Interesting take in the theme author, well done.

brilliant

Excellent shot! And we have yet to see clarification as to whether or not the overflowing object must include liquid, so until we here otherwise I consider this to be on theme. GL!

Hrmmmmm... If this was done with dry ice, then it isn't really "smoke" - it just looks like it. It would basically be frozen condensation from the air (I think). I guess that would mean it was from moisture, which is water. Soooooo, technically, I guess it would be water overflowing from the glass. ( IF it is dry ice)

Technically its in a gas state not a liquid state. Dry ice needs to be colder than -69 F to stay in a solid state other wise it turns to a gas. I doubt its below -60 in the picture. Probably why its called DRY ice.

The second sentence of this contest reads as

"Create an artistic shot of anything overflowing." The contest guidelines DO NOT specify whatever is over flowing has to be a liquid. Sure, it's insinuated because liquids are typical of overflow but anything is STILL "anything".

Entry is ontheme, "Create an artistic shot of anything overflowing." Anything is the key word here and this line in the description tell you what the goal of the contest is.

very nice shot
