This is scientific Americans 60 second science. I'm Chelsea Wald, got a minute?
Vinegary dressing:
When you shake it, little vinegar droplets scatter to the oil. But when you put it down, the droplets merge and the dressing separates. That is probably not a big inconvenient to you. But it is the industries that use lots of vinegary-like mixtures. So the study is on mixing, French researchers plan to flow water droplets one another time through a channel of flowing oil. The channel widened to the middle. So the oil would slow down in bond the water droplets together. Than the passage nieold again, so the oil would speed up and pull the droplets apart. The researchers expected that the droplets would merge when they bonded together. But that’s not what happened. In fact, it was the droplets started to pull apart for each other that they suddenly mixed. In physical revealed letters the researchers said the pulling apart may make the pressure between the droplets foul, that would make the droplets birthduban and then they could merge into one big water droplet. Would the researchers don’t say is whether this finding could lead to a true breakthrough? Stay mixed salad dressing.
