Side Note:
It seems that there is a lot of debate surrounding using mason jars to ferment (read here).  The issue, as far as I can tell, is whether a mason jar creates an airtight seal to allow proper fermentation to occur. Here is my take on this whole thing.

During the fermentation, CO2 is released, filling the non-liquid part of the jar and putting pressure on the water in the airlock. Assuming the water in the airlock moves and occasionally bubbles, it means that there is a positive pressure situation inside the jar which means that air (CO2) is being released out of the jar while nothing is getting in. If the lid wasn’t sealed well enough, the airlock would never bubble because the built up pressure would be released through the lid.
