So the list of the most expensive waters would go like this: 1-Normal water 2-Heavy water 3-Super heavy water 4-Bottled tap water at a pop music festival 5-Water at the airport
I'm a nutritionist and drank heavy water once in school for one of the experiments Hank briefly mentioned. Just one of the most expensive and awesome ways of measuring a person's total energy expenditure. Heavy water tasted, looked and felt exactly like regular water as far as I could tell.
And since heavy water often sits around for a long time after it is isolated, it is likely going to be very flat tasting, bordering on musty. Not the best cup of water you have ever drank. Though they may aerate it before giving it to humans to consume purely for the taste, though.

I am a member of a structural biology lab and we work a lot with heavy water. My lab uses the deuterium in D2O (heavy water) to label proteins, put the proteins through a pepsin column (pepsin is an enzyme that chops up proteins), and then load the peptides onto the mass spectrometer. Using this method, we are able to learn very valuable information regarding protein conformation and protein dynamics. So yes, D2O is awesome! It is also extremly expensive...
Lokeshwar Bhenderu Yeah...no kidding. Official systems for D20 are expensive (I'm looking at you, D&D). Bad geek/nerd joke about tabletop gaming based on the way you had to write things due to keyboard limitations. I shall show myself out.
Kyco Presumably you would be more buoyant (as you would displace less water) and so potentially could encounter less drag. But then maybe you'd have increased drag from the water infront of you. But then you'd be able to get more thrust with each stroke/kick. I think you'd be faster as I think the total amount of water 'blocking' your path would have equal mass in both heavy and normal water, but the force you can apply is dependent on the area of your hand/arm/foot which doesn't change but what you're pushing against is more 'massive' propelling you forward more.
A swimmer in oil isn't really comparable, since oil has a much higher viscosity than H2O or D2O. But you certainly would float much more easily! To clarify the above, you would displace the SAME amount of water by mass, meaning a smaller volume of water displacement would be required to keep you from sinking. A D2O swimming pool would be way cool!
@@Robbythegod some oils are more or less viscous. I imagine sewing machine oil would be close to water, where something like heavy crude would be super viscous even if it is lighter weight than the water by 10-20% (I can't remember off hand).

I have heard people describe the taste of heavy water as tasting like normal water, but much sweeter.

Here is a question for you SciShow... Car Seats have an expiration. Why? I have done my research and can't find data that backs up any of the claims. I understand if it had been in a wreck or has outdated safety standards, but plastic and straps don't expire in 6 years.
lhsalmond, I assume you talk about car seats for child. Plastic is not an eternal material. After a while, it dries up (or other physical effect) and becomes less flexible and more brittle. Simple old LEGO bricks do not have the same feeling after 20 years, especially compared to new ones. The plastic of a car seat is bulkier, so you will probably not feel any difference after a couple of years. However, the dry up has weakened enough the plastic so that a full impact of an accident will brake it. Last time I heard about it, the expiration date was 10 years in Canada. I am surprise it is only 6 years in some places.
Ghyslain Abel I understand that plastic could get brittle over time, but those kind of things happen over decades. And the manufacturers claim that sitting in a box or sitting in the sun dont affect that. There are no images online of wrecked "expired" carseats that have been in accidents, and there arent any tests that compare equivalent carseats that were made 6 years apart. I work in the plastics industry, and this smells really fishy. I agree safety standards may improve over a decade, which makes switching make sense, but I personally think it is just there to compel scared moms to give them more money and kill any litigation on seats over 6 years old.
lhsalmond, I understand your point. You are probably right, manufacturers put too short expiration date to do more sales. By the way, what about temperature? In winter it can be as cold as -30 outside, and each time the car is used the temperature goes up to 10 with the heating. In the summer, the inside of a car goes up to 45, then it is cooled down to 25 with air conditioning. They are both temperature swings that plastic does not usually have inside a house or inside a factory. I am just thinking about outside playground. Plastic slides, after a couple of years, lose their colour and have some surface cracks. Since the biggest impact the can receive is a child jumping on it, it is not dangerous. A car seat must resist to a accident at 100 km/h (300 km/h in Germany).
