Try this . . . .

1. Cut a one inch strip off an A4 sheet of paper (long side).
2. Twist it just once then stick the ends together.
3. You now have a Mobius Strip.
4. Now with a marker pen or crayon draw a continuous line along the middle.
5. You will end up with the continuous line on BOTH sides because there are no longer two sides, only one!
6. Now cut the strip in half longways, only trouble is you can't separate the two loops which will be interlinked.

You have now entered The Twilight Zone . . . .
