Place 1/2 cup ice cubes in a tall glass (at least 16 oz.). Add 1/2 cup chilled chocolate- or strawberry-flavor milk, then pour in 3/4 cup chilled orange soda. Sprinkle with long, thin orange peel strands and finely chopped semisweet chocolate to taste. Stir, and sip immediately through a straw (soda loses its fizz quickly).
