Ingredients

1 Clean glass jar (a large mason jar would be great!)
1 Piece of string (cotton)
1 Pencil or stick
1 Large paper clip
3 cups Sugar + additional sugar
1 cup Water
Food coloring
An adult heats the water to boiling, and when the water stops boiling dissolve the 3 cups of sugar into it. Let cool some and reheat (Do Not Re-boil) and add as much sugar that will dissolve. Add a few drops of food coloring to the sugar water. Let cool for two minutes and an adult pours the solution into glass or jar. Tie a short piece of cotton string to the middle of the pencil or stick. Attach a paper clip to the end of the string for a weight. Moisten the string very lightly, and roll in a bit of sugar Place the pencil or stick over the top of the glass or jar with the string hanging down inside. Leave undisturbed for a couple of days. Have the children watch what happens!!! After the candy grows, let the children sample their edible rocks!!
