How To Throw a Playing Card:

1) Find a good card. The plastic coated ones work best.

2) Put the arm you plan to throw with in front of you, with your elbow bent at a ninety degree angle.

3) Grip the card with your thumb and ring finger, and place your index finger on the corner furthest away from your hand.
4) Bend your wrist so that the card is closest to you.

5) With one solid movement, snap your wrist in a frisbee-throw type of motion and release the card at the peak of this movement. Do not use your elbow.

6) At the moment of release, push your index finger back towards your hand, which should spin the card.

7) The card should not travel fast, but most of its movement should come with the spin.

8) After enough practice, this technique should be able to pierce paper, fruits, skin, and even drywall.
