<< My laser shop claims to have a 55,000 psi waterjet. That's 24 miles deep in a hypothetical ocean. Few materials could contain such pressure, let alone create it. Wouldn't rocks 24 mi underwater turn to mush from effects tending to change their surface area? Or would the water turn solid?
Don't know about the physical effects, but 55,000 psi sounds close to the pressure exerted by a stiletto heel (depending on who's wearing it), so not that hard to imagine. --Dan
