Buy a Watermelon Tap Here! A very unique idea for party hosting. Hollow out your watermelon or pumpkin, then stab this sucker into the side of the melon. Then you can add any type of beverage to the inside and start using it like a keg tap. The best part is that you can just compost the watermelon when you are done and therefore, no jugs to clean. It's a great ice breaker and the kids would really like it.
