Science - Fire weapon under water - at your belly

submitted by Zawash

8 years 3 months 2 weeks ago

YT: 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.

In the Norwegian TV show "Med livet som innsats" (Life on the line, lit. "With the life at stake") physicist Andreas Wahl puts his own life on the line, trusting 100% on Science and the Laws of Nature to save him, with no safety net.

Here, according to physics, a bullet fired from a high-powered assault rifle should safely slow down and not kill you if fired from a couple of meters under water. Safety nets are for sissies.

plop plop ping ping ... oh what a relief it is/was!

"life on the line", i say OH please, as if he didn't know EXACTLY how far was a safe distance. He was more than twice as far as the bullet fell to the bottom (bullet fell at 14 bars of the 30 where he was) And at the end he acts all relieved as if he had been taking a chance. BOOOOO

There's a difference between knowing it's safe and feeling safe while doing it.

We've secretly decreased the density of the water in this pool, let's see if Andreas notices a difference...

Good point. Example case is the bowling ball pendulum
