Leidenfrost effect in slow motion
A fascinating video showing the Leidenfrost effect in slow motion.
Water droplets (coloured blue with food colouring) are squirted onto a hot plate which has been heated to 300 degrees celsius.
The bottom of the water drops in contact with with the plate boil and produce a thin layer of steam. This steam causes the remaining water droplet to hover. The steam also insulates the drop from the heat, so that the water drop does not continue to heat and so bounces across the surface and off the edge of the hot plate.
Occasionally the water drop does continue to heat, the expanding water causes the droplet to explode.
