Obviously the tanks are optimized for whatever it is they do (emulating senselessness?) but is it possible to emulate that?
How much epsom salt would you need and would it be cost-effective and safe to go down the drain relative to going out to an actual tank?
Please tell me it isn’t completely impractical and it could be done :)
It’s not practical.
However, have a shower in the pitch dark sometime. It’s the most ridiculously soothing thing imaginable.
Put your shower gel and stuff where you can find it by feel, obvs.
