شرح مختصر عن walkdown و punch list في مجال construction

Justin Sebastian on Instagram: "Non-Newtonian fluid is the ultimate rule breaker. Punch it and it turns solid. Hold it gently and it flows like a liquid. This mind-bending behavior happens because its viscosity changes under pressure, making it one of the coolest real-world examples of physics you can touch. From cornstarch and water to advanced materials used in body armor and shock absorbers, non-Newtonian fluids prove that science is stranger than fiction. #NonNewtonianFluid #Physics #Science
