Properties of Liquids

Q. When sugar is added to water the level of water does not increase because the sugar molecules occupy the space in between the molecules of water. But if we add lots and lots of sugar in water, shouldn't the sugar molecules compress the water molecules and form a solid? But they don't? Why?
