Dizziness with magic tricks helps you see through the palm of your hand

Try looking at your hand and reply: What do you see? With this magic show, you will see your hand . transparent.

Perhaps the answer is too clear: see . the hand doesn't see anything anymore. But you know, there is a kind of hallucination that helps you see through your palm. And if you want to try that feeling, try a "magic trick" following the instructions below.

First, take a sheet of paper rolled into a round tube and look at one eye through the tube. After that, place your other hand on your eyes, about 6cm away from your eyes as shown in the picture below.

What do you see?

As a final step, look at the distance, don't look at the hand. After about 10 seconds, you will see your hand suddenly . have holes and can see through.

Strange, right? This illusion was posted on her Youtube channel by Vanessa Hill, an Australian scientist. And the secret of this game is based on a very basic phenomenon of the eye called: binocular rivalry.

Can understand simple as follows.We are not simply looking, but also receiving visual information through the eyes, sent to the brain for processing. Under normal conditions, the brain combines images from both sides of the eye to create different angles of the image, allowing us to feel the length, width and depth.

We are not simply looking, but also receiving visual information through the eyes.

However, in case of discrepancy in visual information from both eyes , the brain will prioritize the eye with stronger and clearer information. That is the phenomenon of two eyes, and this also explains why people who only get close to one eye can still see things clearly.

Keep coming back to our magic. When one eye is seen through the tube, the images are recorded by the brain as a concentrated image with a strong intensity, while the eyes looking at the hands are interpreted as images with rather weak signals. And so you will have a feeling that your palms are dimmed and like you can see through them.

The binocular concurrency phenomenon was first discovered in the 16th century by Giambattista della Porta, an Italian scholar. Over time, science and technology has helped researchers determine what happened to the brain now.

Specifically, information signals from the two eyes will initially be taken up by different brain regions. But in the later stages, neurons can turn these signals on or off depending on the weak strength of the information, leading to the resulting image being different.
