How does a coin trick work from behind an ear?
Sleight of hand and no fraud. For a coin to appear unexpectedly behind the ear of the viewer, the plasticity of the movements of the hands, their speed and mathematical calculation of time are needed - the coin must suddenly disappear and also appear. At some point, a coin should be reset from fingers to palm, this is achieved only by training.
For the trick, you need to ask the coin for a trick, and it still needs to be the same size that you are used to training with, which your fingers are used to. The coin is taken with the thumb and forefinger of the left hand, we play at the public, show it, hold the palm upright, everyone sees the coin. After lowering the right hand over the left, supposedly you want to pick up the coin when the fingers of the left and right hands are on top of each other, relax the fingers of the left hand and lower the coin into the palm of your hand (make a French reset). At the same time, we squeeze the fingers of the right hand, as if a coin is in it. We follow her eyes, we take our hand aside. The movement of the hand and your look behind it distracts the audience and they are sure that the coin is in the right hand. At the same time, the left hand is already down. Open the palm of the right hand - it is empty, there is no coin in it! You are looking for a coin, go to the viewer who gave it to you. Move your hand over his head, behind his ear - at this moment, you need to push the coin with your palm towards your fingers so that it touches the ear. And we show the coin at the beginning of the trick, clamped with the thumb and forefinger.
