These are drink "cubes" frozen in a specially shaped molded silicone, metal, and plastic tray that makes ice that includes fissures, prominences, and calving fractures.
The different rates of freezing caused by the carefully arranged molds and different materials result in a Berg Cube that will roll, split, calve, and present different faces to the drinker throughout their beverage.
