Today we are going to learn a brand new, amazing and very easy card
trick. I name it the upside down trick, because I don't know any kind of
official label for it. So let's get started:
First you need to prepare the deck, remove all of the cards which
are identical from both sides, and leave the ones that you may make out if they
happen to be "Up" or "Down", what does it mean? Well, the
deck has many cards which are completely identical, face up or down, from
either side you look at them. Some of them aren't, for example, glance at the
ace of spades, the spade is pointing up or downward, some cards, such as the
7's have the majority of shapes aimed upwards or downwards. Pick the cards you
can discern between them, there should be 22 of these.
At this point the deck (1 / 2 of it anyhow) is prepared. The secret
as you might suspected is to place all the distinguishable cards with the
identical direction.
For the execution itself: Allow the spectator choose one card, or 2,
or 3. Now it's the most important move - when you take back his card\s reverse
them to point the contrary direction of the rest of the deck. Shuffle the deck
preferably using the overhand shuffle. Well, how you can finish the trick is up
to you truly, as you already can easily distinguish what cards the spectator
selected, those in your deck which are inverted :)
TIPS
You may let your spectator shuffle the cards after you have gotten
them from him and reversed them, to improve the trick, yet be ware he will not
change several cards himself, or maybe make some unusual shuffle.
Be
cautious whilst reversing the cards to avoid suspicion. Don't look at your
hands, look at your spectator and engage in some conversation while doing the
invert. You may invent your personal misdirection.
