Welcome back to Why the Kettle Sings, I am Evan Castellano. Today, a small daily horror. You turn on the shower, and the curtain comes for you. Cold, clingy, aggressive. For years physicists genuinely disagreed about why, and I love that, because it means a question in your bathroom was hard enough to need a supercomputer. I will give you the three explanations, hot air rising, fast water pulling air, and a sideways tornado living inside your shower, and then I will show you the smoke experiment I did at home to test them, with my wife holding the camera and questioning my life choices. One explanation wins. At the end, a listener asks whether a heavier curtain fixes it. You are listening on Witspeak Podcasts. Towel ready.
