Foreign men put their arms into a vacuum environment, and their arms seem to be about to “explode”

Recently, Xiaobian saw such a video on the Internet: a foreign man “vacuum experience”, put his arm into a professional container, and then vacuum the inside of the container. It has to be said that foreigners’ brain holes are really big.

As we can see from the picture, this is just a few seconds after the foreign netizen started the experimental instrument. The man’s arm has been congested and red. It seems that the situation is not as “comfortable” as expected.

The degree of hyperemia in Figure 2 is much greater than that in Figure 1. You may think that it took a long time from Figure 2 to figure 1. In fact, it took only a few seconds. It took less than 10 seconds from the beginning to hyperemia and swelling.

The netizen obviously couldn’t support it, so he bent down to shut down the machine. In the picture, we can see that the man’s arm inside the container is not the same color as his arm outside the container.

The man successfully stopped the machine and took his hand out of the container. There was a clear color line on his arm. It was only a few seconds from the beginning to the end.

In addition, Xiaobian reminds us that the pressure in the human body is equal to the atmospheric pressure, which is why we can live freely in the air. If we take away all the air around us, we are likely to die because the pressure inside our body is greater than the external pressure. So in the picture, we can see the swelling of the man’s arm. The above behavior is a little dangerous, so we should not try it easily.
