Lengthy of the video and shaky camera skills aside, this is a pretty good Rube Goldberg machine. And best of all, the purpose of the machine is to pour a beer. Unfortunately the beer may be warm by the time it is actually poured. Unless you want to see an overview of an entire contraption, skip to about 2:10 into the movie to see the machine function.
