Hilarious QI Moment - May Contain Nuts!

Brazil nuts are revealed to have a rather unusual quality.
Also featuring a rare example of Fry using his "crass" voice "May contain NUTS!"
Taken from QI XL series I episode 3 "Imbroglio"

[@Gyrbae]

The brazil nut also contain high levels of radium. The radium in Brazil nuts is a mix of Ra-226 and Ra-228, and the high concentration of radium in Brazil nuts is due to elevated levels of the uranium and/or thorium series in the soil in which the tree grows. Also it has the highest fat level than any other nut. Seriously, it's the freakiest nut ever.

[@djmoch1001]

"MAY! CONTAIN! NUTS!" God bless Stephen Fry. He's a global treasure.

[@kida4313]

MAY CONTAIN NUTS such an underrated moment from Stephen.

[@Mochrie99]

I don't think I'll ever get tired of hearing Stephen go "May contain NUTS!"

[@viktor187]

At four minutes flat I wanted to scream at the cellphone: "YOU'RE TALKING ABOUT FUCKIN NUTS" 😂

[@sofrknasm]

And from this day on I will always on the first date ask if she is allergic to nuts.

[@RKBock]

"Well, if I even see yours, one of us will need to see a doctor!"

[@anna-mariagio843]

a good murder plot! haha

[@Dunam]

I think the refference to house made him associate hugh laurie and as a result, his sketch comedy history. I think that's why he did something he doesn't usually "may contain nutes"

[@AymanB]

Psychoanalysis-much? :D But I like that.

[@sapphire962]

Stephen: "What do you think is inside this?" *shakes* Me: Kinder egg surprise by the sounds of it...

[@123121s1]

the physical qualities like shape, density and mass of the brazil nut relative to the other contents of the bag is what causes them to rise to the top i would say

[@OnezumiDaisuke]

I SO want to see this worked into an episode of Sherlock now. -Oh, course it was an accident. She obviously went into anaphalactic shock; his clothes are covered with salt and pieces of skin from a cheap brand of mixed nuts; and he is clearly too ignorant to know that the allergic quality of Brazil Nuts can be transferred through sexual activity. I'd die laughing. :D

[@FlyingLlamaa]

That's nuts!

[@GuitarBlues3]

My god, I was almost crying at the end!

[@Son0fHobs]

Holy smokes. Thanks for queuing me in! PBS had a great article talking about this, and a few others, like the nuts could stay dormant for years, fall from 200 feet high at 50mpg while weighing 5lbs. A single tree can product 250lbs of nuts a year!

[@tbandmint]

Stephen Fry: Britain's Foremost Man of Letters Also Stephen Fry: "MAY CONTAIN NUTS"

[@maliivan1993]

Apparently my professor of Mechanical process engineering has secret knowledge nobody knows about because she explained how this happens and even used Brazil nuts in a bag with smaller ones as her example.

[@9_in_the_afternoon]

Brilliant, do you remember how she explained it?

[@maliivan1993]

Tori Lee The simplified version is that if a bag of objects of varying sizes is shaken enough the smaller objects will fall through the cracks between the bigger ones.Since the smaller ones will tend to go towards the bottom they'll inadvertently push the bigger objects up.My explanation is probably far from perfect but that's the gist of it as far as i can remember.

[@RKBock]

@@maliivan1993 why would they push the bigger objects up?! the premise is, that the only force acting is gravity and that small objects can fill small cracks. so why the hell would the bigger objects suddenly rise?!

[@heidigough8585]

Feeling irritatingly pedantic but the Quality Street purple ones may be brazil nut shaped but they contain hazelnuts.

[@kevinroche3334]

they used to be brazils, until the price went up so much they swapped nuts - I cried for weeks

[@iwakuraSanta]

THAT WAS QUITE INFORMATIVE ,I LOVE THEM PURPLE ONES

[@MatthewPlato91]

Nuts, seeds and berries, going to a supermarket and looking down the shelves must be a nightmare for a observant botanist!

[@chompette_]

when he shook it i thought it was the shittest kinder egg ever

[@lavie9444]

lmao, that was my first thought, too :D

[@TheOriginalBoman]

It's funny that Stephen says nobody knows, but I remember an episode of How 2 that explained how this phenomenon occurs using a marble stuck inside a bottle of rice. When the container is shook, the smaller items move allowing the larger items to rise and, because the smaller items compact, the larger item settles on top of the smaller items.

