Multiple closely spaced bluff bodies are moved through a thin soap film illuminated by monochromatic light. A truly two-dimensional wake flow is produced and indicated by the deformed diffraction patterns of soap film. The picture shows the wake of three cylinders placed in line and an equal distance apart with a ratio between the surface of the cylinders and cylinder diameter of 5.7. The towing speed of the bodies was about 35 cm/sec. with the flow from left to right.