You think child car seats expiring is bad, the seat belts used in race cars expire after (usually, depending on sanctioning body) 3-5 years and a car with expired belts won’t be allowed to compete. In both cases, seats and belts, this has very very little to do with the actual hardware and everything to do with insurance liability. No company wants to be on the hook when little Johnny gets killed in a 20 year old car seat, so the law allows a limitation on the liability after a certain number of years. That’s what has expired: the manufacturer’s liability.
Distilled water costs .80 a gallon. And most of it is distilled in Los Angeles, and Georgia. There they boil the water, and collect steam, and then bottle the steam, which becomes saltless water, also called distilled water. Very friendly.
@scishow: You forgot to mention, that your body has a proton-pump. If your body has only D2O, there is no more normal proton source, since all ionized heavy-hydrogen will be stuck to a neutron, making it too big to work in the proton-pump.
You risk denaturing your proteins in your metabolic processes if you raise your temperature plus, your body needs catalysts and speed boosts for you reaction otherwise you risk dying.
Deuterium in low concentrations, for example above 140 ppm also has a deleterious effect on mitochondria through damage to proton pumps in the electron transfer mechanisms that produce ATP for cellular energy.This damage is cumulative over many years. Examples include: All Vegetable oils btw 250 and 300 ppm. Nnn Alpine sources of water 140+ ppm depending on source.
I've always learned it's not so much the heavy water being toxic it's the lack of normal water that might hurt you. So you'd need to replace pretty much all your water intake with it.
I think it would be great if you made an episode on how Slide Rules work. After all they helped with some of the greatest construction projects world wide at the time an even helped check the work of NASA. I think it would make for an excellent episode.
What about demineralized water? I drank some by accident and it was like I didn't drink anything, my mouth was still dry. So what if you drink a lot of it? Edit: Talking about the water you get from the air dryers.
@@neilisbored2177 Which is exactly the temperature at which Deuterium boils! Also, maybe there are some comments doing weight related jokes about Cody's Lab or so.
Hey guys, would you consider doing a video on why glass from some old camera lenses have thorium mixed in with them? Thoriated lenses aren't dangerous, but they would have been if you kept one on your night stand each night, since thorium emits alpha beta and gamma particles.
Can there be water made from a non-"normal" isotope of oxygen? Like, if it was made from two "normal" hydrogen atoms that have no neutrons, and an oxygen atom that has nine neutrons instead of eight?
Oxygen-18 (10 neutrons) would be about 5 times more likely for that. In reality, you probably do have some water with non Oxygen-16 oxygen as well as some D2O.
I don't know about you it woukd probably have the same effect, given how everything organic has hydrogen in them and a crapton of them also have a bunch of oxygen too.
Tritium isn't USED in nuclear reactors, it's CREATED in fission reactors. And tracking its amount and discharge are a SUPER important thing at a plant.
BTW, it get's out through migration through metal. There is literally no way to stop it getting out :) Enjoy that. But it's perfectly safe and can't be released near any water sources unless HEAVILY diluted, like by a BIG river.
It doesn't work like that. What you need for a fire is an oxidising agent, the most common being O2, but not every substance containing oxygen is an oxidizer. That's why you can't breath water either.
@@kevinlusdanar8316 Making a fire needs all of the three rules to maintain one. Temperature, Fuel and Oxygen... taking any of these away will cause the fire to extinguish. So oxygen in water doesnt make the fire any stronger if temperature is being lowered anyway.
@@kevinlusdanar8316 Applying heat to water does not break the bond between hydrogen and oxygen. The oxygen stays with the hydrogen and so does not bond to the fuel source. That's why water does not burn.
Folks are assuming that heavy water is D2O (Di-Deuterium Oxide), but in reality most of it will be DHO, that is only one regular Hydrogen atom will be swapped out for a Deuterium atom. Then, as someone else has pointed out, there is also the possibility of making heavy water by going to a heavier isotope of Oxygen. All three atoms can have extra neutrons added, making for many possibilities. But most of the time, heavy water is DHO.
