Finding: BUSTED

Explanation: As part of their crime movie experiment extravaganza, the MythBusters unlocked the answer to whether you could open a safe simply by listening to it, as seen in so many spy flicks. Supposedly, the key to cracking a safe by sound is in listening closely for the combination that causes the lock wheels to click into place. So, equipped with an amplifying stethoscope to help detect any internal noises, Adam Savage took a crack at cracking a safe.

With his ear pressed to the souped-up stethoscope, Adam turned the safe's lock to find the combination that clicks the lock wheels into place. But after 20 minutes of trying, Adam didn't hear a single peep from the safe.

Since he was able to open the safe only after drilling a hole into the safe's locking mechanism to see how the gears turned, the only facade Adam really broke through (without the help of a power tool) was that of the busted movie myth.
