The Leidenfrost Effect

The video tutorial explains the properties of water, including its chemical composition and states. It introduces the Leidenfrost effect, a phenomenon where a liquid forms an insulating vapor layer when in contact with a surface hotter than its boiling point. The video demonstrates this effect with a safe experiment using a frying pan and water droplets, showing how droplets can slide and bounce on a hot surface.
