This plug leaks!

There's a hole in the dang thing. I figured out how to plug it with one of them bubble things. Works great now and the bubble thing sings a sweet song.

Predrilled stopper

I used this stopper when constructing a secondary fermenter. I drilled a 1" hole in a 2 piece lid I found at Lowes that snaps on with a threaded center. The stopper fit the 1" hole perfectly. Produced an awesome batch of pineapple tart sour with good clarity thanks to the secondary fermenter.
