rock candy

i remember doing this for a science project when i was a kid, and thought it would be fun for my kids as well. trevor decided he wanted to make yellow rock candy, but since it hardens much lighter in color than the liquid, i made our syrup orange. worst case is we have orange candy instead of yellow, but i have a feeling we'll end up w/a golden yellow. here's our starting point:


to make your own rock candy, boil 1 c water. add sugar a little at a time till it won't dissolve any more (ours took about 2 1/2 cups). add food coloring if you want - make it darker than you want your candy; i'm expecting ours will harden as a very light orange or deep, golden yellow. let the syrup cool for about 20 minutes. put a clothespin on a skewer or other stick so that when rested across the top of your glass or jar, the end of the skewer is about 1 inch from the bottom. dip the skewer in the syrup, then roll in sugar (this is your "seed"). let it dry completely. pour syrup into your glass or jar till it's almost to the top, then place your skewer in the solution. make sure the skewer is completely vertical and doesn't touch the bottom or sides. leave the glass or jar undisturbed for a few days, and soon you'll see crystals starting to form!
