Hi:

Anyone here ever use Corvello's "Will Power"? (Tannen's and Supreme Magic catalogs)

Miniature playing cards clipped onto a flat stick or "ruler", and each end of the ruler is held in the crotch of a spectator's two thumbs...their thumb & fingers slide along the ruler, and each time they unexplainably STOP at one card...their selected card, etc.

I have the instructions, but not the prop. I always thought this would make a nice bit of "bizarre magic" (and being so old, that the trick is new again).

...but just how practical is the prop?

Anyone have one to sell?
