Cats Help Complete a Chain Reaction

We've seen a lot of domino falls, marble runs, and chain reactions on the internet. I always have to wonder what happens when a complicated run just stops for no discernible reason. Do you start all over or edit the video? One way to keep things going is to enlist the help of cats! But these aren't just any cats, they are the trained cats of Cat Navi Desk, although you may glean from the video that some are better trained than others. In this domino/marble run/Rube Goldberg contraption, they are ready to help whenever the chain goes awry. I'm not convinced that this is one smooth run, but it doesn't really matter because it's so darn entertaining. (via Geeks Are Sexy)
