Spaghetti is denser than water and, therefore, sinks when placed in water. When spaghetti is placed in a solution of baking soda and vinegar, the spaghetti rises to the surface due to the carbon dioxide gas that adheres to it. When the spaghetti reaches the surface, the gas is released, and the spaghetti sinks again.
