Spin the wheel is a wheel-shape device that is partially immersed into water to take effect on water or from water. For example, water wheel of a mill makes use of water flow that propels the water wheel to drive the grinder to grind crops.
In a similar way, water wheel can be used to drive a generator to generate electricity. On the other hand, there is an inverse application of water wheel: For example, in paddle boats power is supplied to drive the water wheel for propulsion.
There are also water wheels that are used in agriculture as water-lifting devices that deliver water from a lower ground to a higher ground.
