SING making SALT disappear
-
I ran across a save by Xenarchus89 (id:2308417) that demonstrated an odd phenomenon. A two-part DMND enclosure, with saltwater in the top, and SING in the bottom. When SING is continuously added to the bottom section, the water and salt separate and the salt gradually vanishes.
In order to run a second, squeaky-clean experiment, I built another, with the same materials but not precisely the same dimennsions, and had the same result. I added an automatic SING-slinger so I could run it as long as I wanted hands-free. (id:2316955) It takes a few minutes, but eventually every trace of SALT is gone, leaving pure DSTW.
Xenarchus89 has given me permission to carry on with it, so I am publishing my save as well as posting here. We would like to know why and how this happens.
Please don't reply with "explanations" like leakage. This is a rigorous experiment, not a sloppy n00bsave. It is a real mystery, at least to those who have observed it.

SLTW has a 25% chance of turning to salt when boiled, otherwise it turns to WTRV, so repeatedly condensating and boiling it decreases the number of salt particles.
If the initial number of SLTW particles is the same as the final number of SALT+DSTW, there's nothing wrong with it.

I CARE. Yes, I can see that the recondensation plus the statistical crap "explains" it, and I can see that the salt is being converted to dstw (not very realistic, BTW!) -- but it is still interesting that it happens in a short time with SING. There is no visible re-dissolving of the salt except for a thin layer at the salt/dstw interface. But the particles move around, mixing very rapidly -- you can observe this by coloring the salt; colored particles of dstw appear all over. It is very different when other heat sources are used. There is gravity involved. I am trying to reproduce it in other ways, but it's hard to control the movement. It wants a rapidly reversing gravity field?
I really love how science lovers refuse to do it sometimes, and put down others for acting on their curiosity.

I remember an old FP save that use SPNG to extract water from SLTW,
then use SLTW to "contaminate" SALT into SLTW.
Eventually, you get an unlimited water source by pumping water out of SPNG.
TPT is just full of these laughable non-zero-sum reactions but I think there has to be more people supporting the change for the devs to consider correcting these behaviours(because the change might break old saves).
Of course, most players don't seems to care about small details, so convincing them is difficult. -
The rapid movement is a combination of the high temperature and low pressure. High temperature means the water constantly boils, so the liquids move as they swap places with the gas. The low pressure exaggerates this effect by stopping the steam rising to the top of the container- it holds everything at the bottom, which forces it to keep reacting.
For the sake of science, try covering the upper half of the save in the wall that blocks air but not particles. When I tried, one side boiled, and the other remained liquid.
In fact, the water boils because of the low pressure more than because of the high temperature. Manually lowering it without providing heat has the same effect -
TPT isn't meant to be realistic anyway. There's a lot of non realistic reactions in the game, too much to count from.
-
I continued with the experiments, and, yes, it's the low pressure. Putting a line of PUMP at the bottom of a closed container and setting the temp to around -63C (210.15K) does the same thing without any heat applied.
I should know better than to ask questions; I always have to find the answers myself anyway.
Case closed.
