A Wet Finger in the Air, a single-channel video, assembles appropriated footage of bilingual weather reports from 1980’s through 1997-era Hong Kong TVB and Pearl broadcasting stations into a hypnotic, randomized loop that repeats every hour. While these reels may invoke a kind of nostalgia, Sia's interest centers more on locating atmospheric and weather changes as a metaphor for the similarly unpredictable and slippery turns of history. The artist metaphorically raises a wet finger in the air to judge the invisible direction of the times.
