You can try to put a coin down in front of the ball and try to hit the ball and the coin. I have tried this before but the problem with this kind of advice is, it does not help you with what you need to do to hit the ball first. Kind of like the advice of swing to right field to help hit a draw. Just advice that tells you what needs to be done, the hard part is the how. I'm not good enough to help with the how.
