10 months agoIt’s toxic, but a useful reference point: tungsten hexafluoride is one of the densest known gases in existence. At a density of 13kg/m^3 at standard temperature and pressure, it is nearly two orders of magnitude shy of being dense enough to bring a human (~1000kg/m^3) to neutral buoyancy.
Yeah, that’s a monkey paw wish. His “ending the war in Ukraine” almost certainly means giving Putin whatever he wants.
