Bubble rings[edit]

Thanks again for pointing out the importance of the spin direction. You mentioned also that you are the owner at bubblerings.com. Since that is a commercial site, you have a potential for conflict of interest issues, particularly around any articles to do with bubble rings. To avoid any difficulties please carefully read the guideline: Wikipedia:Conflict of interest, taking particular note of the section on How to avoid COI edits. It also would be good if you declare your ownership of your site on your user page. Anyway, welcome again, and happy editing. --Epipelagic (talk) 23:55, 28 December 2010 (UTC)[reply]

Thanks for the pointers. I have been reading up on how Wikipedia works in general, and reading all of the COI stuff too.

I'm not sure I made myself clear on the spin issue though. I'm not sure I know the right way to say it, so I will explain what I think I know to you, and see if you find a nice short way to say it.

(This discussion seems like a good way for me to learn a lot about how things are done on Wikipedia, by the way. But if you would rather I leave well enough alone just let me know, I am fine with that.)

The issue is what direction the ring is spinning in relation to the direction the ring is traveling through the water. For instance, most bubble rings created by humans travel straight up towards the surface of the water. In these cases, a bubble ring spins in the opposite way as the arrow shown in DaveBurke's drawing here:

The example of a bracelet rolling on or off an arm is a good one because it explains how the spin happens for people that don't understand what the word poloidally means. (They might think it means that the rings spin the way a steering wheel spins.) It is a bad example because the spin is in the wrong direction, whether the bracelet is going on or off the arm.

Maybe I can find or create a better drawing. I think we need a drawing like DaveBurke's, but with the spin arrow in the opposite direction, and another arrow that points straight up that is labeled "overall direction of bubble ring travel" or something like that.
