Abstract: We report the evolution of a quasi-two-dimensional cellular structure. This soap-froth-like structure is formed by 2.24μm colloidal particles trapped at the air/water interface. The froth evolves mainly through one of the modes of the T2 mechanism, the inverse mitosis process, and in minor proportion through the T1 or side switching mechanism. In addition, particle rearrangements can also be observed during the evolution. Eventually, the colloidal soap-froth evolves towards the formation of colloidal clusters, which detach from the edges of the colloidal froth. The cell side distribution is similar to distributions from other froth-forming systems and follows the Aboav–Weaire law. Other statistical comparisons are also made with other froth-forming systems and, in general, we found similar behaviour.
