Soda doesn't directly change the way an ice cube forms. The process of freezing water into ice is the same regardless of whether it's plain water or soda.

However, the *presence* of soda can influence the appearance and behavior of the ice cube:

* Bubbles: Soda contains dissolved carbon dioxide gas. As the soda freezes, the gas bubbles can get trapped within the ice, creating a bubbly, less dense ice cube.

* Color: Some sodas have added coloring. This coloring might be visible in the ice cube, giving it a faint color.

* Sweetness: The sugar in soda can affect the freezing point, making the soda freeze slightly slower than plain water. This can lead to a larger ice cube with a more porous structure.

It's important to remember that these are minor effects. The fundamental process of water freezing remains the same, and the ice cube will still be primarily made of frozen water.
