A Multiplayer Game For Dogs

DogScientist built a mechanical game for his dogs. Was this project just to give the dogs something to do? To make them put a little effort into feeding? Or is it a lesson in figuring out challenges? It doesn't really matter, because all those ends are accomplished as the dogs learn how the machine works, and then learn strategies to make it work better for them. And it's pretty neat to watch, too. (via Tastefully Offensive)
