This is how I tamed the wildest, most aggressive shower curtain that ever billowed the earth. Im so glad that its unlikely in denmark to have to take showers not baths in a bathtub. Your explanation is either the Bernoulli effect theory or the Horizontal vortex theory, it would seem, as they both involve pressure differentials. Keeps the curtain from touching you. Don't listen to these lies, everyone knows that when you are hot your gravity increases there for pulling the curtains towards you. Get shower curtains with magnets if you have a metal bath tub .
