LaoWhen cornstarch is mixed with water, the starch granules absorb water and swell, forming a suspension. This mixture has properties of both a liquid and a solid, creating a colloidal substance known as a non-Newtonian fluid. The starch granules in the liquid can move past each other like a liquid, but when pressure is applied, they can also lock together like a solid.
