Can you drink Heavy Water?

[therealjammit]

Will D2O ice cubes float or sink in liquid H2O (hidden icebergs)?

[MegaSkills9]

@therealjammit

They sink. They are more dense. (I am sure of it. - I saw it done.)

[xxe1337forcexx]

@MegaSkills9 The density of the water decreases as it turns into a lattice. Compare the density of d2o ice and water.

[Zolbat]

I'd drink it! chemically it is pretty much the same as normal water, so I doubt that it would severely differ the body's way to work

[manmanguy]

You might be dead, brilliant.

[MegaSkills9]

If D2O is heavy water than it's seems logical that there should also be VERY heavy water made from Tritium. (The other isotope) Is there is such a thing as T2O ? (Yes I realize that Tritium is radioactive) If the much heavier isotope of Hydrogen (Tritium) does in fact form very heavy water...then what is the ratio of the amount T2O in a glass or gallon of regular tap water? (I am aware that about 1 in 6000 water molecules are actually D2O) What about T2O?

[YooEssBee1]

Two atoms are walking down the street one says "oh no i lost an electron" the other says "are you sure." "Yeah im positive."

[Snyltebiter]

@YooEssBee1

I told your joke in class today. Now everyone likes me. Thank you, thank you very much.

[YooEssBee1]

@Snyltebiter your welcome

[greekfitercod4ever]

@Snyltebiter you must be english, right?

[greekfitercod4ever]

@Snyltebiter you must be english, right?

[Tmaker197812]

Hmmm... standard enthalpy of formation D2O = 294.6 and for H2O = 285.8 / 241.8. We need more info about chemical properties of isotopes of the same element. Tests for D2O have been made inaccurately OR! planetary model is not quite correct.

[nybotheveg]

is it me or is the proffesor kinda shaking in the end D:

[sk8er4ever0101]

@nybotheveg I think i see signs of Parkinsons or soemthing D:

[zurechtweiser]

@sk8er4ever0101 Heavily so. The big elephant in the room actually.

[sk8er4ever0101]

@zurechtweiser :( :( :(

[Tmaker197812]

D bonds stronger than H bonds - I think he is wrong here. Both isotopes have identical chemical properities. Additional neutron do not affect on chemical properties of an istope only electron orbitals affect. H goes first during electrolysis because it is lighter than D.

[DasMilCLP]

@Tmaker197812 guy, he's a mad scientist xD he'll know what he says

[sgonged]

I bet he has a lot of dandruff.

[MetalPower86]

i like this scientist,  and his hair

[leondro97]

eintein reborn

[svagert]

woho, i'm norwegian! :D

[RHVids100]

just make a new video with the exact same title, but edit this one first, and just put a simple yes or no, question answered.

[MrSuperaman]

some one electrolyted his hair......:xD instead of water

[SirBrodzik832]

6:14 [...] Katz XD

[Raafay23]

he's saying D2O not "duderome"..fail

[AlphaKiloFive]

Maintaining the perfect stereotype of the extravagant scientist is one of the things that hook up young brains to the wonders of Science, which ever branch it might be.

I enjoy your videos and will continue learning the periodic table by heart !

[kght222]

well hell, if your going to drink some really expensive whisky, you might as well wash it down with some really expensive water, the price would be similar per oz.

[kght222]

@kght222 and no i am not advocating drinking a bunch of d20, but i feel quite safe in saying drinking a glass of d20 wont hurt you as long as it doesn't have any nasty impurities, and preferably if it has some tasty mineral impurities.

[tarthur]

Given the uncertainty of deuterium's toxicity, I think I would follow the Sigma label and wear gloves when picking up "heavy" ice cubes.

[ralbiruni]

This guy is a genius. I like his hair, I like his tie! Seriously, D2O is not dangerous, but as the main impurity is TOD, radio active, it is better not to do!

Don't forget it near uranium bomb exploding, too!

[apeek7]

Want to have some fun.... Make D2O ice cubes. They will sink in regular water AND I believe the D2O ice melts at a higher temperature than H2O so the D2O ice cubes, at the right temperature could sit at the bottom of a H2O filled beaker...

[ViolentReality]

u mad bro

[2000masquerade]

I swear to god I fucking laugh my head off evertime I see that dude wuth the afro

[Haruto1988]

its pronounced DeuterIUM ... not Duderome !

[pug6666]

So could I drink one glass of D20 and not feel it's effects?

[Phibins]

this is the best channel in all the internets.

[zillionz]

I'd murder a nice cup of tae, even if it's made with D2O

[UltraDrago2000]

So if you drink say 20% d2o you would pee less and dehydrate slower? COOL

[transformaconband]

@UltraDrago2000 But in return it slows down and even stops cell division which is necessary for our bodies to function.

