Inside New York's Last Sensory Deprivation Tank | The Awl:
Here's the thing to know about Sam Zeiger—the curly-haired, fifty-something hippie who owns the last sensory deprivation tank in New York: he's not going to murder you. At least he didn't murder me. Unless he did, and blogging forever is just one brand of newfangled, bespoke afterlife torments you can qualify for now (versus pushing a rock up a hill or getting your liver pecked out by birds).
Still, even if it's sort of embarrassing to cop to having made an appointment for an hour of isolation, you should still tell someone where you're going and where dude lives. The fear of getting murdered can be a distraction and when you're floating naked in some man's house, distractions are dead weight.
