20 1 1 the secret of Ding Jianzhong magic crossing in the Spring Festival Evening.

The thickness of the mirror is about 8- 10 cm, and there is a movable sliding door in the middle of the mirror (just like some bathrooms at home). This trick may be a one-sided sliding door.

When the assistant delivered the black box, the magician reached out from the middle and pushed the sliding door first. The sliding door has a spring, and the mirror automatically bounces back when people pass by.

A left mirror (with black cloth in the middle hole for performance), a front mirror (complete), a back surface (with holes in white), a front frame (which can rotate with the central rotating shaft), a left frame (with the rotating shaft in front of the left side) and a right frame (with the rotating shaft in front of the right side). Methods: Rotate the front frame 90 degrees to show the thickness, and then rotate it 90 degrees to expose the white back. At this time, the front frame. After crossing, the front frame is rotated by 90 degrees, and then the back is exposed by 90 degrees. The rear perforated mirror (left mirror) returns to 90 degrees to the left, and the complete mirror (front mirror) returns to 90 degrees to the left. The magic of crossing again is three layers of glass, which can be separated electromagnetically. Like a door or a textbook, you can turn the page upside down and overlap the inner side wall of the box behind: the first layer, the second layer and the third layer-the first layer is normal glass, that is, the audience can start. The second layer of glass is treated glass. When the first layer is removed, it can slide to the position of the first layer. This layer of glass is a prop, which is made in advance, similar to the first layer of glass after pasting a note and an outer frame, except that its outer frame covers the openable valve of this layer of glass. Actually, the third layer of glass is useless. It is ordinary glass used to cover the second layer of glass. Like the first layer of glass, it can be separated electromagnetically and attached to the inner side wall of the box, which is why the inner side wall of the box is so big. -The magic has begun. When the magician finished processing the first layer of glass, he turned the mirror over and looked at the third layer. At this time, the first layer of glass is turned over and overlapped with the left inner side wall of the box, and the second layer slides to the first layer. The glass turned back and the magician blocked the cloth. Then the magician took the photographer to see the back. As soon as the camera came back, the magician quickly stepped aside and let the third layer of glass turn over like the first layer of glass, overlapping with the right side wall of the box. At this time, only the second layer of glass is left. The magician opened the shutter and turned it around. After a while, the shutter returned to its original position. The third layer of glass returns to its original position synchronously, the glass turns over, then the prop glass returns to the second layer position, and the first layer of glass is reduced synchronously.
