Leidenfrost Dynamics: Supplemental Video 6

A supplemental video from the 2013 review by David Quéré, "Leidenfrost Dynamics," from the Annual Review of Fluid Mechanics.

Combined videos showing the fall of a centimeter-size steel sphere at 25°C (on the left), 110°C (in the middle), and 180°C (on the right). At 110°C, there is an intensive bubble release (this temperature is above the boiling point of liquid, here FC-72 like in Supplemental Video 2). At 180°C, there is a continuous vapor film (it is above the Leidenfrost temperature), which makes its final fall velocity much higher than in the other cases. The movie is slowed down by a factor 30.
