  In this study, we present for the first time the observations of a freezing
liquid marble. In the experiment, liquid marbles are gently placed on the cold
side of a Thermo-Electric Cooler (TEC) and the morphological changes are
recorded and characterized thereafter. These liquid marbles are noticed to
undergo a shape transition from a spherical to a flying-saucer shaped
morphology. The freezing dynamics of liquid marbles is observed to be very
different from that of a freezing water droplet on a superhydrophobic surface.
For example, the pointy tip appearing on a frozen water drop could not be
observed for a frozen liquid marble. In the end, we highlight a possible
explanation for the observed morphology.
