It would be interesting to do the Sagnac Experiment on Saturn. Its 360,000 km circumference rotating in 10 hours is doing a whopping 36,000 kph (compared to the Earth's 1600kph): that's one hell of an interference fringe! Is any planet rotating on its axis faster?

Why, Jupiter, of course!

Is there a limit to how fast a planet can rotate?

I'm sure there is at the point that the rotational energy exceeds the binding forces of the planet it would basically fly apart and disintegrate. Or rather would probably never really integrate in the first place.
