Ozonizing Oils and Suitable Bubble tubes

Anyone have any recommendations as to what container to bubble the oil in? I'm using the tallest, skinniest glass I have, and the sunflower oil keeps foaming up and spilling into the bowl I put under it. I give the stuff like 4" to foam up, and its still to short...

I was thinking some sort of glass tube, possibly finding some of the glass plumbing tubes they use in labs...

Any idea's? Tweet
