Place popped corn in a mixing bowl; set aside. In a small saucepan, over medium-high heat, bring sugar, corn syrup, water, margarine, and salt to a boil. Cook, stirring, until sugar dissolves. Cook, without stirring, for ten minutes or until it reaches hard-ball stage of 254 on the candy thermometer. Remove from heat. Wearing oven mitts to shield against splatters, carefully stir in vanilla extract. Pour over popped corn; using a prepared spoon, toss until well coated. Stir in orange candies. Form into two-inch balls; let cool on a baking sheet.
