Effect:
You can throw cards up into the air and the magically dissapear!
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 dissapear 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 video.
