Nut & Bolt and Screw Salt and Pepper Shakers

Ask your friends at your next dinner party if they can figure out these nut & bolt and screw salt and pepper shakers:

These Salt and Pepper shakers are definitely something different. Pick them up, turn them whatever way and shake them, and..... nothing.... Bend then shake them however, and the Salt or Pepper will be sprinkled from the gaps that will have appeared between the coils. Once you are finished the shaker will return to its original form.
