Cheap and easy aeration gadget

Sorry if this has already come up, didn't have time to read the entire thread. Has anyone with the appropriate tools taken a measurement of oxygen permeated into wort after doing this in PPM?

I have read most of the thread and it sounds like on the whole, this idea works. I have a few friends who are engineers and presented the idea to them. They all had the same general answer "more tiny holes = more turbulance=more aeration". If your syphon and venturi effect are strong enough, surface tension is negligible.

I tried doing this last week with just a 1/2" copper Tee and it worked just OK. I think I'll try switching to the smaller piece of tubing with holes and see if that works better. More turbulence and what not.
