WATER CYCLING, a cycling device that pumps water from underground and circulates the pond water. You can even connect it to a mobile device. Once you start paddling, the volume of water being cycled shows in real time. Your personal cycling score can be saved and accumulated. You can even compete to be the strongest cyclist that helps water to flow most.
WATER CYCLING not only helped to create a better environment for plants and animals,but also made the city healthier.
