In a Little Five Points suite, FLO2S offers Atlanta’s only two commercial sensory deprivation tanks: Each holds body-temperature water, less than a foot deep, and 1,200 pounds of Epsom salts, dissolved to create ten times the buoyancy of the Dead Sea. Here, by yourself, you can settle into total darkness, total silence, and (best of all) weightlessness. You may experience spine decompression, a meditative state, even visions. Our tester left feeling “more relaxed than I have in years.”
