It’s nice to know, in this ever-changing world, that there are some things we can depend on. The laws of thermodynamics, for instance. Solids, liquids, and gases always change phases at predictable temperatures and pressures… right? Well, brace yourselves, because there are some phenomena that test even these seemingly basic rules of nature! Consider for a moment: the Leidenfrost effect. The Leidenfrost effect is what you see when a liquid comes in contact with an object that is a lot hotter than the liquid’s boiling point. When this happens, the liquid doesn’t boil away, as you’d expect. Instead, it hovers over the superheated surface, suspended on a tiny cloud of its own gases. This rather strange effect is named after Johann Gottlob Leidenfros...
