airlock

This is an airlock, as used in winemaking. As the yeastie beasties in the wine-to-be transmute sugar into ethanol with their metabolic magic, they excrete carbon dioxide, increasing the air pressure inside the sealed chamber. The carbon dioxide pushes against the water in the airlock until it bubbles through. The water barrier prevents contamination from seeping in, and the green dye provides a handy-dandy method for ensuring that fermentation is actually proceeding.
