I am building some custom lab equipment for our new Frankenstein scene this year. One of the machines I am planning would have three clear cylinders on top, two smaller ones on each side and a large in the middle. I would like to have the fluid level in the two outer cylinders drop (drain out) as the large cylinder in the middle bubbles more and lighting changes, etc.
Does anyone have any ideas on how to handle the fluid transfer? I was wondering about skipping the pump idea and having a reservoir below the smaller cylinders with a piston type arrangement on a cylinder... as the cylinder retracted it would make room in the reservoir to allow the fluid to drain out of the cylinder above and when it extended, it would push the fluid back up into the cylinder... but how would I seal something like that to avoid leaks? Anyone have ideas?
