After centrifuging a large amount of redstone, we're left with at least a stack of mercury cells. Is there anyway of emptying those cells and saving the mercury for later?
Any method that consumes the cells isn't acceptable, and we should be able to put mercury back in the cells later.
(Running Unhinged, so be aware that some things are more expensive than others. If the only answer is a liquid tesseract, I might just give up. :P )
