Non-Newtonian fluids defy the laws of everyday fluids. They exhibit bizarre behaviors like ooblek’s stiffening when pressed and slime’s elasticity. Silly Putty amazes with its ability to bounce, flow, and mold. Dilatant gases thicken under pressure, finding use in tires and armor. Shear-thickening fluids, like ketchup or cornstarch suspensions, become viscous under stress. These extraordinary fluids have revolutionized industries, from lubricants to food products and biomedical applications.
