Black Ink Tutorial Shows Proper Hand Washing Technique

Do you forget about your thumbs, too?

We’re told to wash our hands for at least 20 seconds. But that doesn’t mean just rubbing your palms together while you sing “Happy Birthday” or “Stayin’ Alive”.

First of all, why soap? Soap molecules are pretty special. They have a ‘head’ that ‘loves water’ and a ‘tail’ that ‘hates water’.