The questions I have after this video and another one I recently watched is does heavy water freeze like normal water? Does it then make heavy ice and heavy ice 2 etc.
Heavy water is the premise and murder weapon in the 1934 novel The Casino Murder Case by SS Van Dine, whose Philo Vance mysteries were huge bestsellers in their day. This was just shortly after it was first discovered, so I guess nobody realized how much of it you'd have to drink to be poisoned yet. It was made into a movie in 1935 starring Rosalind Russell, and this probably accounts for many of the later appearances in pop culture.
Actually, almost instantaneously on contact (unless it's frozen) the heavy-water will share its deuterons with ambient normal (light) water-etc., producing semi-heavy-water-etc....
Brilliant also have an app and it is really great. I've had it installed for months as it peeked my interest, but I haven't had time to truly dig into it yet, however I can say that it's really great so far.
Hello, SciShow! Do you think you could make a video explaining the current knowledge of cerebral aneurysms? I had one rupture at 19 and after learning so much about them, I would love for a bigger audience to learn of them!
I have no idea what you're talking about. I tried searching for Scishow or brain aneurysm copypastas but got nothing. The only Scishow copypasta I know of is "Why is there _________ around my anus?"
An episode of the 1960s sitcom "Hogan's Heroes" had our erstwhile POWs somehow acquiring a barrel of heavy water. They, of course, wanted to get rid of it in order to slow down German nuclear research. They decided the best way to dispose of it would be to feed it to the camp commandant, Col. Klink. Hilarity ensued. Apparently, physics and biochemistry didn't overly concern the writers because the good Colonel suffered no lasting ill effects. Even when I was just 12 years old, I couldn't figure out why they didn't just dump it into the latrine. That's where it ended up anyway.
Dylan Vellut Weird, since it’s chemically similar to normal water, so it should interact with our taste receptors in the exact same way as normal water.
Peter Knutsen first our senses are not exactly the same for everyone (like for urine and asparagus). I'm into chemistry but the way our taste buds work is completly unknown to me. I would just assume D2O tickle the sweetness receptor the right way to make us feel that, as well as pepperine and carvone
So question. D2o (heavy water)= longer reaction in humans to use which is bad H2O (water) = balanced reaction in humans which is good ? (Light water) = shorter reaction in humans which would have potential to be greater use to our bodies, or detrimental because our bodies can't process that fast of a reaction. My question. What would light ice be and would it be better for us than normal water or could it be used as a natural energy drink or a true diet drink that would help in weight loss and increase cognition?? Truly curious if there is an answer
C-D bongs are not stronger than C-H bonds. The isotope effect is due to the higher kinetic energy required to break a C-D bond as D is heavier than H. The result is that the reactions are slower, hence slower metabolism in an animal.
Glass powder? Probably not much (you may as well be eating fine sand). Glass shards? Your mouth (among other things) will get sliced. Either way, glass isn't digestible, so, you know, just don't eat glass.
Also, if you've been dehydrated into a pile of powder, being re-hydrated with heavy water makes you unstable. You'll pop into nothing when Batman hits you!
Next question - what happens when you drink Hard water. (water with salts dissolved in it?) A - Nothing. I lived in a desert area where water was derived from the ground and hard water was common. Tastes poor. Doesn't really quench thirst much. I guess you get a lot of minerals from it. Also it's terrible for washing anything with soap.
Couple things Hank, H1 is sometime referred to as Protium just as H2 is referred to as Deuterium and H3 is referred to as Tritium. Also, Di-Tritium Oxide is really bad. The worst types of radiative isotopes to have internally are Beta and Alpha emitters, especially Alphas. As someone who has a degree in Nuclear Engineering, we were always taught when it comes to radiation that is are external sources of alphas or betas weren't as worrisome as external sources of gammas and neutrons because the top layer of skin will stop alphas and depending on how energetic the betas were, they'd likely be stopped in the upper layers of skin (although high energy betas could penetrate deeper) where as gammas and neutrons would likely interact multiple times at various depths in the body as they pass through you. Been when you reverse it, where the sources are internal, Alpha and Beta emitters are far worse because they will lose all their energy internally to the human body and gamma and neutron emitters aren't as bad as they will quickly exit the body without depositing much energy. So, TLDR for radioactive sources, Alphas and Betas outside the body, not an issue normally, Alphas and Betas inside the body, really, really bad.
