Caption : movie 1. confocal fluorescence microscopy video showing vacuole formation induced by the addition of teg (doped with green fluorescent teg-fitc) to a pdda : atp coacervate droplet suspensions. corresponding bright field (left) and fluorescence microscopy images are shown for two droplets undergoing reconfiguration to produce multiple internalized water droplets that coalesce into a single vacuole within the teg-containing coacervate matrix. the images are recorded 219 s after addition of teg for a duration of 126 s (see figure s2 for extended time domain). the vacuole formed within the droplet shown on the left disappears from view after 80 s due to ejection fom the droplet into the supernatant. movie is shown at ~10x speed at 8 frames per second. scale bar, 10 μm.
