Scientists Discover a Way To Get Every Last Drop of Ketchup Out of the Bottle (bbc.com)

Slashdot reader schwit1 quotes a report from BBC: Scientists in Boston have found a way to get every last drop of ketchup out of the bottle. They have developed a coating that makes bottle interiors super slippery. The coating can also be used to make it easier to squeeze out the contents of other containers, such as those holding toothpaste, cosmetics and even glue. The researchers at the Massachusetts Institute of Technology (MIT) believe that their innovation could dramatically reduce waste. In its manufacture, the container must first be coated on the inside with a rough surface. A very thin layer is then placed over this. And, finally, a liquid is added that fills in any troughs to form a very slippery surface -- like an oily floor. The ketchup hovers on top and just glides out of the bottle. According to Prof Kripa Varanasi, who developed the slippery surface, the technology is completely safe. "The cool thing about it is that because the coating is a composite of solid and liquid, it can be tailored to the product. So for food, we make the coating out of food-based materials and so you can actually eat it."

schwit1 adds: "Pretty slick."

    It has been doing the rounds since at least 2012. It was news back then. It's not news now.

    I first heard about these magic ketchup bottles 5, 6 years ago. Is this really that slow a news day?
