The discussion centers on the molecular-level mechanism of shear-thickening in Oobleck, a cornstarch-water paste. Participants express skepticism about the existence of a singular molecular mechanism, suggesting that the behavior is primarily due to the interactions between starch grains, which consist of numerous polymer molecules. The consensus indicates that the thickening effect arises from the physical interactions rather than a defined molecular process.
