Salty Water

“Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.” Matthew 5:13.

Salt is used to season our food to taste more vibrant and full of flavor. We are to be salty Christians who are testifying that God’s love fills our hearts, so that when others come to know us, they will experience the fullness of God’s great love within and without us.

Salt in our water is not good for us to drink. Why? Your body is not made to consume the salt water. Your kidneys will only make urine that is less salty than the salt water you may have drank. So in order to get rid of the excess salt, you will have to expel more water than you drank which means you will quickly become dehydrated which is dangerous for your health.

Today many countries use salt water to get salt. Have you ever wondered how they do this? In the following experiment you will learn how you can take salt water and soon have salt.


  • cookie sheet
  • 2 sheets of black construction paper
  • 2 tablespoons (30 ml) table salt
  • 1 cup (250 ml) tap water
  • spoon


  • Cover the bottom of the cookie sheet with the black paper.
  • Add the salt to the water in a the cup and stir. Most, but usually not all, of the salt will dissolve.
  • Pour the salt water over the paper. Allow the undissolved salt onto the paper. Allow the undissolved salt to remain in the cup.
  • Place the cookie sheet in a sunny place where it will not be disturbed for several days. This can be by a window or outdoors if the weather is warm and dry.
  • Observe the paper daily until it is dry.

What do you see now that it is dry? You should see a thin layer of white crystals forms on the paper. Later, a few small, separate white, cubic crytals will form.
How did this happen? As the sun heats the salt water, the water evaporates and dry salt is left on the paper. This method of having dry salt from water is known as the solor process, and the product is called solar salt.

“In casting salt into the bitter spring, Elisha taught the same spiritual lesson imparted centuries later by the Saviour to His disciples when He declared, “Ye are the salt of the earth.” Matthew 5:13. The salt mingling with the polluted spring purified its waters and brought life and blessing where before had been blighting and death. When God compares His children to salt, He would teach them that His purpose in making them the subjects of His grace is that they may become agents in saving others. The object of God in choosing a people before all the world was not only that He might adopt them as His sons and daughters, but that through them the world might receive the grace that bringeth salvation. When the Lord chose Abraham, it was not simply to be the special friend of God, but to be a medium of the peculiar privileges the Lord desired to bestow upon the nations.” Prophets and Kings, 231:4.
