The Smoking Bowl!
It's a bowl with white "clouds" coming out from it. Cool huh? It seems as if something's gonna pop out of it. Now you have a reason not to eat that horrendous bowl of soup.
Here comes the interesting part - The Question!
What caused those smoke? No...it's not Steph who photoshoped all those smoke there.
I don't have any prizes for the correct answer, but the first to answer will get the satisfaction of being the first to answer :D
Update 29th May 2008:
Bob was the first to guessed the correct answer. The answer is dry ice was placed in the bowl of water.
