Winners of WSC: Non-photographic media

A frozen drop of water in a very cold environment. Video.
Author: Maxim Bilovitskiy from Estonia.

The following post list the winners of WSC 2017.

Comment from the jury:  In a category where many finalists were equally appreciated for their technical features, this video was preferred because of its simplicity. It reminds the concept of phase transition, a basic physico-chemical phenomenon taught in schools, which is here presented under a different perspective. The technical expertise is present in the very low -180 °C temperature. Such information about the temperature pushes the viewer to rethink what he saw and compare with the more standard phase transitions occurring in every day’s life.

Comment from the author: I always enjoyed chemistry, as well as many physical processes. At the end of 2016, I conducted experiments with liquid nitrogen, and I wondered how the water behaved on the surface of a cold copper plate that was in a foam box with liquid nitrogen. At first, the water just froze very quickly, but when it reached a certain height I began to notice that the frozen water began to become covered with beautiful ice crystals. This process is most likely caused by the presence of a large amount of water vapor in the air at the temperature boundary. The video was made on a 90mm macro lens with side illumination.
