Large ice cube vs. small ice cubeI'm just wondering, when you put a large ice cube and a small ice cube in a glass, why the large ice cube float while the smaller one sinks?
I am sure there is some error in your observation, or you have not described your your observation correctly, with all the accompanying conditions when you observed ice cubes sinking.
Irrespective of their size ice cubes will always float. It is possible that with too many ice cubes in a glass some will be pushed below the surface of the ice, because weight of the ice above them is pressing them down. But the ice cubes will never sink to the bottom of the glass without anything pressing them down.
