This Could End The World! 

Viks quick calculation then "Oh shit!" was the best part 🤣

Title: This could end the world Thumbnail: JJ smiling

"This could end the world!" JJ's face in the thumbnail: 😃

“ The whole of North America will be severely damaged and some parts entirely destroyed “ Harry: “ I rate that you know? “

God tweeting " Gonna shock the world" Will end the world

"This Could End The World!" JJ:😀

I love how they said “hiding a secret” as if most people don’t know about this already

Sidemen* gets scared about Yellowstone ending the world.* Vik: "elon musk come through and get us to mars" *Olympus Mons just chilling on Mars being the biggest volcano in the solar system*

Better late than never “Learning with the sidemen.” My favorite childhood show 😂

Sidemen: Intellectual video JJ:"struggling to sexualize the video"

This would definatly put Matt Hancock out of the news...

"World would be 10 degree cooler" Me as an Asian : Finallly some good fckin weather

Daily reminder JJ is the only one that can be a bully and a friend towards vik at the same time

I love how Tobi goes “NO WAY” every now and then when it’s quiet just to make sure we know they’re not bored too 😂😂😂

Props to this guy for almost saying "Taupo" correctly. He said it better then most Kiwis 😂.

vik saying move to mars, but little does he know that there is a much bigger vulcano there haha

I have a geography test on monday and my mum caught me watching this video and i panicked and said these are my teachers.looking forward to see you on parents evening :(

“This could end the world” , JJ casually smiling lol

Moments I loved: 2:25 - Vik realising we're screwed 5:30 - Vik calling out the fun but 9:40 - Vik realizing the fun bit

I just moved from London to colorado and I just cried i can’t stop singing that Ed sheeran song ‘ take me back to london’

RIP America 💀

To make things even scarier, we can’t even run away to Mars, as Olympus Mons is a volcano on Mars that is THREE TIMES LARGER than that of Mt. Everest, standing at 22 km above sea level.

the moment Vikk realizes that it adds up llooolll

"Everything is in a fragile balance so we should appreciate it" Wise words from Vikram

Let’s just be glad according to scientists an eruption isn’t due for a couple hundred thousand years

“The Temperature May Decrease by 10 Degrees” Me in My Arab Household with 50 Degrees Outside : “A Surprising Outcome , but a Welcome one “

Australia: They laughed at us, they made fun of us, now... now we'll be the ones laughing!

Vikk, Tobi and JJ is such a good combo for this channel

3:35 To put this into perspective: the state of Texas is almost 3x as large as the entire United Kingdom and over 5x as large as the country of England.

"Might cool by 10 Degrees" Himalayans: Oh no *Anyway*

As an American, we'd be absolutely screwed. Wildfires here in California where I live are already depleting us, if that eruption ever happened California would be dead.

2:32 Is it just me or has Tobi never laughed like this?

Canadians must make a stand, petition to remove the USA from North America

Ironic JJ is wearing a ZRK top when josh has a fear of death😂

This is the kinda video vikk gotta be in 🤣. Look at him all excited 😆

These are the best vids honestly imo, I don’t even bother with music video ones.

I was almost certain JJ was gonna make it weird with sexual innuendos.. genuinely surprised

Title: “this could end the world” JJ in the thumbnail:😁

My class & I just finished watching a BBC Historical-Fiction docu about this in school.

Sidemen worried about Yellowstone while in the UK. Me living in Idaho 😢

Sidemen again saving my life

Loving Tobi's new setup 🔥🪴🪴

I've been to Yellowstone before, and it was actually really sick!

“I could go for a hike Harry be happy” vik Makes sense now

Sidemen reacts, you don't only get entertained you also learn. Love sidemenreacts school

Surprised so many people don't realize that, at any point, the Earth could literally just decide 'fuck humanity' and we're all gone in a decade.

was a guy who worked for USGS that stated on video that once yellowstone starts to see earthquakes about magnitude 2 we should worry ..there has been mag 3s ..nobody can determine when it will pop

Always a great video when they react to real life lore One of the best geographic/history RU-vidr recommend you watch him

They should definitely react to one of LEMMINO's videos.

i remember learning about this in geography years ago

Did a biology project on the hotsprings in Yellowstone, Wyoming, super cool, gotta visit

Born and raised in Wyoming :) it's a gorgeous place and most grade schools make it a point to take all students there for science field trips and a good time in general

JJ gonna somehow casually make ending the world sexual

Remember guys God can come like a thief in the night when we least expect him

Bro no cap sidemen give you powers. I was playing rocket league while watching the vid and i scored a triple flip reset no stall when im diamond 2. Sidemen give you power

Vik got soo happy when he realized they wouldn’t be directly affected

'That was known as THE year without summer' London: hold my rain

They deffo need to react to the "History of the Entire World I Guess?" By BillWurtz

Nearly went to YellowStone last week. But ended up just doing the other National Parks, like Canyonlands, Zion, etc... All I can say is, it is even more beautiful in person.

