Fig. 10: Multiple crossings in five and six-core emulsions.

a–e Time evolution of the dislpacement Δzcm of the cores in a five-core emulsion. Regular periodic motion survives for short periods of time and is temporarily broken by crossings of the cores towards either the top or the bottom of the emulsion. f–k Time evolution of Δzcm in a six-core emulsion. Although some cores travel along approximately similar trajectories (such as 1, red/plusses, and 2, green/crosses), there is no evidence of a persistent coupled periodic motion involving two (or more) drops. The black dotted line is a guide for the eye indicating the separation between the two regions of the emulsion.
