The scorpion is a water extraction tool invented by the ancient working people discovered in China. The ingenious use of the principle of gravity has made today's people feel amazed, and feel the scientific wisdom of our Chinese ancestors!
When the sputum is waterless, the center of gravity is below, the mouth is up, and the water can be filled; when the water is filled, the center of gravity moves up, and when the center of gravity exceeds the balance line, the cock turns over and the opening is downward, so that the water flows out.
