SELF PROPELLED - LIQUID DROPLETS

Self Propelled Liquid Droplets : When a liquid drop is placed on a surface held at a temperature much higher than the liquid’s boiling point (such as a drop of water in a very hot pan) it hovers on its own vapor cushion, without wetting the surface. This phenomenon is called film-boiling and occurs beyond a surface temperature called the Leidenfrost point (about 200 - 300 ºC for water on flat surfaces, depending on surface quality).Please take your time to check the other movies.Contact: Heiner Linke,Associate Professor
