How to make a video of splashing water into ice?

The outdoor temperature should be at least MINUS 20 degrees. The lower the temperature, the better the effect will be. The so-called splashing water into ice means that the boiling water poured into the cup is poured out in the low temperature weather of MINUS 20 degrees and instantly condenses into ice in the air. Generally, the water temperature needs to exceed 90 degrees.

Hot water is used because it will evaporate after being spilled, and water vapor will atomize and freeze to form the effect of water splashing into ice. The thermos cup is used to avoid hot hands and frozen hands. Put the thermos cup on your chest. At the beginning of shooting, hold the cup with both hands, with the mouth of the cup facing outwards, and splash water at a certain arc. Be careful not to spill on yourself.

You can hold the thermos cup in one hand and splash water with your arm in an arc, so it is not easy to spill it on yourself.

Extended data:

Explanation 1: Hot water evaporates quickly, making it easier to form fine water droplets. When it is cold, the evaporated hot water is more likely to turn into water mist, so the effect of hot water "splashing water into ice" is more obvious.

Explanation 2: If we really want to splash water into ice, or more accurately, Zhang Jihuai, an expert in cloud physics at China Institute of Meteorology, gives a more convincing explanation.

It is said that when the ambient temperature is lower than -40℃, it is the critical temperature for supercooled water droplets to instantly become ice. When it is above -30℃, it is difficult to freeze instantly. Among them, the diameter of water droplets should be between several microns and 200 microns, which is almost equivalent to the size of the rain we usually see in Mao Mao. ?
