Floating water droplets: the Leidenfrost Effect

The Leidenfrost Effect is the process of creating a layer of water vapour beneath a water droplet when you release it on a hot metal table. That metal table should have at least 200 degrees Celsius and you will then see the water droplets float above water vapours.

The Leidenfrost Effect shows up when the temperature of the heated table is way above the boiling point of water. If you put the teal sheets on a slope and then create ridges on it, then you will notice that the water droplets start racing around like crazy mice.
