Most people would never think of making their own salt. However, this can be a fun do-it-yourself project for both kids and adults! So grab a few ingredients and feel free to experiment away. Once you get the hang of it, you'll see that the salt-making process is quite ingenious and fun to master.
Boil a pot of water.
Add salt to the boiling water. Continue adding teaspoons of salt until the salt no longer dissolves in the water, but begins crystalizing in the bottom of the pot. This may take 2 or 3 tsp. or more, so be sure to watch carefully for crystallization.
Soak a piece of cardboard in the crystalized solution. After the cardboard is thoroughly saturated, place it in a location where it can dry out, such as outside, in the path of a sunlit window or in a warm room.
Watch for the salt crystals to form.
Break down the crystals to your preferred size once they are complete. Use as table salt.
This method can also be applied to salt substitutes and other types of salt, such as sea salt, iodized salt and uniodized salt. Both tap water and distilled, bottled water can be used to make table salt. This project may take a few experiments to master. Don't get discouraged, just get a feel for the process, the proper amount of ingredients and the length of time needed for boiling, drying and crystalization.
