PHBananas glow blue under UV lights
Bananas may be famously yellow, but according to a study published in the Journal of the German Chemical Society, the usually sunny-toned fruit actually glows an "intense" blue color when put under black light (or UV lights).
Scientists at the University of Innsbruck in Austria and Columbia University in the U.S. found that the degradation of chlorophyll that happens in the fruit while it ripens is the cause of the funky blue glow.
