Reveal and remove a signed, selected card - with a bolt attached to the deck!
Show a deck that has a hole in the center of each card
Your spectator selects and signs a card
They mix the deck, which is randomly spread on a table, and place their card into it
Gather the deck, put the bolt through the holes, and attach a nut to fasten
Even with the bolt going through the cards, the performer finds the card with the signature
The spectator pinches the card, the magician casts a spell, and then the card magically passes right through the bolt - the center hole is not torn in any way!
