A lot of dangerous, some may say ‘fool-hardy’ experiments have been conducted in the name of science and the one above could easily be included into that bracket.
Physicist Andreas Wahl bravely demonstrates how water slows the trajectory of a bullet down, once fired from a submerged gun, by standing directly in front of it. The science behind this experiment is explained succinctly in the video’s description:
It’s harder to create movement in water than in air, because water molecules are closer together than air molecules. To show the difference in resistance, physicist Andreas Wahl puts himself in front of a weapon submerged in water and fires it – on himself.
