  • Tube 1 – water and air

  • Tube 2 – water but no air (it is removed during boiling and the oil prevents any extra from dissolving in the water and reaching the nail)

  • Tube 3 – water, air and salt

  • Tube 4 – air, no water (the calcium chloride removes the water from the air and the bung prevents any extra from entering.)
