I went to college (surprise) with guys who would eat pizza crust off the floor. They either had really good immune systems or spent quite a bit of time on the toilet. I on the other hand, am a bit of a germarphobe, I don’t even like sharing drinks/straws with family. Sorry Mom. So when I saw this UV light that fits in your pocket and runs on 4 AAA batteries my curiosity was piqued. A simple wave of the magic light (for 10 seconds) kills 99.9% of the germs on most surfaces. I like. It is available for $18… or if you want to support a bankrupt company you can buy it for $80 at Sharper image.
