Stone Throw This clip was taken in the Conference Room, where the group were attempting a glass divination experiment. Our photographer Stuart Cox is the man behind the camera, and as you can see he initially focuses on the table where all the members of the team have their fingers on the glass. He then pans around to where our Medium Marc Richardson is standing, with his hands clearly held against his face. At this point you can hear the sound of a stone being thrown across the room. In fact the team recovered 2 stones after the incident.
