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 :)
Float-tanks are this:
Imagine a bigger-than-normal bathtub, so you can sprawl-out ( arms & lega akimbo ) without hitting the sides…
the water-density is upped with brine, instead of plain water ( the float-tanks place I used to go to used sacks of “bitter salts” & the texture of the brine was damn-near oily, and DO NOT EVER shave shortly before going into a brine-soak, or you’re going to discover what stinging really means )
also it is brought up to a person’s body-temperature, or close to it.
When there’s no temperature-difference, & you’re floating sooo high that drowning is much less likely ( the Dead Sea is probably the prototype for all float-tanks, btw ), & you aren’t bumping into the walls, then you’re in blissful sensory-deprivation ( total dark, too, obviously, probably use a timer, limit it to 2h max ), & meditation can be awesome in these conditions.

Are the tanks sound proofed too?
More sound damped in quiet buildings. You can hear someone noisy in the room outside the tank, but normal sounds are blocked. So the building acts as sound damping, with more in the tank. At that point, all I could hear was my tinnitus.
