Luminous plasma gas can sterilize hands quickly

I've been a Drexel University student for 7 years (multiple degrees) and had no idea we had a "Drexel Plasma Institute". I guess that's what's inside the building across from 7-11.

The interesting part of this to me is an athlete's foot cure.

Lots of places you can put this for cheap foot treatment to whole teams of athletes.

I wonder about possible cancer side-effects of high energy systems like this.
