A Crack in the Mystery of Oobleck: Friction Thickens Fluids

The video explores shear thickening fluids, focusing on oobleck, a material that behaves like a liquid when moved slowly but becomes solid-like under rapid force. Two theories explain this behavior: particle jamming and friction. An analogy with wet sand illustrates the concept. Research shows friction is the primary cause of shear thickening, with applications in cement, chemical mixing, and body armor.
