It was claimed that if one observed when the ink stopped swirling, meaning the viscosity of the water had dissipated its initial vorticity or curl; i.e.\nabla \times U = 0 then, if the plug was extracted ever so slowly so as not to introduce any additional vorticity, the tub would empty with a counterclockwise swirl in the northern hemisphere.
