It's about time technology progressed far enough for one to serve liquor out of fruit; the watermelon keg is literally a watermelon with a spigot attached to it.
Lovers of cool patio nights and a good, refreshing alcoholic beverage, the watermelon keg is all you need. All one does is hollow out a watermelon, attach a spigot and fill the melon's husk with some ice-cold punch; you simply start pouring cups of refreshing watermelon vodka and let the good times flow. The watermelon keg will make drinking at the beach a much more natural activity and erase the need for lugging around heavy metal kegs as well.
Ultimately, the watermelon keg is perfect for those balmy nights.
