Couldn't you just drop BBs into the largest chambers to bring them down to
the smallest?

Dear Jim,

I don't understand.

The initial goal is to determine the volume of the LARGEST cylinder.
The marble trick allows us to measure a volume that is GREATER than
the 50cc volume of our syringe.

For example, let's assume our marbles are equal to 20cc. We dry the
marbles, place them in the chamber to be measured, install the cover
plate then fill the chamber with fluid. If it takes 37cc of fluid to
fill the chamber then its actual volume will be 57cc. I don't see any
benefit from using BB's. In fact, I can imagine several situations
where the BB's would be a real PTA to work with.

But I'm always willing to learn, especially from someone with your
credentials.
