FYI, Pringles is not a "potato chip." It's an engineered potato product quite like sausage. Sure, there's potatoes in there, but lots of other stuff that has nothing to do with potatoes too.
If most of you saw the sludge that becomes a pringle product, I think you'd stop eating them. Second on this list is pop chips.
Food manufacturing is not a very well known industry. Let's just say it doesn't look so tasty down on the very, very, very, very clean floor.
