A model can easily be created by taking a paper strip and giving it a half-twist, and then joining the ends of the strip together to form a single strip. In Euclidean space there are in fact two types of Möbius strips depending on the direction of the half-twist: clockwise and counterclockwise. The Möbius strip is therefore chiral, which is to say that it is "handed".
now run your hand along it, and it is never ending... maths is fun!!! its actually one sided.... how bizarre! next time, i'll teach u more in dawsons wonderful world of maths and science
