Here’s something for everyone that’s been told that the bubbles moving downward in Guiness Stout are an optical illusion.

And I had always just thought it was divine intervention that brought the bubbles down! Now I have absolutely NO proof that there is a god! 😉 * * * “Teaching without words and work without doing are understood by very few.” -Tao Te Ching ---

I never heard that this was supposed to be an optical illusion, so i don’t see what the mystery is. Also, wouldn’t it be easier and more definitive to use a camera to take a motion picture, and view it in slow motion? …nevermind. I was poking arund the [fluent website](http://www.fluent.com/index.htm). This was publicity for fuid dynamics software. Possibly they did take movies to be sure the software worked correctly, and just don’t mention it. * * * _It is too clear, and so it is hard to see._ ---

Padeye, don’t post an OP like that the day of the Phoenix gathering unless you’re prepared to move on from Coffee Plantation after a while (assuming special also agrees). You’ve put me in the mood for a black-and-tan (only 1/2 a Guiness, I know, but still…). ---

Strainger, nothing says this has to be the only Phoenix gathering. We can get together for stout another time if not after the coffee bar tonight. I’ll be easy to spot. Look for a big fat bearded guy in a green polo shirt wielding a video camera. I think I can dispense with the white carnation and secret password. * * * Come let us go, I’ve a cask of amontillado. ---

True, Padeye. I guess I’m just not used to having gatherings with SDMBers that I actually live _close_ to. See ya there! ---
