Understanding the dynamics of liquid films that make up bubbles is ofpractical and fundamental importance. Practically, this understanding iscrucial for tuning bubble stability, while fundamentally, thin films are anexcellent platform to study 2D flows. Here we study the spatiotemporal filmthickness dynamics of bubbles subjected to evaporation driven Marangoni flows.Initially, we demonstrate how bubble stability can be dramatically tuned withthe help of evaporation driven flows. Subsequently, we reveal that the spatialsymmetry of thickness profiles evolves non-monotonically with the volatilespecies concentration, with profiles being axisymmetric at the two extremes inconcentration. At $50\%$ concentration, spatial symmetry breaks down andthickness fluctuations are chaotic everywhere in space, with the fluctuationstatistics becoming spatially invariant and ergodic. For these cases, the powerspectrum of thickness fluctuations follow the Kolmogorov $-5/3$ scaling - afirst such demonstration for forcing by evaporation. These results along withthe reported setup provide an excellent framework to further investigate 2Dchaotic flows.
