  The intriguing dynamics of a compound liquid-system comprising of water and
(uncured) poly-dimethylsiloxane is explored in the present work. The
viscoelastic nature of the film, coupled with the dynamics of evaporation,
triggered a self-propulsion in the droplet, which gradually segued into the
crumpling of the film, and finally culminated in the encapsulation of the water
droplet by the polymer. The physics of the hitherto unreported phenomena has
been explained via the development of an analytical model, by taking into
account all the germane forces. It is conjectured that this symbiotic and
self-sustained dynamics, aided with the non-requirement of any complex
fabrication procedures, would pave the path for the development of precision
drug-delivery, unmediated flow-focusing, self-mixed microreactors, the study of
micro-swimmers, surface encapsulation, and photonics, to name a few.
