Leave it to a couple of brain childs to want to solve the ketchup bottle problem. LOL
It has a practical side, it will save lots of wasted food left in the bottom of container, no dirty spoon to wash after trying to scrap out the last bit, and how about putting that coating on shower walls, inside refrigerators, cars exteriors, building so no graffiti will stick? No more dirt to stick to anything. Now this is my kind of invention.
