If you're juicing your own grapefruit and oranges to make this drink, be sure to use a juicer that will catch the pulp, so it won't go into the final drink. (Grapefruit is quite pulpy!)
Fill two 12-ounce glasses with ice, and add a 1/4 cup of orange juice, a 1/4 cup of grapefruit juice, and a 1/4 cup of sparkling water to each glass. Garnish with extra slices of grapefruit, or a slice of lime, to complete the drink. Serve right away for the best flavor; the ice will start to dilute the sweetness as it melts.
