Movie S3.

Movie of one turbulent pinch-off with a persistent asymmetry in the neck shape until a kink structure forms. 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, together with the averaged diameter. 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.
