Scientists risking their life to prove Physical law

Physicist Andreas Wahl in the video, is letting himself be dropped 14 meters towards the ground, because he knows that things rotate faster when they approach a central point…

Therefore, he only attached to a loose rope with a weight at the other end.

Fires weapon under water, with his own life on the line:

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.
