Answer:
If you sprinkle water on a mildly heated pan, it will slowly boil and eventually evaporate. But something curious happens if you wait for the pan to really heat up. Water on a hot enough pan will congregate into small droplets, hover above the surface, and skittle around as if on a frictionless plane.

Answer:
Water will gradually boil and eventually evaporate if you sprinkle it on a pan that is just moderately hot. But something strange happens if you wait for the pan to get incredibly hot. If a pan is heated enough, water will condense into tiny droplets that will hover over the surface and move without resistance.
Explanation:
- Due to "The Leidenfrost Effect," water droplets on a heated pan appear to dance about the surface. This phenomenon causes a vapor cushion to form between the liquid and the surface, keeping the droplet uncannily in the air.
- The Leidenfrost effect is a physical phenomenon in which a liquid forms an insulating vapor layer adjacent to a surface that is much hotter than the liquid's boiling point, preventing the liquid from boiling rapidly. The repellent force prevents the droplet from touching the surface; instead, it floats above it. The phenomenon bears Johann Gottlob Leidenfrost after the German physician who first reported it in A Tract About Some Qualities of Common Water.
