How to Make Sea Salt Crystals for Science Project


Sea salt is harvested from sea water, and can often be found naturally growing in larger clusters or clumps. Kids can grow their own salt crystal clumps using a few kitchen materials.

Things You'll Need

  • Glass jar
  • Sea salt
  • Distilled water
  • Spoon
  • Twine
  • Scissors
  • Pencil
  • 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.

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

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

  • 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.

  • 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.
