Leidenfrost effect

The Leidenfrost effect occurs when a liquid, like water, comes into contact with a surface significantly hotter than its boiling point. Instead of immediately evaporating, a vapor layer forms beneath the liquid droplet, creating an insulating barrier. This allows the droplet to glide over the surface without quickly evaporating. A common demonstration of this effect is when water droplets dance on a hot skillet. The phenomenon highlights the interplay between temperature and phase changes, illustrating fascinating properties of heat transfer and fluid dynamics.
