Why Your Shower Curtain Is so Annoyingly Clingy

The video explores the common issue of shower curtains clinging to people during showers. Initially, it was thought that hot air rising caused this, but the effect occurs even in cold showers. Bernoulli's principle, which relates fluid speed and pressure, was considered as a cause, suggesting that fast-moving water reduces air pressure, creating a vacuum that pulls the curtain inward. However, this doesn't account for water droplets. A mechanical engineer proposed a vortex theory, where the shower spray creates a low-pressure area, similar to a hurricane's eye, drawing the curtain inward. The video concludes that these phenomena are due to physics, not supernatural forces.