1:52 There *is* a strange use for drinking heavy water. Relieving "the spins" from drinking too much alcohol. Seriously. "The spins" are caused by the fluid in the cupula, the part of the inner ear that is responsible for maintaining balance, being too dilute. The room always spins the same way, clockwise, after drinking too much alcohol. Drinking a small amount of heavy water apparently is a quick remedy for this, as it somehow changes the overall density of the inner-ear fluid to counterbalance the effects of consuming too much alcohol. Don't actually do this outside of a lab setting though. Or perhaps even in one, unless you're a researcher on sensation and perception.
Back when (1932) Heavy water was first isolated by Harold Urey, it was an expensive process. Is it now so cheap that anyone could afford to drink a glass of it? Certainly certain scientific discoveries have led to silly fads, like e.g. sniffing N2O, but it seems unlikely that heavy water binge drinking (with perhaps some super-heavy water as a chaser) will ever catch on.
0:30 Kinda weird that you're showing a model of a water molecule while discussing the atomic composition of deuterium, only to swipe it off when actually getting to the water part. Unless that's supposed to be a proton and two neutrons, which would be _tritium?_
I only use deuterium and tritium for secondary fusion. With nuclear fission from uranium, plutonium, even thorium, it disperses much more energy. After all, deuterium and tritium have the strongest repulsion together which can not be said in comparison of "other" elements.
Given the fact stated that the bonds in D2O are harder to break, I'd guess the opposite: it takes more energy to break the bonds, therefore the body needs more Energy/ATP/Calories to do what it needs to do. So if your body is able to adapt to the change, your metabolism would need to speed up to match the energy requirements, or if nothing changes, you'd probably just feel a bit more lethargic while the heavy water is in your system.
This is a very interesting topic. Thanks SciShow. Well you probably all know that water you drink is H2O that stands for 2 atoms of hydrogen and 1 atom of oxygen. Some of you maybe know about isotopes and that every element in the periodic table has more then 2 isotopes. Isotopes are essentially atoms with the same number of protons and electrons but different number of neutrons in its core. Hydrogen has 3 isotopes as said in the video but nobody mentioned that oxygen has 16 isotopes from which 3 are stable and found in nature. Normal water hound on Earth is made from [1]H and [16] O but theoretically in the different conditions like high pressure water made of [3] H and [28] O would be possible. That would be the heaviest water possible. Also there are 96 different water molecules possible to exist. Also an interesting topic. Would the water form different planets be usable for humans if it is made from different percentage of water molecules from mixture present on Earth?
Question What is the effect of nuclear explosions in the upper layers of the atmosphere? Assuming missile defense system blows up missiles in the sky.. what if the missile was an ICBM? I remember watching a video on the nuclear tests conducted in outer space, that didn't really work out well of us humans.
Sorry Hank, but I'm going to have to correct you. The D2O bonds are exactly the same strength as H2O. The difference has to do with rotational, vibrational, and translational energy states in thermal motion. The deuterium has greater mass and thus moves slower even with equivalent energy.
So the list of the most expensive waters would go like this:
1-Normal water
2-Heavy water
3-Super heavy water
4-Bottled tap water at a pop music festival
5-Water at the airport

Plastic is not an eternal material. After a while, it dries up (or other physical effect) and becomes less flexible and more brittle. Simple old LEGO bricks do not have the same feeling after 20 years, especially compared to new ones.
The plastic of a car seat is bulkier, so you will probably not feel any difference after a couple of years. However, the dry up has weakened enough the plastic so that a full impact of an accident will brake it.
Last time I heard about it, the expiration date was 10 years in Canada. I am surprise it is only 6 years in some places.
