Supercritical water possesses vastly different properties compared to its liquid phase, for instance it is well known that the famous tetrahedral H‐bond network is destroyed. In their Research Article on page 18578, P. Schienbein and D. Marx further unveil that supercritical water should not be considered as a H‐bonded fluid at all due to ultrafast reorientational dynamics on the timescale of intermolecular H‐bond vibrations. Instead, it behaves much like an isotropic van der Waals fluid.
