Isn't it sinking because CO2 is denser than air?

@gdj, yes. There are three things going on. The "smoke" consists of droplets of condensed water vapor. Water droplets and CO2 are both denser than air, and are especially dense because they are cold. In time, the water vapor will reevaporate and CO2 will blend with the rest of the air as temperature equilibrates. Caution: CO2 displaces oxygen, so it's probably not a good idea to lie on the floor in a room like this for long.