[sonofmoe]

I love how the guy who fed D2O to dogs is named Katz.

[GumbieVirus]

You know i remeber  playing that mission in one of the Medal of Honor games, the raid on the power station.

[jounynFM]

I love this old guy, he is a true boss among men.

[BuickDoc]

Can you drink sulphuric acid? Yes. Can you drink sewage? Yes. Should you????

[rowanvidler]

Earths water has about 155ppm of deuterium atoms on average. so when your drinking heavy water it is a slightly higher concentration

[Aidokinn]

such a stereotypical scientist :P

[meagain2222]

No its not radioactive or corrosive.

[Leopoldo888]

Heavy water makes you fat?

[xxdevoidzxx]

professor, you do chemistry a lot, has your hair ever caught fire? xD

[FrogsGames]

His hair defies gravity.

[wazscience]

@FrogsGames more like it defies physics

[overclockedamd123]

these videos are like nerd porn for me....sigh. cant get enough of cool fact to use on random people

[halosux4life]

hehehe i work on vehicles that transport the shit.... i have an abnormally high amount of radiation in my body

[salerio61]

@halosux4life nonsense, it's not radioactive

[limefrog77]

"I just had my dog deutered" LOL

[SirSecrets]

Are there any other isotopes of elements we normally eat that can affect us differently?

[ASSNEWSOFFICIALCH]

Can you drink T2O? >:3

[Aviatorsmith]

@ASSNEWSOFFICIALCH No. It is not only radioactive, it is also corrosive.

[Aviatorsmith]

@ASSNEWSOFFICIALCH Although there are trace amounts of T2O naturally present in our body.

[killeroftheshadows96]

@Aviatorsmith *d2o

[KodierungHerz]

I love how the idea of tasting it stayed in my head until the very last phrase...

[AzfarulGiantz]

Can you see the dislike bar? me neither !!

[Greywolf831]

I'm thirsty



[Jakobus999]

he looks like a mad scientist :D awesome

[picaticatara]

i want to shave that dirty guys head

[YouHolli]

His Parkinson is getting worse :(

[omgthisiscrazy1]

scarey hair.

[kragle2008]

haha... He's vibrating! 4:10

[Probablyacowtbh]

@kragle2008 And?

[kragle2008]

@Probablyacowtbh Nothing..... Sigh



[D34Df007]

I thought Einstein had passed away... you sir, are stylin!

[ericsbuds]

Oh Professor, how I wish more people were like you.

[KatiushaVN4]

Einsteins wannabe

[JSprayaEntertainment]

ILL TRY IT ... Where do i sign up ?

and the last thing i want , is to be thought of as a nuke maker because i'm seeking D20 to Drink !

[gettingahandle]

Chemical exposure has frizzed his hair

[D34Df007]

@gettingahandle most likely yes. unstable elements like that will react with just about anything that has the right amount of electrons.

[patrickwellerwrites]

will the the same reaction happen like when you put sodium or lithium or pottasium in water happen with D2O?

[mikecook6266]

his hair must be like that through all the head scratching .....

[martinrd13]

my boyfriend's hair is SO sexy...

[dithy092388]

maybe the scientist's hair is like that because of too much thinking...

[YoMamaWearzArmyBootz]

@dithy092388 ahahahaha....^^

[rb21122b]

Why do all scientist's hair look like that?

[dongimin2]

@rb21122b its a gimmick

[TEHCHOSENONE866]

whats up with this youtube license (Shh! - Internal Dogfood)

[nuzod]

i wank to his videos

[gigantibyte]

What would anyone find objectionable about this video to give it the thumbs down? 

[imantisocial]

why hasnt anyone tried it on rats.

maybe ageing would stop.

[looksintolasers]

Nobody at the university volunteered to taste a drop or two and answer this question with an experiment??? I mean, if regular water is 1/7000 parts D2O, shouldn't our biology have natural defenses in place?

[qritique]

@looksintolasers

I would taste it. I think I might.

[Renee31199]

Why are you trying to look like albert einsten???? plz dont be him, youll look like a fool

[Stevelord666]

@Renee31199

You look like the fool.

[de0509]

haha rich dog. hey i hv a question. because deuterium is twice dense than hydrogen(coz they are gas they have the same mol per volume) can we like suspend one large tank of hydrogen and taking only the gas at the bottom. or is the diffusion rate just make this idea wont work... im just a student so sorry if this idea sucks

[drewnickel]

@de0509 it's possible but would be very difficult, as gases that tend to rise, also tend to mix. the light hydrogen will rise, and once it hits the top of the container the deuterium will rise and mix, eventually it would settle, but it'd be more ideal when it's in liquid form.

