1. Design "mechanism"
The "organ" is also the door of magic props. This can be designed directly with the principles of natural science. For example:
The "mechanism" of "wardrobe becoming a person" is designed by using optical principles. Two mirror plates are placed in the cabinet at right angles, and the lenses form an included angle of 45 degrees with the side wall.
In this way, the shape of the side wall can be reflected through the lens, but the shape of the back wall is replaced, and the assistant is hidden behind the lens.
When the audience looked at it, the inside of the cabinet was empty and the assistant behind the camera could not be seen.
In order not to let the audience see the mirror behind, but also to facilitate the presence of assistants, further camouflage is needed.
The "three points of human body" is designed by using geometric principles. It is no secret that three wooden cabinets are divided into upper, middle and lower cabinets.
When the magician pushes out the wooden cabinet in the middle, the wooden cabinet will automatically form a straight interlayer, and the assistant's waist is hidden in the middle of this interlayer.
Due to the accurate calculation and ingenious design, coupled with the beautification and camouflage of props, the audience seems to think that the mezzanine is too narrow to hide people, and they have to believe that the assistant is divided into three sections.
The "knife box" is to put the assistant in the box first, and then the magician will stab a dozen steel swords from the front, back, left and right respectively.
In the eyes of the audience, the bronze sword is so tightly inserted that the assistant can't hide in the box. It really made the people in the box sweat.
In fact, it is entirely possible. This prop is designed to insert the steel sword into the box according to the assistant's figure and geometric principle.
The perforated steel sword forms a three-dimensional geometric figure in the box. Although it is tightly inserted, there is still a certain gap to accommodate the assistant's body.
The hanging man on the knife is designed by using the principle of mechanics. The magician was seen to put his assistant on three sharp knives first. When the magician removes the knife from his feet and waist, only the tip of his neck supports the assistant's body.
Why didn't the assistant's feet and waist fall off? This is because the center of gravity of the auxiliary is still within the range of the base plane. In order to do this, the size of the auxiliary armor and base should be calculated accurately and designed reasonably.
The candle in the candle spontaneous combustion is special. It uses the principle that the resistance wire burns red and heats up after being electrified, so that the candle is automatically lit; When the candle is lit, the "timer switch" is skillfully used.
The change principle of steel needle balloon is to use the physical characteristics of the balloon itself, without any props and doors.
After the balloon is inflated, its wall will become very thin and it will explode when it is pricked with a needle. However, the top and root of the balloon have not changed much, and there is still a certain thickness, and the resilience is still relatively strong.
Therefore, if a steel needle pierces the top and root of the balloon, the balloon will not explode. In fact, the audience is not familiar with these characteristics, so they are puzzled.
Make props
Making props reflects the application of science and technology, and can better reflect the convenient conditions provided by science and technology.
For example, "walking stick escape" is a prop made by heat treatment using the elasticity and mechanical properties of special steel. Can bounce off or contract at will. Without modern science and technology, this can never be done.
The program "Private Telegraph" illustrates this problem even more. This is the use of high-frequency current and radio waves and other related equipment, completely dependent on radio technology. Therefore, without modern high technology, there would be no such program.
3. Performance method
A lot of scientific principles are also used in the performance method. Such as "tea discoloration", that is, putting ferrous sulfate into tea leaves, the tea leaves turn black; Then put citric acid into black water, and it becomes tea again. This is mainly done by using chemical principles.
Poker tricks such as "drawing cards" and "guessing cards" are all done by using mathematical principles. There are also some magic shows that take advantage of the audience's psychology.
