Mysterious Moving Egyptian Statue Has Experts Stumped [Video]

Here's a head scratcher for you: an ancient Egyptian statue, housed in a sealed glass case in England at the Manchester Museum has started mysteriously revolving in the case.  The statue depicts Neb-senu which, according the museum's curator, Campbell Price, is made from serpentine and is likely an Egyptian official with "priestly duties".   On the back of the statue are hieroglyphs spelling out, "bread, beer and beef," a "prayer for offerings for the spirit of the man".  The 10 inch tall statue has been on display at this museum for about 80 years but only started moving recently.  Video footage shows the statue only moving during the day and it always ends up with it's back turned to on-lookers.  Check out the movement below.

Theories anyone?  Some fear it a curse of the Pharoahs while others believe that subtle vibrations are making the statue rotate.  Perhaps it's a hoax?  If so, it's very clever since the case is locked up tight.  My theory is that the statue just wants people to bring him beer, bread, and beef like it says on his back.  Who wouldn't want that?  Or maybe it's just the night watchman who wants that?  Either way, people should try leaving those things and see what happens.
