Schlieren photography allows us to image the dynamic behavior of many fluid flows that might not be visible to the naked eye. It uses the density gradients in the medium to refract light and allow us to see their behavior. In this video a jet of supersonic compressed air is imaged both alone and with a perpendicular jet of impinging high pressure water. The unseen behavior of the compressed air is captured in vivid color and puts on a spectacular show.
