Bosses at Manchester Museum have been left puzzled by the mystery of an ancient Egyptian statuette which seems to turn itself around 180 degrees in its display case. The 10-inch tall statue of Neb-Sanu, which dates back to 1800 BC, was found in a mummy's tomb and has been at the Museum for eighty years.
And now a time-lapse video (you can view the video at the link) clearly shows it turning on its axis during the day, apparently of its own volition. During the night, however, it remains still.
