Put It All Together

[Photograph of a jar filled with saline solution, a paperclip suspended on a string from a pencil resting on the jar. A paper towel is on the jar to prevent dust from falling in.] Lower the paper clip and string into the water and rest the pencil across the top of the jar. Cover the jar lightly with a paper towel. This will keep dust out of the jar. Place the jar where it won't be disturbed for a couple of days.

Table salt (halite) crystals form as cubes. After about 12 hours, you should be able to see small crystals forming at the bottom of the jar, on the paper clip, and along the string. Some may even form on the surface of the water, like a wreath around the string. After 24 hours, you should see definite crystal forms.

After all this work, let's see the results and how to find out more about minerals.
