To get the bucket to rotate, I would move the time scrubber to the point in the timeline where the bucket should have maximum rotation, then rotate it how you want it. If you are using auto keyframe it should sort itself out. If you are keyframing manually, then add a keyframe >for rotation at that point with the bucket selected. But to get thew bucket to rotate about what point? It wants to rotate about its own centre. I need to alter that accurately.
