Steps
1
Start a pot of water boiling on the stove.2
Twist a piece of cotton string (or a pipe cleaner) around the middle of the stick. The cotton string should be long enough so that when the stick is placed over the top of the glass, the string will hang just short of the bottom.3
Wet the string with a little water and roll it in the sugar.4
Lay the stick over the top of the glass jar so that the string hangs down inside the jar, but doesn't touch the bottom of the jar.5
When the water has started boiling, remove it from the heat and let the water settle.6
Stir in the sugar one half cup at a time. Continue adding the sugar until it starts collecting at the bottom of the pot and will not dissolve even when you stir. This will take a while and a good bit of sugar but not too much.7
If you want to add flavoring or color, stir it in now.8
Pour the sugary syrup solution into the glass until it is about 1 inch (2.5cm) from the top.9
Place the pencil over the jar and allow the string to dangle into the solution. Don't let the string settle on the bottom or sides of the glass.10
Place the glass somewhere where it can sit for a while undisturbed (but do not refrigerate it). After a day or so, you should start to see crystal growth forming on the string.11
Leave the string in the solution until the crystals are big enough for your liking or they have completely stopped growing.12
Remove the string from the glass and let dry.13
After it dries, wait until the crystal is formed and ready. You have a choice now to either eat the rock candy or keep it."For this one credit goes to wiki how
