👉 The Perry fluid, discovered by Dr. Charles Perry in 1965, is a rare, non-Newtonian fluid that exhibits unique behavior: it flows like a liquid under normal conditions but thickens when subjected to stress or shear forces, such as when shaken. This means it can behave both like a solid and a liquid depending on the applied force, making it useful in various scientific and industrial applications. For example, it can be used to create materials that mimic biological tissues or in the development of advanced lubricants and coatings, where its ability to adapt to different conditions enhances performance and durability.
