A drop of viscous-shear thinning fluid is squeezed between parallel-plane walls due to gravity. The liquid drop partially wets each surface with constant contact angle. A constant load of magnitude, F, applies a force that squeezes the drop until a critical time after which it begins to spread due to capillary pressure. The squeezed drop is examined both experimentally and theoretically for gap spacing smaller than the capillary length.
