Dry ice fog is a thick, dense, low-lying fog created exactly the way fog in nature is. created, by condensing water vapor out of the atmosphere. We use dry ice (the. solid form of carbon dioxide) to condense the water vapor out of the air. Dry ice. fog contains no chemicals, glycols, or oils, and is truly a water based fog.
Dry ice is frozen, compressed carbon dioxide gas and when you add it to warm water, it combines with the water to create the fog (carbon dioxide and water vapor) that you see bubbling out of your cylinder. Adding soap to burping, bubbling, smoking water creates a whole new effect.ry ice is frozen, compressed carbon dioxide gas and when you add it to warm water, it combines with the water to create the fog (carbon dioxide and water vapor) that you see bubbling out of your cylinder.
