Just as a 5-liter keg of beer is not uncommon at a picnic or summer party, neither is a watermelon. But why always serve it in the conventional way, cut into pieces or slices, when you can serve it like beer from a keg. Well, beer and watermelon still don't go together, so you can make a keg out of a watermelon rind and pour draft watermelon out of it through a spigot.
