Scientific Description
Dry ice is the solid form of carbon dioxide which is the gas under room temperature. The dry ice will sublimate (the physic process that solid turns into gas directly) into carbon dioxide under the room temperature. The sublimating process makes the surrounding environment super cold and causes water vapor in the air to condense. That is where the fog comes from. The boat moves because of the newton’s third law - every action has an equal and opposite reaction. When the dry ice gives off the gas it makes the boat sail in the opposite direction. So, it is the carbon dioxide gas that pushes the boat forward.
Extensions
