This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Ja***:

5:22

Who the hell screams ”gonnorhea” when they hurt themselves

MU********:

0:22 smart idea next to a tree and 2020

MP**********:

5:21 did he say “gonorrhea.”

Th******************:

0:34

Mark: "...so either Kevin has some superpowers..."
Kevin: nods

Ih********:

2:58 . Now we all now how corona really started

Kl******:

2:53 I just made a gif out of that.

Te******:

4:12
Why am i getting How To Basic vibes?

Si*******:

Did you say dairya when you got hurt! 5:23

Ru*************:

3:15 Kevin its big brain time

Mi*******:

2:58 anyone else whatching this in 2020 (corona)

Da************:

Mark Rober: has a corona beer in his hand

intense breathing

Sa*********:

I LOOOOOVE ready player one! it is one of my favorite books and movies

Br********:

This video taught me more than my 12 years at school.

Se************:

“You should set those on fire.”

-Kevin always

15*******************:

His craziness made him as famous as he is now...

Lx**:

THEY DID IT!!!!they broke the bottle n the corona virus exited n escaped omg!!

Ke****:

0:00

Those trees behind him looked like wings ._.

Re*************:

pov: you are here after watching physicsgirl 's video on Cavitation.

Kh************:

That book seemed
Interesting.. You're actually making me debate if I should get the audible trial or not..

Ni*************:

Anyone seeing this after ready player one released and after two years

Ar**********:

Who wants to see more flaming snowballs

Ma***:

5:23 I'm not convinced Mark didn't say "Gonorrhea" in a pained voice

Fr********:

did he say gonorrhea when he hit his hand on the bottle xD 5:21

Se*******:

Conspiracy theory: they knew! they used Corona Beer Bottles!

Ja*********:

Funny how he uses a corona bottle for the water

Ma*****:

the first bottle they busted was a bottle of corona well, we got a lot coming, I can feel it

De***********:

I love that YouTube brought this back to me lol

Fq*********:

I wish he was my science teacher because he would be so fun

El****:

BEST science channel on YouTube, I wish he would post more often

Ti***********:

05:24
That gave me the greatest nostalgia feeling I've ever had :3 So unexpected I wasn't prepared :o

Ju***:

SET IT ON FIRE
-Kevin (The Backyard Scientist) 2016

Re*******:

I love how he’s talking about ready player one before the movie came out

Re***:

5. Don’t chicken out:
Shows mark hitting his hand and then mumbling ‘gonorrhoea!’.



Nice

La*******:

"I'm pretty bored today so I'm gonna smash bottles."

fu******:

Mark Rober and the Backyard Scientist getting a preemptive strike on Corona, before Corona was a thing.

Ye**:

Haha..ThE BoTtlE sAiD cOrONA SHUT UP WE KNOW THERE IS A GLOBAL PANDEMIC

Ka********:

Me use this to impress my friends and failing to brake the bottom of the bottle

Ca******************:

Physics girl dove deeper into these theme in her recent video! It’s an awesome video!

Da******:

This channel gives me A+ at my science and chemistry tests than My teachers vids XD

Ch****:

From a fluid dynamics perspective:
It seems to me that hitting the top of the bottle sends a shockwave through the water. Shockwaves have extremely low pressure at the front of the shock and extremely high pressure at the back of the shock. When the front of the wave reaches the bottom of the bottle, that low pressure zone generated by the shockwave induces cavitation (the little pocket of air you see at the bottom of the bottle). The water cant hold onto the air bubbles that are already dissolved in it in this low pressure zone, similar to why boiling water is much easier at the top of a mountain; the air pressure is less. When the energy of the shockwave dissipates, this air bubble (cavitation) collapses and dissolves back into the water...very, very, violently. Often times at supersonic speeds. The force of that air bubble collapsing at supersonic speeds (which brings the water crashing down onto the bottom of the bottle), is what breaks the bottle, in my opinion. Perhaps Schlieren imaging could confirm this.

It would follow that the CO2 bubbles in carbonation interrupt this shock wave from passing through the liquid, and keep the wave from reaching the bottom with enough energy to induce cavitation. The low pressure zone generated by the shockwave would cause the CO2 bubbles to escape from the liquid, causing the foaming in the beer you see

This phenomenon is very similar to the cavitation seen in boat propellers. The propeller spins through the water, generating a low pressure zone behind the blades of the propeller, and when this pressure is low enough, the water can no longer keep those air molecules dissolved, and they are released into the water, generating the air bubble you see behind the propeller. When the energy from the propeller dissipates, these air bubbles collapse at supersonic speeds, dissolving the air back into the water, but at the same time gouging a chunk of metal out of the propeller.
