Dry ice (solid carbon dioxide) is a classic example. As it warms up, it skips the liquid stage and turns straight into carbon dioxide gas. When placed in warm water, the cold gas condenses moisture in the air into a thick, ghostly fog that flows low across the surface.<\/span><\/p><p><span style=\"font-weight: 400;\">This is a perfect classroom demonstration of states of matter and phase change, turning a holiday trick into real science learning.
