Shampoo, a shear thinning fluid, is vibrated at several frequencies. Above a critical oscillation amplitude, rolls form. The fluid flow is similar to two adjacent Rayleigh-Bernard convection cells with the left one rotating CW and the right one CCW. This video documents the behavior and formation of these rolls.
Note: Apparently youtube doesn’t let you upload copyrighted music…ignore the bit at the end.
