How to Make Your Own Salt Crystals
- 1). Fill a large glass jar half full with water.
- 2). Stir table salt into the water 1 tablespoon at a time until the salt no longer dissolves into the water and begins gathering at the bottom of the jar.
- 3). Tie piece of string to a pencil and lay the pencil across the opening of the jar. The string should be just long enough so that it reaches to just above the water/salt mixture.
- 4). Let the jar sit until the water evaporates and the salt crystals form on the piece of string. This takes about three weeks.