[lynkynpark86]

Nice!

[nzSkitzo]

View 55,000!!!

[Letspreach]

I love this guy. But when you mess around in long coats, mixing chemicals, it does have a side-affect. Hence the hair.

[sporestruck09]

Ladies and gentlemen, put your hands together for England's own Brittstein!

[akaAlexthekid]

Is it a requirement to have such awesome hair when you become a scientist?

[ApolloWasReal]

I wonder how hard it would be to make a small amount of D2O myself. Just electrolyze some water, and keep adding water until the D2O accumulates.

[BunBun002]

@ApolloWasReal Actually, D2O has a slightly higher boiling point than H2O. If you want to make some yourself, you can just boil it down to a very small volume. The thing is, it is pretty rare. You'd need to boil a LOT to get a very little.

[BunBun002]

@ApolloWasReal Actually, D2O has a slightly higher boiling point than H2O. If you want to make some yourself, you can just boil it down to a very small volume. The thing is, it is pretty rare, by which I mean it's naturally in fairly dilute solution in water. You'd need to boil a LOT to get a very little, though.

[ufee]

@BunBun002 You'd probably end up concentrating everything else that's in the water.

[zoltan6561]

@ufee

you can use distilled water to avoid that.

[CargoCultFilms]

6 people are dumb

[cunnidvd]

Always wear side shields when making videos.

[thebigchib]

his "Jew fro" matches mine. Except my hair is brown.

[zalvoz]

i live in Norway :) not too long from the powerplant

[maiahi0]

@zalvoz Me too, but cheap electricity don't exist in Norway.

[WHIREAS]

@zalvoz liar. You FUCKING DISGUSTING liar.

[zalvoz]

@WHIREAS xD how would u know ? haha

[WHIREAS]

@zalvoz I'm kidding, hehe. ;)

[zalvoz]

@WHIREAS yeah i kinda figured that out :) XD

[ChemistDrummer]

Shit! You have an autosampler for your NMR? ... wow....

[hanzithaking]

pause @ 5:30 :D

[Jaeger2011]

Mad Scientist?

[punishedexistence]

Oh I've tasted D20 in my chem lab class...it tastes just like normal water. You're not gonna die if you drink some; in fact deuteriated chemicals are used to label specific hydrogen positions in organic chemicals to see how they are metabolized and excreted...everyone contains a few percent hydrogen deuterium oxide in their bodies. I just wouldn't want to drink it all the time. In fact D20 is less lethal than ethanol. I like heavy metal, so I suppose I should like heavy water too.

[foroparapente]

@punishedexistence BS

[punishedexistence]

@foroparapente In Chemistry, yes I do have a 4 year degree which I suppose would be called a Bachelor of Science. Thanks for the observance.

[salerio61]

@punishedexistence I've drunk heavy water as well, tastes like water

[punishedexistence]

This man is God on Earth. Much respect to the Prof, he is wise beyond eons. Thank you for keeping my dorky nerdy geeky side alive and proficient.

[haynaku2007]

Philippines has the biggest reservoir of deuterium in the world, but unextracted. Can deuterium be used to generate electricity?

[kluts]

@haynaku2007 Using heavy water as a moderator, nuclear reactors can run on natural uranium.. Usual reactors run on enriched uranium that uses natural water.

[muchalh]

Get her a new lab coat. This looks like it's older than she is.

[nc17atnce101]

nuclear magnetic resonance testing and use it to analyze molecules

[DeepAbsentia]

What a lovely neck.

[panzarw]

so yea 2 d2o beer every day and your a gonar, and it will be very hard to from what you were killed, tho analysis of beer bottles can give out a steady percent of d2o in them so umm yeah its a problem, just sharing thoughts no intent for murder here =D

[MarkArandjus]

Those Norwegian soldiers were so using cheatcodes :P

[pinnegubbe]

@MarkArandjus No, they used ski's and TNT :D And of course average Norwegian skills :)

[thexsoar]

okay nerd alert, do you think this is the same type of Deuterium described in star trek? "Deuterium, along with its antimatter opposite, anti-deuterium, is the primary fuel used in matter-antimatter reactions, such as those generated in warp cores" or did they just like the name?

[TankzOnline]

@thexsoar

here's an ultra nerd answer. Yes it is the same stuff. Probably because it sounds "cooler" than hydrogen. They explain it by stating that anti-deuterium is the only antimatter non-reactive with di-lithium under certain conditions. Thus di-lithium is used as a "channel" to regulate the reaction between the antimatter and matter. Normal deuterium is used for matter so as to be balanced.

