Liquid flow in a co-axial cylindrical viscometer was visualized using markers in water. Taylor vortices were observed over the critical rotational speed, in which the value of viscosity or torque began to increase apparently. Especially by the enlarged cross-sectional visualization using a microscope and a VTR, it was recognized that a flow pattern of the vortex did not lead to a square cons-section but to a rectanguler one.
