Lots of empty beer bottles + lots of extra time + lots of space = beer bottle dominoes. In this video taken at Cafeen in Denmark, hundreds of bottles topple over, seemingly without any purpose, until the end when the last bottle falls over and it turns out it's a Rube Goldberg machine—which still means it doesn't have much of a purpose. But at least it looks cool and makes fun clinking sounds. Watch the video after the jump.
