Five MIT students: Dave Smith, Rajeev Dhiman, Adam Paxson, Brian Solomon, and Chris Love, along with their professor, Kripa Varanasi, have made a major breakthrough. Last spring, they invented LiquiGlide, an edible, plant-based coating that can be placed on any surface, from glass to ceramics. Liquid-based products that encounter the surfaces will slip right off, whether it's ketchup in a bottle or rain on a jacket.
We wrote about LiquiGlide when it was first introduced in May, but now the product has been named one of Time's Best Inventions of 2012 and we're still impressed. It also came in second in MIT's $100,000 Entrepreneurship Competition.
