We realized at school that there are 3 typical states of subject: strong, liquid or gaseous. Solids act how they do mainly because their molecules usually retain their orientation and stay in precisely the same position with respect to each other. The molecules in liquids are just the other: They can adjust their orientation and shift everywhere from the liquid.
