You are going to need a lit subject a shutter speeds this high don't allow your camera much time to gather light for exposure. You can get this to a degree by using a higher ISO setting , but don't get to high, or the noise will creep into your shot.
One of the effects moving water will look smooth and silky when shot at shutter speeds of 1/8 of a second or more - the longer the exposure the pronounced the effect .
