Physics teacher shoots himself underwater to prove ascientific principle

Physicists love conducting strange, if not wholly
bizarre and seemingly dangerous, experiments in
order to showcase whatever scientific principles
they’re trying to

impart to students or the public at large.
Most recently, physicist Andreas Wahl decided it’d be a grand idea to hop into a pool with a loaded gun and, you know, try to shoot himself underwater. Of course, given that water is much denser than air, Wahl’s underlying point was that he wasn’t really putting himself in danger at all.
Still, it takes a whole lot of guts to go through with a maneuver like this.

Wahl set up a gun underwater and affixed it with a string so that he could pull the trigger himself.

 A slow motion camera strategically positioned adjacent
to the gun captures the entire chain of events in crisp detail.
“It’s harder to create movement in water than in air, because water molecules are closer together
than air molecules,” the YouTube description
reads. “To show the difference in resistance,
physicist Andreas Wahl puts himself in front of a
weapon submerged in water and fires it – on himself.”
Of course, this isn’t the first time we’ve seen
someone employ a gun in order to prove a
point. Even a cursory glance around YouTube
reveals no shortage of videos featuring people
wearing bulletproof vests purposefully being shot at close range.

demonstrates Newton’s second law of circular motion.

NOTE:

Wahl wanted to explain Newton’s
second law of circular motion and how
objects with a centripetal force (which
compels them to travel in a curved
path) spin faster as they reach a central
point. So, from a pole at an abandoned
Norwegian warehouse, he hung 14
meters (46 feet) in the air without any
sort of safety equipment, attached only
to a rope with a kettleball on the end.
Theoretically, as he fell, the rope with
the weight would spin around the pole
to which it was attached faster, and
essentially get caught in time to prevent
Wahl from hitting the ground.
