FAQ – Oobleck

A non-Newtonian fluid is a fluid whose viscosity (resistance to flow) changes under applied stress, unlike a Newtonian fluid like water, where viscosity remains constant. This means a non-Newtonian fluid’s thickness can change when force is applied, making it behave like a solid under certain conditions and a liquid under others.
