used this morning so not wet
nowhere near the edge last time I realised it was still there (would not have placed it near edge of counter anyway because of DC)
not knocked or moved by vibrations/ noise etc
looked up as it toppled gracefully over the edge about three feet from where I was
could swear I saw it shuffle as it wasnt the smash that I noticed, I watched it tumble silently from the top so something must have caught my eye (ie: movement)
any explanations? spooky or otherwise all gratefully received
