This airlock or fermentation lock is filled partially with liquid (water/vodka, whatever) and it sticks in the
top of a drilled stopper and into the top of your fermenter. It allows the fermentation gasses to escape
without allowing anything to float down into your fermenter. You should have several airlocks and a few
extra (trust me on that one).
