Conclusion:

The ice cube will start to spin faster and faster until it is turning much faster then the water around it. This occurs because the melting ice causes water to sink underneath it. This in turn draws in some of the warm water from the top edges. The water coming in from the edges is what spins the ice cube faster. This is the same principle that causes tornados and whirlpools.
