无源水

       原理：无源水龙头是一个普通水龙头，没有进水管，但水却不停地往下流。其实在水池下安装着水泵，与水泵相连着透明管，透明管通过上端的支撑杆与仿真水龙头相连，并将透明管的顶端罩在仿真水龙头中；水泵将水泵入透明管，并从透明管的另一端流出，由于透明管内外都是水，好似从仿真水龙头中流出一样，从透明管顶端流出的水又沿透明管的外壁落入水池中，可循环往复使用，这样就给游客一种假象：水在不停的流，却看不到水是从哪里来的，如此简单的结构，却给人产生新奇感的特点。

　   操作：观众观看这种现象，不用操作。    

No source water

      Principle: No source water faucet is a common faucet, it has no pipe pulling water in but the water runs down ceaselessly. In fact, the pump, which is installed under the basin, connects with the transparent pipe, through the knighthead above, the transparent pipe connects with an emulational faucet and the top of the transparent pipe is hided. The pump pulls water into the transparent pipe and pushes it runs out of the other end of the pipe. Because there are full of water both outside and inside the transparent pipe, so it seems as if the water is running out of the emulational faucet. The water that runs out of the top of the transparent pipe drops along the pipe into the basin, which is repeated over and over. Thus the visitors will take it for granted that the water runs ceaselessly, but where it is from remains as a riddle. With such a simple design, the exhibit produces a novelty.

　  Operation: the visitors observe without interference.
