Years ago, I believe the 3M company showed a TV ad with a mouse submerged in a liquid that it was supposedly breathing. Then a few years ago the movie "Abyss" had a human being breathing a liquid. I heard that the liquid actually exists but I have heard nothing more about it. It has a fairly long name which I can't remember plus I heard years ago that it was going to be the substitute for blood transfusions because of its oxygen content. Did something go horribly wrong somewhere and was the product banned? Can anyone shed some light on the fate of this liquid?
