Expand Your Mind

No one gave a single answer to yesterday's challenge, and I suspect that it's partly due to being bogged down in my Why The Hell Are You Here? question (which, if you haven't answered, please go do), and partly due to so many of my friends here being hyped over the new Star Wars flick (which I understand was very good). So, I'm reposting it today:

Picture a liter of milk and a liter of Kahlua. A cup of the Kahlua is poured into the milk and mixed thoroughly. Then, a cup of that mixture is poured back into the Kahlua. Is the amount of Kahlua now in the milk more, less, or equal to the amount of milk in the Kahlua? Explain.
