  1. 1

    Place a glass jar onto a flat surface. Pour 2 cups of sea salt into the jar. You can find sea salt at any grocery store or supermarket.

  2. 2

    Pour 3 cups of water into the jar, and stir the mixture with a spoon to help the sea salt dissolve.

  3. 3

    Cut a piece of twine that measures the length of the glass jar, and tie the twine onto an unsharpened pencil.

  4. 4

    Place the end of the twine into the salty water, and rest the pencil across the open top of the jar. The twine should be hanging in the water.

  5. 5

    Place the glass jar into a sunny location, and leave it undisturbed for 3 days. The water will evaporate from the jar, leaving large crystals of sea salt attached to the twine.
