Smelly white foam bursting out of sewers submerges Chinese streets
A mystery white foam bursting out of sewage pipes submerged streets in a city in northern China.
The video, shot in Xi'an City in Shaanxi Province on Tuesday (May 22), shows a large amount of foam covering a street for more than 200 metres.
Workers tried to use water to wash the foam away, but it came out of the manhole again.
According to the local Environmental Protection Bureau, the white foam might be caused by leaking washing liquid. Cleaning work to remove the foam has since been finished.
