Make Rock Candy
Making rock candy - which is actually just sugar crystals on a string - can be a remarkably enjoyable and edible science project, as well as a tasty treat. Follow these simple steps to have a batch ready in no time. Add this to my Recipe Box.
Instructions
1. Sterilize the glass jar and paper clip by boiling both in water for a few minutes.
2. Tie a short piece of kitchen string to the middle of a pencil or Popsicle stick.
3. Attach the paper clip to the end of string. (The clip will weigh the string down - this is important later.)
4. Moisten string lightly and roll in sugar (this helps the crystals form on the string).
5. Place the pencil or stick over top of a jar. Make sure clip is in the bottom of jar and the string hangs straight down into jar.
6. Heat 1 cup water to boil.
7. Dissolve 2 cups sugar in boiling water.
8. Add a few drops food coloring if you like.
9. Pour sugar syrup into jar and leave for 2 to 3 days or until crystals form on the string.
