1, complex technology: Magic shows usually involve complex skills and props, which require high technology and are difficult for the audience to understand and follow.

2. Communication restriction: When performing on TV or stage, the communication between the audience and the magician is restricted, and it is impossible to ask questions or interact with the magician in real time.

3. Repeatability: Once the audience knows the scientific principles or magic skills behind it, they will lose some mystery when watching the program.

4. Safety of chemicals and props: The magic show will use chemicals and props. Attention should be paid to ensure the safety of the audience and avoid accidents or injuries caused by improper use.

5. Lack of depth: Due to the limitation of program duration, it is difficult to deeply explain and discuss the scientific principles behind magic.
