Treebeard's Stumper

My Cup Runneth Over?

We'll start the year in science studying water, so here's a water stumper. Take a glass of your favorite cold beverage, add a few ice cubes, and then fill it completely to the brim. The ice cubes of course will float above the top. Now set the glass in a warm place and wait. What will happen to the water-level as the ice melts? This is a fine experiment for an (almost) summer day, but make a guess or hypothesis first, and think about your reasons before and after. Would it make a difference if the ice cubes were hollow?
