Smokin' glasses

Just some fun with smoke and glassware. I've never tried these before, but it was pretty cool, c&c welcomed!

They look like they could be pretty cool, but there is so much white! It's hard for me to make out what is actually in the photos.

I agree, its a great idea, but perhaps you could use a black background with a gel'd light facing the smoke, but out of the frame so that the camera doesn't get the light in the picture (or a lens flare for that matter) ? Other than that, its a great idea
