No friction, in other words a vacuum.
It is not possible to create a perpetual motion machine using 4 watering cans or any other materials. Perpetual motion machines violate the laws of thermodynamics and cannot exist in reality.
Perpetual motion machines do not exist. If they did we would not be paying almost $3.00/gallon for gasoline, as a perpetual motion machine implies free energy. Newton's laws tell us that is not possible. For further explanation read up on Newton's laws of motion and thermodynamics
A perpetual motion machine would not work because it violates the laws of thermodynamics, specifically the first and second laws. These laws dictate that energy cannot be created or destroyed, only transferred or transformed, and that in any energy transfer or transformation, there will always be some energy lost as heat. Therefore, a perpetual motion machine cannot exist as it would require continuously producing energy without any losses.
Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power. Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.
A perpetual motion machine is impossible because it would violate the laws of thermodynamics, which state that energy cannot be created or destroyed, only transferred or converted. Any machine that claims to operate indefinitely without an external energy source would go against these fundamental laws of physics.

Perpetual Motion Machine.

An imaginary device, which like perpetual motion, does not exist.

It doesn't. You can make a differential amplifier with a single power supply.
Neither can exist

Not according to the second law of thermodynamics. It is possible to create near perpetual motion by cooling some liquids to near absolute zero where they lose viscosity and can be made to continue to circulate through some apparatus. It isn't technically perpetual motion though, because one still needs to spend energy to keep the liquids at such a low temperature. Near perpetual motion can also be observed by the Earth, which orbits the Sun, and has been doing so for billions of years and will continue to do so for billions more. It isn't quite perpetual either because, in addition to the several different processes from which the Earth loses energy internally, the interstellar medium creates a tiny amount of friction which is in turn converted into heat, and so the Earth's orbit would eventually decay if the Sun didn't engulf it first in a few billion years when it turns into a red giant. In the end though, there is no such thing as perpetual motion.
It can't. That's the simplest way to explain why no successful perpetual motion machine has ever been built. --------------------------------------------------------------- Another contributor persisted: well it's just a matter of time and life!

Perpetual motion is impossible because it violates the laws of thermodynamics, specifically the first and second laws. The first law states that energy cannot be created or destroyed, only transferred or transformed. The second law states that in any energy transfer or transformation, some energy is lost as unusable heat. This means that a perpetual motion machine, which would have to operate without any energy input or losses, cannot exist in reality.
