"Dancing" Pint Glass Not sure if this really should go here, as I don't personally think it was anything supernatural, though I do lack an explanation for it. I'd called into a local pub for a quick drink after work a few weeks back. It was pretty empty, just myself, the barmaid, and an older guy, and we were all standing at the bar. After a while, I noticed that an empty glass on the bar top near me was "dancing." It was making short, almost deliberate looking movements, drifting forward a little way before sharply turning direction, then doing the same, seemingly moving of its own violition. I pointed it out to the barmaid, who got kind of excited and said it was the ghost of the old landlord, who "slammed doors". There were no obvious breezes, and when I got the barmaid to give me another empty glass and set it down beside the first, it sadly refused to join in the dance with its friend. When I eventually put a finger on the top of the dancing glass to stop it moving, it refused to start up again. I felt kind of bad that I'd spoiled its fun. I'm assuming it was being moved by either vibrations or tiny air currents I couldn't feel, but the glass I tried to make dance with it was unaffected, and I tried several times to "reanimate" the first without success. I'd basically like to know any suggestions to what caused it so that I can replicate the effect - it was a curiously relaxing sight.
