Not Quite correct. The bottle must NOT cross the parallel to the ground clubshaft position at the top. preferably a little short of that. It'll make sure that your swing is one CONTINOUS motion. If you stop the swing the water will come to the cap. Simple principle of sustained centrifugal accelleration. Dont forget you create centrifugal force in the backswing too. The secret is to maintain it through the swing uninterrupted.

Consider that the bottle is standing normally on the ground. Pick it up with both hands as while gripping a club. Swing away without letting the water touch the cap. Use one hand at a time if you want to.

Do you advocate using the water bottle filled 1/4 water and try without the cap? Instant feedback!

Also where did you attach the bottle to the shaft? Near the hands, in the middle, or at the end to simulate a clubhead? Or does it matter?

Thanks much.

Thanks, I think I get it now. The cap represents the butt end of the club and the cap will point at the plane line at some point in the backswing, correct?
