It's not entirely clear what you're trying to do but it would seem that this could be accomplished with chromakey, or a mask and key framing. Shoot the background. Shoot the floating object against a background that you can key out or make transparant, or create a mask to isolate the floating object. Then keyframe the object to move as required. No need to levitate, use strings, etc.
