Remember those old movies, where the burglar
picked the safe, listening through a stethoscope?
Well, out of curiosity, I bought a stethoscope,
and tried it on my gym locker, a standard Master combination lock. I
went slowly through the
numbers, and heard..... nothing. No telltale as
I hit the combination.
So what's it all about, anybody know?
