If you put random objects (marbles, footballs, etc) into a tube, how would you count them (electronically) in the tube

So long as there is some distinct boudary between the objects - whatever they are - you can detect that boundard and, thus, count the objects.

"Detecting the boundary" is, of course, the key requirement - and may well not be trivial. This seemed to be the focus of the opening post.

I see no way to electrinically count the contents once they are in the tube

It just means that you have to somehow "scan" the tube to look for the gaps.
