Summary

Description
English: Two identical circular jets of water collide into each other. To the naked eye they form a blurred liquid fan. Inspired by the images of flying bullets from Doc Edgerton (MIT pioneer of high- speed imaging), we visualized these phenomena using a high-speed air- gap flash that releases a 20,000 volts arch into the air in less than 300 nanoseconds and captured some mesmerizing patterns that resemble a fishbone structure. The momentum of the impacting jets flattens them into an expanding planar sheet that becomes unstable due to the capillary effect. Individual water ligaments stretch out of the rim of this liquid sheet and break into individual spherical droplets. Each droplet/ligament acts as a spherical/cylindrical lens. Using the lens effect we can see a projected image of the background (falling peaches).
