Just bought a book that claims to be Home Brew Bible
(if interested book is here - http://www.amazon.co.uk/How-Brew-Everyt ... 181&sr=1-4)
...and in the 'equipment needed for first brew' chapter it lists an Airlock or Bubbler as they are known.
This airlock appears to be sticking out of the top of the FV.
I am on my 4th brew now and have never used one of these....am I missing something important here

Should I buy FV's with holes to attach an airlock or do you have to buy them specially?
Cheers
Jase