Ghyslain Abel I understand that plastic could get brittle over time, but those kind of things happen over decades. And the manufacturers claim that sitting in a box or sitting in the sun dont affect that. There are no images online of wrecked "expired" carseats that have been in accidents, and there arent any tests that compare equivalent carseats that were made 6 years apart. I work in the plastics industry, and this smells really fishy. I agree safety standards may improve over a decade, which makes switching make sense, but I personally think it is just there to compel scared moms to give them more money and kill any litigation on seats over 6 years old.
lhsalmond, I understand your point. You are probably right, manufacturers put too short expiration date to do more sales.
By the way, what about temperature? In winter it can be as cold as -30 outside, and each time the car is used the temperature goes up to 10 with the heating. In the summer, the inside of a car goes up to 45, then it is cooled down to 25 with air conditioning. They are both temperature swings that plastic does not usually have inside a house or inside a factory.
I am just thinking about outside playground. Plastic slides, after a couple of years, lose their colour and have some surface cracks. Since the biggest impact the can receive is a child jumping on it, it is not dangerous. A car seat must resist to a accident at 100 km/h (300 km/h in Germany).
Money. Its the same thing with prescription drugs, do you really think morphine goes bad after 12 months? Every chemical has a half life.
You think child car seats expiring is bad, the seat belts used in race cars expire after (usually, depending on sanctioning body) 3-5 years and a car with expired belts won’t be allowed to compete. In both cases, seats and belts, this has very very little to do with the actual hardware and everything to do with insurance liability. No company wants to be on the hook when little Johnny gets killed in a 20 year old car seat, so the law allows a limitation on the liability after a certain number of years. That’s what has expired: the manufacturer’s liability.
Distilled water costs .80 a gallon. And most of it is distilled in Los Angeles, and Georgia. There they boil the water, and collect steam, and then bottle the steam, which becomes saltless water, also called distilled water. Very friendly.

Thee DoubleD Why did you do this to me?
Wow, now I can't unsee that.
What do you mean look like.
@scishow: You forgot to mention, that your body has a proton-pump. If your body has only D2O, there is no more normal proton source, since all ionized heavy-hydrogen will be stuck to a neutron, making it too big to work in the proton-pump.
If heavy water slows reactions down a bit, what if you compensated by making your body temperature higher?
You risk denaturing your proteins in your metabolic processes if you raise your temperature plus, your body needs catalysts and speed boosts for you reaction otherwise you risk dying.
@@NoirMC187so how about heavy water mixed with some of those catalysts and speed boosts?
Deuterium in low concentrations, for example above 140 ppm also has a deleterious effect on mitochondria through damage to proton pumps in the electron transfer mechanisms that produce ATP for cellular energy.This damage is cumulative over many years.
Examples include:
All Vegetable oils btw 250 and 300 ppm.
Nnn Alpine sources of water 140+ ppm depending on source.
250 to 300 ppm is very high. No wonder why vegetable oils make people sick.

Worth it.

Nathaniel Darkwater if that’s sarcasm, just get off the page.
I've always learned it's not so much the heavy water being toxic it's the lack of normal water that might hurt you. So you'd need to replace pretty much all your water intake with it.
I think it would be great if you made an episode on how Slide Rules work. After all they helped with some of the greatest construction projects world wide at the time an even helped check the work of NASA. I think it would make for an excellent episode.
What about demineralized water? I drank some by accident and it was like I didn't drink anything, my mouth was still dry. So what if you drink a lot of it?

Hey guys, would you consider doing a video on why glass from some old camera lenses have thorium mixed in with them? Thoriated lenses aren't dangerous, but they would have been if you kept one on your night stand each night, since thorium emits alpha beta and gamma particles.
So if you have to subsist on salt water or heavy water which should you pick? Which one will let you live longer?
Good question. I want to know this too.
Can there be water made from a non-"normal" isotope of oxygen? Like, if it was made from two "normal" hydrogen atoms that have no neutrons, and an oxygen atom that has nine neutrons instead of eight?
Oxygen-18 (10 neutrons) would be about 5 times more likely for that. In reality, you probably do have some water with non Oxygen-16 oxygen as well as some D2O.
