Use your mouse to drag the man around the screen. Take him up the hill to water the flowers. As he goes up and down the hill, what happens to the rate at which the water flows from his hose? Why can't he water the flowers at the top of the hill?
Does this give you any ideas about why small towns use water towers, but big cities rely on other methods of getting water to flow through their pipes?
