  Liquid marbles are non-stick droplets covered with micro-scaled particles.
Liquid marbles demonstrate quasi-elastic properties when pressed. The
interpretation of the phenomenon of elasticity of liquid marbles is proposed.
The model considering the growth in the marble surface in the course of
deformation under the conservation of marbles volume explains
semi-quantitatively the elastic properties of marbles in satisfactory agreement
with the reported experimental data. The estimation of the effective Young
modulus of marbles and its dependence on the marble volume are reported.
