In a large pitcher, combine the lemonade and coconut water. Stir well to mix.
Slowly pour in the sparkling water, being careful not to lose too much carbonation.
In individual glasses, add a tablespoon of blue raspberry syrup to the bottom of each glass.
Fill each glass with ice cubes, then pour the lemonade mixture over the ice, filling the glass about three-quarters full.
Carefully drizzle a tablespoon of grenadine into each glass. It will sink to the bottom, creating a beautiful layered effect.
Garnish each glass with a slice of lemon and a sprinkle of edible glitter for a magical touch.
Serve immediately and enjoy the colorful, refreshing drink!
