Chemists get another solid pummeling from xkcd dot com. Also, double question marks, very Ryan North. [[User:Lightcaller|Lightcaller]] ([[User talk:Lightcaller|talk]]) 00:41, 17 October 2020 (UTC)

You could disguise the smell of your rotten eggs with [https://blogs.sciencemag.org/pipeline/archives/2012/05/15/things_i_wont_work_with_selenophenol selenophenol] and [https://blogs.sciencemag.org/pipeline/archives/2009/06/11/things_i_wont_work_with_thioacetone thioacetones]. Nobody will complain about your mere sulphides then... (ETA: I wonder about selenoacetones?)[[Special:Contributions/162.158.154.167|162.158.154.167]] 00:53, 17 October 2020 (UTC)

Seperately, I recall the time when I was still at school and we'd made some compound that had produced the distinct smell of almonds. Mentioning this later to my father (a chemist himself) he was initially quite concerned before I clarified whatever-it-was as whatever it actually was and not an actual cyanogen compound.

I always heave a mental sigh when I see some bit of safety literature informing me that natural gas smells like rotten eggs.  First, as Randall points out, that's not a very useful explanation for most people.  Second, it isn't the natural gas (i.e. methane) that has that odour, but the thiols that are added to it as a safety feature.

Pretty sure the current version explanation is wildly overthinking this - sometimes a cigar is just a cigar, and sometimes a comic about how weird it is that we reference things smelling like rotten eggs when they’re uncommon is just that.

Actually, sulphides (H2S in particular) smell more like farts that rotten eggs.  But science teachers know that if they use the word "fart" in front of a class, there will be no more work done in that lesson, and probably none by that class. 

The kids recognise the smell, of course.  We used to call it "fartrogen dioxide". Paul Seed 07:43, 17 October 2020 (UTC)

I read that the principal components of flatus ("fart gas") are methyl mercaptan, dimethyl sulfide, and hydrogen sulfide, leading to [ahem] a complex cocktail of odors. https://en.wikipedia.org/wiki/Flatulence#Production,_composition,_and_smell

There was a time, before refrigeration or stock rotation, when bad eggs were much more common.  Hence the story of the Curate's egg [https://en.wikipedia.org/wiki/Curate%27s_egg], updated here [https://twitter.com/VictorianHumour/status/1014537505587302400]

The Halloween reference could use an explanation. I don't live in the US (or wherever Halloween tradition lives), and connection to eggs is not clear to me. [[Special:Contributions/162.158.183.152|162.158.183.152]] 08:21, 17 October 2020 (UTC)

Rotten eggs were a common feature of the household that had free-range chickens and small children. The hens would lay their eggs in whatever spot pleased them, rather than just in the hen house. Children sent out to collect eggs would delight in finding eggs that had lain hidden for weeks and bring them in to the kitchen where Mother would carefully crack eggs separately, as mentioned in the explanation.

:I think that everyone could find egg which was hidden longer than expected, not just small children. Also, the ratio of households with children didn't changed much, while the ratio of households with free-range chickens dropped massively. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 01:42, 18 October 2020 (UTC)

I think that the section at the top seems to fit more in trivia rather than directly as a comic explanation because it doesn't really explain the comic [[Special:Contributions/108.162.212.29|108.162.212.29]] 14:16, 17 October 2020 (UTC)Anonymous

Anecdote, and not hydrogen sulfide or (primarily) smell, but related: Scene - a chemistry class being taught by ill-prepared/scatty teacher. Instructions to the class being read out from a book from the front. Flasks on the tripods on desks, ready for the next bit, which was apparently something like "add 2cc of bromine"... Duly added by all the class. Turns page ..."water.". Too much! Boil off a little everybody! Boiling off creates carpet of brown fumes roiling across the floor. Question from a pupil - isn't bromine poisonous? Yes, yes! Deadly (sic) poison! Evacuate the class! - Which, because it was on the top floor and the brown mist was now out of the door and flowing down the stairs meant a far more thorough evacuation of the entire building...

Further anecdote, less related, was when nitration of toluene went a bit far. Instead of being creamy-yellow it was white (or vice-versa - I forget which), so it wasn't nitrotoluene any more. Apparently there was an area in the school fields where they buried (or at least saved for possible later analysis) such things as test-tubes of suspected trinitrotoluene, to which this was (gently!) whisked away.

So then, what does sulfur smell like, if not rotten eggs? What's a better descriptor? [[Special:Contributions/162.158.78.198|162.158.78.198]] 02:03, 21 October 2020 (UTC)
:Farts. Unlike rotten eggs, most students will have encountered these.  And, depending on their diet,  it may even be accurate. [[Special:Contributions/162.158.38.22|162.158.38.22]] 21:41, 27 October 2020 (UTC)

You don't need to encounter rotten eggs to figure out the smell, any stale egg dish will do. Like an omelette that's been sitting out for just too long.[[User:Xurkitree10|Xurkitree10]] ([[User talk:Xurkitree10|talk]]) 11:17, 2 January 2023 (UTC)
