I’ll take me the Fringe sensory deprivation tank. Sure it takes up a lot of space, but at least you’re floating in a dark soundless void. Combined with Walter’s drug cocktails it’s either going to be the most peaceful deep sleep you’ve ever had or the most horrific dream hellscape you couldn’t even imagine.
At Rocketdyne there was a valve tech who built a couple of “nests” for himself. He’d use them at any time during the day, breaktime or not; mostly not… based on reports. His nesting materials: Cleanroom coats, and lint-free wipes and large surface cloth. His pillows in both “nests” were large heavy-duty bags (used for maintaining cleanliness of built engine valves) stuffed with cleanroom materials (see above). So, those were his pillows. Oh. You want to hear the rest? Okay. His hidey-holes: 1) An in-wall, ceiling-to-floor, shallow storage closet in the hallway leading to the valve room’s main airlock. We witnessed him sneaking into it one day for a snooze. Later, we found the closet floor heaped with lots more of the soft stuff; 2) an enclosed utility space (located inside the cleanroom) used by maintenance-only to access shutoff and relief valves for the cleanroom’s LN2 and high pressure He/GN2. Less than 3’ wide and ~18’ deep, it made an invitingly snug place for all the soft stuff. Rocketdyne in Canoga Park was really bustling with work at that time, so I never noticed when he simply just disappeared from the scene. Fired? Retired? We’ll never know.
