There are days I think I would like to clarify what is happening.  But that is often more difficult that it would seem.  You can’t just tie a string around it and then measure the distance it ranges and then calculate the circumference of the sphere it describes and therefore the volume and have that mean anything.  Perhaps it would mean something because you could record the volume from day to day and it would change and then you could graph the change in volume from day to day or merely the volume or the vector of the string…the velocity…
