I'm looking for more information on a trick I bought at a magic shop in Tampa. The name of the trick in the instructions is Jim's Magic Bolt Trick, and the effect is:

Place a card on top of a rectangular piece of Plexiglas with a hole drilled through both. Align the holes and insert a hex head bolt through both followed by threading a nut on the bolt to hold it all in place. Then you can pull the playing card straight off the block, seemingly melting through the nut.

The trick came with six playing cards: KD x2, QD x 2, 6D, 5H. The instructions are very vague and don't include a manufacturer name or any recommended routine. Why the different values of the cards? Is there more to it? Has anyone seen this one?

Could it be to give you different choices of force cards?

I suppose that’s an idea, but forcing the card wouldn’t have much of an impact if all you’re going to do is make it the focus of a melt-thru effect. It’s been my experience that you can only attach one card to make it work anyhow. It just seems like the finished effect that I bought was a hodgepodge thrown together so the shopkeeper could make a quick buck, but I enjoy it nonetheless because of the clever melt-thru method. No one suspects it.
