The night before the party cut up all of your fruit (melons, apples, oranges and strawberries) and put them into a 10 gal water cooler. Pour in your juice and alcohol at the same time and mix. Let it sit overnight so that the fruit can absorb some of the alcohol. The vodka is simply for taste so that you don't kill anyone. Without it the Jungle Juice will taste like it has no alcohol at all.
