What is a waterlock?

The waterlock ensures that carbon dioxide can escape, but that no oxygen, fungi or fruit flies can get to your fermenting vegetables or whatever type of fermentation you use it for. The rubber grommet ensures that the waterlock fits perfectly in your lid and that no gas can escape around the edges.
