What is an air lock? I don't speak English, pardon.

 Hi when you are making home brew you need to allow the carbon dioxide gas produced by the yeast to escape but you also need to stop harmful airborne bacteria and mould spores from getting to the brew. An airlock allows the carbon dioxide to bubble out through the water but doesn't allow the air into the brew. Hope this helps feel free to ask for more clarification.
