A Moment of Science
Oddly enough, a solution of 70% alcohol, that is, rubbing alcohol, is a more effective antiseptic than 100% alcohol. Another case of where more is not better.
Studies have shown that ethanol–which is a kind of alcohol–causes skin cells to put out the same neurochemical signals they put out when heat is around. The result is that it doesn’t take as much actual heat for the VR1′s to turn on.
