My bubbles dont seem to be getting any smaller as they reach the top though,
(as i observed at the LFS).


Mine didn't either, until I fiddled with it.

I pushed the bubble stair-case down an inch and at a slightest of
angle.

Now the bubbles reduce in half...then in half again before exiting.
(Enter as a bean and leave as half-BBs).

The bubbles move much slower as well. I have 4 or 5 bubbles in the
device at the same time.
