So, not a linear clock? More a logarithmic one?

Imagine this, you hear he wedding has no wine, so you get some from a friend and replace the water jugs with wine jugs, then get everyones attention and and place a glass out, dump in the mixture and wave your hands, a few moments later it changes, and you say check the barrels at the back, they are all now wine!

I can see someone demonstrating this to me 1,000 years ago and thinking, “Well this is quite clearly the Devil at work!”

More like loading screen than clock.

I'm assuming all used different ratios?

This is what I come to Imgur for.

"last but not least", but actually yes ""least", that one has the lowest concentration.

The guy with the necktie discomforts me. That is not appropriate clothing for a chemistry demonstration.

Hmmmm, looks tasty.

Probably tastes better than any grape drink.

So, in short. There's 2 chemical reactions going on in each glass. 1. Slow reaction that produces the iodine (in dark purple form) 2. Fast reaction that turns produced into separate iodide ions. 2 'breaks down' the iodine faster than it is produced. At some point, the stuff fueling reaction 2 runs out, causing it to do a see-saw flip to the other side.

Why the delay, though? Amount of chemicals involved? They all seem to have poured at the same time.

The dilution factor determines the rate.

Different concentrations in the different cups!

Wouldn't be a very good clock if you yourself had to time it all out.

concentration ratios and pour speed.

Different starting ratios

It could be carried by an African ratio!

https://en.wikipedia.org/wiki/Iodine_clock_reaction - basically, two reactions are running while it's clear, with a slow "producing" reaction feeding a fast "consuming" reaction. Once the "consuming" reaction runs out of secondary ingredients, it can't consume any more, and products from the "producing" reaction start to build up, which are what you see as the dark color. Adjusting the first reaction speed (or the secondary ingredient amount) "tunes" the clock.

Nice description.

This is great! I’ve NEVER heard this sort of science talked about as a producer/consumer kind of thing. The ONI player in me had a nerdgasm.

It’s basically like a supply and command situation… https://media2.giphy.com/media/v1.Y2lkPTY1YjkxZmJlMmdmZGcyZGsxbHc2NnI4dzhraGJ1dzFoc3JqMnVtZHNrbzdzaDk5eSZlcD12MV9naWZzX3NlYXJjaCZjdD1n/26uf4ztgExZ3VEzUQ/200w.mp4

Oxygen Not Included??? That game is awesome! I always restart to make things more "efficient" and never make any progress towards beating the game :)

Hello fellow clean slate’r. I do this in sooo many games. I, for one, DO let perfect be the enemy of progress.

I always build my entire colony around a stupid goal like stockpiling a vast reservoir of superchilled liquid oxygen or something. It's fun though.
