I am enjoying this discussion.
I would only do this trick for magicians anyway because there are so many better "effects" for lay people.
Can anyone suggest actual effects/routines that you think are better? That will help frame the discussion. I assume you are talking similar effects.
I have done this effect several times for lay people and it does get a good
reaction. Also, I am experimenting with doing it with a deck shuffled by
the spectator (FASDIU). It is obviously hard to load the cards face up
in the right position immediately after someone shuffles the deck.
Here's what I do:
* Start with two jokers face up on the bottom of the pack. You can easily
load these from your left pocket after a spectator shuffle.
* I say "let's try a small experiment with a small number of cards and to make
it fair, let us not use the top few cards". Here I count nine cards and place
them aside in a discard pile.
* Next I do Jim Steinmeyer's "Nine card problem" effect with a lie detector theme.
In order to do this I lay down 3 packets of 3 cards each (another nine cards).
* As they pick up the pile they chose and note the bottom card, I turn away. This
is part of Steinmeyer's effect.. Here I quickly count another
nine cards and load the first joker face up from the bottom
- mechanics are like a side steal, easy because you have turned away from audience.
* I turn around place my pack dowm and place the discard pile (9 cards) on this and
set this aside (FU joker is now 19th from top).
* After I finish my "lie detector" trick, I put those 9 cards on the top, hold
a break and load the second joker with a side steal. This is between effects while
I say something like "let us try one more experiment - a harder one".
Your jokers are now loaded and you can proceed with Aronson's excellent effect.
