A bizarre video has emerged from China of a dancing manhole cover on a pavement in Chongqing.

The footage shows the heavy cover rattling around on top of the manhole as though it is being pushed from underneath by an invisible force.

Local residents have been trying to solve the mystery behind the strange occurrence since it began a couple of months ago.

According to local media, the puzzle has now been solved, after it was revealed that a local restaurant had connected their chimney for waste gas emissions to the underground sewer pipe.
