2125. A bomb training briefcase, it was used in the 1980s to show several ways a bomb could be triggered. OSI Technical Services installed electronic switches to detonate the "bomb" under various circumstances. If the lid was opened, a light-sensitive photocell set off the device. X-raying the briefcase activated a brass sensor, and a mercury-filled switch set off the bomb if the case was moved. Touch sensors on the latches also set it off. A noise from the black speaker indicated an "explosion."
