Chocolate Popcorn Fudge

Combine water, sugar, corn syrup, and chocolate in a saucepan, and cook, stirring, until chocolate melts. Bring to a boil gently until candy reaches 254 on a candy thermometer. Pour candy over candy over warm popped corn in a big bowl. Stir with a spoon to coat all the corn. Butter your hands and working fast, shape the popcorn into candy-bar shapes (long, round or flat, as you wish). Wrap your candy bars in foil or plastic wrap.
