Leidenfrost effect

I've always wanted a chance to demonstrate the leidenfrost effect; never knew how/where to get a supply of liquid N2 though.

The temperature at which the Leidenfrost effect begins to occur is not easy to predict.

At extremes, film boiling commonly known as the Leidenfrost effect is observed.

Superhydrophobic surface are able to stabilize the Leidenfrost effect by making the vapour layer stable.

Later, as the temperature exceeds the Leidenfrost point, the Leidenfrost effect comes into play.

This effect, known as the Leidenfrost effect, applies to any liquid in contact with an object significantly hotter than its boiling point.

'Film boiling' on very hot surfaces and the Leidenfrost effect are both believed to be stabilized by spontaneous nucleation phenomena.

Leidenfrost effect - lower temperature boilers can sometimes vaporize water faster than higher temperature boilers.

"Leidenfrost effect".

As the magma, which is significantly hotter than the boiling point of water, comes into contact with water an insulating vapor film forms (Leidenfrost effect).

"Scientists make water run uphill" by BBC News about using the Leidenfrost effect for cooling of computer chips.

Additionally, Jearl Walker has postulated that walking over hot coals with wet feet may insulate the feet due to the Leidenfrost effect.

In a phenomenon called the Leidenfrost effect, or film boiling, a layer of vapor forms beneath the droplet, keeping it elevated above the hot surface like the cushion of a hovercraft.

Full "contact" between naked skin and large collected-droplets or pools of liquid nitrogen may be prevented for a second or two, by a layer of insulating gas from the Leidenfrost effect.

Johann Gottlob Leidenfrost (November 27, 1715 - December 2, 1794) was a German doctor and theologian who first described the scientific phenomenon eponymously named the Leidenfrost effect.

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.

In the 2009 season finale of MythBusters, "Mini Myth Mayhem", the team demonstrated that a person can wet their hand and briefly dip it into molten lead without injury, using the Leidenfrost effect as the scientific basis.
