- A man in China shows how water froze the second the bottle was opened
- The impressive video shows a natural phenomenon known as ‘supercooling’
- Liquid water will crystallise instantly when it’s exposed in sub-zero temperature
This is the incredible moment water froze as soon as it was exposed to air on a harsh winter day in northern China.
Footage shows a man standing outdoor and opening a bottle of drinking water.
The extreme cold temperature means the liquid turned into solid ice instantly as he twisted the cap.
The mobile phone footage was said to be taken in Hulunbuir, Inner Mongolia, on December 12.
A man in red down jacket can be seen holding a bottle of water as he stands outside under a temperature of minus 20 degrees Celsius.
The water turned into ice as soon as he opened the cap.

The impressive video shows a natural phenomenon known as ‘supercooling’.
‘Supercooling’ means when water remains a liquid state but the temperature of the surrounding environment is below freezing point.
The water will crystallise immediately as soon as it’s in contact with a little piece of dust or other impurity in the water, or even a scratch on the bottle, according to Science Daily.
The action of opening the water bottle has stimulated the water and it turns into ice in seconds (left). Within 30 seconds, the whole bottle is completely frozen (right)
