The document summarizes an experiment on instantly freezing liquid soda into soda ice. The experiment works because soda contains sugar, flavors, and carbon dioxide that lower the freezing point of the liquid. When the bottle is opened, carbon dioxide is released, raising the freezing point so that the soda freezes instantly at the temperature it was chilled to. Tapping on the bottle causes bubbles that allow ice crystals to form, proving freezing can occur without opening the bottle.
