I love this effect. Have the spectator choose a card and sign it if you wish. Then the card is "lost
in the deck" before the magician spreads them all over the floor (or in a ribbon spread if you
prefer the neat look). The magician passes his hand over the deck and one card begins to move. When
it's collected and turned over, it's the signed card. Thinking invisible thread? Think again. This
effect can be performed with the cards poured into a sealed Zip-loc bag and it will still work. And
they get to keep their signed card to examine forever...because they'll never find anything wrong
with it since it's just a normal, signed card.
While I like the handling Jeremy uses for
the gimmick, you'll probably come up with the same idea I did when you watch the video. There's
something else you might already own if you're into PK magic that will do the same thing and allow
this trick to be almost completely impromptu (provided the right color deck is being used and you
have your gimmick on you).
For a wonderfully spooky effect that will blow your spectator's
minds, this is great. And you end fairly clean with the ability to repeat the effect immediately if
you so desire.
