“This looks familiar”😂😂

Can’t believe I watched people taste different waters for 11 minutes 😂😂

I'd never thought i'd find two people tasting water interesting and fun until I watched this video, but since it's Mark and Zoe I should've known it

When zoe said they were going a water testing challenge during her video I thought it was a joke because of how much water mark drinks...... it wasn’t..... I’m glad.

I’m happy I’m not the only one who thinks that water tastes differently

1:55 that Zayn reference got me

This. Is hilarious!!! I love how Zoe is just like, I mean, whatever, but Mark is behaving like a pro, who knows exactly what he’s doing.

Mark: "I feel deflated" - Zoe: "I feel inflated" 😂😂

Mark “do you know what this tastes like” zoella “water!” Oh my god I love these two so much! 😂

try testing coca cola, diet coke, Pepsi, Pepsi diet, own brand cola etc.

Where was the tap water vs water machine with ice ??

Haha it wouldn't matter what you two were testing, when you're together I'm always laughing! 😊💛

I loved it when Mark said "Ooh thats a nice one" I just burst out laughing, I love how he can actually tell the difference. Literally love them both ! ♡

I've been so excited for this video yayyyy! Zoe and Mark videos are the best by far ekkk☺️❤️so much love for you both xxxx

I can hardly taste the difference between tap and filtered water this would be a mess for me 😅

You could try guessing the scents of perfume and cologne Eg Calvin Klein or Zoellas or others

Just came from watching Zoe and mark to mark and Zoe

This video was great u and zoe are like Bert and Ernie, yous go so well together 😂 my fav thing sitting down with a cup of tea watching my 2 fav KZfaqrs 😘

Aww Mark seems so upset

5 years later and I'm still watching people try different waters

Mark and Zoe ARE LITERALLY BFF GOALS I SMILE ALLLL THE TIME WATCHING THEM LOVE YOU GUYS SO MUCH 💖💖💖💖💖💖✨✨✨✨

Someone should’ve put a cheeky little bit of tango iceblast from their machine and added abit into the water and see their reaction it would’ve been hilarious 🤣

Did anyone else notice that mark wrote mike on his paper for his name

I'm from Buxton!! the water factory's just up the road from me lol, reppin'! 😂 love the video!

Hi there Mark who new tasting water could make a funny video only u and Zoe get away with this lol 😂. XxxX

"voss happenin man" noice.. ah the memories

Do a series where the 2 of you test out different foods and drinks like this!! It would be amazinggggg😍💓💓love you bothhhh!!!❤️🌹

Thankyou for this video, we had to put my cat down two days ago, and im kinda coping but the house feels empty without him😔 we had him from when i was 3-18 years old so hes been through it all with me. Atleast he isnt in pain anymore.

Possibly the weirdest but amazing videos ive seen of you and Zoo 😂😂😂😂❤️❤️❤️ i love ittttt

Water tasting...yeah ok 😂❤️

“Do you know what that tastes like?” “Water.” 😂😂😂😂😂

Well, I never thought it would be entertaining or interesting to watch people drinking water. But then again it is you two.

I love how serious Mark is taking this!!!

Mark was having so much fun analyzing the waters thoroughly😂😂❤️

“This looks familiar.” Too funny, Mark!!! Love you guys. 😃

You 2 are so fun to watch whenever you are together no matter what you are doing.

Loved this. Subscribe to both these people because they are awesome, amazing and so pure!

You guys film this in May? Because you are wearing the same clothes as the reacting to our funny moments video

Even though it’s 11 minutes of people drinking water, I thoroughly enjoyed this experience x 😂😂😂

"Do you know what that tastes like?" "Water?" I love these two way too much😂

Love you and Zoe doing challenge videos, it was so good please do more of them

Omg these two are the only people who could make this video funny and entertaining 😂❤️❤️

Mark if you see this by crazy coincidence, after doing this challenge did it make you want to switch to a different brand of water? Also I would love to see you try and guess the different flavors of Oreos including some of the flavors from here in America because we have some crazy ones.

HELL YEAH I just binged watched all your other collabs with Zoe and then there is a new one yeeey! I'm so happy and excited to watch this :3 Greetings from Germany ♥

only on youtube and with zoe and mark do you find water testing that is entertaining xx love u both

I love how Mark wrote Mike on his name sheet 😂 Also, you could make an entire funny moments compilation from this one video alone 😂😂

Zoe or Marks video first both amazing and so funny 😂 💕💕

Funny video, really hope you recycle the plastic after!

Honestly I just love yours and Zoe’s friendship. It’s so witty, crazy and unique and you’s two always brighten up my day. Thank you for the comment the other day too it made me so so happy!

Absolutely love you two! You’re the definition of friendship. Constantly making me laugh so cant imagine how hard you guys laugh on a daily basis!

Please do more like these! So funny!😂😂😂

To be so privileged that you guess the brands of water..

Zoe “I mean, I’m just gonna guess like I did in all of them” *me every time I take a test*

“This looks familiar” I died 😂😭

Yay!!!!! I’ve been waiting for this ever ever. Since you mentioned it!!!

4:06 they both look so angry 😂😂

This is why these two are the best people on KZfaq 😂

Every single video you guys film together is just absolutely hilarious! I love you both SO much.

Those sheets remind me of homework in primary school!

Only you guys can make drinking clear liquids entertaining 😂

I can’t believe I just cracked up multiple times watching Zoe and Mark drink water!!! 😂😂😂

I honestly get so excited when I see a Mark and Zoe video!

Did marks paper say mike?😂

Love this idea as water is pretty much all I drink and have always wanted to do this myself to see how well I would do 💕💕 Such a funny video 😊😊

Maybe the water challenge should have been before the pizza 🍕 Mark you are amazing. Every Mark needs a Zoe xxx
