sci || tech || history on Instagram: "Non-Newtonian fluids don’t follow the normal rules of flow — and that makes them incredibly useful. 🧪⚙️ This video explores how materials that change viscosity under stress are applied in modern technology. When left undisturbed, these fluids flow easily, but under sudden force they stiffen or harden instantly. Engineers use this behavior to solve real-world problems where flexibility and protection are both needed. From safety gear to advanced machinery, n
