Science Wonders Home Grown Crystals

Our sugar crystals we were growning are done. We found this idea in "Try-Its for Brownie Girl Scouts" book pages 130-131. The recipe was a little unclear so a search revealed a great recipe at Camryn was fascinated with hers and wanted to save the best looking crystal group from her string.Aaron added food coloring so they could each tell wich was their crystal jar. Here is the recipe if you want to try-it too.
Rock Candy
4 cups sugar
2 cups water few drops food coloring
small clean glass jar cotton string
waxed paper (we used ziploc baggies upside down over the jars)
tip:dip the string in a sugar syrup and let dry a few days to make better crystals(we let ours dry overnight)
Bring the water to a boil slowly add sugar stirring to disolve it a little at a time. When cooled at little pour into glass jar. Add foood coloring if you want. Hang string over jar from a straw or pencil. Let set and watch.
Our crystals grew really big. They look like those candies you find on wooden sticks in novelty stores.
Science you can eat!
