The method of Mobius tape is to take a long piece of white paper, paint one side black, and then turn one end over and stick it into Mobius tape.

Mobius belt was discovered by German mathematicians Mobius (1790 ~ 1868) and Johann Rhys Ding Yu (1858). It is a paper tape loop made by twisting a piece of paper 180 and then bonding the two ends together, which has magical properties.

Ordinary paper has two sides (i.e. hyperboloid), one front and one back, and the two sides can be painted with different colors; However, such a paper tape has only one surface (that is, a single curved surface), and insects can climb all over the curved surface without crossing its edge. This kind of paper tape is called "Mobius tape" (that is, its curved surface is reduced from two to only one).

The moral of Mobius ring:

The metaphor of Mobius ring is cyclic, eternal and infinite. Mobius band, also translated as Mobius ring or Mobius band, is a topological structure with only one face and one boundary. It symbolizes cycle, eternity and infinity. Therefore, it is often used in various logo designs, which means eternal and perfect love in the ring.

Mobius rings are very suitable for making rings. Mobius ring has only one side, symbolizing perfect love; As long as you like, the Mobius ring can circulate indefinitely, symbolizing reincarnation and endless love.
