Pseudoplastic fluids are shear thinning fluids, the opposite. The viscosity of these fluids decreases as the shear rate increases. These types of fluids are much more common than dilatant fluids and naturally occurring examples include quicksand, blood, and milk. Webin stiffness is reminiscent of electrorhelogical fluids rather than the shear-thickening typically observed in polymer solutions. More surprisingly, this flow-induced gelation is reversible; if the sample is left at rest for some time, ranging from minutes to days, the gel relaxes back into a slightly viscous liquid. speeding ticket on insurance
