In this magic performance, the performer takes out two five-cent coins from the pocket (it's better to borrow the coins from the audience) and shows them to the audience. The performer holds one coin in each hand and at the same time knocks on both sides of the table with the coins to show that there's no trick with the table. Then he gesticulates over the right fist with the left fist and lays open the right hand, letting the audience see the coin still in the right hand. After that, he does in the other way round.
Then the performer puts the left fist under the table, draws a small circle on the table surface with the right fist and smacks the circle hardly. With a clap, he turns open the right hand -- the coin is gone. Finally, he puts the left hand open on the table and the two coins appear in it. This shows that the coin in the right fist has penetrated the table and reached the left hand.
The magic requires two five-cent coins that look the same. The performer holds one coin in each hand and knocks at the table. After knocking under the table with the left hand, he puts the coin in the left hand on the thigh with the coverture of the table and then moves the empty left fist onto the table. At this moment, the performer fists two hands with the right one facing upwards and the left one facing downwards. After he gesticulates over the right fist with the left fist, he quickly lays open the right hand so as to let the audience see clearly that the coin has not been moved.
Then he fists the right hand and changes the gesticulation with the right one facing downwards and the left one facing upwards. When he gesticulates the right fist over the left fist, he slowly relaxes the right fist and the coin leaks into the left hand. At the same time, he tightly fists the right fist and quickly lays open the left fist to show the coin is still there. In fact, the right hand is empty -- the coin has been moved to the left hand and the other coin is still on the thigh.
While he draws a circle on the table with the right fist, the performer attracts the attention from the audience and takes the opportunity to grasp the coin on the thigh with the left hand. After that, he nips the coin with the thumb and the index finger and hits hard under the table, making a ringing sound in coincidence with the clap from the right fist knocking on the table surface. This produces a wrong impression of hearing and vision on the audience and they think the coin has penetrated the table.
This magic is quite simple but can produce interesting effects. The performer should take every opportunity with a sleight of hand to produce hallucination on the audience.
