One piece S-shaped airlock that features a smaller chamber so you can closely observe the CO2 rising and with that, the rate of fermentation. Fill the airlock with water and insert into a drilled stopper to vent gases during fermentation. Also handy when you are cooling a beer as there is less of a chance of getting water sucked back into the fermenter. Innovative S design prevents backflow.
