I love how the egg rotates, as if the solution is trying to cook it evenly.
Stirbar in the beaker
there is a magnetic stirring bar.
@@byungkyup He's talking about at 2:00
@@SexyEarHair yeah---and the egg and the solution rotates because there is a magnetic stirring bar in the solution (watch carefully at the beginning, before solution becomes cloudy).
@@byungkyup Yes i know there was a stir bar. But the rotating he is talking about is explained at 2:00. Op was not talking about it just spinning around the glass, but rotating on its axis. Caused by the bubbles forming on the bottom of the egg and making it flip 180 degrees. Did you check the time stamp i posted or just commented without watching?
'Poached In Acid'-GREAT name for a death-metal song. \m/ Chemistry is brutal.
🥚🤟🏻💀🤟🏻🥚
"Piranha Solution" is my band's name!
My guess on the first experiment would be, that the calcium carbonate reacted with the sufluric acid forming a passive layer of calcium sulfate, but I'm wondering if the shell would still break at some point.
It's surprisingly unreactive toward quite a few things that it would seem it would just be able to tear into knowing nothing more than its propensity around organics.
If the heating becomes enough that the liquids inside turn into steam, then the egg might explode.
Let's just go ahead and indulge the organized crime viewing bloc with a comparison between the solubility of calcium carbonate and hydroxyapatite in piranha solution; including various ratios of H2SO4 to H2O2, temperatures, and agitation rates. Nile Red, are you listening???
Yes, I was also surprised that the shell didn't dissolve right away with very vigorous release of carbon dioxide -- your calcium sulfate passivation idea sounds like it might be right.
That would explain the slight amount of bubbling, since the resulting carbonic acid would decompose into water and carbon dioxides
I thought the piranha solution would have readily dissolved the calcium. It's always a pleasure to see these videos, thank you.
Maybe if you make whit excess sulfuric acid
@@gabrielbelouche3954 Calcium sulphate is really insoluble
Lol at niel's face with the egg.
Of COURSE Neil would evile grin whilst dropping egg into Piranha solution. Reminds of Christopher Lloyd playing Judge Doom in Roger Rabbit dissolving a toon in The Dip.
And people say he doesn't smile.
As a Frenchman and a chemistry lover, I approve this mix of chemistry & cuisine !
Et bon appétit bien sur ! :D
When he said not to eat the soft boiled egg. I felt like that was the one I'd definitely want to eat. 🤷
Well, cuisine is easy and (mostly) home safe chemistry!
@@davisdf3064 it looked perfectly cooked and none of the mixture got through to the egg. I don't see why not eat it?
@@rexmann1984
For safety reasons. Boiling an egg in Piranha solution isn't the most traditional way to do it, so we don't know if any of the acid got in the egg or any side effect of cooking it like that.
@@davisdf3064 well I guess *somebody* wants to live forever. 🙄
Speaking of mass transfer, the cracked egg reaction reminded me of a two-stage rocket powered by different fuels by the way it reacts differently first with the protein-heavy, runny whites and then consuming the dense, fatty yolk
yeah
It is always fun seeing The Chemical Stig enjoying his job!
It was interesting how the egg rotated in the solution from the bubbles @2:00
Macaroni does that too with ordinary water. How is that interesting?
The little physics going on in a chemical reaction. That what's interesting.
There's a stirbar in the beaker. You can catch it in the beginning.
Loved that part. It looked like it's getting a tan XD
@@MentoDaSheep lol
Great to see you back in your office and lab!
I was intrigued by the fact that the egg not only flipped over and over, but it also spun.
The magnet on the bottom of the beaker is spinning and that causes the liquid and also the egg spin, I think
@@duendemajito that was a magnet?
I’m mostly self taught with chemistry. Snuck out on the weekends to learn it in college. Thinking about taking O Chem for Fun. I absolutely loved it.
Thank you for these videos. They got me through Covid
ഞാൻ ആദ്യമായാണ് ഈ ചാനൽ കാണുന്നത്......amazing Innovative ideas ഈ ചാനൽ കണ്ടാൽ കുട്ടികൾക്ക് ഉണ്ടാകും.,....., ഒരുപാട് കുട്ടി ശാസ്ത്രജ്ഞന്മാർക് പ്രചോദനം നൽകുന്ന ചാനൽ.....Lot's of thanks.
Thank you professor and everyone
If you look at their first video this channel has posted back in 2008 around 13 years ago and this video you can see the guy with the curly hair looks much older now, obviously but it’s like you can go back in time
0:38
Neil definitely looks like a mad scientist who was trying to get the egg dissolved
I wish you would show more organic chemistry. Your Sarin video was fascinating. Maybe the ziegler natta catalyst mechanism would be interesting.
Most vicious destroying acid mixture:
Chicken: skeletonized
Egg: turns brown
That soft boiled egg looked delicious! Just the way I make mine...
Eggs are amazing, the strength of ostrich eggs is also insane.