[@Arkuzian]

i know i know, 10 years later, but the whole idea was that it doesn't seem to be consistent and people still have no idea why it happens, we just know it happens with a few exceptions

[@lyadmilo]

penicillin is also an STI allergy. If you're on penicillin and your partner is allergic, be careful. I have to ask for amoxicillin because even kissing could hurt my husband.

[@fifi298]

Amoxicillin is penicillin.

[@MrFredd38]

I won't kiss your husband

[@MsTeacher17]

I am allergic to penicillin and I have never received an allergic reaction from my husband. That sounds like an old wive’s’ tale. I think our doctor would have warned us.

[@OlOleander]

Iiiiiiiii would recommend looking for another alternative antibiotic, because those two are essentially the same allergy.

[@mandelstuvning]

hhahahha

[@ezelouie]

Not sure if its the same thing but when you "rub in" butter to flour if you're making scones, if you shake the bowl you are using, any large pieces of butter that are not incorporated will rise to the top.

[@paulo1ftw]

Is the brazil-nut-top malarkey not some form of Brownian motion?

[@godofcrap42]

Yes, and that's why it's 'Quite Interesting' XD

[@junbh2]

This clip shows perfectly the problems with trying to protect a particular species -- everything is so incredibly intertwined that you need to protect the whole ecosystem, otherwise it all falls apart like dominoes.

[@Otakuonfire]

It always seemed logical to me, when products are transport, your sift your hand through a bag or otherwise. smaller bits of nut are obviously going to fill in the 'gaps' made by the movement of the contents. The same way flour is put through a siv, the same way crumbs are always at the bottom of the bag of chips, etc..

[@thenerscylla2388]

Surely the reason they rise to the top is that there less dense and therefore "float" to the top like wood in marcoscopic water molecules

[@BlogBitch]

So now I know why they are so expensive... fair enough.

[@morthasa]

Sorry about that: I did not mean for it to be a fake. When I saw the final quality I saw it was not actually HD, but thought it was decent and couldn't be bothered to try reuploading it just to remove the HD tag.

[@1701enter]

Its all about the angle of repose

[@CadetsPwnTheDCI]

Where in the US is that!? I've never heard that before!

[@miscreant239]

It's actually well explained, known as the Brazil Nut effect.

[@CouchKuma]

"Well, that's a good murder plot, now isn't it?"

[@dumbo800]

There kind of was an episode of House on this.

[@Bridonia]

"May contain nuts" hahahaha

[@marycanary86]

that actually is a pretty clever murder plot....

[@eddieburrelli]

Oh, how I LOVE QI!

[@eddieburrelli]

I really, really do!

[@TheEditingShop]

2:17 - GIF IT GIF IT!

[@toolworks]

There now exists a theory for why the larger solids rise to the top in a mixture.

[@Stormwern]

Probably slipperyness. The slipperier they are the more likely they are to move around, and they are more likely to move upwards where it's less dense.

[@Gouldsonuk]

we must alert the proper authorities! the mystery has been solved haha

[@victorlaszlo1111]

Some one actually earned a PhD by experimenting with different sized ball bearings and a "shake table". As gaps form below the various objects, the smaller objects can fall into those holes more easily - so the smaller objects drift toward the bottom, which moves the larger ones progrssively toward the top. And size is much more important than weight - which would seem to set up at least a few punch lines.

[@andreasegde]

'Cos they pack the Brazil nuts last. Doh!

[@123121s1]

well it is that simple, that's kinda the point. they are looking for something more specific than just "physics" because we already know that everything physical is affected by physics, so it doesn't really need to be said

[@thany3]

What a bunch of nutters 😄

[@DrBilton]

Nutception.

[@ArchitectCobra]

For Science!

[@sporkincarnate]

@MrZasbot Stephen Fry and the Joker. I'm not sure what conclusion I should draw from that. ^^

[@Gouldsonuk]

first off, my name isn't goldsnon lol Nicely done though, good knowledge.

[@LolixLP]

So nuts may contain nuts xD

[@Geebsee]

Yep, Sixty Symbols (check channel on KZbin) also did a video on this where they were essentially saying the same thing. QI actually get things wrong a lot of the time, but of course it's hysterical regardless.

[@thesubhumancomedy]

Bananas, what are they, herbs, fruit, or berries?

