The Belousov-Zhabotinsky Reaction
Added 2018-07-14 15:23:22 +0000 UTCHey guys, first video in a while! I hope you like it, let me know if you see any mistakes. It took me forever to finish this project!
Ill add your names and everything in the final version of the video, which will be posted tomorrow.

2018-07-16 14:36:36 +0000 UTCThose bubbles in the "bad" runs were fucking awesome. The rapid sort of chaotic wave patterns were great to watch. Same with the huge scale runs at the end.
2018-07-16 06:56:28 +0000 UTCAwesome! Science is art!

2018-07-16 05:14:14 +0000 UTCDid you try to prevent nucleation of the bubbles? (e.g. by using new and very clean glassware)

2018-07-16 05:11:00 +0000 UTCI really liked the contrast with the bubbles though, that was very nice :D
2018-07-15 20:52:22 +0000 UTCCan we have 10 hours of these reactions in HD to put as background for my other exmeriments? :)

2018-07-15 19:32:46 +0000 UTCCongrats! I have dreamt of performing this reaction, but had too much problems with gathering and keeping the ingredients.
2018-07-15 12:32:55 +0000 UTCVery nice video. Thanks. The formula for malonic acid is better written as CH2(COOH)2, a methylene group with a carboxylic acid group on each side.

2018-07-15 08:31:56 +0000 UTCI have only one thing to say:.. Nile this experiment made me proud, that I'm supporting you! A real nice video!

2018-07-14 23:37:04 +0000 UTCVery cool and well explained too I think.

2018-07-14 20:47:18 +0000 UTC5:40 "malonic" acid not maloni.

2018-07-14 19:03:40 +0000 UTCBeautiful video! I hope you'll cover the other variations, im particularly interested in the cerium one. I love the videos where you just cover one reaction and explain the mechanism in detail i hope you'll make more in the future!
2018-07-14 18:16:31 +0000 UTCwow! Especially because I have produced the exact same patterns with a neural network years ago. Even the spirals, and the "chaotic" patterns. The neural network was quite simple, and I can get all these patterns by varying only one parameter. I think the the visible dynamics can be reduced to a few simple non-linear partial diff. equations.

2018-07-14 17:42:49 +0000 UTCI love the Belousov-Zhabotinsky reaction, similar patterns turn up on watermelons infected by the Watermelon mosaic virus for some reason. I recently saw it occur on some guy's fence as well <a href="https://www.thisiscolossal.com/tags/fences/" rel="nofollow noopener" target="_blank">https://www.thisiscolossal.com/tags/fences/</a>

2018-07-14 17:37:17 +0000 UTCWay cool! I love these oscillating reactions. From your readings, do bubble-free variants last for more cycles due to not having the irreversible loss of CO and CO2? One issue: @5:34 Beaker B says maloni acid instead of malonic acid.
2018-07-14 16:23:22 +0000 UTCThe blue flashes you mention are indeed weird, but I think they look super awesome and make the entire reaction even more beautiful, because they seem so random and different in appearance. They are the same color, but make a good contrast from a shape point of view.
