A dedicated scientist showcased the wonder of physics by attempting to shoot himself underwater.
Physicist Andreas Wahl stood in a pool with an assault rifle aimed directly at his chest on the other side of the pool.
A string was tied to the trigger, allowing Wahl to fire the weapon himself.
The bullet was released with a thunderous boom but apparently sank less than halfway between the gun and Wahl.
The YouTube video's description explains,
It's harder to create movement in water than in air, because water molecules are closer together than air molecules.
According to Daily Mail, the bullet exited the gun with the same speed as if it was fired on land, but it sank because water is 800 times denser than air.
Wahl previously risked his life in several other scientific experiments.
He reportedly tried to light himself on fire after soaking his body in water and threw himself off a high point while attached to just a thin rope.
