This Water Looks Frozen 😳

[00:00:00]Have you ever noticed how sometimes water flows in a straight smooth stream and other times it splashes and spreads everywhere? The secret behind this is something called laminar flow. When a liquid moves calmly in one direction, its layers slide past each other without mixing or colliding. That's why the flow looks so smooth, almost like it's standing still. But as soon as the speed increases or something blocks its path, the flow becomes unstable and starts moving in all directions. This is known as turbulent flow. Laminar flow is used in scientific labs, aircraft design, pipelines, and even hospitals to keep systems running smoothly and safely.
