We all thought accidental breakages were bad enough, especially in the vain pursuit of selfie glory.

Yet, the art wreckers of the world have taken things to a whole new level, with deliberate damage now being the new fear for curators and art lovers everywhere.

CCTV footage released from the Shangai Museum of Glass reveals the destruction caused by two young children, seen breaking a sculpture while their adult chaperones look on with their cameras.

The boys are seen to be playing past the rope barriers surrounding the mounted artwork, pulling at the fragile glass structure while both adults whip out their phones to film their play; except for when one particularly strong tug shatters the bottom of the piece, with the adults finally gesturing their children to move away.
