This object is kind of complex with all the details and measurements. One of the challenges I resolved was the ability to stop the pool ball from rolling off from the base by creating a basin with the ripples.
Now the pool ball creates a sense of something planetary because of the new possibility of rotation around the bottle. The result is a ludic and beautiful element added for the solitary drinker who now can give wings to his thinking. The ashtray inner ripple serves as a stop for the base of the decanter.
