The Physics of Origami: Can It Be Applied to Playing Cards?

[sk8bordgeek]

I came across this piece of origami a while back and was wondering about the physics behind it. When dropped, it always lands face up. http://youtube.com/watch?v=_ZszGCK4R54" Can the same principle be applied to a playing card (I'm a magician).

The origami works best when the three "points" are crimped so as to be asymmetric; then it is very unstable when it is "upside-down", either way it will be totally stable when it is "face-up".

It is more difficult to do this with a playing card, because you have to crip all four corners in an asymmetric way.
