Video: Being shot from a distance of 2m from the gun is still safe if you stand in the water

Although it was only 2 meters away from the barrel, when the bullet shot out, the person was still safe.

Under water, the density of water molecules is thicker, from which the resistance will be large and the bullet will only move a short distance.

It was an experiment by the physicist Andreas Wahl who used himself to demonstrate the great resistance to moving objects in the water environment, and to decode shooting scenes to create water. into long tracks that often appear in action movies and it turns out, that is only true in movies, not in real life.

If on the shore, the density between the molecules in the air is low, the bullet is less resistant to friction, thereby flying further. Under water, it is completely different, the density of water molecules is more dense, hence the resistance will be large and the bullet will only move a short distance. On the other hand, firing a bullet containing underwater gunpowder was possible because the gunpowder was sealed in the cartridge and also contained enough oxygen to explode and pushed the warhead out of the barrel.

Add video to shoot bullets under water spinning at 27,000 fps.

So what if shooting bullets from the shore to the water? In action movies there is often a scene where someone is being chased, then jumps into the water and then the shots of bullets flying straight into the water form long streaks. Is that true? Remember two brothers Jamie and Adam on the Discovery Busters program of Discovery channel have done experiments to decipher this.

Experiment shoots bullets into the water in Discovery's MythBuster program.

In the experiment, they used a gel-shaped mirror with the same size and weight as humans, then drowned in the water. They then used a 9mm bullet gun and a 12 gauge bullet shotgun (18.5mm caliber) to shoot at water at a 30 degree angle. And the results showed that the bullet almost stopped after walking about 1 meter after touching the water. And the results are more surprising if a M1 Garand semi-automatic rifle is used with bullet speed of about 853m / s. But when shot into the water, the bullet was immediately pulled back by the resistance of the water extremely quickly, leading to burst.

Therefore, shooting scenes like watering in Saving Private Ryan or Spy 007 , . is just an effect to create more dramatic but in real life, just need to be 1 meter or more deep in the water. Downed bullets will also be hard to hurt or die.
