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 :)
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.
