your just load my jar with goodies, add a fermentation weight, put one of these silicone lids on the rim, and fasten it in place with a ring. The jar then burps itself through tiny slits on the side of one of the lid's bunny ears that functions as airlocks. It's a very simple mechanism that requires very little maintenance.
