Science is magical. In this magical world, there is a kind of bottle called Klein bottle, which does not exist in the real thing, but is conceived by scientists according to the four-dimensional space. The mathematician who invented this bottle is called Klein. The uniqueness of this bottle is that no matter how you put it, the water here will flow out, and the bottle will never be full. So far, scientists have not made this kind of bottle.

At present, the Klein bottle we can see is drawn by computer, and its existence should be in four-dimensional space, but our current technology can only reach three-dimensional space, so there is no way at present, and it is impossible to realize four-dimensional space now. Scientists say it's because the current technology can't reach the fourth dimension. But with the progress of science and technology, it may be possible to realize four-dimensional space in the future.

Some scientists say that Klein bottle is like a black hole, the bottom of which extends all the time and cannot be filled with water. However, some scientists have carried out simulation experiments through computers. They put an animated ant in a Klein bottle, but they didn't expect it to come out. So scientists put forward that Klein bottle is an expansion space without direction.

At present, the exploration of Klein bottle can only stay in computer technology. Scientists actually thought about making such a bottle through the existing technology, but they tried countless experiments and failed in the end. Fortunately, there is a computer, and the simulation is realized through the computer, which is an improvement.

Science is magical. It is precisely because of the continuous research and exploration of scientists that our society is so rich and colorful. Presumably, the Klein bottle can be made to fit the real thing, and the society will undergo greater changes.

As for the future, whether you can make such a bottle depends on the future development. Do you think it is possible to make a bottle?

Well, typing so many words is really not easy. I just hope all the readers will pass by, and I will be very happy after reading it. I wish you health, happiness and success!
