Opened in 1895, this granddaddy of wallpaper factories uses century-old machinery to produce 100 million feet of cutting-edge wall coverings every year. A health-minded visionary first invented the Vitamix blender in 1937--the smoothie and margarita-making marvel that's built to last and now more powerful than ever. A high school supply powerhouse, this Pennsylvania factory churns out 36 million wire-bound notebooks every year using just one giant machine. If you're looking to order individually wrapped custom-colored drinking straws by the truckload, then swing by the Canadian factory that produces 5 million of them every week.
