Combine 8 cups water with sugar and boil for 15 minutes let cool. Mix orange juice with 12 cans of water to dilute it. Puree bananas in blender with a little of the diluted oj.
When water and sugar have cooled add all the ingredients except ginger ale. I freeze mine in gallon or 1/2 gallon milk cartons. Take out of the freezer about 3 or 4 hours before serving and pour ginger ale over it.
