Why, when you rotate a glass of liquid with ice cubes in it, does the ice not rotate with the cup?
Inertia. Everything in the universe is trying to carry on the way it is – moving or stationary. When you push yourself across the floor on your office chair (don't pretend you don't) when you stop pushing, you carry on.
The Short Answer
Inertia. Everything in the universe is trying to carry on the way it is – moving or stationary. When you push yourself across the floor on your office chair (don't pretend you don't) when you stop pushing, you carry on. When you push the glass round, the ice wants to stay still. There's very little friction between the cup and the ice – so there's not much force pushing it round.
