You can easily double or triple this recipe as long as you keep the proportions the same. Just use a larger punch bowl. Open a 16-ounce (473 ml) bottle of Mountain Dew, Mello Yello, or Sprite and pour it into the Coca-Cola in the punch bowl. Pour slowly to prevent the soda from fizzing up a lot. Open and pour in a 16-ounce (473 ml) bottle of cream soda. Take a long spoon and slowly stir the mixture until the liquids are combined. Set out serving glasses so guests can help themselves to this fizzy drink. If you'd like to put the cola in bottles, use a funnel to pour it into the bottles and serve them before the Nuka cola loses its carbonation. If you choose to bottle the Nuka cola, consider setting out some old Nuka Cola Caps.
