Jet formation and instability of a breaking axisymmetric standing wave —

Video of Jet formation on an axisymmetric standing wave created in the FloWave circular wave tank at the University of Edinburgh. A jet emanates from the crest of the wave, which is produced by the collapse of the preceding trough, the jet then undergoes free fall where Plateau-Rayleigh instability is observed. The video has been slowed down from a frame rate of 125 fps to 30 fps.
