In cold and arid climates, such as the Himalayas, access to water is severley reduced and heavily dependent on the month of the year. A solution to this problem is to store it in the form of artificial glacier, or ice stupas. These stupas are formed by freezing atomised water jets during winter and result in a conical shape. Inspired by this, we studied the development of capillary stupas, that is stupas obtained by freezing droptlets impacting a cold substrate. We observed the development of a rich and complex shape that is the result of several mechanisms such as rivulet flowing and freezing.
