The Secrets of Moebius Tape

Try to make a Moebius ribbon by cutting a strip of paper and using tape, glue the ends of the ribbon together like a "bracelet", but turn it 180º from one end of the tape before joining.
They thus obtain the Moebius ribbon, which has interesting characteristics one of them is to have only one surface as we will prove next.
Try using a pencil to start scratching along the tape, so check that when you have reached the starting point you have completely scratched the entire surface (apparently on both sides, which is really only one).
In mathematics, a non-orientable surface is called the whole surface on which one can walk, and on returning to the point of departure we find ourselves at a point which is the image reflected from the surface.
Another interesting experiment will be, using the scratch you did earlier and scissors try to split the ribbon in half, so try to create 2 ribbons (2 bracelets).
The result will be a tape with twice the perimeter.
On this second tape, repeat the procedure.
You will get 2 tapes attached as if they are 2 links of a wire. There are those who think this proves that there may be "Dimensions" within "Dimensions" interconnected with each other .........
