Liquid marbles have promising applications in the field of microreactors, where the opening
and closing of their surfaces plays a central role. We have levitated liquid water marbles
using an acoustic levitator and, thereby, achieved the manipulation of the particle shell in a
controlled manner. Upon increasing the sound intensity, the stable levitated liquid marble
changes from a quasi-sphere to a flattened ellipsoid. Interestingly, a cavity on the particle
shell can be produced on the polar areas, which can be completely healed when …
