In an article published on March 23, 2015 on the business and technology news website Business Insider, journalist Kelly Dickerson reported about an innovative coating that makes the surface of plastic and glass containers wet and slippery to allow ketchup or other products to slide right out. The coating, called “LiquiGlide”, was developed in the research group of Kripa Varanasi at MIT, U.S., who started a company of the same name together with his students. LiquiGlide creates an extra layer between the container and the liquid. Since it binds much more strongly to textured surfaces than to liquids, the liquid can flow freely over it without creating friction and viscosity. LiquiGlide’s technology is non-toxic and does not involve nanotechnology, according to the company’s website.
