Yes. If I recall, I originally read about it in Dave Pelz book Putt Like the Pros. You float and spin a golf ball in a salt/water solution and the ball will eventually balance out with the heaviest area at the bottom. You then make a mark with a sharpe on the heaviest spot*. The idea then is to place the ball on the ground with the spot on the bottom so the ball will roll end over end and stay on line better. If the heavy spot is not placed end over end, it could cause the ball to move off line because it is lop-sided and out of balance. That’s the best of my recollection.
* You could also draw a line around the circumference through the heaviest spot.
