Pouring liquids looks effortless, but a clean, drip-free pour is controlled by physics like surface tension, adhesion, and flow. The right tilt angle and keeping the container's lip close to the cup reduce air gaps and splashing, allowing the liquid to cling briefly to the edge before breaking cleanly into the vessel instead of running down the side. The liquid's viscosity also matters—thicker fluids need slower, controlled pours, while thinner ones require a smooth, continuous motion—showing ho
