Coandă Effect

The Coandă Effect is a phenomenon where a fluid (like air or water) tends to stick to a nearby surface and follow its shape. When a fluid flows close to a curved surface, it naturally tends to stay attached because of differences in pressure created by the flow's behavior. This effect explains how airplanes' wings generate lift, how a curved spray of water stays attached to a hose nozzle, and why a spoonful of liquid might follow the shape of a spoon when poured. Essentially, the fluid "clings" to surfaces, altering its direction due to surface proximity and flow dynamics.
