Two graduate students from NYU recently created an interactive new project called “Warning Signs.” The two students invented t-shirts that change color when exposed to high carbon monoxide levels. The shirt designs feature a heart or a set of lungs. This isn’t any ordinary type of clothing because when the fabric is exposed to pollution (ranging from cigarette smoke to car exhaust), blue veins appear on the organ image!

Co-creator Nien Lam explains, "When people would step out to have a cigarette, they would see our project, and then feel guilty going out to have that cigarette realizing, 'Oh, this is actually what I'm doing to myself.'” The American Lung Association reports that 6 in 10 Americans live in places with dangerous levels of air pollution. Cigarette smoking leads to over 440,000 deaths per year in the U.S. alone. 600 million trees are destroyed per year to make dry tobacco.

The NYU duo are now thinking about creating clothing with alcohol sensors. They may have the liver change color when the wearer has consumed too much!
