How to judge whether the mirror is “normal”

The incident has attracted public attention, and many people are thinking about how to simply distinguish whether the mirror is “normal.” Some popular science articles are introduced that if you touch your fingers on the mirror, if there is a gap between the mirror and the fingers, it indicates that it is a normal mirror; if the mirror and the fingers have no gap, it indicates that it is a single lens.

As long as you add a layer of glass in front of the two -way mirror, or the coating in the middle of the glass, the “finger method” is not spiritual. According to the guidelines of the “two -way mirror”, the observer must be in a very bright environment, and the person behind the mirror is in the dark to achieve the effect of “peeping”. Therefore, compared with the “finger method”, a more effective method of judging is: turn off all the lights, use the flashlight to resist the mirror, or use the eye mirror, the hands to block the light, and take a closer look at the glass mirror.
