At the grocery store you pick up a can of beef broth and a can of chunky beef stew. The cans are identical in diameter and weight. Rolling both of them down the aisle with the same initial speed, you notice that the can of chunky stew rolls much farther than the can of broth. Why?

I would expect the consistency of the stew to be much thicker than that of the soup (maybe even to the point of it being a jelly). So when you roll the cans, the con of stew behaves as if it was a solid object. The soup, on the other hand, is a cylinder with a fluid inside. When you roll this can, the can will rotate as it moves across the floor, but not all of the contents will move at the same rate. This generates eddies within the fluid act as a brake.

It has to do with the uneven or heterogenous mixture of the stew vs the homogenous, even mixture of the broth. The heavier part of the stew, through centripetal force, accelerates the can faster than the uniform rolling motion of the can of broth.
