Plasma is ionized gas, we can agree on that, so how about SPRK separate the flow of plasma, like in real life?

10 px near plasma, sprk randomly separates plasma into 2 new elements

PPLS - Positively charged plasma, gets attracted to SPRK, a bit redder than regular plasma

NPLS - Negatively charged plasma, gets repelled by SPRK, a bit bluer than regular plasma

This could be useful for randomizers or heaters.

Nble already causes havoc with plsm when sparked, so that wouldn't change anything. In enclosed containers it also won't do anything, you could simply have PPLS and NPLS have a different tmp to decay into nble, PLSM that decays into water could also turn back into hygn and oxyg. And again you could also have this ionization as an optional feature in the settings.
