At the right temperature, if you toss a drop of water into the pan, it won’t evaporate instantly but roll around like an air hockey puck instead. That’s because the principle, called the Leidenfrost effect, is the same in your kitchen as at the arcade. A thin layer of gas between the puck and the surface below allows the disc to become almost frictionless, while in the case of your droplet, a thin layer of water instantly vaporizes when it touches the hot metal, providing a gaseous coating that allows the rest of the droplet to coast on steam.— Hugh Neill