Codys Lab drank it
KingsleyIII yes
I don't know about you it woukd probably have the same effect, given how everything organic has hydrogen in them and a crapton of them also have a bunch of oxygen too.
David as far as I know, Cody's lab drank only D2O
Best one is tritium oxide!
Holy cow, this was something they had Hogan's Heros!
I remember that episode. Klink and Schultz drank quite a bit of that barrel!
(Actually, that explains a lot! 😆)
I bought d2O for my inverter just now without knowing it's name. I just called it inverter water at the shop and now UA-cam recommends me this.
Note to self, don't drink too much heavy water.
More chemistry and physics episodes, those are topics that will likely engross most viewers, dont know for certain though
Umm Cody's lab
Only difference is that Cody also did oxygen-18 heavy water and SciShow explored the toxicity of deuterium oxide (which itself is an open question).
What about Cody's lab? You have an incomplete sentence.
LuisTheBubble What is Cody's lab
search on youtube, he has a video where he drinks some heavy water, you will like it
Billy big bollocks
Tritium isn't USED in nuclear reactors, it's CREATED in fission reactors. And tracking its amount and discharge are a SUPER important thing at a plant.
BTW, it get's out through migration through metal. There is literally no way to stop it getting out :) Enjoy that. But it's perfectly safe and can't be released near any water sources unless HEAVILY diluted, like by a BIG river.
If it slows chemical reactions down, would it be more effective at stopping fires than regular old h2o?
water stops fire by mechanical, not chemical means. It cuts the supply of oxigen and cools off the surfaces preventing it from burning again.
@@nashooo5903 but water is h2o right ?
So it has oxygen in it
It doesn't work like that. What you need for a fire is an oxidising agent, the most common being O2, but not every substance containing oxygen is an oxidizer. That's why you can't breath water either.
@@kevinlusdanar8316 Making a fire needs all of the three rules to maintain one. Temperature, Fuel and Oxygen... taking any of these away will cause the fire to extinguish. So oxygen in water doesnt make the fire any stronger if temperature is being lowered anyway.
@@kevinlusdanar8316 Applying heat to water does not break the bond between hydrogen and oxygen. The oxygen stays with the hydrogen and so does not bond to the fuel source. That's why water does not burn.
Folks are assuming that heavy water is D2O (Di-Deuterium Oxide), but in reality most of it will be DHO, that is only one regular Hydrogen atom will be swapped out for a Deuterium atom. Then, as someone else has pointed out, there is also the possibility of making heavy water by going to a heavier isotope of Oxygen. All three atoms can have extra neutrons added, making for many possibilities. But most of the time, heavy water is DHO.
The questions I have after this video and another one I recently watched is does heavy water freeze like normal water? Does it then make heavy ice and heavy ice 2 etc.
Yes. The cubes will sink in normal water. There's a UA-cam short about it. Wish I could remember the name of the content creator.
Heavy water is the premise and murder weapon in the 1934 novel The Casino Murder Case by SS Van Dine, whose Philo Vance mysteries were huge bestsellers in their day. This was just shortly after it was first discovered, so I guess nobody realized how much of it you'd have to drink to be poisoned yet. It was made into a movie in 1935 starring Rosalind Russell, and this probably accounts for many of the later appearances in pop culture.
Now let me ask ya this. What's the IQ of smart water?
It's called Smart Water because it takes intelligence away fro people, so they'll pay an extra dollar for it compared to generic.
@Phục Đạt Đức Be careful not to cut yourself on that edge :D
Not very high, they can't even get out of the bottle

Actually, almost instantaneously on contact (unless it's frozen) the heavy-water will share its deuterons with ambient normal (light) water-etc., producing semi-heavy-water-etc....

Hello, SciShow! Do you think you could make a video explaining the current knowledge of cerebral aneurysms? I had one rupture at 19 and after learning so much about them, I would love for a bigger audience to learn of them!

