I compare a sample of heavy oxygen water to heavy hydrogen water. Drinking heavy water video: • Drinking Heavy Water Help me make videos by donating here: / codyslab
A million years later, some archeologists would find Cody's fossil, would be thoroughly confused by the spectrometer readings, and decide that Cody is from another planet.
Anyone thought over, why its availablity is controlled by labeling it so expensive? It is proved that, whatever is healing and benificial to public health, is always made too expensive by the corrupt system. You never know, it could be equivalent to the Elixir from the streams in the secret mountains, which we hear in stories and tales. And it could be the 'fountain of youth' type of effective. Thus they make it hard for you to procure.
12jato34 Yeah, I was about to say something about that, maybe contamination by setting everything down on the bags of sugar and that's why everything is sweet? I'm not really being serious about that, but maybe it should be considered?
samflyer80 The rate of losing water to space is like, the least important environmental issue ever, and possibly the easiest to fix if for some reason we decided it was an issue.
nikitikitano Energy is cheap when nuclear (fission, but also fusion) is an option. The main reason most "green" groups oppose it is that it's a real threat to fossil fuels, where solar isn't. Solar will always need LNG support. And many environmental groups are funded directly or indirectly by oil companies, for that reason.
Here we see the wild Cody in his natural habitat. Observe how he majestically chugs down a litre of cyanide followed by his main meal consisting of hand crushed diamonds, gold dust from computer chips and circuits, led grown cave mushrooms and heavy whipping cream with a cherry on the top picked from the tree growing in the core of the Chernobyl reactor.
Grand ɪo I think VSMOW2 (Vienna Standard Mean Ocean Water 2) might be more expensive. NIST seems to be out of stock right now (REALLY!!??? WTF!!!!!). Even GISP (Greenland Ice Sheet Precipitation) and SLAP (Standard Light Antarctic Precipitation), which are secondary standards to VSMOW2 appear more expensive than O18 water. These have standard proportions of isotopes of both hydrogen and oxygen. VSMOW2 is used to define the temperature standard.
I have some 6 foot glass tube that I plan to use. many of them are reactive but I''m trying to arrange them so those are not right next to each other course to do that I'm actually having to use chloroform mixed with mineral oil or glycerine as a separator on some of them.
You could use electrolysis on both heavy waters and then mix the oxegen from the oxegen 18 isotope and the heavy hydrogen isotope. Then burn it, while preventing any other contaminants in. You should get double heavy water.
@@zombery2472 Probably just be better ordering doubly labelled water as the losses in electrolysing and burning them would be massive and assuring you don't get a mixture of differently labelled versions would be difficult.
Diamonds are very abundant in the earth, but their supply has been very strictly controlled by the diamond industry since it began. Jewelers who get De Beers diamonds are only allowed to sell what they're given by the company, not from other wholesalers or as re-sale. Therefore, the price you pay is artificial, and the intrinsic value of that diamond is much lower.
Nothing has intrinsic value. All value is subjective, as in, humans give things value. Ask yourself, what would the value of all the gold, diamonds, etc, in the world be if there are no humans around? Exactly. :)
Of course their are things with Intrinsic value, the family unit being one of them, traditions and heritage. And of course reading if you read the OP comment again a woman taking about a diamonds have intrinsic value while the majority of them expect/want a diamond from a man. That's the only ironic thing here.
"I would like to purchase 1 gram of a highly expensive liquid that is used in the medical industry." "What do you want 1 gram of this for?" "I want to drink it." "..."
"this 1 gram of oxygen-18 water costs around $250 dollars" "I am really curious as whether it tastes the same as normal heavy water" Godspeed you magnificent man
Cody you are a fascinating man. Not only do you inspire the deep love of science and chemistry I hold but you're also so casually curious about everything. Somehow seeing you excitedly drinking random fluids or slicing your fingers to implant magnets into your flesh brightens my day. Thank you for this channel.
You could really do that by electrolyzing both heavy waters with seperated anode and cathode, and then combine it with a catalyst. I'm german, sorry for bad english...
Yo, Cody, just a tip if you haven't thought about this. You can taste something without swallowing it. Maybe it'll save your life while you're making a video eventually.
Is it possible that the deuterium pulls a little bit more on the electrons in D2O compared to the hydrogen in H2O, making the atoms slightly less polar and therefore make hydrogen bonds slightly weaker? This then could alter the way it bonds to the proteins making the taste receptors and create a different signal to the brain. This would be my hypothesis at least.
@Anton Helsgaun - I see you're jealous of the fact that he turned his brain on. He took an incredible risk in possibly being wrong.*GASP* Rather, than just repeating things he's heard ppl say.. Im sure you'll learn all about this soon while driving slow in the passing lane cuz ur too busy talking on the cellphone to pay attn to traffic around you.
Wouldn't the slightly larger nucleus make the Hydrogen less attracted to the electrons and therefore slightly more often splitting apart forming H3O+ and OH- resulting in another concentration of those rather reactive ions which could be messing with your taste buds?
O-18 H-2 water is called doubly labeled water, and it's used to measure the average rate of metabolism in the body. If you're interested about the details, look it up online.
Is it possible to have Oxygen-18 with deuterium? I'm guessing it would be very rare, and even harder to separate from normal water. Edit: watched the ending, so it is possible, but how do would you go about isolating "double-layered" water? Edit 2: Does the end clip maybe mean that another episode of beekeeping is coming? I loved the Year of Beekeeping vids!
You could make doubly labeled water by making the electrolysis of 18O water and D2O at the same time, recovering the 18O oxygen gas from the first one, and combining it with D2 from the second one back into D2O, only with 18O this time.
Hey cody a project i would like to see you do would be to try and make earth friendly desalination small scale machine that uses either the sun or some other way you could think of to make fresh water. maybe you could make a playlist of machines like this and the methane and all your others! keep up the great work love your videos !
Cody, love the experiment. If you are looking for an explanation (you are speculating a bit about it in the video): 'sweet' is detected by a protein receptor in your tongue. Hydrogen bonds between water molecules and proteins play a very important role in maintaining the conformation of proteins and their activity. The properties of hydrogen bonds with Deuterated water are much more affected than with heavy-oxygen water. Your sweet-sensor protein is very likely slightly activated in D2O because its hydrogen-bonds with the surrounding water are affected. Incidentally, that is also why too much D2O is toxic: some enzymes that are critical to your health are very dependent on certain hydrogen bonds. In D2O they do not function well enough and you die. I find your observation that the effect disappears after a meal extremely interesting. Maybe the food is not simply deadening your taste buds for a while, but what is really happening is that your body is actively modifying your taste perception to make sure that your food preference matches what your metabolism needs?

Its to slow down the metabolism, you know oxygen is needed for your muscles to generate movement through energy won out of sugar, oxygen 18 is heavier so the blood carrying it flows a bit slower and the muscles have to put more effort to use this oxygen... no thats stupid, ive made it all up.
@Cody'sLab The ratio of O18 to O17 is is also really important for reconstructing past climate, often looked at in the ratio in ice cores and shells of ocean organisms like benthic foramanifera. Kinda awesome how just by looking at the shells of some 'bugs' that live at the bottom of the ocean we can figure out some aspects of climate over the last few million years.
