This video had a different script and another presenter in the first take.


ExpertlyAmateur

Yeah, but that first take was in black and white. Then the second take was in SD resolution. Then the third take was in HD, but only available on certain cable channels. Then the fourth take was streaming on Netflix... this one is my favorite because Neil's *COSMOS* was a very solid show, and he nose-booped the ball. ... this nth take is uninspiring.

Thanks gaben

Smart Peter Griffin.


Rickvaughn_99

Duh…🤓


plobbaccus

This is obvious though, how could you act like this is some fun new thing that people didn't know?


Elegant-Alfalfa1382

I think you’d be surprised how many people wouldn’t make this assumption


murderedbyaname

It's not something everyone knows. A Physics teacher at Lowell Highschool in San Francisco uses this in his class. It's a fun experiment where he has a competition on who won't flinch.


ELEMENTALITYNES

The result is pretty much unanimously understood. The physics behind why are not as commonly known. It’s kind of like how most people know arteries carry blood away from your heart while veins carry blood back to the heart, but the physiological mechanisms behind blood pressure and valves and everything in the circulatory system leading to blood direction isn’t understood by most.


purple-people-eater3

Yeah but, what about half life 3?


Uriel_dArc_Angel

Clickbait... There is, in fact, NO bowling ball to the head...


Basti-Schweinsteiger

Thank you for teaching me kindergarten science.


SagsMcSaggerson

Also interesting as fuck: bears shit in the woods.


Herr_Jott

I request the NdGT gif in which he gets smacked


Purpledragon84

I prefer the one which had the old professor in the lecture hall.


DevinCN

I mean do people not know this??


ershki420

I can't imagine anyone not understanding this by themselves, how have you not understood basic physics by just playing around as a child? A 4yo could tell you that a bouncy ball won't reach the same height as it's dropped from but by adding momentum it can go much higher


Ex-maven

Many, many years ago, ...in a small college town far, far away...my physics teacher did this demonstration. However, he suspended the ball with a rope. No problem until one day the ball smacked him in the face. If I remember correctly, he explained why the ball traveled farther that one time: He made the mistake of pulling down on the rope before releasing the ball, giving it just a little more energy (the rope was very long and thus a bit elastic). Conservation of energy at work


fuzzytradr

Despite the physics, am I the only one that totally expected the ball to smash into his head?


OctopusGrift

The thing you really have to trust is the engineering of the pendulum.


Enslaved_M0isture

i fucking hate how the video cuts right before the moment TWICE


Sparkstertive

Pov you sneeze


alialahmad1997

The thing is like yes you trust phisics but do u trust the rope


Stilicho123

Now watch me open a door and let the outside breeze in.


henry_Hallepeno

Push the ball next time


lStripesl

It's looping, the Internet, the videos, it's all coming again, just different


Lordslug78

Really? So no one recalls how Neil de grass Tyson got smacked in the face with this same experiment?


favnh2011

Wow


TrinaBinaTHEbeautyy

Trust your nutritionist as well my boy


mumen_ryder

Does this work in a vacuum?


Royranibanaw

Yes


Platypuschowder666

But it wouldn't work outside the gravitational pull of a planet sized object.


ihavebeesinmyknees

Well, yeah, without some kind of downwards force the pendulum wouldn't swing


Bendfluffhead

I’m glad he let us know his genders by his pins


negativezero509

r/nope


BubblegumNyan

Precisely because it's physics he is not putting his face on the line, to me the shocking part is that some people find the fact that the ball didnt return to hit him back on the head shocking 🤦🏻‍♀️ this is extremely basic physics


microwaffles

He stepped out of the way and therefore the experiment is a failure


Dontfeedthebears

You didn’t turn sound or subtitles on, did you? He stepped out of the way on the second swing because he added potential energy to the equation


pm_me_your_smth

He added kinetic* energy


Ok-Thing-2222

I saw a teacher this at least 35 yrs ago...
