How to make a Watermelon Keg.
Wash the watermelon and gently remove the top. Then scoop out the watermelon flesh. Just like carving a pumpkin—only wetter—scoop out as much flesh as possible with an ice cream scoop or large spoon. Make a hole toward the bottom portion of the watermelon using an apple corer. A hole approximately two to three inches (5 to 7.5cm) from the base of the watermelon is appropriate. Make the keg hole the same size as the spigot line. You will want to fit the spigot snugly into the hole created by the corer, but not so large that a gap is created. Fill the fruit keg with your favorite punch recipe. A punch recipe that infuses watermelon or watermelon flavors would be most desirable, but any punch recipe will work.
side note: you know, if alcohol isnt for you, you can fill this thing with lemonade or water or something instead. Don’t hate.
