He only used some basic tricks of magic (such as hiding a deck of cards in his hand so that the audience could not see it), plus clever devices and many exercises, and achieved the effect we saw. ?

Crack the angle, judge which hand is the hand that hides things, and then look at whether the hand that hides things is in contact with the desktop, the length of contact, and the time it takes to change things. When in contact, Liu Qian is diverting everyone's attention. ?

However, the arrangement of Liu Qian's magic in all aspects can be regarded as wonderful to the extreme, but it is not difficult to find some flaws because of nervousness. ?

One, coin glass. ?

Principle:?

Coins into the cup! ? There must be a mechanism under the tablecloth at the bottom of the cup! ?

1, as shown in figure?

There is a gap between the big cup and the small cup. The big cup is upside down, and the small cup is placed upright in the big cup. There is also a big gap on the desktop. The tablecloth is black, so that the exit switch action of ejecting coins from the tablecloth will not be found. ! ! Coins shoot into the mug from the table between the bottom of the mug and the mouth of the mug, then bounce off the wall and bottom of the mug twice and fall into the mug. ! ! (Inside the big cup, the inner wall with a big mouth and a small bottom is obviously not perpendicular to the desktop, so the coin bounces off the desktop vertically, changing the trajectory, then bounces off the bottom of the big cup and just enters the small cup. It can be seen from the violent shaking of the coin in the small cup that its ejection speed is very fast. The trigger of the mechanism of ejecting coins can be that Liu Qian's feet or some part of his body touches the switch of some part of the table, so that coins can be ejected from under the tablecloth. ?

Second, the egg ring. ?

The principle is similar to the former. ?

Principle:?

1, watch the performance video of the Spring Festival Gala carefully?

2. There are mechanisms under the desk and on the plate. ?

3. The characteristics of the egg liquid are: sticky (if there are any holes and cracks in the container, the egg liquid will not leak out) and sheltered. ?

4. It took 10 second from the time when the hidden hand touched the desktop for a long time (like the first magic trick, the ring was stuffed into the "coin slot" of the desktop) to the time when the host knocked the egg into the bowl, which was enough for the equipment under the desktop to be fully prepared. ?

5, the action of setting dishes can be said to have seized the opportunity, but some rushed to reveal flaws. The plate itself is very heavy, and there is something absorbing iron, iron bars or magnetism at the bottom of the plate. As you can see from the video, there is a circle of silvery white things at the bottom of the dish, mostly iron rings. There must be a circle of magnets or controllable electromagnets with the same size under the desktop, so as to quickly locate the position of the plate and aim at the orifice of the ring. Through the video, we can see that when the host picked up the egg, he quickly put the plate away, and the host didn't check the plate carefully! I can see him throwing the plate sideways on the table (I want the audience to see that it's natural, but it's not). After the plate landed, you could see signs of being sucked. First, it doesn't slide; Second, there is no sign of turning and flapping at all (the mouth of the plate is big and the bottom is small, so it may be very big to turn and flap after landing). Is it unnatural for the plate to land?

6. Egg yolk appears in the dish for more than 1 sec. I saw the ring move from the middle to the side. That is to say, from the moment when the yolk just touches the plate and blocks our view to the moment when the ring appears, 1 second is a little more, which is the time when the ring is sent out by the organs on the desktop and the bottom of the plate. ?

7. On the stage 1 second, thousands of times off the stage, I think Liu Qian really spent a lot of time on how to seize the time when the trigger switch sounded the bell from the bottom of the tray. ?

8. Why do you choose an inverted cone with a small bottom and a big mouth? Because we can't tell whether there is a slight increase or decrease in the egg liquid in the plate after the eggs are put into the plate. But look carefully, when the egg hits the plate, the liquid level drops a little, then rises, and the circle comes out. ?

9. The bottom of the board is movable and can be taken down! There is a magnet at the bottom of the dish to seal with the desktop, so that the egg liquid will not leak out after the bottom of the dish is opened.
