I have come to find that if you fill the bottle containing the the yeast 
mixture too full and shake it occasionally, some of the mixture is bound 
to make its way slowly down to the airstone and collect.  I noticed this 
same occurrence repeatedly till I started filling just barely over half 
way.

At any rate, the goo never seemed to affect the chemistry of the water, 
but I was paranoid so I filled the 2-liters less.
