Ghost Hunters - Season 1 Episode 7
The Armory

TAPS is called to investigate an armory in New Bedford, Mass. In one room, the thermal imaging camera detects a warm mist passing in front of the lens. This is very strange, because mists are generally colder than the surrounding air. While moving along a catwalk, sound man Frank DeAngelis suddenly falls down and does not feel well enough to move for quite some time. When the video is examined, Jason sees that Franks audio equipment actually jumps up with no visible reason and hits him in the face. The video is on the TAPS site.
