If you really stop to consider it the origin of almost every sport evolved from someone who had something that had to do or someone who didn't have enough to do. This sport appears to fall under the heading of the latter.

I started watching this video with an attitude of what kind of horse pucky is this? The longer I watched, the more deeply engaged I became. I found myself genuinely excited by the action on the track. The sport is called Sand Marble Racing.

I'd like to think that this sport was conceived somewhere once upon a time in a sandbox by a child who had a vivid imagination. It's this kind of way out the box thought that will eventually bring us to a solution to life's bigger issues.

Or,  it could just be a bunch of guys who had some cameras, a beach, and maybe a few beers and thought this would be a great way to become "Internet Famous".
