If you are feeling at all uneasy about spending two hours floating in water in total sensory deprivation, Crash, the shaggy-haired, flip-flop–wearing owner of Float Lab, will make you feel at ease. Each of his two womblike chambers is filled with body-temperature saltwater and encased in dark, soundproof walls. With nothing to distract, you are free to explore your mind completely unencumbered. During the big isolation-tank craze a few decades ago, it was said that some famed writers came up with their best ideas inside the tanks, and that the mind invented vivid colors and patterns. Stand-up comedian Joe Rogan is a fan and regularly touts Float Lab on his podcast. The popularity and constant waiting lists have prompted Crash's expansion plans, with a new 10-chamber facility on Wilshire in the works. 801 Ocean Front Walk, #5, Venice.
