The Leidenfrost effect is one where water droplets on a hot plate float and move around spontaneously. It is an interesting fluids phenomenon, where the droplet hovers on a thin layer of vapor due to the hot surface. There are numerous experiments that can be done with this type of phenomenon, and it is a wonderful example of something that can be done in a school or home lab setting! Think of ways to vary the experiments you find in articles, to make them unique and your own - this is a way to develop your own original studies and investigations into everyday phenomena.
Check out this article that presents a 'triple Leidenfrost' example.
