This is a fantastic video about how a safe can manage to be both incredibly inaccessible and very accessible at the same time – depending if you are trying to break into the safe or if you have a code at the ready. It really helped demystify the safe as a security method for me. Did you know that safes are made of steel, concrete, and Diatomaceous Earth? Do you understand how the locking mechanism of a safe works? You will after watching this video.
