I don't derive any pleasure from reinventing the wheel, but I do take great pleasure in taking advantage of what others have learned and passed along to me. In this case, I'm referring to a September 2013 article in Popular Photography magazine.

Setup (To be ignored unless you are really interested in the details.)
The setup explained in that article is very similar to a setup I have used often in my makeshift studio that produces a black background and defines the shape of clear subjects with bright lines.
The parts of my setup that are the same as in the article are the glass tabletop and the narrow chamber to hold the soap and bubbles (in my case, a modern flower vase).
The rest of my setup is different from the setup explained in the article: Rather than using a huge piece of translucent Plexiglass placed behind a black background, I use a circular, fabric diffuser that isn't nearly as large. Also, rather than using four strobes fitted with reflectors positioned around the black background, I use one speed light positioned behind it. I also use no power packs, as my lighting equipment works fine using only standard electrical outlets.
My setup also includes a medium continuous-light lamp positioned to the right or above the scene, depending on the photo, not included in the article's setup. Without that lamp, I was unable to get enough of the bright, colorful tones displayed on the sides of the bubbles.
There is one other teensy weensy difference between my setup and the setup explained in the article: mine costs about $300, about $9000 less than the setup explained in the article. That doesn't include the difference in cost between my inexpensive circular diffuser and the outrageously expensive sheet of Plexiglass used in the article's setup.
I tried using the article's suggested mixture of soapy liquid used by children to blow bubbles, glycerine and water but that didn't work for me. I settled on a mixture of the children's liquid and Windex, mostly because the Windex adds the blue tones to the liquid shown at the base of my photos.
