Mechanism of Oobleck - Non-Newtonian Fluid

  1. Jan 24, 2014 #1

    What is the molecular-level mechanism of shear-thickening of oobleck (cornstarch-water paste)?

    I don't think there is a molecular level mechanism - I am under impression it is an effect of the interaction of starch grains, which are composed of many polymer molecules.

    But I can be wrong.
