This is so obvious I'm sure it was only left out of the write up for space reasons. But I thought those interested in this trick -- a group which based on this vibrant thread doesn't even include Richard Sanders -- might want to hear it.
Force a card -- say the 4 of clubs -- and let the spectator shuffle it into the deck. Take the deck and look through it, under the guise of finding the spectator's card. Move a bunch of cards around, pretending to consider them, etc., but really getting the ten of clubs to the top, the six of clubs second from top, and the four on the bottom.
Say you're done, and hold the deck face down.
Turn over the top card and ask the spectator if their card is the ten of clubs. They'll say no.
Ask them what card they did select. They say the four of clubs.
Say, well, I've got four clubs here. I just need to get them on their own card.
Now do Splittant, pulling the selected four of clubs from the ten, which turns into -- what else -- the six.
Without changing any of the handling, I think this presentation adds just a bit more meaning to this fine trick that all of David and I are talking about.
