Siberians spray boiling water in the cold. See what comes of it.

In social networks, a new flash mob is gaining popularity - # dubaccelling. Residents of Siberia go out and spray boiling water. In frost (in some regions the temperature dropped to 35 degrees below zero), the water instantly freezes and turns into snow figures.

The ability of hot water to freeze faster than cold water is called the Mpemba effect. In the 60s of the last century, an African schoolboy Erasto Mpemba conducted home experiments with water and then, together with a professor of physics, wrote an article about this phenomenon.

Scientists are still trying to explain the Mpemba paradox. Perhaps the problem is evaporation: hot water evaporates faster than cold water, its volume also decreases rapidly, which accelerates freezing.
