For this magic trick, Dong Qing is actually a trustee, because the magic does not involve issues of professional ethics. It only needs to give the audience a surprise. Dong Qing signed two coins. Of course, the font and style must be similar, in private. The signed coin had already been given to Liu Qian. Liu Qian put the coin on a spring mechanism under the table. There was an exit on the table, which was large enough for the coin to pop out sideways. This exit was very hidden and relied on two aspects: 1. It is the color of the tablecloth, which is dark. Secondly, there is a lot of fluff on the tablecloth, which can effectively block the exit. The position where Liu Qian placed the small glass was very important. He seemed to put the small glass on the table very skillfully, but in fact he placed it very carefully next to the outlet. This position should make the coin outlet at the base of the small glass. and between the rim of the large glass. Liu Qian can use his right hand or foot to activate a hidden switch to cause the spring mechanism to eject the coins. We will not think about this mechanism because it does not require thinking at all. It is not the key to magic. After the coin is ejected, it passes through the gap between the rim of the small glass and the inner wall of the large glass, rises to the base of the large glass, is reflected back, and falls into the small glass. Due to the fast firing speed of the spring, the rising process of the coin cannot be seen with the naked eye. People are just surprised to see the coin instantly inside the small glass. Some viewers may ask, where did the coin held in Liu Qian's left hand go? It's actually very simple. As mentioned earlier, Dong Qing was a supporter. The coin was held by Liu Qian behind his left hand. He made a fist with his left hand, with the center of his fist facing down. With a flick of his finger, the coin fell to the table! ! ! ! Then he kept his fist, moved forward and turned his fist upward. When another coin fell into the glass, he spread his left hand. Of course, the palm of his hand was empty, but throughout this process, the coin was always on his left wrist and forearm. on the desktop below! ! ! It's just that the audience can't see the coin from the camera's perspective.

The whole process was over. Liu Qian straightened up, placed his left hand with the palm down naturally, placed it on the table and slid it to the left and back. In fact, the coin was pressed under the palm of his left hand, and the coin was slid to the corner of the table with his palm. , the corner of the table was blocked by pens, napkins, glass plates and other debris, and the coin could not be seen at all!
