We are The Paranormal Adventurers located in St Augustine, Fl. This video was taken during an investigation of The Spanish Military Hospital Museum. The girl standing up is looking for the source of a 'vibrating' sound. The girl seated closest to the camera is using a K-2 meter (EMF) for the first time. We gave instructions for use prior to seating them in the room. Watch the camera glitches, they are not normal. When the girl holding the K-2 asks "Is this supposed to vibrate?". "NO!". That's when the K-2 gets tossed and the mass exit occurs!
