As a result, small droplets disperse finely in the drink, creating a milky appearance. Researchers at TU Darmstadt have now used this so-called ouzo effect to create oil droplets for a laboratory experiment. This led to a new discovery: such a droplet can resist a fluid flow and remain in place or even move upstream.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Whether it\u2019s Greek ouzo, French pastis or Turkish raki, when these spirits are diluted with water, the mixture becomes cloudy.
