Mixing the Unmixable

markthebrewer writes "From an article in the New Scientist: Conventional wisdom every 15 year-old knows says that you can't mix oil and water without some kind of surfactant. However a team lead by Richard Pashley from the Australian National University in Canberra have done it simply by first removing all dissolved gases from the water. Apart from the obvious potential improvements in salad dressings, it could have an impact on the manufacture of everything from drugs to paint - anywhere an emulsion is required. Apparently, it will also give some insight into the mysterious 'long-range hydrophobic effect' (or why oil droplets coalesce over surprisingly long distances)." Keep in mind the usual scientific caveat: this experiment doesn't seem to have been replicated by other experimenters yet.

      I'm married to a teacher. I see papers like that go across her desk. She relishes giving them Zeros. -=I=- relish seeing them get Zeros. It's gut wrenching that we're creating a generation that prides itself on its stupidity.

    to adjust my phrasing:

    It's like mixing oil and water, assuming that all of the dissolved gases haven't been removed from the water.

    Yeah, that rolls off the tongue.

      As pointed out in the article, your relationships would work if you removed all gas from your system before trying to mix sexes.

    Ahhh, Once you remove all of the Hydrogen and Oxygen I can see where there would no longer be a problem!!!

    They discovered it 20 years ago but immediately covered up the knowledge because it could be used to make cars that get 200 miles to the gallon and don't produce greenhouse gasses.
