What happens if you shake 3 sugar cubes in a jar?

If you shake three sugar cubes in a jar, they will collide with each other and the walls of the jar, breaking apart into smaller granules due to the force of the impact. This process increases the surface area of the sugar, making it dissolve more quickly if added to a liquid. Additionally, you may hear a rattling sound as the cubes tumble around. Overall, shaking the cubes can effectively create a finer sugar texture.
