The bottle is smaller in diameter than that of the hole so this drill will also sharpen your ability to be more accurate over short putts. Now place the bottle in a hole on the green and again bounce the ball off the bottle from two, four and then six feet. Take this drill on the course when playing competitively by using imagination and feel to visualise every putt from six feet simply bouncing off the bottle.
The result will be a much more confident stroke and more holed putts.
