Liu Qian's 20 10 Spring Festival Evening Magic Decryption

Before putting his hand into the glass, Liu Qian repeatedly wiped the glass very carefully, which can be considered as wiping off all fingerprints on the glass to prevent the glass from being discovered by the audience in front of the TV when it was rotating. Every action of a magician has a purpose, and he will never spend so long cleaning the glass for no reason. It is also the most reasonable guess that wiping off fingerprints is convenient for rotation.

2. 12 minutes 14 seconds, Liu Qian's left hand obviously moves on the glass, which completely conforms to the conjecture of pushing the glass.

3, 12 minutes 26 seconds, 12 minutes 47 seconds, 13 minutes 12 seconds, and so on. We can see that Dong Qing has been carefully putting his hands and arms on the edge of the table, not on the glass. In fact, including the man on the left, he has been careful not to touch the glass throughout the program. The reason is naturally to avoid leaving fingerprints and affecting the rotation of the glass.

4. 13: 08, Liu Qian's hand (arm) moved slightly to the right several times in a row, which can be inferred as the result of rubbing with his left hand when the glass turned back to its original position (and the glass returned at a fast rotating speed, otherwise it would not produce friction that Liu Qian could not control), which accords with physical common sense and completely meets the previous conjecture.

In addition, we must notice that at 12 minutes and 53 seconds, Liu Qian put the glass bowl that had knocked on the table on the upper left of the big glass in front of him, but after 13 minutes 10 seconds, we can see that the glass bowl has not changed its position. Therefore, it can be judged that not all the glass is rotating, but only the glass in or near Liu Qian is rotating. But this makes me a little puzzled, because there are no traces of glass splicing in the lens. Is glass cutting and splicing so good? Since cutting and splicing can be so excellent, why not directly use the third method analyzed above? Wouldn't that be easier? The answer may only be known by Liu Qian himself and the assistants present.
