Two New York University grad students have created prototype sweatshirts that change colors upon exposure to pollutionâ€”â€œanything from car exhaust to second-hand smoke,â€Â reported Abbie Fentress Swanson forÂ WNYC’s culture section. One shirt dons a set of lungs, the other a heart. â€œVeinsâ€ running through the organs turn blue when a censor in the fabric detects high carbon monoxide levels, notes Swanson.
The studentsâ€”Nien Lam and Sue Ngoâ€”designed the shirts for a project they call â€œWarning Signs,â€ part of their masterâ€™s coursework for NYU Tisch School of the Arts. “Air pollution is kind of one of these things that’s all around us,” Lam says in Swansonâ€™sÂ piece. “You don’t see it, but it exists, and it’s invisibleâ€”and we wanted to bring that to light.”
