Frosty Fireworks (Non-Alcoholic 4Th Of July Drink)

["Fill the sections of one ice cube tray with blue Gatorade, and place in freezer for several hours or until frozen solid.", "Fill the sections of the other ice cube tray with the red Gatorade (or other red color drink), and place in freezer until frozen solid.", "When ready to serve, place about 4 or 5 regular (clear) ice cubes in a highball glass or tall tumbler.", "Add two blue ice cubes and two red ice cubes to the glass.", "Fill the glass the rest of the way with a clear carbonated soda. I prefer Sprite, but you can use 7-Up, Club Soda, Seltzer water (or try a fruit flavored seltzer), or your favorite lemon-lime soda.", "Now wait to see the special effects to begin. As the cubes melt, colored bubbles will swirl through the soda and create a sparkling ""frosty fireworks"" effect."]
