Non-Newtonian Fluids

Non-Newtonian fluids are substances whose viscosity, or resistance to flow, changes under stress or over time. Unlike traditional fluids, like water (Newtonian fluids), which maintain a consistent flow regardless of the forces applied, non-Newtonian fluids can behave differently based on the conditions. For example, a cornstarch and water mix thickens when stirred quickly (shear-thickening), while certain gels become thinner when shaken (shear-thinning). This unique behavior is significant in various fields, including engineering and soft matter physics, as it influences how these materials are processed and used in applications ranging from food to cosmetics and industrial products.
