The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly. This works because, at temperatures above the Leidenfrost point, when water touches the hot plate, the bottom part of the water vaporizes immediately on contact. The resulting gas actually suspends the rest of the water droplet just above it, preventing any further direct contact between the liquid water and the hot plate and dramatically slowing down further heat transfer between them. This also results in the drop being able to skid around the pan on the layer of gas just under it.* *Wikipedia entry on "Leidenfrost effect"

Aaron Keller, Chemistry Teacher, talks about and demonstrates the Leidenfrost effect using both liquid nitrogen and water. The Leidenfrost effect occurs when a liquid comes in contact with a surface much hotter than its boiling point. A layer of evaporated (gaseous) vapor forms between the liquid and the hot surface, preventing further rapid boiling. The gas transports heat less efficiently than the liquid and if the liquid is in the form of drops, then the drops last much longer than intuition would lead you to believe.

This is most commonly seen when cooking; one sprinkles drops of water in a skillet to gauge its temperature—if the skillet's temperature is at or above the Leidenfrost point, the water skitters across the metal and takes longer to evaporate than it would in a skillet that is above boiling ''

The Leidenfrost Effect (en.wikipedia.org is when a liquid boils, producing an insulating layer of gas. This phenomenon is seen when the liquid comes into contact with a mass significantly hotter than the liquid's boiling point. This originally was an audition tape for an upcoming science/stunt show. I didn't get the role, but thought I would reedit the clip for educational use. **DO NOT TRY THIS AT HOME!!** (I tried it at my parent's home instead ;) Film was written, directed, filmed, produced, edited, and acted by Timotheus. Thanks to Mary for assisting in some of the filming when a tripod just wouldn't work, and to Chris and Brenda for loaning me their camera. Film was written, filmed, edited, and finalized in only 8 hours.

The efficient transfer of heat from a solid to liquid is critical to many everyday devices: kettles: boilers: power stations and cars. If teh solid gets hotter the heat transfer improves, but if the solid gets too hot, the liquid vapourises, and vapor film forms between the liquid and the solid, reducing heat flow dramatically. This film formation is the Leidenfost effect.

A Red Hot glowing copper coin is added to Methanol. As the copper coin is much hotter than the boiling point of Methanol, it is surrounded by a "protective" layer of Methanol vapor, keeping the Methanol from touching the copper coin. As the copper coin cools, this layer collapses, exposing itself to the Methanol and brings about a second boil.

Filmed with a high speed camera, this video shows how droplets of liquid nitrogen behave when poured on a warm surface like the floor. Since the floor (at room temperature) is much hotter than the boiling point of liquid nitrogen, the droplets boil very quickly. When this happens, a thin layer of nitrogen gas is formed underneath the droplet. This cushion of gas allows the droplet to glide over the floor nearly frictionless, much like a hovercraft would. The same effect can be seen when you throw a few drops of water in a hot frying pan. For more information on this demo and more, check out our website at: www.ap.smu.ca
