Newly formed ice crystals fall earthward, and the energy released in their transition from liquid to solid evaporates nearby water drops, leaving a hole in the cloud.

During drying, the Sunset Yellow concentration varied within the drop, and microscope images revealed the formation of different fluid phases such as the isotropic liquid (random), liquid crystal nematic (aligned) and liquid crystal columnar (cylindrically packed) phases that segregate to different regions of the drop.

Although there have been other investigations in which multiple phases arise in drying and evaporating drops, especially near the drop edge, this is the first time researchers have investigated multiple liquid crystal phases and understood how viscoelastic effects and other properties of liquid crystals affect the final drying deposition pattern.

As the concentration of the drops increases further, however, the liquid crystal evolves from the nematic phase to the «columnar» phase, in which the rods pack together like bundles of straws.
