Why Honey Flows Slower Than Water: Viscosity Explained

Why is honey thick and sticky while water flows freely? We all have a gut feeling about "thickness," but what is viscosity scientifically? In this video, we break down the physics of fluid flow to understand the internal resistance that governs liquids and gases. We visualize fluids as layers sliding past one another—like a deck of cards—to explain concepts like shear stress and velocity gradients. You will learn Newton's Law of Viscosity and see why some fluids (Newtonian) behave predictably while others (Non-Newtonian) break the rules entirely. In this video, we cover: The definition of viscosity: Internal resistance to flow. The "Deck of Cards" analogy for shear stress. Newton's Law of Viscosity explained simply. The famous Pitch Drop Experiment (the world's longest lab experiment!). Why heating a liquid lowers viscosity, but heating a gas increases it. Non-Newtonian Fluids: Shear thinning (paint) vs. Shear thickening. Key Concepts: τ = μ (du/dy) (Newton's Law of Viscosity) Shear Stress vs. Strain Rate Dynamic Viscosity (μ) 🔍 Related Questions Answered: What is the difference between Newtonian and Non-Newtonian fluids?
