Sit sideways to your audience. You will need to sit this way in order to create the illusion of disappearance.
Decide if you are right hand or left hand dominate and lick the top of the thumb of your dominate hand. The top of the thumb is where you find the nail.
Grip a single cigarette between your thumb and index finger in your right hand. Place the cigarette in your hand as if you were putting it to your lips to smoke.
Hold your left hand in front of you with the palm facing up. This hand is actually a distraction for the audience-it has nothing to do with the trick. You will hold the cigarette in your right hand over the palm of your left.
Jerk your right arm and hand in a motion that moves towards your mouth. You want the audience to think you are tossing the cigarette into your mouth.
Raise your right hand that has the cigarette to ear level and then make a hatchet motion towards the left palm.
Utilize the distraction of the left hand-repeat the hatchet motion and count 1, 2, 3, 4. Slip the cigarette behind your right ear while the audience looks at the left palm.
