| Leidenfrost discovered in 1756 "the spheroidal state of water", where this common liquid behaves very differently owing to the presence of a hot material below it. We discuss several properties of the Leidenfrost state, among which the possibility of levitating solids, the ability of drops or solid platelets to self-propel on asymmetric patterns, and the "cold" Leidenfrost regime recently described by Vakarelski et al. |
