01 - If desired, rim each champagne flute or glass with lemon juice and dip in edible glitter or gold sugar for a decorative finish.
02 - In a large pitcher, combine sparkling white grape juice, sparkling raspberry or strawberry soda, cranberry juice, and lemon juice. Stir gently to mix while preserving carbonation.
03 - Fill each champagne flute or cocktail glass about three-quarters full with the mocktail mixture, leaving room for the cotton candy garnish.
04 - Just before serving, place a small tuft of pink cotton candy on top of each glass. The cotton candy will dissolve when the drink is poured over it or as the drink is sipped, adding sweetness and a dramatic visual effect.
05 - Garnish with fresh raspberries or strawberries if desired. Serve immediately while the cotton candy is still fluffy and the drinks are well-chilled.
