GlitchyShadow in the name of science and our entertainment. Shockingly this was one of the most dangerous of his experiments because of how this could go so wrong N
He isnt really killing himself tho... He is just avoiding safety precautions. Is like pointing an unloaded gun at your face, they tell you not to, but nothing bad will happen. I dont know how this comparaison came to my mind if im not american Mmm
peekayboo I was gonna get all pissed saying that he is only taking time of his life with this stuff in the case he died because of lead poisoning or something lile that... Then I noticed that 2016-2011=5 Shit
I can hear it now... 'See... it will form a protective oxidation layer in the lining of my mouth, so as long as I don't let it get into my lungs, I'll be fine.'
Oxygen is an element too, and it's the origin of the term "oxidizer". Whether a substance is an oxidizer or not is not determined if it's and element or a molecule, but by its ability to rip off electrons from other atoms or molecules (or more exactly, from the atoms of a molecule). Propably one of the best oxidizers known to humanity is chlorine trifluoride, under most circumstances it's a way stronger oxidizer that oxygen itself; it's so strong that it can even make concrete (and nearly every other material besides of fluorine salts) burst into flames and become absolutely inextinguishable.
I dunno but I'm just gonna say I know the human body can't get rid of heavy metals and that's how tattoos work so if he has been exposed to enough it may be affecting him
Dental hygienist: "Uh... So... Have you been flossing?" Cody: "Every day, why?" Dental hygienist: "Um, don't worry about it. Doctor, could you come and look at this?"
Gareth Dean Are they spitting the excess oil after eating hot peppers? given the fact that capsaicin is soluble in oils... Why would they do that if not for this reason?
Cry stics Capsaicin binds to human nerve endings because they're largely phospholipid, in the watery confines of the mouth they're the best surface to absorb onto. If however oil is present *this* becomes the medium the capsaicin prefers to dissolve in, lowering its concentrations on cell surfaces. This is why milk is a traditional remedy, the particles of fat it contains absorb the spice.
I saw the vid's description and thought "Cody is either completely nuts or he hasn't seen Thunderf00t's stuff about Coulomb explosions." Not very far into the video you mentioned Coulomb explosions. Ergo, you're completely nuts. Glad you survived, though.
The potassium is interesting. I wonder if folding a flat piece over on itself and then flattening and then over on itself multiple times puff pastry style would produce a more vigorous result because of the trapped layers of air? Other shapes also might produce interesting explosions. A hollow tube could trap a quantity of hydrogen?
Speaking of potassium, would it be possible to make your own potassium ion battery? The potassium ion battery is supposed to have the cycle life of a nickel-iron battery with the capacity of a lithium-ion battery.
Cody since the sodium and potassium are shapeable by hand have you tried making diff shapes i.e. cube, pyramid, ball, teardrop, ring, disc, waiffer, bell, bowl, cyliders, ECT. and droping them in liquid to see if the shape effect reaction rate and or increases the violence force magnatued or power of reaction. and is this change due to increased surface area or due to depth it falls threw the water due to new shape.. dose velocity of the metal entering the water cause a diff in effect. maybe a video where you use a clear tank with water but you float 3-5 inches of an oil. also it could you find out if the burn or reaction rate changes under pressure and in vacume. oh and what is the shock sensitivity of sodium and potassium metals if i say place a small ammount or waiffer on my anvil and hit it with my 3lb hatchpin will it react will it fuse... SCIENCE
Once upon a time Cody got annoyed that his chemistry lab TA jumped him for adding water to vinegar. Since then he has made videos that make every chemistry lab TA ever freak out. The moral of his story? Don't swallow all the chemphobia dogma hook, line, and sinker. Some things aren't that big of a deal, some things are. Respect and understanding go further with calm and cool emergency response, rather than fear and freakout.
ScratchMB the reaction forms sodium/potassium hydroxide with water, which are very strong alkalines and highly corrosive. The heat from the reaction will also add to that. Keep in mind that strong alkaline solutions like this are more dangerous to your skin than e.g. hydrochloric acid, because the alkalines can break through the fat layers of your body, which the acid can't. Then there is the risk of a coulomb explosion. During the reaction with water, the metal loses electrons to it at a faster rate than it does atoms. As a result, the metal will have excess positive charges which all repel each other. At one point, the repelling force will overcome the bond between the metal atoms and it explodes.
What he is doing is possibly deadly, and he should likely stop but it is his choice, and if it harms him, his fault. I would sort of miss him and his awesome videos.. but his choice, not ours. I have no problem with you pointing out that he should take a little more time before doing things like these, or that they are stupid stunts but the fact you feel as if it is an order.. Also please, don't use caps lock.
Have I ever mentioned you are like the Steve Irwin of chemistry dude "check this out, oi'm gonna take a bite out of this sodium roight here and it's gonna really piss him off, Terri 'ave ya got the camera ready?"
Literally will never be able to see him any other way from now on lol. "Roight so I've got this magnet roight here. Now I've coated in in a gold plating because otherwise it would be right pissed off. Now I'm just gonna carefully insert 'em in to my ring finga..."
★ TazerYT ★ Not toxic so much as corrosive, in this case. In contact with water it steals a hydroxide group (outgassing hydrogen) and forms lye. This reacts with proteins and fats, which is why Cody mentions the tip of his tongue turning to soap.
