This image shows dry ice evaporating in a cup of water. The dry ice sinks to the bottom of the cup, where it quickly evaporates and releases bubbles of CO2 fog. These bubbles then rise to the surface of the water where they pop and produce these interesting flows of the fog. Most of the fog slowly fills the cup and then spills over the edge, but there are also the occasional high energy bubble bursts that produce the spouts and rings that can be seen flying above the cup.

I’m always impressed by formation of rings in liquid or gas mediums. Carbon Dioxide diffusing into the air creates a wonderful semi-transparent vapor.
I like how you can see rings at different angles in this flow. It is very complex.
Really great use of contrast here, Matt. I also think the shutter speed used lead to the vapor looking continuous in some areas, which is interesting.
I love the contrast, it makes the vortex rings super easy to see and is also visually pleasing.
I love the rings that you can see coming out, the whole image looks super cool and spooky
This Image is really interesting, I like how clear the smoke is and the contrast with the black background.
I really love how bright you were able to make the vapor and how dark you made the background. This picture has really good contrast.
This is a great photo of vortex rings from dry ice. The black background really makes the fog pop as well.
I really like the contrast between the white and black. I also really appreciate the rings that you were able to capture!
I think it’s really interesting how a vapor ring formed from the reaction. I also like the black background in contract to the white smoke.
