　　Kids will need no explanation: They will marvel at these red-and-green-striped drinks that they swirl with a straw. And for grown-ups who may want to get in on the fun, you can make another batch—a shot of gin makes a pleasant, and civilized, addition.

Ingredients

　　1 1/4 cups lime syrup

　　3 ounces grenadine

　　2 liters chilled lemon-lime seltzer or club soda

　　Garnish: maraschino cherries

　　Pour 2 tablespoons lime syrup into each of 10 tall (8-ounce) glasses. Carefully pour 1 tablespoon grenadine over back of a long spoon inserted halfway into each glass (to prevent colors from blending). Gently top off drinks with seltzer, pouring it over back of spoon.
