Rock Candy
from Cookie's Place

Rock candy is a fabulous way to see what crystals are about. Rock candy is just crystallized sugar. This project is intended for parents. They should share it with their children because it involves cooking sugars at dangerous temperatures hot enough to burn or hurt children very, very badly. Kids absolutely need their family's help and permission to do this project !

WHAT YOU NEED: 2 cup water - 5 cups sugar - pie pan - string or bamboo skewer - grown-up - candy thermometer - foil - patience

WHAT TO DO: Stretch the string across a pie pan so that it is suspended across the top. You'll have to weight the ends so that it does not touch the bottom of the pan. Or You Can punch holes in the edge of the pan and tie the string. You Can also lay a skewer across and out the pan like in the drawing.

MORE STUFF: Dissolve the sugar in the water and cook until it reaches 250°. This temperature is also called hard ball, and most cookbooks will tell you how to do it without a candy thermometer. Don't stir after you've dissolved the sugar.

EVEN MORE STUFF: Pour the hot liquid into the pan. The string should be 3/4 inch under the surface of the sugar water. Cover the pan with foil and don't touch it for a whole week. In 7 days, lift out the string or stick and it will be covered with sugar crystals!

You Can also pour the liquid into a jar. Punch a bamboo skewer through a plastic coffee-can lid. Lay the lid over the jar so the skewer hangs down the middle of the liquid. Do not let the skewer touch the bottom of the jar. In 7 days, lift out the skewer and it will be covered with sugar crystals!
