1Bring the water to a boil in a saucepan. Remove from heat and add 3 cups of sugar, stirring until dissolved. Slowly add the remaining sugar, reheating the water if necessary.
When all the sugar has dissolved, pour the mixture into 3 heat proof jars or glasses. Stir 3 drops of liquid food color and 1/2 t. of flavoring into each jars.
Tie a piece of string around a pencil. Lay the pencil over the rim of the jar so that the string is dangling in the glass, into the liquid.
Crystals will begin to form in a hour and continue for several days.
If a layer forms on the surface of the jar, break it. When the liquid has evaporated completely the candy is ready.
