Physicist risks gunshot underwater for the sake of science

An amazing video shows how a physicist braved gunshot underwater to prove science

Daredevil Physicist Andreas Wahl in his video has proved how the velocity of a bullet slows down when it’s fired underwater unlike in movies and video games where it is shown that the bullets travel in a straight line. Wahl decided to test it by putting his life on the line in the name of science in a lovely visual experiment.

The video posted by Wahl on YouTube shows him standing in the middle of a swimming pool holding a string that will pull the gun’s trigger aimed at him from 1.5m away. When the string is pulled, the bullet bursts out of the gun with as much power as it would above the surface. However, it does not even come close to hitting Wahl. The video shows that the bullet loses a lot of its momentum before it sinks to the bottom, which is not even halfway to its mark. And the reason for this is due to resistance underwater.

According to the video, “It’s harder to create movement in water than in air, because water molecules are closer together than air molecules.”

We all are aware that it is difficult to move in water than out of it but the extent to which it slows something as streamlined as a bullet is far more impressive than one can imagine.

Check out the video below to see Wahl’s impressive experiment with the underwater gun.

  1. The thing is this…..if you’re being threatened by someone pointing a large gun at you, what are the chances of getting them to agree to adjourn to the swimming pool before they then get frustrated to the point of pulling the trigger ?
