This awesomely elaborate beer bong takes the fun and drinking involved with a normal and adds a facet of gambling and chance. It’s got a spinning mechanism built into it. When you wrap your lips around that tube of destruction, you spin the “roulette” part of the mechanism, and you’re afforded a chance to either not drink, or drink 2 litres of beer. For now, it's just a concept, but soon you'll be able to hold this barrel to your head. Cheers!
