On February 19, within the framework of the library laboratory «Funny Science», a master class «Magic Snow» was held. The guys made snow that does not melt even in the heat. Artificial snow with amazing properties surprised children and adults. The experiment was simple and safe, aimed at developing the children’s skills: to observe, compare, generalize, and draw conclusions. The students were asked to repeat the same experience at home with their parents and friends. Magic snow can be used many times: in a few days, after the moisture has evaporated from it, the snow will turn into powder again. At the end of the master class, a thematic review of books and journals on entertaining chemistry was conducted.
