Viral in X: They claim people in this video “stop moving” if you shake your phone

Optical illusions are a classic. They have existed on the Internet practically since its inception and never cease to amaze us. If you don’t see the video that made the account go viral @PicturesFoIder in the

“Shake your phone and people will stop moving“, promises the user. And in doing so, all said and done: people moving from one side to the other remain static.

The video, recently viral thanks to the account @ PorqueTTarg, accumulates more than 29 million of reproductions in X. A titanic number.

In the comments it is clear that there are many who were surprised by the test results. Because it is worth clarifying that the video does not stop. When you shake your phone you should do so while the video is playing.

Many have also tried to do it on the monitor and found that it doesn’t work: in that case it doesn’t work.

There were also those who noticed that the flashlight on their cell phone turned on and off every time they shook the cell phone…

The optical illusion that tricks the brain

The above is not the only optical illusion that has gone viral in recent times. On TikTok, for example, a similar video appeared in mid-2023 and attracted the attention of thousands of people.

It seems very easy to solve and yet it manages to trick the brain. A simple question is the trigger: What color are the eyes of the woman in the video?

The answer that comes immediately is “blues”. But this is not the case, and surely those who accepted the challenge were the victim of a surprising optical illusion, as it turns out that the model’s irises are actually grey.

The trick was shared on TikTok by the illusionist Dean Jackson (@beatonthebeeb), who explains how it works.

“Your brain detects the pigment, the gray area around the pupil, and assumes that the red filter has trapped the blue light,” the illusionist explains in one clip.

“So it’s trying to help you, as your brain is supposed to do, by reintroducing the color blue into your image, and your brain is completely tricking you in the process,” the argument continues.

At the back of the human eye are photoreceptors, cells that respond to incoming light. These are of two types, “rods” or “cones”, and while the rods are sensitive to motion and night vision, the cones are capable of detecting colour, spreading for 20 minutes.
