Talk:Hot chocolate effect

Response to speedy-delete tag
Hot chocolate effect is a scientifically documented experiment, unless you think that the American Journal of Physics is just bullshit. Please try to read the Crawford article, or get someone who understands physics to read it. — Preceding unsigned comment added by Makula (talk • contribs) 17:48, 25 March 2007 (UTC)

Removed speedy delete tag
I removed speedy delete tag since this does not meet any criteria for speedy deletion. This could go to AFD. I prefer to let it be expand by the author or other interested editors since it is documented by a reliable source and likely will survive an AFD at least as "no consensus to delete".

Seems contradictory
The statements in the article seem contradictory. Some say the frequency/pitch will increase then decrease after addition of a powder, others say they will decrease then increase. Which is it? 65.129.252.233 (talk) 15:58, 5 October 2014 (UTC) I'll rephrase the article to make more sense. Kumorifox (talk) 17:05, 5 October 2014 (UTC)
 * Every combination of stirring and tapping will give a decrease followed by an increase. So if you stir a powder into the water and then stop stirring and start tapping, you will hear a decrease and then an increase in pitch. But if you start stirring the same solution again, this time adding no powder, the process repeats, so you get another decrease followed by an increase. This process is not infinite though, eventually all the powder has dissolved or all the gas has escaped and there will be no further changes in pitch upon stirring.

"allassonic effect" ??
What's the source for this? "allassonic" is not a word in dictionaries: could it be one of these cases where Wikipedia vandalism got copied by many other sites around the Web? Equinox ◑ 11:07, 25 June 2022 (UTC)
 * Added in this edit. DMacks (talk) 06:09, 5 July 2022 (UTC)
 * That addition was in 2012. This YouTube video from 2007 includes the term, and a comment there posted "13 years ago" also mentions it (disproving a concern that the video or its description could have been updated after the WP-article addition). I can't find any other ref, so while it's not simple enwiki vandalism I also can't find anything beyond this kitchen-chemistry demo as an origin of it. DMacks (talk) 07:26, 5 July 2022 (UTC)


 * Indeed, I think we were trolled again by some nonsense like the "Bibhorr formula". Anyway, I removed it long ago, and nobody has re-added. Equinox ◑ 21:51, 25 July 2022 (UTC)
