people jar
Just like most everything else people find creepy for various reasons, some artists like putting people in jars. Experimentation, containment, study, incubation, medical reasons or just plain old sucking out their "life energy". Some artists just love putting people in jars and especially love comparing them to insects or pickled specimens.
Oh, call them pods, tanks, containment units or chambers all you like. These are people in jars.
