Will it fit ?

Hi guys ,
Will these bungs http://www.the-home-brew-shop.co.uk/acatalog/Rubber_Bung_for_Demijohn_Bored_WITH_HOLE_.html

work in tesco 5L water bottle.

Saving money.
But I'm thinking they may be too small

Not sure but if you have the top you can drill a hole (9mm if I remember correct) and fit an airlock, if you want to do a "proper" job you can buy grommets.

Hi.
I never use bubblers in 5L PETs. Just a new small freezer bag
over the top secured with an elastic band like the ones
posties drop everywhere. Gas can get out, bugs cant get in.
Never had a spoiled brew yet.

If you want a laugh buy a pack of Durex and put a pin hole in the end and put one over the neck.
