DIY: in Prison Answered
Limited resources? Hiding from authority? No, not a young DIY-er with a low budget and strict parents, but prison inmates trying to get out. Take a look at this collection of photographs by Marc Steinmetz showcasing creative escape tools crafted by German prisoners while in jail. While many of them were confiscated before completion or implementation, a handful of them were used successfully to break out of jail.
While I in no way condone these actions, you've got to admit some of these are creative use of available resources. Plus, if Instructables ever ran an Escaping from Prison contest (sponsored by Alcatraz tourism, anyone?), we'd all be up against some pretty stiff competition.
