A few weeks ago, physicist Andreas Wahl was hanging 14 meters (46 feet) off the side of rickety looking warehouse in the name of science. In his newest video, he appears to up the ante even further by using a loaded gun to test the power of fluid resistance.
Standing in a swimming pool, he fires at himself with an assault rifle less than 3 meters (9.8 feet) away using a string attached to the gun’s trigger. He still wears goggles, though – safety first.
The video is a snippet from a Norwegian science show on channel NRK Viten. As they explain in the YouTube 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.”
Their film crew used slow-motion cameras to capture the effect of the bullet’s force on the rippling water.
