%95 4 cups sugar
%95 2 cups water
%95 a small saucepan
%95 a wooden spoon
%95 a candy thermometer
%95 a small, clean glass jar
%95 a measuring cup
%95 cotton string
%95 a weight to hang on the string (such as a screw or galvanized washer)
%95 waxed paper
%95 a pencil (to suspend the string in the jar)
1. Heat the water in the saucepan over medium-high heat until it comes to a boil.
2. Completely dissolve the sugar in the boiling water, stirring continuously with the wooden spoon until the solution grows clear and it reaches the hard-ball stage, or about 247%B0 F%96252%B0 F.
3. Remove the solution from the heat, let it cool to room temperature, and then carefully pour it into the jar. Cover the jar with a small piece of waxed paper.
4. Tie the weight to one end of the string, and then tie the other end to the middle of the pencil. The string should be about two-thirds as long as the jar is deep. Dip the string into the sugar solution, remove it, lay it on a piece of waxed paper, straighten it out, and let it dry for a few days.
