SOAP Doesn't Actually Kill Bacteria — Feynman's Proof

You've been lied to about soap your entire life. Not deliberately — but the truth about how it works is far more interesting than the myth. In this video, we explore the real physics behind handwashing through a Feynman-style lecture drawn from fundamental principles of surface tension, molecular behavior, and amphiphilic chemistry. What seems like a simple hygiene habit turns out to be an elegant lesson in intermolecular forces — and a physics trick that's saved more lives than most modern medicine. 📚 SOURCES: Feynman, Leighton, & Sands — "The Feynman Lectures on Physics," Volume I, Chapters 1–2 (Atoms in Motion, Basic Physics), 1963 Burton, DeJong, et al. — "The Effect of Handwashing with Water or Soap on Bacterial Contamination of Hands," International Journal of Environmental Research and Public Health, 2011 Centers for Disease Control and Prevention — "Handwashing Facts: The Science Behind Recommendations," 2024 Ijaz, Nims, et al. — "Soap, Water, and SARS-CoV-2: An Ancient Handwashing Strategy," Journal of Hospital Infection, 2021 Kawahara, et al. — "Inactivation of Human and Avian Influenza Viruses by Potassium Oleate of Natural Soap Component," PLoS ONE, 2018 🎬 TIMESTAMPS: 00:00 — "Soap kills bacteria."
