The easiest way to make crystals is to fill up a tall cup of warm water with lots of table salt dissolved in it. Take a piece of thick string or yarn, tie it in the middle of a pencil. Suspend the string into a cup of water by placing the pencil across the cup. As the water evaporates every days you'll see crystals forming on the string.
