I wonder if companies will embrace this as a boon to consumers or if they can actually quantify how much money they would lose because people can get all the product out. Also the article has no information on how much the coating costs, or what kind of changes to the manufacturing process you'd have to make (like having to store the bottles somewhere post-spray to 'dry' or something). I also wonder if, in the case of the open mouth ketchup bottle, it actually makes the experience worse for a full bottle by pouring out too fast?

In any case, it's cool and I'm actually excited for the other applications of it. Seems like an endless stream of cool stuff comes out of MIT.
