On setting it upright the final time, we could bleed off the liquid into an expansion chamber and then to atmosphere, leaving behind the oil.
Clamp on band heaters turn the dry ice to liquid, which is circulated and soaked through the material by simply turning the cylinder upside down.
I could calculate the practicality of it, if anyone is really interested, I'd have to do some serious chemistry.
I added a bubbler to the system.
