Movie S1.

Movie corresponding to figure 2 in the main paper. Top left: Close-up views from the two high speed cameras. Top right: Neck diameters d_x and d_y in the two views during the pinch-off exhibit oscillations, while the averaged diameter follows the classic self-similar scaling. Bottom left: Velocity of the four measured thinning points. Bottom right: Difference Δr = (d_x − d_y)/2 as a function of mean neck diameter.
