The Leidenfrost effect

Tuesday, February 12, 2013


When water comes in contact with something much hotter a thin barrier forms that prevents the water from immediately boiling. This is called the Leidenfrost effect and is most common;ly seen when a drop of water skitters across a frying pan when you test it to see if it is hot enough to cook. The above video of a hot nickel ball dropped into a glass of water is a dramatic example of the Leidenfrost effect.in action.
