Leidenfrost Effect
A water droplet lasts longer on a hotter surface
Overview
A physical phenomenon where a liquid droplet lasts longer on a surface significantly hotter than its boiling point.
Drop water on a moderately hot surface and it evaporates quickly. On a much hotter surface, it lasts longer! The droplet floats on its own vapor layer, insulating it from the heat and slowing evaporation.
