I got one because I was intrigued by its lead rotation, but I found that it really didn't rotate the lead enough while I wrote. I kept having to rotate the barrel manually to keep a thin line like I do for every other mechanical pencil, and then would get annoyed every time the clip came around to brush my hand. I've been wondering if I'm doing something wrong, or if Japanese just uses more shorter strokes. Do you also like it when writing English?

Arsenic is a classic murder poison. It's been known since anciemt times, though possibly unsuited to your onset requirement. Acute poisoning by ingestion is generally within a few hours, but if your character sustains lower doses over time, you could probably draw out the timeline to whatever you wanted. It would be obvious that the character is unwell during this time, but the symptoms aren't super specific and could be confused with e.g. food poisoning.

Or just invent a mushroom like others said. The toxins are diverse enough that I doubt anyone would be too upset if you tuned it exactly to your timeline and desired symptoms.

Cyanide poisoning is famously pretty fast though...

If those undergrads could figure out how to turn acetone into TNT...

EHS would raise hell if they caught us putting waste solvent in anything but a hazardous waste container...

What a coincidence, the end of my support for windows is also approaching.

jk I scrubbed that shit from my personal devices years ago after graduating.

Hey look, it's a kürzlich aufgebauter vom Aufbauprinzip verbauter Bau

Edit: also, the configuration is referring to silver for those curious. Not my first choice, but whatever floats OP's boat (Baute?) I suppose.

The intended joke is that hypervalent iodine compounds like Dess-Martin periodinane flip between different oxidation states like you often see for transition metals. As an example, the mechanism usually drawn for oxidations by DMP is similar to those drawn for PCC/Jones reagent, where the electrons removed from the substrate are "banked" at the metal center. Obviously, redox chemistry is not at all limited to transition metals, but I am often surprised at iodine's propensity to engage in it. A lot of research over the past decade or two has also developed redox catalysis with these reagents, reactivity which is commonly (though again not always) the purview of transition metals.

Iodine is a transition metal I will die on this hill.

Nah fam, people like that are the reason we had to evacuate the dorms every month or so in the middle of the night during the winter months.

That and idiots making toast. Not sure how people routinely fucked that up so badly.
