The ever increasing interest in the field of liquid marbles urges the need to introduce new approaches and techniques for characterization of the unique properties of these interesting phenomena. An important characteristic of the liquid marble which has so far been partially investigated is ‘the effective surface tension’. In this paper, we have taken advantage of two main approaches; the capillary rise technique, as well as Wilhelmy plate method, to further study the liquid surface tension. Moreover, a very powerful yet straightforward equation is provided which can be utilized for the calculations followed by the capillary rise measurements. The introduced theory and techniques in this work can be employed in the design of liquid marble- based systems, such as micro reactors, and micro pumps.
