Dyed water and air injected into honey produces the Taylor-Saffman instability in a Hele-Shaw cell. The pressure of rapidly injecting water lifted the top sheet, inducing the instability around the outer edge of the honey as air entered. Pressure gradients caused by squeezing and pulling the plates of a Hele-Shaw cell cause the Saffman-Taylor fingering instability in honey, air and dyed water.