Solis its a copypasta
I have no idea what you're talking about. I tried searching for Scishow or brain aneurysm copypastas but got nothing. The only Scishow copypasta I know of is "Why is there _________ around my anus?"
An episode of the 1960s sitcom "Hogan's Heroes" had our erstwhile POWs somehow acquiring a barrel of heavy water. They, of course, wanted to get rid of it in order to slow down German nuclear research. They decided the best way to dispose of it would be to feed it to the camp commandant, Col. Klink. Hilarity ensued. Apparently, physics and biochemistry didn't overly concern the writers because the good Colonel suffered no lasting ill effects.
Even when I was just 12 years old, I couldn't figure out why they didn't just dump it into the latrine. That's where it ended up anyway.
DOES IT TASTE DIFFERENT??
Water is tasteless. The taste in water comes from the minerals (mainly the amount of sodium) in it.
Tyler Harris apparently it tastes slightly sweet
it taste sweet (check out Cody's Lab channel)
Dylan Vellut
Weird, since it’s chemically similar to normal water, so it should interact with our taste receptors in the exact same way as normal water.
Peter Knutsen first our senses are not exactly the same for everyone (like for urine and asparagus). I'm into chemistry but the way our taste buds work is completly unknown to me.
I would just assume D2O tickle the sweetness receptor the right way to make us feel that, as well as pepperine and carvone
So question.
D2o (heavy water)= longer reaction in humans to use which is bad
H2O (water) = balanced reaction in humans which is good
? (Light water) = shorter reaction in humans which would have potential to be greater use to our bodies, or detrimental because our bodies can't process that fast of a reaction.
My question.
What would light ice be and would it be better for us than normal water or could it be used as a natural energy drink or a true diet drink that would help in weight loss and increase cognition?? Truly curious if there is an answer
Just ask Cody
C-D bongs are not stronger than C-H bonds. The isotope effect is due to the higher kinetic energy required to break a C-D bond as D is heavier than H. The result is that the reactions are slower, hence slower metabolism in an animal.
Soo is the video game Heavy Rain actually referring to Deuterium!?
Drinking D2O is desirable because it tastes sweet. The same reason ancient cultures used lead goblets.
So normal water is diet water?
This is so fascinating. I never knew there was so much to consider when stitching up an injury!
What happens when you eat glass?
It depends on how jagged the glass is. Eating smooth glass beads probably won't hurt you. Eating jagged glass is not so safe.
CONCLUSION: JUST DON'T DO IT
just eat sand instead, it'll have the same chemical properties without you know, cutting you.
Glass powder? Probably not much (you may as well be eating fine sand).
Glass shards? Your mouth (among other things) will get sliced.
Either way, glass isn't digestible, so, you know, just don't eat glass.
You poop glass
Also, if you've been dehydrated into a pile of powder, being re-hydrated with heavy water makes you unstable. You'll pop into nothing when Batman hits you!
So you're saying heavy water is a weight loss drug?
Next question - what happens when you drink Hard water. (water with salts dissolved in it?)
A - Nothing. I lived in a desert area where water was derived from the ground and hard water was common. Tastes poor. Doesn't really quench thirst much. I guess you get a lot of minerals from it. Also it's terrible for washing anything with soap.
You gain weight?
KingsleyIII .... ya...
shh...
Couple things Hank, H1 is sometime referred to as Protium just as H2 is referred to as Deuterium and H3 is referred to as Tritium.
Also, Di-Tritium Oxide is really bad.
The worst types of radiative isotopes to have internally are Beta and Alpha emitters, especially Alphas. As someone who has a degree in Nuclear Engineering, we were always taught when it comes to radiation that is are external sources of alphas or betas weren't as worrisome as external sources of gammas and neutrons because the top layer of skin will stop alphas and depending on how energetic the betas were, they'd likely be stopped in the upper layers of skin (although high energy betas could penetrate deeper) where as gammas and neutrons would likely interact multiple times at various depths in the body as they pass through you. Been when you reverse it, where the sources are internal, Alpha and Beta emitters are far worse because they will lose all their energy internally to the human body and gamma and neutron emitters aren't as bad as they will quickly exit the body without depositing much energy.
