LED nose stud powered by breathing

Nose studs are cool right? How ’bout having an LED light on, hmm are you going to shove a battery up that nose? Some dude in Israel has got it all figured out, and they called it the Firefly. The Firefly LED nose stud is powered by electricity generated from your breathing airflow? (check out the tiny turbine above) Next time when you see a brilliantly bright star, it may well be somebody sneezing. — Sam Chan
