This is an actual animation function so the timeline will probably need to be extended beyond the default 4 seconds to get satisfactory results. The Render Output Option will need to be set to "Current Frame" unless you actually want to render a movie. 

Additionally, physics, especially with more complex shapes like the "S" shape may need some of the physics properties adjusted to interact with each other correctly. This is performed in the Scene portion of the Properties Tab - it's best to adjust only the Geometry Fidelity tab first, even up to 100%, before moving the other sliders. 

Hope this helps!
