Every plumbing fixture, from a toilet to a shower, needs to be connected to ventilation piping. The pressure of outside air drawn in from ventilation pipes helps push waste or used water down through drain pipes.
A potato chip (American English) or crisp (British English) is a thin slice of potato that has been deep fried, baked, kettle cooked, or popped until crunchy.Potato chips are commonly served as a snack, side dish, or appetizer.The basic chips are cooked and salted; additional varieties are manufactured using various flavorings and ingredients including herbs, spices, cheeses, and artificial additives.ome chip vendors offer chips that have been baked instead of fried. Although these chips offer much lower fat content, many of the commercially produced baked potato chips contained more sodium than their fried counterpart from the same manufacturer.
Making potato chips was a lot of work, since the potatoes had to be peeled and sliced by hand. That all changed in the 1920s, though, with the invention of the mechanical potato peeler. With the help of technology, potato chips grew from a local favorite into a nationwide sensation. Today, potato chips are one of the most popular snack foods in the world.
