Liquid marbles are continuing to draw the attention of investigators[1–4]. Liquid marble, shown in Fig. 1, is the non-stick droplet encapsulated with micro- or nano-scaled solid particles[5–
7]. Since liquid marbles were introduced in the pioneering works
of Quèrè et al., they have been exposed to the intensive theoretical and experimental research[8–13]. An interest in liquid marbles
arises from both their very unusual physical properties and their
promising applications. Liquid marbles present an alternate
approach to superhydrophobicity, i.e. creating a non-stick situation
for a liquid/solid pair. Usually superhydrophobicity is achieved by
a surface modification of a solid substrate. In the case of liquid
marbles, the approach is opposite: the surface of a liquid is coated
by particles, which may be more or less hydrophobic[13]. Marbles
coated by graphite and carbon black, which are not strongly
hydrophobic, were also reported[14,15].
