You're welcome, brother. It's that exact 'mad scientist macguffin' vibe I wish I had more of in toy form.
Hey, speaking of... nab one of the Ready2Robot kits if you can, full-price if need be. The figure and goo effect is NBD but the container itself is a very nice sci-fi pod if you need cargo containers, field generators, etc. It separates into 4 levels from the bottom up (each level dropping off releases pressure on the tabs that lock the next level in place) with the 04 top level having a pop-off lid for the the goo container (you press up from the bottom to literally pop the lid off) with its own pop-off lid for the goo with the pilot minifigure drowning in it. Apologies for the thoughtless lack of scale-comparison pics, but the completed pod is right about a 4" figure's height.

Each pod comes with two like-colored tabs to connect to other pods hexagonally. I have two lighter-colored pods I've stolen tabs from:
Ignore the parts in level 01, they're also from a custom:
