How did Mohe pour water into the ice?

In the winter of recent years, photos of "splashing water into ice" will be popular on the Internet. Can water really turn into ice in an instant? The experimenter came to Polaris Square in Mohe County, prepared three kinds of water with different temperatures, and carried out a water splashing experiment with a thermos cup with a filter to witness whether the water can be "splashed into ice" in extremely cold weather.

At 8: 40 on February 10, shortly after the sun rose, the temperature in Polaris Square in Mohe County, Heilongjiang Province was only -36.4℃. First of all, the experimenter prepared a cup of cold water with a temperature of about 10℃, jumped hard and threw the water into the air at the same time. As can be seen from the photos, the water in mid-air is still in the form of water and has not turned into ice.

After that, the experimenter replaced the water in the cup with warm water close to body temperature (37℃) and threw it into the air again. At this time, some water vapor appeared in the air, but it has not reached the amazing effect of online pictures.

Finally, the experimenter replaced the cup with hot water of about 90℃ and poured the water again with all his strength. At this time, the "miracle" appeared.

Around the arc of hot water falling, a white object appeared, inlaid with Phnom Penh under the sunlight. Is this fog, steam or ice?

But this is really not ice! The experimenter confirmed that the spilled water was still water at the moment it landed. Because the ground temperature is too low, close to -40℃, the falling water freezes after a few seconds.

It can also be seen from the photos that the ice on the ground is frozen by flowing water, indicating that the water falls to the ground or water.

Zhang Jihuai, an expert in cloud physics at the Institute of Meteorological Science of China Meteorological Bureau, said that -40℃ is the critical temperature for water droplets to instantly turn into ice, and it is basically difficult to splash water into ice above -40℃.

When the temperature is lower than -40℃, although the basic conditions for water droplets to freeze are met, it is likely that the spilled water will still fall to the ground in the form of "water". Because the outer layer of countless spilled water droplets freezes quickly, but there is still water inside, it will take some time for the water droplets to freeze completely.

Bian Xiao reminded that when splashing water, try to splash it obliquely, and don't use boiled water! Don't use boiling water! Avoid "wet body" and avoid being burned!

Bian Xiao also reminded that when taking pictures, shoot against the light and choose the morning or afternoon when the sun is low; The exposure speed is suggested to be one thousandth of a second, continuous shooting. So you can take amazing photos of "dominating" your circle of friends! (Photo: Li Zhe experimenter: Hu Jianjun, Tang Yu 'ang)
