Properties
of Water There are several properties that make water important to
life on our planet, as well as important to operating a fountain.
Gravity
Understanding the force of gravity is important in understanding how
fountains work.
Pressure
Fountains use pressure to push or pull water against the pull of
gravity.
Hero's Fountain
This example applies the principles of both gravity and pressure.
Human
Heart Pumps show up in other places besides fountains. One
familiar pump is the human heart.
Automobile
Fuel Pump Another common pump is an automobile fuel pump, which
allows gasoline to pass from the tank to the carburetor.
