The video shows the behavior of a flexible cantilever beam in the wake of a cylinder. We use vertically falling soap films to visualize the flow and record the images at 5000 fps. We observe a lock-in behavior of the cantilver's free end in the midst of the downstream von karman vortex street generated from the cylinder.