We not gonna talk about how this was the first video where jj didn’t make a sexual joke?

the way he said it like “lake topo” 😭

2:24 DID KSI JUST DO QUICK MAFS? FASTER THAN VIKK?!

The end is a uniquely human construct that has grown out of our fear of death and our desire for personal comprehension. Since energy can never be created or destroyed. One could argue that the concept of an end is actually just a simplified observation of change. However, change is always happening. So couldn't we argue that the end is always happening? Should every moment be considered a funeral for the immediate past? If not, What dictates a change great enough to signify the end? My theory is that preparing for the end is a personal journey that never concludes and takes us to our end. So, when I say to prepare for the end. What I really mean is have a nice day!

I’ve spent some time working in Yellowstone, beautiful country intimidating country that changed my life

6:54 Me: staring at JJ waiting for a inappropriate reaction

I love how the United States' debt is still more than that. 😂

I love it when you guys don’t show clips of the video at the beginning. Makes the video seem less clickbaity

Temperatures in South Africa barely ever go below 15°C, even in winter. So the drop in temperature wouldn't affect anyone with multiple blankets at their home. Which is basically everyone....

what’s the vid that harry tells them to “take a hike” that they keep referring to?

HAHAHHAHA JJ IS JUST 30 SECONDS BEHIND EVERYONE ELES IN EVERYTHING HES SO FUNNY HAAAHHAHAHA

Toby with his new setup 🔥

Awww jj supporting josh by wearing the zrk shirt ❤️

They should react to : Why this room is the most dangerous place in the world

New sidemen video “We explore yellow stone national park”

Yellowstone: Volcano type: supervolcanoe (Caldera) Eruption: 25 Million years ago (MYA) VEI: 8

This is best reacting trio 🔥

It’d be an apocalypse, everyone fighting for food, fighting for refuge, etc etc

They be consistent every day

This is the tamest JJ has ever been in a sidemen reacts 😂💀

"lake towpoe" I live in New Zealand and that just pissed me off 🤣.

wait vikk Mars has the biggest volcano in the entire solar system, so gud luck going there

It’s a lovely day to be on the east coast. At least I won’t be immediately dead in Philly😭

Bro I'm in Australia. I'm pretty much good over here. Lowering 10 degrees would be nice. Over here in winter, the lowest it gets to is 5-10 degrees. In summer, it gets up to 40. We're chilllll. Unlucky America...

your smashing this yt this year boys {even though harry dsnt upload lol} jj no1 on Sunday to top it all off ???? I THINK SO !!!! LOVE YOU GUYS YOU DESERVE EVERY SUCCESS XXXXX

The video title scared me for second not gonna lie, great video.

10 degrees cooler? Say no more we Australians are keen 🤞🏽

Quietest Sidemen reacts video. You’re all just in shock innit 😂

Hearing that it won't erupt for 10,000 years feels soooo good. And also heading it's only in America as I'm English

2:36 Ahhh sheeeett

We want more intellectual sidemen reacts !!!

1:15 hiking reference makes sense now lol

11:53 Everyone living around the Equator: 😁😁😁😁😁

Haven’t even watched the video yet and I already know JJ is going to say something sus

"It could cool the world by 10 degrees!!" Me who lives in kuwait: "Finally, peace!"

Knowledge having trouble understanding 🤣🤣🤣

10:57 It's Mt. Pinatubo. Joseph made an error there.

Yellowstone blows up... JJ: Smiling

Ya know what’s scary is that I’ve gotten pray RNGesus drops rarer than this before. Puts things in perspective…..

The perfect set up for eruption jokes and JJ to make it weird. I'm more shocked it didn't happen!

Y’all should react to extreme cheapskates, I’d rlly like to see u guys react to them 😂
