all in under two minutes.
