It is fair to say that this is easier to do if you can juggle, but juggling isn't the only required skill of Flair. This is harder to practice, compared to making and tasting cocktails, especially as it may involve flying bottles, glasses or shakers. As this is a skill I'm still trying to develop, my best suggestions are use a previously finished standard sized/shaped bottle, filled with water; ensure you have plenty of room and preferably a soft flooring (i.e. not stone) and lastly, don't have any pets or small children running around while you're trying to copy anything you may have watched on a video or at your local TGI Friday's...
