Hi all! I've been practicing my macro photography ... (show quote)
Thank you for posting this inspiring photo. It's been drab looking this winter, with little snow. Your photo makes me want to mount my macro lens on my camera with an extension tube or two. I think I might also bring an eyedropper full of water.
As others have mentioned extension tubes reduce the light making it to the sensor. There are many ways to compensate for this light lose, including a tripod and more time or a flash or two. I think you captured a drop of water in the process of freezing. Wonderful!
Edit:
I just reread your post and see that it a bubble! Did you use soap? How did you do that?!

Ya! It's a bubble:) I posted a link previously in this post to some bubble recipes. Most of them consist of varying amounts of water, dish soap and light corn syrup and/or glycerine. Mine is a mixture of all these. The glycerine helps the bubbles last quite some time, but too much of that and the syrup can render the bubble mixture useless for freezing.

I own two sets (12mm, 20mm, & 36mm) Kenko auto-extension tubes, with absolutely no problems. Secure fit (no slop & easy to de-mount) and no internal metal surfaces (reduces unwanted reflections). Velco also makes a decent set of auto-tubes. Read more here: FAQ: Extension Tubes vs Bellows vs Tele-Extenders vs Add-on "Close-Up" Diopter Lenses at http://www.uglyhedgehog.com/t-26496-1.htmlCan you tell me what brand yours are? Is that allowed on the forum?

I just picked up the Tamron 90mm f2.8 (A017)! Joy! Now to get out and shoot! Oddly, this lens doesn't display f2.8.... the largest aperture I can set it to is f3.... I don't understand.

Excellent purchase! You will only focus wide open (f/2.8) so do not worry, as lens will automatically close-down at instant of exposure. At Minimum Focusing Distance, your DoF will be miniscule, even at f/16. Do you plan to shoot available light, or with diffused speedlight illumination?I just picked up the Tamron 90mm (macro) lens.

To begin with, I'll be utilizing available light. I have a speedlight and can have that off camera even. There's so much to learn and am only part way through some of the helpful info at the macro forum:) I don't understand the Fstop from this macro though.....it's not like my other lenses so it's confusing me a little.

My speedlight is
Flashpoint Zoom Li-on R2 TTL (V860NII).
I haven't had any occasion to use it yet, but I will, I just know it! Lol

Interesting feature of this speedlight is that it does NOT use AA batteries, but uses a removable Li-Ion Polymer battery, and has its own power cord for recharging from a standard outlet. I cannot determine proper Guide Number for this unit, because manufacturer has rated it in a non-standard format. It looks like it will function quite nicely as an off-camera speedlight for diffused macro illumination. Camera + macro lens + speedlight means that you are 95% to a hand-held, field macro-photography set-up. Just a few 'companion components' to go: http://www.uglyhedgehog.com/t-32754-5.html#2585532My speedlight is Flashpoint Zoom Li-on R2 TTL (V860NII).

I would love to give this a try. I missed the earlier post with the bubble recipe can I ask for it again please?
