Just a note, I heard one of the developers do a talk on this at one of the local dive things. Specifically, it was called "Dive Philadelphia" and was organized by one of the list-members here. Her name is Jolie, her address is jolieb@gr*.ci*.up*.ed*. Anyway, this guy (the speaker) worked on the stuff, consulted on the movie, and told us all about it. It's mostly for use with premature babies, as lung tissue is many times not mature enough to perform the gas exchange necessary to sustain life. It was also used for treatment of disease. Apparently the stuff has a very high vapor pressure, and is so completely inert that one can apparently drink it without bad effect. And it's ability to solvate and carry gasses is much higher than water. He compared it to "liquid teflon" - Incidentally, the rat thing from the Abyss was apparently real. The researcher was not allowed to do it to the rat, as SPCA was not particularly impressed with the protocol, but the film guys did it to a rat in a an hotel room, no less. Like, seriously, the rat thing was not a special effect or anything. More interesting tid-bits - apparently folks have tried the liquid breathing thing back quite a ways - even with saline solutions. The bottom line, the entire thing is real viable, and folks apparently can live for extended periods of time on the stuff. it does make a quick trip to McDonalds a little sticky, though. >On Mon, 5 Dec 1994, ANTHONY APPLEYARD wrote: > >> (5) When he got back into air afterwards, he took his helmet off while it >> was flooded, and the liquid in his helmet, and the liquid which he expelled >> from his lungs, went on the floor.
