Matching The Signs
The performer and
spectator each take five ESP cards, one of each symbol. The
spectator is told to arrange the cards face down in any
order desired. The performer turns away while this is
being done. Once the cards have been laid down, the
performer takes his five cards and deals one onto each of
the spectator's cards. When the pairs are turned
over, it is seen that the performer has matched each of
the symbols perfectly.
Method - To accomplish
this effect, you will have to mark ten of your ESP
cards, two of each symbol. If you're using the standard
ESP cards with the starry background, here's a
suggested marking system. If you look closely at each of
the short ends on the backside of the card, you'll
see that there's a subtle difference (this also
creates a 'one-way' pattern, which we'll exploit in
another effect). On one end, there are a number of stars
cut off by the edge of the card. At the other end,
there are only two stars cut in half. That's the half
we'll be using for this marking system. If you ignore
the two stars that are cut in half, there are five
whole stars in the next 'row' two on the left, two in
the middle and one in the right-hand corner.
Keeping our methods consistent, we will consider the
circle as one (one line), the plus as two (two lines),
the wavy lines as three (three lines), the square as
four (four lines) and the star as five (five points).
To indicate the circle, take a pencil and lightly
gray in the left-most star on both cards. For the plus
cards, do the same with the star located second from
left.
Continue this system for the remaining three
symbols. Make sure that you only darken the star just
enough so that you can distinguish it from the others.
If the mark is too dark, thus obscuring the symbol,
the mark is very obviously noticed because of the
regulated pattern.
It should be obvious by now that no
matter how much the spectator mixes his cards, you can
easily match the pairs.