Many metals are the opposite of toxic and are actually minerals the body needs and will use to form salts and other compounds that the cells need. sodium, iron, magnesium, potassium, calcium are all examples of minerals the body uses. some metals and the heavy metals are toxic to humans, mostly because they can replace other minerals and form different versions of the salts and compounds in the cells that actually inhibit the cells function and can make them die. Mercury, Lead, Aluminium are some examples of toxic metals that do this in your body.
What would happen if you took a piece of sodium about the size of a quarter and dripped one small drop of water on to it? Would it just fizz, or melt the sodium?
It is because of the electrons on the outer layer of the metals atoms. When light reflects off the electrons, it emits a light wave that we recognise as the silver colour. (I learnt that in my chemistry class mid last year)
Most metals reflect all visible light equally and will appear as mirrors if polished. Rough metal surfaces lose some of the light and appear greyish. Some metals like copper also absorb visible wavelengths and are colored.
Kenneth Clark Well, 'learnt' and 'learned' are both acceptable in my previous comment above.. but depending on where you are from, one is more acceptable than the other.
when you drank cyanide i was like "hmm he knows what he is doing, he will be fine" but this, i just got the notification and when i saw the title i was like "WHAT THE HECK IS WRONG WITH YOU MAN"
What I mean is bacause it can be done it doesnt mean it should and there is no benefits of doing it at all. Even if nothing bad can happen to you there is no good reason to do it. I like most of what you do when I learn things but this here is like giving up to the show off era we are in these days.
Cody, watch Thunderf00t's videos on sodium. He has 10k-fps close-up high-speed videos of coulomb explosions. The worlds most detailed videos of coulomb explosions AFAIK
4:21 I love the little explosion just off screen, as you remain completely stone-faced and reiterate "yeah, I'd rather it not do _that_ in my mouth". :D
I gotta say, i've followed you for years, you're one of the most genuine people i've seen on youtube.. entertaining and just such a dork who enjoys doing your stuff, you've made me feel like going back to school... so keep doing it, it's really entertaining.
My science teacher's brother put a piece of sodium in his mouth when he was in high school and he burned the living hell out of his mouth but was fine. Von has told us the story at least six times.
Hey Cody, what if you dropped sodium/potassium metal into water in a vacuum? Since sodium reacts with water to produce sodium hydroxide and hydrogen gas. If there is no oxygen will it still burn/explode? Please try this! Thank you.
The little I understood from watching Thunderf00t's videos on the theme of alkaline metals reacting with water, it seems that the shape and "purity" of the part first touching the water can affect the explosion effect greatly. Since these are Coulomb explosions (although there are still some people denying that), there is a lot to learn about them yet and as Cody said, they are not fully understood. I recommend you to watch Thunderf00t's video series on the theme.
It would appear that the reaction actually heats the metal to it's melting point and possibly to a boiling point... once that happens, it's surface area to react with oxygen is greatly increased and hence the further explosions. But as pointed out, it's not a set science.
Why are these metals so reactive to water? It doesn't make sense like water is the most neutral thing on the earth but it causes metals to explode into flames!
As far as I know, the elements lithium, sodium and potassium are so reactive to water due to the fact that these elements have 1 valence electron. These electrons want to bind to other molecules very often and so when they're surrounded by something that will accept an electron, they react violently with it.
McSuperRoy it's from the hydrogen bonds in water I don't know much but water has hydrogen bonds and if anything happens with water it usually has something to do with hydrogen bonds
McSuperRoy it's pretty simple. As you know, water is H2O. Oxygen is one of the most electronegative atoms (next to flourine) because it has 6 electrons in its outer shell. When it can bond 2 electrons, its outer shell is full meaning a low energy state. In H2O, oxygen shares one electron with every Hydrogen, so all 3 atoms have noble gas configuration (meaning full outer shells) But hydrogen is more electronegative than sodium or other alkali metals. Akali metals only have one electron in their outer shell, so they really want to pass it away. So when you put sodium in h2o, the hydrogen molecules are replaced by sodium, so you get h2 and Na2O because this is a lower energy state then 2Na and H2O. The difference of energy levels is released into heat, this is why it explodes
Nitroschock Well said! Probably worth pointing out that it's this combination of released H2 (hydrogen gas) and heat that then ignites, just in case anyone missed that implied result.
What would happen if you took a piece of sodium about the size of a quarter and dripped one small drop of water on to it? Would it just fizz, or melt the sodium?
tye tygon It might be interesting, given how malleable potassium is he could make a pancake of it and drop water onto it, the exact opposite of the usual 'metal into water' videos.
Well done! What would happen if you release sodium or potassium at several meters depth as oppossed to dropping it onto the surface of water? Would the reaction be more violent as each part of metal that chips/explodes off then cannot escape contact with water? Or would the atmospheric pressure surrounding it contain more of the reaction? It would be interesting to see how it moves when totally submerged. I recently found your channel and it's awesome! Keep up the great work!
Honestly Thunderf00t is the man you need to talk to, but from what I've seen it doesnt really matter if its above or below the surface. There is some kind of electrical interaction that causes the explosion.
In your "Potassium and Sodium In a Vacuum" video, you demonstrated that potassium was much less reactive at low atmospheric pressure. Do you think you could step inside of a vacuum and take a bite of potassium, assuming you could put up with having the gasses violently ripped out of your body through your mouth and sphincter for a few seconds?
