This is Andreas Wahl, a Norwegian physicist and professional communicator of science and defier of death. He uses science to taunt the grim reaper in physics experiments designed to entertain spoiled kids who can’t learn by reading a book. Whatever his motivation, he risks (not really) personal injury to demonstrate various scientific laws that govern our universe. Banking on the knowledge that things rotate faster when they approach a central point, watch Andreas let himself be dropped 14 meters towards the ground – only attached to a loose rope with a weight at the other end. In this experiment, Andreas shows how 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, he puts himself in front of a weapon submerged in water and fires it – on himself.
