Playing roblox with mark rober for 8 minutes 

“That’s how space works” whoops :)

i didn’t expect actually mark rober i thought he was playing a game based on his videos or something

Mark sounded so genuinely happy when he made it to mars

I love how Mark sounds like hes actually having genuine fun and full of authenticity

its been so long since he colabed with someone other than his brother, its nice to see him branching out again

mark rober + sketch = interstellar domination

sketch just drops the hardest mars edit

It always warms my heart seeing big creators like sketch shine light on the little guys

most unexpected youtuber collaboration I’ve ever seen

0:30 "markus Robert" I felt that sketch

mark rober is slowly making us all nasa engineers

fun fact: of course everyone wants to play with sketch for 8 days

sketch never fails to give me stage 57 ball cancer

Love the vid, keep up the good work and Can't wait for more collabs like this one. P . S Does Mark Rober have a gaming channel?

Who knew the most unexpected collaboration could've been this good.

LETS GOOOOOOOOOOO THE TWO GOATS HAVE FINALLY COLLABORATED

it's the man.. the myth... the legend! 𝗺𝗮𝗿𝗸𝘀 𝗿𝗼𝘃𝗯𝗲𝗿

Mark rober?the collaboration nobody asked for but is close

Mark Rober (science) * Sketch (unhinged chaos) = The end of reality and raining Doritos

"Cause that's how space works it's gonna-" *Asteroid hits sketch in the face*

The collab we didn't need, but it's good to have

OMG WHAT AN UNEXPECTED COLLAB

Lowkey thought Sketch was clickbaiting us but this is real- crazy.

This was a sick collab 🖤

What genius thought of pairing 2 of the worlds greatest minds together Give them a raise.

5:31 - 5:45 THE COMEDIC TIMING OF THAT ☠And the way Mark flew out the ship 😭

For a second there I thought he was going to play with Mark meaning that I thought it was Markiplier

You know its a really good day when sketch collabs with another youtuber

Mark is so sweet 😭🙏

8 minutes seems like a cool guy

My wow this is the best collab

*You have me inspired to start making vids.* Much love and major props to you Sketch! ❤

Just watching sketch and mark play together is so wholesome

i never knew i needed this collab 😅

Lol nice 0:24 “mark brober” makes sense

If you told me a day ago that mark Robert and sketch would do a Collab, I would call you crazy, so glad to see sketch making some new friends lol

The collab we all didn“t expect but was awesome

5:25 Because that's how space works- - - AAAAHHHH NO NO NO NO NO, WAIT WAIT WAIT WAIT WAIT!

The collab nobody asked for but needed

Wait did sketch put my game music 0:03

I love this video the collab was amazing

The Collab we thought we never needed but loved

This collab is so cool, both of these people are so funny and i love how its not awkward. you can tell there really having fun

4:27 MADE IT TO MARS WITH THAT MARS ROBER

The collab we never asked for but we got anyways

that curiosity rover edit at the end was 🔥🔥🔥🔥

bro this is the collab that i have never been waiting for but just found out that this is what i always needed

That intro aged well 💀

the collab we never knew we needed

i feel like mark robber would be like "wheres the science?"

This is the most weird yet satisfying colab we have gotten in years

6 years of being a fan never knew this would happen

Sketch never fails to make me brush my teeth

Sketch never fails to bring us joy

It’s hilarious that Mark is acting normal while sketch is acting like a doofus.

Nice for him to collab with smaller RU-vidrs like mark

Mark HAS to be the coolest dude you'll ever see.

The collab i never thought would happen

Surprised they didnt pull a gru and steal the moon

“Umm actually there are 2 seconds extra”🤓

I thought this was a joke collab… *i thought wrong this is amazing*

Yo sketch keep it up! Ur vids are so good! And ty for the good content 😊

Sketch is the only RU-vidr that I think won’t fall off. Because he’s still funny after so much time. Sketch is truly peak.

Who else just loves Sketch?

how does he always find the greatest outro music😭😭

How cool of skecth giving an shoutout to an youtuber with 54.5 subscribers☺️

and so then, the epic tale of every single youtuber playing with mark rober begins.

Sketch never fails to eat my organs 😊

I am watching this video 8 months after it cam out and it said 8 minutes

as soon as they got in sketch's rocket and it went left i lost it 💀💀

Knew this was coming since I saw you in the beta tester role. Amazing!

what a truly creative title

5:13 lol 😂😂😂

just finished his video and then i see this. it all comes full circle

Nice -Banana approved

the most unexpected collab that i am glad that happened

Sketch be having the most weird enjoyable videos

1:26 leaked

The reason Sketch is successful is because his music is authentic. He built a loyal fanbase on consistency, and not trying to sound like every artist. I pray one day my music can touch masses like Sketch. He’s my biggest inspiration!

sketch never fails to entertain our balls 😁

Marks avatar is the most unsettling and unhinged character ever

DAYYUMM..... LOOK AT THIS LEGENDARY COLLAB... THIS HAS TO BE THE BEST COLLAB RIGHT NOW
