Think about any flavored beverage that is not colorless (tea, soda, sports drink). Suppose you share the beverage with a friend by pouring it into two glasses. Most of us would expect that the two samples look exactly the same and taste exactly the same. Write a few thoughts about what is happening at the nanoscale (i.e., what is the chemical explanation) that could be the reason for the expectation that they look and taste the same.
