How does water make smarties dissolve?

Water makes Smarties dissolve primarily due to its polar nature, which allows it to interact with the sugar and food coloring in the candy. When Smarties are exposed to water, the molecules of water surround the sugar molecules, breaking the bonds that hold them together. This process, known as solvation, causes the sugar to disperse into the water, leading to the dissolution of the Smarties. Additionally, the pigments used for coloring can also dissolve, contributing to the vibrant colors that can be seen in the water.
