Summary
OK Go's most famous video: a two-story Rube Goldberg machine that fills a warehouse and plays out in one continuous take, perfectly timed to the song. Balls roll, dominoes fall, and one action triggers the next in a long chain of simple machines. The anchor video for the Sandbox's cause-and-effect and energy lessons.