[@joekewl789]

@Goldsnonuk and @ 12312s1: They actually pretty much have figured it out. I hate to contradict the QI elves here but the "Brazil Nut Effect" the 4 other particle segregation mechanisms that account for 80% of industrial segregation were identified by Kerry Johanson in the early 80's and quantified by his son (of the same name) in the past decade. (I had the pleasure studying under the younger Dr. Johanson for 5 years.)

[@marty9376]

Death by NUTS

[@handsomebrick]

Likewise for me with buffalo wings.

[@XoxBloodRainxoX]

For science! I think the scientists working on trying to figure out why brazil nuts rise to the top need to start thinking with portals.

[@Wickey132]

Not sure HD is of my worries with this..

[@10babiscar]

what's crass voice?

[@waynefarrellvoiceovers]

Ladies and Gentlemen...Sean Lock.

[@joebleasdale5557]

John Bishop at 1:42 was me when I heard about the sexually-transmitted nuts

[@jgw8603]

Serious question, would that be man slaughter?

[@shampoo1991]

Wow the more I think about the mixed nuts the more I think he's right about the alphabetical theory

[@CloudysGuitarChannel]

2:17 for may contain nuts!

[@gt46c]

Lets do this!

[@johnkelly3549]

God bless big Sean Lock

[@latewizard301]

*Nut* allergy...

[@franzfanz]

FOR SCIENCE!

[@Gyrbae]

If you're wearing a condom while.. doing it, you (and your friends) should be alright. If you don't, shame on you. It's dangerous to roam unprotected.

[@falloutghoul1]

Why do Brasil nuts raise to the top? I'm sure it's the same reason why those bread chips in Gardettos raise to the top.

[@theeditor8776]

Could it be because the Brazil nuts have a larger volume they are less dense and rise to the top??

[@iwanabana]

nah. simply because there are more ways for the smaller ones to drop and fill the cracks, resulting in the larger nuts to "float" on top all the smaller ones

[@martonk]

Yeah it was explained by sixty symbols at the University of Nottingham

[@SkwerlBergamot]

fuck, i take brazil nuts every day as a supplement, ima have to ask people i sleep with whether or not they're allergic to nuts

[@lottsofrandom8605]

Hahaha weird thing is I am actually only allergic to brazil nuts, all other types of nuts im ok with hehe.

[@manulito2]

@ElzoSmid1 interesting. 5 points to you ;)

[@MostAwsomeChannel]

lol

[@A_Salted_Fishe]

TIL why the slang term "nut" is a thing

[@VGMGarden]

''hahaha they've been known kill people.''

[@Mullahgrrl]

So if it is alphabetical order then we can save the earthquake victims by naming them all aaron or some such.

[@zibafu]

alphabetical order... scientists everywhere have just realized they overthink things immensily

[@13someguy13]

ummm... It isn't an unknown effect /watch?v=c3p3VMNpWGw In fact they call it the "Brazil nut effect"

[@Gouldsonuk]

A lovely idea but I think if it was so simple they would have figured it out. I mean you've spent 2 minutes watching a video and think you have figured out what research scientists haven't :P unlikely.

[@Degenerate_Gen]

found some cool information relating to why they cant be cultivated too "It turns out that Brazil nut flowers require a certain species of bee for pollination. The bees in turn require a certain species of orchid to survive. Male bees must acquire the fragrance of this particular orchid in order to attract female bees. If the forest is damaged by clearcutting, the orchids disappear, along with the bees and the Brazil nuts."

[@NwahWAttitude]

You can change the name of the video without uploading. Though I'm sure you don't care at this point.

[@antcommander1367]

Pls, dont try this at home. It sent me to ER, just to try that with my gf.

[@sebisam]

@thespikescheme ...every single one of them was having a laugh? Really? That's your best explanation?

[@jamescoleridge727]

it's not a firkin nut

[@thatdutchguy2882]

Please fire that dwarf that tries to pass herself off as "a Dane" and bring back Stephen Fry.

[@awkwardsean5141]

Look at that scousers teeth.

[@Truthiness231]

"Hilarious QI..." is a little redundant, isn't it?

[@awkwardsean5141]

Inseminate, lol.

[@SierraSierraFoxtrot]

Fake HD, nice.

[@mrwhippy101]

Who fucking cares you can still see clearly

[@DJPsyq]

Why is the audience always ill? So much coughing every damn episode.
