Vortex shedding in the wake of a stationary cylinder in a vertically flowing soap film at Reynolds number Re ~ 3600. The characteristic staggered arrangement of vortices is the celebrated von Kármán vortex street.
In this video, a cylinder penetrates a downwards flowing soap film. Thin-film interference shows the vortices formed by the comlicated interaction of flow and structure.