[AZKOJYUN]

seems 4 people put heavy water in their whiskey

[thesparitan]

@AZKOJYUN Ummm tasty

[DoDomagschokolade777]

I´ve got this printer too :)

[DeltaGale]

It says on Wiki that Heavy water is used to treat hypertension, coz it apparently lowers blood pressure. Is that true?

[DeltaGale]

LMFAO. Who cares about being dizzy when you are going to be DEAD? Maybe he really is a mad scientist... What with that hair and everything...

[ThereWasThisOneTime]

So how will a reaction with H2O that would produce hydrogen gas say with lithium and H2O. How would the reaction proceed with D2O.

[pouya97]

If you drink it you will turn temporarily to the thing

[jrwjrw88]

I remember touring Argonne Labs in the early 1970's. They were growing algea in D2O to produce deuterated biological molecules. They said this was the highest form of life that could function with hydrogen replaced by deuterium.

[BuickDoc]

The question is not CAN you drink heavy water, it is SHOULD you drink heavy water?

[AccidentalLyrics]

This is the best video yet 5 stars

[krogan92]

i bet the guy does tons of acid

[mrbonaparte]

I hear it tastes sweet. I've seen some drink it online

[theTank77]

anyone else watching the reflection of his hands in his glasses

[TheKray11]

Heavy water is very interesting.

[DBSpy1]

If he was poor, he would be considered crazy not smart.

[LemonLimeLaughter]

NMR!

[nattsurfaren]

Why is deuterium expensive if you make it by electrolysis. I mean anyone can do it with a car battery charger and some electrodes. Is there more to it?

[dunnobutwayne]

@nattsurfaren

i think you will need may more current then just a car battery ^^

[omerta410]

i love this british girl. she looks funny and she is very clever. what more sexiest in a woman?

@oBLACKIECHANoo Beauty is in the eye of the beholder.

[SETHHIKARU]

I drink very minute amounts of Deuterium Oxide every once in a while. It tastes slightly sweet for those that are wondering what it tastes like.

[csarnaes]

@SETHHIKARU why would it taste sweet, theres no sugars in it

[Juxtaroberto]

@csarnaes I think there are things other than sugars which taste sweet. For example, ethylene glycol, the main ingredient in antifreeze, is an alcohol, and it is very sweet.

[trespire]

@Juxtaroberto Ethylene glycol or monoethylene glycol should never ever be ingested. It is highly poisonous and will damage kidneys. Even in very small quantities. Could end up requiring dialasys 3 times a week for the rest of your life.

So please don't try it or suggest trying it.

[Juxtaroberto]

@trespire "So please don't try it or suggest trying it." I never did. csarnaes asked why something tasted sweet when it didn't have any sugars in it, and I stated that things don't need to have sugars in them to be sweet, and then I provided an example.

[trespire]

@Juxtaroberto Ok. I didn't intend as coming over too strong.

I had this image of some one "not too smart" (!) tasting a few drops of antifreeze just to see if it realy does taste sweet, and ending up in the emegency room with kidney failure after a few hours.

Ethyline glycol is nasty stuff to ingest.

Just thought it would be prudent to include a clear warning for anyone "smart" enough to try.

btw, any spillage on the driveway should be cleaned up and washed to prevent anyones pet from licking.

[samurphy]

@Juxtaroberto There's also a raft of artificial sweeteners in daily use that have no sugars. Xilitol, Aspartame, Sucralose, Ace-K etc. 

[Juxtaroberto]

@samurphy Yes, but they're called "sugar alcohols," so I don't know if they should be considered sugars or not. Bacteria definitely cannot digest them, which is why if you chew gum sweetened with sugar alcohols you have less bacteria in your mouth because you starve them. Also, too much sugar alcohol gives you diarrhea, which makes me think we also cannot digest them.

[Andruth34]

@Juxtaroberto

That's why they're branded as "0 calories" - our bodies cannot digest them, and therefor get no usable energy from them.

[SETHHIKARU]

@csarnaes It's a property of the Deuterium I believe. Get me some Deuterium gas and I'll try and taste it and see if that tastes slightly sweet.

[Bluestouse86]

his pubes look just like his fro.

[Achilles9924]

@Bluestouse86 and how do you know?

[Bluestouse86]

@Achilles9924 cuz i walked in on him fucking a test tube... LOL

[FlashFizz]

I think deuterated dogs would have trouble swimming due to their higher than normal density. Why not go all the way and feed pregnant dogs with superheavy water (with the oxygen-18 isotope) and foods with carbon-13 and nitrogen-15? I'm sure you can find grant money for such research.
