  • The liquid exists, yes. But it has only been put to "practical" use for animals such as the rat in the movie. This hasn't been perfected for human use yet. http://en.wikipedia.org/wiki/Fluid_breathing#Use_in_diving http://en.wikipedia.org/wiki/Scuba_equipment#Liquid_breathing
  • This could be an urban legend but I read that this technology was used on consenting prisoners. The outcome was that it was possible for a short period of time. Subjects complained of discomfort. An unexpected result was that the subjects lungs appeared to have less contaniments?
  • Another article on liquid breathing is here: http://pregnancytoday.com/reference/articles/breathe.htm It seems this technology is being used to help keep premature babies alive as well.
  • It does not exist in that form or that color. the idea behind it is completely false too. babies do not actually breath the amniotic fluid in their sac. they "breath" through the umbillicle chord as blood rich oxygen passes back and forth between the mother and child. this is why it is so harmful if a mother smokes. However.... scientists have managed to create a super oxygenated water like fluid that has sustained a mouse or rat when immersed in it.
  • Perfluorocarbons have been investigated for decades as an oxygen-rich liquid which could fill the lungs and be breathed, instead of air or oxygen gas. There's a famous image of a mouse submerged in such a liquid, in no apparent respiratory distress. Unfortunately it doesn't actually work on large animals or humans (except for some premature newborns), but research continues. Perfluorocarbons have also been tried as blood substitutes, to avoid emergency blood transfusions as treatment for severe blood loss (trauma or surgery). Unfortunately clinical trials have shown serious complications (such as pulmonary edema or kidney damage) making them unsuitable for routine clinical use. If they worked better, then blood transfusions could become obsolete. Here again, research continues.
