So I am rectifying this

Oh nice!!! I love rectification of this kind!

Spoiler

And of another kind of course: In our PChem lab for second year students, we do fractional distillation (some call rectification) of a three component mixture of liquids having close boiling points. When I actively ;) took such a lab 40 years ago, uhm, we exchanged the multi-component mixture with denaturated ethanol. Back then, pyridine was frequently used the denaturation compound. Well, the 2 m rectification column in the PChem lab was well suited to quantitatively separate these two, resulting in a 96% ethanol/H2O mixture. Upon addition of some tonic water etc. ...

Thank you very much, Evan!
All the best

You're welcome.

A few weeks ago I happened to see on Facebook Marketplace that someone a couple of hours from me was selling a massive haul of Dacta sets. He wanted a substantial sum. We negotiated a deal and I drove out there. I don't need most of the sets (so I'm trying to sell them: https://www.eurobricks.com/forum/forums/topic/212437-fs-several-early-dacta-sets/) ... mostly I was willing to lay out the money because his stash of rare Lego educational manuals was overwhelming.
