A set of limericks on Mobius strips

Take some paper that is straight
and try this, it's great!
Hold the end,
Give it a bend
A mobius strip you did create.

This strip has only one side
But physics it does abide
Out is in
It doesn't begin
Because of the twisted divide

Cut it all around
Straighten it on the ground
One piece you will see
In the debris
Unharmed by its wound
