Dry ice is solid carbon dioxide that stays at a freezing temperature of negative seventy eight degrees Celsius. Instead of melting into a liquid, it turns directly into a gas through a process called sublimation. When you place dry ice inside a container of warm water, it rapidly creates a thick white fog.
By stretching a cloth soaked in liquid soap across the top of the bowl, you trap the expanding gas inside a single giant bubble. The warm water accelerates the sublimation rate, causing the soapy film to stretch outward into a perfect dome full of heavy white smoke.
When the delicate soap membrane finally pops, the trapped carbon dioxide gas pours out instantly and sinks toward the table. Because cold carbon dioxide gas is much denser than the surrounding air, it creates a stunning fog waterfall effect that spills over the edges.
