Does dry ice float?

Let's assume you are talking about floating on water here... The density of dry ice is between 1.4 and 1.6 g/cm^3 which means that, in the strictest of terms it will not float in water, which has a density of ~1 g/cm^3. read more

The density of dry ice is between 1.4 and 1.6 g/cm^3 which means that, in the strictest of terms it will not float in water, which has a density of ~1 g/cm^3. However, pieces of dry ice which are small enough will float in water due to the buoyancy of the CO2 gas which is generated when dry ice comes in contact with water at ambient temperature. read more

The air exhaled into the bubble is less dense than the gases comprising the dry ice smoke, but slightly heavier than the air surrounding the bubble. So although the bubble doesn’t float in the air, it does float on the heavier dry ice smoke. Safety Information. NOTE: Whenever you use dry ice, always be aware of the rules for handling it safely. read more
