A river turned totally white after a milk tanker on a nearby road overturned and its contents spilled into the water.
Gallons and gallons of milk flooded the Carmarthenshire river in Wales following the accident.
A local man captured the moment the milk turned the water white on Wednesday afternoon and posted a clip on social media.
Wales Online report that the A482 in Llanwrda is still closed as emergency services deal with the incident.
Footage of the river shows it has turned pure white after contents of the tanker spilled into the local water system.
May Lewis posted a video on Twitter which shows milky white water flowing over a small waterfall.
The milk can be seen flowing down the river in a sea of white as onlookers are shocked by what is going on.
National Resources Wales said they were aware of the incident which caused "significant discolouration".
A spokesman said: "Officers have been on site on Wednesday to assess the impact and will continue on Thursday morning."
On Thursday, traffic monitoring system Inrix said that the road remained closed between the A40 Llandeilo turn off and Bridgend Inn.
It warns motorists: "Road has been closed since Wednesday afternoon and will remain closed into Thursday morning as the tanker still needs to be emptied and recovered."
There is no indication yet when the road will re-open.
After the video was uploaded to twitter, some saw the funny side.
"Get the coco pops out," one user responded to the woman's clip.
But another on the platform warned: "I hope @EvnAgency are responding rapidly to this as deoxygenation of the water can lead to significant fish kills."
