Cotton Wool Ball Shotput

This is a new event, so if you do it, please tell me the size of the coton wool ball.

Contestants stand with their feet behind a line. They flip, throw, spin, toss the cotton wool balls across an open space. The distance measured is where the ball ENDS UP (not necessarily where it lands) to the throwing line. Cotton Wool balls cannot be torn, bent, folded or changed in any other way, and cannot have anything added to them, especially not water or any other liquid.
