Leaking gas causes manhole covers to 'dance' on Chinese road
Several manhole covers were filmed "dancing" on a highway due to gas leaking in southern China.
The unusual clip, captured in Guilin City in southern China's Guangxi Zhuang Autonomous Region on May 13, shows several manhole covers on the same section of a road moving up and down.
According to reports, the natural gas leaking out of the pipes caused the moving of the manhole covers. More than 20 maintenance staff were working on site already to address the issue.
