I've noticed something with my FIZZ-X rod that I can't find any information
about online. I hope my explanation makes sense.

Let the fins hang down before inserting the rod. They form an upside-down
V. Now flip each rod to the other side. You get what looks like the exact
same configuration. I can't see any difference between the two.

I have noticed that the effect on the wine is definately not the same. In
one configuration I can let the drill go for 30 seconds before I notice a
lot of surface movement. In the other configuration I get a defined vortex
in about 5 seconds. I've done back-to-back tests enough times now to be
sure of this.

I get a lot more released trapped gas from the 5 second vortex configuration
than a minute in the other configuration . That seems good to my neophyte
mind. On the other hand, could the vortex be causing increased oxydation?

Have you seen anything like this? Whether you have or haven't, would you be
happiest with the vortex or non-vortex configuration?
