As soon as it snows, the first desire for both adults and children is to run outside, play snowballs and make a snowman. It turns out that such winter fun is by no means alien to nature itself. In North America, as well as in some European countries, scientists have recorded a curious natural phenomenon called "snow rolls". These are cylinders of snow, rolled by the wind, they are hollow on the inside, but very strong on the outside.

Snow rolls can be completely different in size: from very small, resembling a tennis ball, to large, reaching 25-30 cm in diameter and 30 cm in width. The size of the roll depends on how strong the wind was, sticky - snow, in addition, it is obvious that large "bundles" are obtained if the wind blows them off the slopes of hills or other elevations.

In order for a snow roll to form, the air temperature must be around zero, and the top layer of snow must be sticky. Then the wind literally pulls out lumps of snow and rolls them over the ice cover, the principle is akin to how children sculpt snow women. At a certain moment, the roll stops, if it is not covered with snow, it will be visible until it gradually melts.

The rolls, rolling down, leave long grooves in the snow cover, which can often also fold into bizarre patterns. By the way, such modern artists as Simon Beck and Sonya Hinrichsen took the principle of "trampling" pictures on the not freshly fallen snow as the basis of their work, so there is no doubt a lot to learn from nature.
