Interesting Mathematics
with two strips of paper
Take two strips of paper and create two Möbius strips. Make
sure that the strips have different orientations. This is done by giving one strip a right (clockwise) twist and the other a left (counter-clockwise) twist.
Glue the two pieces together so that at they form an angle of 90° at the join.
Now cut along the middle of the strips. To help you, you might want to draw a line on the strips before starting the gluing process.
Pull the pieces apart and let them take their natural form. Voila! An instant love letter.
As far as I know, nobody has discovered this cool result before me.
