Backpalming a Card
Called Backpalming or back palming, learning this magic trick is a must for any magician.
Print this page, bookmark us, but you simply must spend some time and
learn this magic trick! David Blaine, David Copperfield, Jeff McBride
and countless other professional magicians do this. You can too!
Effect:
You can throw cards up into the air and they magically
disappear!
Secret:

Start with one card, and eventually you can move onto
more. Hold the card between your thumb and index and middle fingers.
Have the face of this card toward the audience.

Pretend to throw it up into the air. As you do this, make
a fist. Let your fingers slip behind the card, so that now your thumb
is pressing against your knuckles and is now holding the card.

Press the two long edges between the knuckles. Your first
and middle fingers will hold onto the top long edge, and your little
and ring finger will hold onto the bottom edge. Don’t worry about bending
the card bigtime here.

Release with your thumb and outstretch your fingers. Keep
hold of the card. It should now disappear behind your hand. (This is
an exposed view. When you do this, keep your fingers together, and slowly
keep your hand in motion.)

It is okay if the corners show a little, just keep your
hands moving up and down.
To grab a card out of the air, just reverse this process
and you can do this several times in a row.
Here is what it should look like from the back:

Will Smith did this in the Men In Black music video.
You can also do this with business cards to impress clients.
