Today, on May 3rd, we invited President Li Enming to study in the Guanshan Elementary School for teacher studies. This theme is related to the sun. For example, why the color change beads are changing color and what is blue. The color -changing pearl contains a sensitive coating. Under the exposure of ultraviolet rays, it can absorb the energy of ultraviolet light, open the sensor keys, and then transition to the high energy level after absorbing the energy of ultraviolet light. At this time After a period of time, it will fall back to the low -energy order. When the electrons return to the base state from the inspiration state, the light of different frequencies will be released, because some of the light is visible, and the gray -white beads become a variety of different colors. Beads. Blue sun is actually a traditional technology called "Blue Printing". In fact, it is a blue precipitation generated after the mixing of the ferrite and red blood salt. This technology often appears in the design of the building industry. The architects are called a blueprint. Because the presentation of the blueprint needs to be exposed to sunlight, it is generally called "sun -blueprint", so after the teachers' hands can be produced, a variety of patterns can be generated.
