Egyptian statuette turns around by itself in museum display case

A Egyptian statuette has suddenly began turning itself around in its display case at a UK Museum, but no one is certain as to how or why.  It happens slowly throughout the day.  A time lapse video of the statuette turning around was uploaded to YouTube.

Here's an excerpt from  a news article on the Telegraph:

Even eminent television physicist Professor Brian Cox has weighed in on the mystery of Manchester Museum's moving statuette, which dates back to 1800 BC.

The 10-inch tall statue of Neb Sanu was discovered in a mummy’s tomb and has been with the Museum for eighty years, but has only recently been noticed moving.

Prof Cox, who teaches physics at the city's university, claims the movement is due to the "differential friction".

However, Manchester Museum's resident Egyptologist Campbell Price suggested something more sinister, an Egyptian curse.

"I noticed one day that it had turned around. I thought it was strange because it is in a case and I am the only one who has a key," he explained in an interview with the Manchester Evening News.

Differential friction or curse?  My guess is the differential friction is the more likely answer of the two, but I suppose it could be something else entirely that no one has thought of yet.  Either way, it's bizarre.
