Summary:We made a LC shell covering a water droplet floating on a fluorinated liquid and examined its shape and properties. In the equilibrium state, the shell formed unusual asymmetric shapes, depending on the LC phases. Since the LC shape should be determined by the balance between the Frank elasticity, surface tensions and line tensions, the various shapes can be ascribed to the difference of the elasticity in each phase. The dependency was not observed when the inside water was replaced by an ion solution because the ion changed the anchoring of the droplet surface from planer to homeotropic. We also found that the shell shape drastically effected the water vapor evaporation from the droplet.
