The Scientific Smelly Challenge ft. AskKimberly

[@isoluniv_714z7]

"Omg we're so in love!" Awww. 😊

[@Daniel43453]

It's so cute how they chose each other's shirt.

[@HersheyBar1010]

ikr

[@fairycat23]

The adorbs killed me a little bit when they realized their favorite was each other's shirts.

[@Regene4239]

Haha, that's so cute that they chose one anothers!! There's probably scientific reasons why, but it's still cute af.

[@Naiadryade]

It's the most adorable thing!

[@db-cn4cq]

Regene McTornth The reason they picked each other's shirts is the reason they picked each other. They like each other's pheromones.

[@kakasedfg]

Regene McTornth it's call editing

[@karlmarquez283]

Dead. Cause of Death: Extreme adorableness because they chose each other's shirts. No relationship goals met or will be met on my side.

[@MelissaFlaquer]

I love how Greg chose Kim's shirt like a Bro's shirt, friend but not really attracted to it, and loved it... maybe because she has a similar genetic makeup to Mitch which makes the whole "they picked each other's shirt" thing even more cute

[@neiljones8611]

Also, you guys are too cute preferring each other's shirts!

[@CampeónPictures]

i love this channel because you combine science with fun. I wish you guys were my teachers!

[@sage2658]

Ikr

[@drewg.4779]

There's a difference between educational and informational. If they were your teachers they would probably do about the same thing as your teachers do now, they would have to do all the curriculum.

[@drewg.4779]

They wouldn't really be much more interesting, the videos they make here are informational, not educational. You need to do all the boring bits at school so you understand the cool bits.

[@crystalpinto1980]

The fact that they picked each other's shirt and at 6:58 They both fixed their hair!

[@Manujfb]

You guys should collab with superfruit. You even share a name

[@sage2658]

That would be amazing!

[@Bibysquid]

Gregg is so adorable he makes me smile so much!

[@sophienixon7973]

What? Two of my favourite youtubers are siblings... MIND BLOWN

[@hannah.b_765]

Even science ships them

[@hannah.b_765]

This makes me believe in true love again

[@Diajg3qp]

"Omg we're so in love!" Hahhaa XD awwhhh u guys are awesome.

[@XMusicRocksxxX]

The fact that they were so happy about choosing each other's shirts is honestly so cute ^-^

[@mayae743]

Jesus, this was so cute. "Oh my god, we're so in love!!!" AAHHHH!!!!! TO KAWAII!!!!!!!!!

[@bradleynoneofyourbizz5341]

Rosalie Fontaine I did flag it but please don't deny me the pleasure of telling the idiot off! It's my purpose in life!

[@joeypoltergeist1147]

Awwwww when you two realized you chose each others shirts I practically died from the cuteness!!

[@dikshachahal691]

[@onlyangel07]

[@evea.4358]

[@miathomas5383]

I absolutely loveeeeee this channel c:

[@natalia5189]

The ending was so lovely, seriously I feel so lonely.

[@kierancampire]

I'M SO EXCITED TO SEE THIS VIDEO FROM HOW EVERYONE IS TALKING ABOUT IT IN THE COMMENTS! :'3 But just a bit from the first few seconds, can cats be attracted to pheromones? Just because, I'm the one who feeds my cat, i play with her and hug her a lot, i let her out but not so often as others usually do it, my sister was the one who rescued her, i spent the first night with her, was the one to pick her up at and from the vets, spent that night with her, i got her used to going out doors by walking her, so physically it makes sense why she likes me, but even then, the first night my sister found her on the street and bought her home, the cat ran straight to me, and now still she is on/around me or my stuff as much as possible, i need to keep my shoes, and only my shoes in a box with a lid otherwise she suckles them to pieces, and recently she likes to stick her head in between my arm pit and like, rub her face on it, bite it, lick it, all weird things! XD So can animals be attracted to human ones? Cause it just seems weird how she is with my clothes/possessions and me from the start haha

[@hymenopteraisthebestorder]

Well there goes my heart

[@yabashe]

That was completely silly, but also cute and interesting :) Kim seems really sweet too, you're a lucky brother, Mitch!

[@yes1sir1no1sir]

Well that's given me the warm and fuzzies.

[@bizmullen9972]

I don't think this necessarily supports pheromone parties. They may have made an association between the scents that they smell when they are around each other and the joy they find in those times.

[@elliehaycock9228]

Otp goals

[@elliehaycock9228]

I love the amount they 'liked' each other's!!!!

[@Faith276]

THIS WAS TOO CUTE Y U DO DIS I'M FANGIRLING BECAUSE YOU TWO ARE JUST SO CUTE

[@briannau.4111]

Hey guys, idk if you'll read this but I loved your book, one of the most entertaining by far, and I don't read Lol. Im so hapoy my curiosity is killed sbout weird scientific topics.Good work, you should make another!!

[@annievalontine389]

I found this video a tiny bit boring but when they chose each others clothes I was in awe lol So cute

[@Ale-bm6xr]

This is adorable ♥️♥️

[@jptrainman]

You guys should do a video on cancer, I think that would be really interesting.

[@blondfashionista]

Love it!

[@lunablossom]

When Gregg said 'cheese sandwhich' i got a really strong taste in my mouth of cheese sandwhich, despite the fact I haven't eaten one for days. I was just wondering if this happened to anyone else.

[@bradleynoneofyourbizz5341]

joe charrot Yes. My first thought was that I don't have any cheese in the fridge!

[@lunablossom]

:D

[@100percentELF]

I didn't, but when I read this comment I did XD

[@brianific]

Haha this seemed set up just because I feel like Greg was super ready to pick that Herbal Essences one.

[@neiljones8611]

I am so attracted to the scent of some people. Weirdly, when I was younger, I could easily identify if someone had been in our house by the smell that lingered. It even spoiled a surprise visit from a boyfriend because I knew he'd been in our house.

[@gg1136]

How Romantic! By the power of science your love is true!

[@hyenaedits3460]

I heard that when murderers are about to murder someone, their sweat has a noticeably different scent. Also, if an animal is scared enough (humans included) you can smell its fear.

[@KoolKaur]

SOOOOOOOOOOO CUTE STOP IT

[@juliafreitas2905]

THEY ACTUALLY PICKED EACH OTHER IM LIKE AAAAAAAAAAAAA YALL RLY ARE MEANT TO BEEEEEEEE
