A disembodied rubber tongue juts from a brass contraption upon a wall that links it with motors, tubes, and metal. Artificial saliva running down its painstakingly rendered elastic taste buds, the organ wriggles this way and that—a mute reminder to the eye of the swanlike exertion lurking in the mouth. This tongue is the work of Swedish artist Tobias Bradford, titled “That Feeling/Immeasurable Thirst” (2021), and if it sounds in any way appealing, you’re likely the right audience for “Weird Sensation Feels Good: The World of A.S.M.R.” (through October 16), a new exhibition at London’s Design Museum.
