Q
Why does the shower curtain blow inward?
A
Expert Answer
The Bernoulli principle explains this: fast-moving air (from the falling water spray) creates lower pressure inside the shower than the still air outside. The pressure differential pushes the curtain inward. Curved rods, weighted curtains, or using a liner reduce this effect.