So, TLDR for radioactive sources, Alphas and Betas outside the body, not an issue normally, Alphas and Betas inside the body, really, really bad.
"I drank some of that water. . . . Will I die?"
"Only if Berlin finds out."
1:52 There *is* a strange use for drinking heavy water. Relieving "the spins" from drinking too much alcohol. Seriously.
"The spins" are caused by the fluid in the cupula, the part of the inner ear that is responsible for maintaining balance, being too dilute.
The room always spins the same way, clockwise, after drinking too much alcohol. Drinking a small amount of heavy water apparently is a quick remedy for this, as it somehow changes the overall density of the inner-ear fluid to counterbalance the effects of consuming too much alcohol.
Don't actually do this outside of a lab setting though. Or perhaps even in one, unless you're a researcher on sensation and perception.
Where can i get my hands on heavy water? I need to make. Bom..... uhh im thirsty
Back when (1932) Heavy water was first isolated by Harold Urey, it was an expensive process. Is it now so cheap that anyone could afford to drink a glass of it? Certainly certain scientific discoveries have led to silly fads, like e.g. sniffing N2O, but it seems unlikely that heavy water binge drinking (with perhaps some super-heavy water as a chaser) will ever catch on.
"I'll stick with this, because it's something I understand" is basically the motto of every red state.
so deuterium would be good for fields of grass you don't want to cut, like schools and football fields, plants would live but wouldnt thrive
Just watch Cody's Lab.
Danny Vasquez "someone covered this topic as well go watch him not hank hurrdurr"
0:30 Kinda weird that you're showing a model of a water molecule while discussing the atomic composition of deuterium, only to swipe it off when actually getting to the water part. Unless that's supposed to be a proton and two neutrons, which would be _tritium?_
This sounds like the perfect untraceable poison to me.

Thats very disconcerting that that was was your first thought.
However...thats def one worth checking out if you ever decide to roll a assasin irl lol
madison king
But it's heavy though.... anyone drinking it should be able to tell they're not drinking regular water
I only use deuterium and tritium for secondary fusion. With nuclear fission from uranium, plutonium, even thorium, it disperses much more energy. After all, deuterium and tritium have the strongest repulsion together which can not be said in comparison of "other" elements.
If heavy water slows down everything, does it mean small amounts of it slows down your metabolism thus making you live longer?
Given the fact stated that the bonds in D2O are harder to break, I'd guess the opposite: it takes more energy to break the bonds, therefore the body needs more Energy/ATP/Calories to do what it needs to do. So if your body is able to adapt to the change, your metabolism would need to speed up to match the energy requirements, or if nothing changes, you'd probably just feel a bit more lethargic while the heavy water is in your system.
I read, it's destructive inside of our cells. The Mitochondria is slowed down because of its size.
This is a very interesting topic. Thanks SciShow.
Well you probably all know that water you drink is H2O that stands for 2 atoms of hydrogen and 1 atom of oxygen. Some of you maybe know about isotopes and that every element in the periodic table has more then 2 isotopes. Isotopes are essentially atoms with the same number of protons and electrons but different number of neutrons in its core. Hydrogen has 3 isotopes as said in the video but nobody mentioned that oxygen has 16 isotopes from which 3 are stable and found in nature. Normal water hound on Earth is made from [1]H and [16] O but theoretically in the different conditions like high pressure water made of [3] H and [28] O would be possible. That would be the heaviest water possible. Also there are 96 different water molecules possible to exist. Also an interesting topic. Would the water form different planets be usable for humans if it is made from different percentage of water molecules from mixture present on Earth?

If it slows chemical reactions down, it would also slow the aging process down. A glass a day might add years to your life.
That's not how it works. Slowing down your biological reactions doesn't make you live longer, it just kills you.
Technically it adds negative years
Sorry Hank, but I'm going to have to correct you. The D2O bonds are exactly the same strength as H2O. The difference has to do with rotational, vibrational, and translational energy states in thermal motion. The deuterium has greater mass and thus moves slower even with equivalent energy.
