Lately I've been taking some photographs for a friend's research project on Air Quality Balloons. It turns out, if you hook a VOC sensor to a computer chip and an LED, you can make balloons change from green to yellow to red as the surrounding air quality gets worse. Our research shows that drunk people in Shadyside on a Friday night really like giant balloons that change colors ;)
This project is part of a growing movement, called Citizen Science where individuals, often non-scientists, take part in research-like activities. In this case, it's sort of simple data collection and visualization. Is the air around you clean?
P.S. As an amateur photographer, there is nothing more difficult than photographing moving balloons outside, in the dark. I made a valiant attempt here.
