Microscopy images of a doublet changing its strain, and thus shape, in response to a dilution-induced increase in the local interfacial tension. As surfactant diffuses back in to re-equilibrate the local concentration, the strain increases but the droplet does not return to its original strain, probably because of structural rearrangements that cause hysteresis in the droplet’s rheological response.
