Actually, an ice cube does. See, ice cubes are made with trays. Have you ever looked at an ice cube tray? They are actually cubes! Well, squares with a top exposed. There are different sort of ice trays, but the water will take the shape of whatever its in when it freezes. And liquid water will lose whatever shape it has once you take it out of its container.
Ice has a rigid crystalline structure that does not allow for movement. However, liquid water molecules slip and slide past each other with ease. The crystalline structure of ice is also the reason why dihydrogen monoxide expands as it freezes. This feature is also responsible for a certain type of erosion where water seeps into tiny cracks in rocks and breaks them apart when the winter comes.
