Salt Does NOT Melt Ice (It's not what you think) | Feynman Explains Why

You've seen it a thousand times: salt hits ice, ice disappears. Simple. Except the explanation you learned as a kid is completely backwards. Salt doesn't "melt" anything — the ice was already melting, every second, all on its own. What salt actually does is far sneakier, and it reveals one of the deepest principles in all of physics. In this video, we explore the real molecular mechanism behind salt and ice through the lens of Richard Feynman's teaching style — drawing on his explanations of thermal equilibrium, phase transitions, and colligative properties from The Feynman Lectures on Physics. 📚 SOURCES: Richard P.
