Without electricity without magnetism without spring

Some water on his head began to shake

If the water in the cup can keep

Day and night foot

Wonderful wonderful wonderful

It can also do prediction

Less cloudy and rain water

Windy day fine to drink enough to

Anniversary most in need

Gifts from relatives and friends as the best

Ancient Chinese toys " water bird " similar to a perpetual state once marveled at the great scientist Albert Einstein. "Water bird"image of his last public appearance was in the last century30days on a foreign popular science books when, then disappeared. 这只神秘的“饮水鸟”发明于什么时候？ Not civil if there is spread? Do not know. Using some of the information at that time, we found some fragmentary memories about this toy. Hope interested readers can help us find or"resurrection"this mysterious bird, enable more people to share the wisdom of the ancients.

7 月份开始的大型 “ 中国古典物理玩具展 ” 已经进入了紧张的筹备阶段， Beijing toy Association Committee on educational toys main prefix = ST1 NS = "urn:schemas-microsoft-com:Office:SmartTags" renyujunxiong recommended by the teacher, they are eager to find out a lost called " drinking bird ” 的玩具，或者希望能有有心人把这种玩具 “ 复活 ” ，以便这个神奇的 “ Water birds " can see kids in the exhibition.

Vintage toy is perpetual motion?

Meet with the teacher, he excitedly told me the fabled toy. According to teacher introduced this old Chinese toy shaped like a bird, from the main glass. Its body is a glass tube, the upper end of the tube is a small ball, that bird's head, is a big ball at the lower end of the tube, which is the tail of the bird.

But erect while it will be bent until beaks dipped into the water,"drink"a mouthful, there will stand upright. In this way, it kept nodding to drink water, it is like a perpetual motion machine. Perpetual motion machine in scientific theory is impossible, so what is this all about then?

Einstein is a wonder to behold

That even the greatest scientist Albert Einstein for it as a surprise. Teacher Yu said, according to the well-known science writer, bielailiman, mediated by the former Soviet Union mentioned in the funny physics sequel, someone will put color, see the inner Mysteries of this"water birds"presented to Dr Albert Einstein, and said to him, Scientists say that perpetual motion is impossible, don't you now look at the perpetual motion machine.