Thank you Professor
As a chemical engineer I agree with this message
Absolutely interesting
And here I was hoping for an easy method to poach an egg without stringy bits

I'm not going to be able to sleep tonight
The best example of mass transport for me is iron in different forms being burnt in air. Rod, not much happens. Wire wool burns quite pleasantly. Iron filings go woosh.
Now let's add some aluminum filings!
Thank you all for such a fun video.
id like to see a Piranha in Piranha Solution!
🤣🤣🤣
You could identify as one ... and volunteer for the experiment? You know ... "for science"!
@@Muck006 you must identify as a candiru 🦈🐡🐟
Somebody call Nile Red!
It'll look a lot like the chicken leg and other room temp piranha demos.
If you just want to clean the bones off really quick, heat things up.
Either way you'll be left with mostly just the skeleton of the fish, its just a matter of how long you gotta wait lol
I thought that the egg tipping over might have been from the acid eating away at the egg a bit, and the part that was above the acid becoming top heavy so it tipped.
whoever suggested the egg is a genius, that was great! Sometimes you don't need the experiment to make sense, or have a goal. sometimes you just NEED to know what happens, just because! i'll bet there's plenty more things that could have interesting piranha solution reactions. What about a stalk of celery? Or something fatty like streaky bacon?
I remember a documentary, where they use acid to get rid of the white bits of mandarins to be tinned. (it's been 10-15 years ago, I can't remember what they used and what base to counter it after the process). this reminded me of it.
Another eggcellent video. :D
Ba dum tss
Off to the corner of shame with you!
I saw professor Poliakoff yesterday at Sainsbury's somehow we both looked at each other before I left
Shouldn't the concentrated H2SO4 desolve the shell and than attack the organic stuff in It ?
Labratories: Great place for learning, lousy place for breakfast.
Also, always use proper safety precautions. Do them inside the hood chamber. with the vent on Wear proper protective gear. Have proper mess-containment systems in place. Dispose of remaining chemicals in a safe manner. Do not do this on the kitchen counter. That's a *big* part of what I'm seeing here.
safety first, fun right after
No, a very interesting experiment. Thank you.
Would love to see what HF would do the egg shell!
Hello friend. Love your science. Could you do a feature on "Trinitite"? Many thanks....
This was cool, I didn’t expect that
I believe the egg flipped over each minute due to the solution eating away at the button. Kind of like a glacier flips when melting.
I think so too. It changed the density of the egg at the bottom and thus it turned. The bubbles must not be undervalued too
Always a great day when I see a new video posted on a channel worth it’s weight in gold!!
Thank you for sharing knowledge!
Such fun, I like a soft boiled egg.
Hey professor, could you make a video on the most violent solutions you've seen or made before, and maybe get an example if it's not too much?
The natural rotation every minute was cool, with the hard boiled egg.
The hard boiled egg ended up looking like the Eraserhead baby
Eggs have been around a lot longer than chickens have.
Sir please make a video on Cu2So4.
Copper I sulphate.
2:00 it's the dancing grape...errrr... egg experiment
Hrmmm. I would have thought that the cause for the differences in reaction would have more to do with reactivity.
The calcium structure of the shell nearly didn't ready at all.
The hard boiled egg blackened, but again didn't really react otherwise. And while there was oxidation, more reaction was made from bubble formation than anything else.
In the third test we see two separate periods of reactivity.
Is it not a case of the whites of eggs not having much oxidation?
With the raw whites acting like a skin? Then the rich yolk becoming exposed, allowing the reaction boiling everything into organic sludge?
Just curious, as I'm not a chemist.
They're both mostly made of proteins, so the reactivity by itself is hardly different between the two. It might have something to do with the shape of the molecules - in a hard boiled egg, the proteins are unwound and tightly interlinked (hence why it's hard), and in a raw egg they're much more compact and act like liquid. It takes additional energy to untangle the hard-boiled proteins, so the reaction is slower
Piranha is strange. It doesn't attack some things it would seem it would just go apeshit on. But when it finds something it likes, it will destroy it quickly.
I think the key is dehydration. If the sulfuric can't find "water" to pull out of something, it can't really break it down because the peroxide is kinda "just there". Basically, if sulfuric acid doesn't break something down on its own, piranha will struggle as well.
I know it's not quite that simple because of concepts like H2SO5 and such, but that's the basic pattern I see.
*1 week later*
NileRed: "Eating An Egg Boiled in Piranha Solution!"
I don't think that will happen... I mean he may do it... But we probably won't see it 🤣
@@MadScientist267 I'm very curious if it would actually be dangerous to eat or not. As long as the shell is intact, that is!
@@justice5150 I don't believe so, despite the idea of piranha being involved.
While the shell is permeable, there's a few things about this that stand in the way of it being much of an actual danger.
That said, I still wouldn't eat it, *just because* but that's mostly psychological (internally) and liability (lol) externally.
The major considerations are:
1. Hydrogen peroxide is the limiting reagent, as it is consumed first. This will be evident with any video that has shown piranha being regenerated by adding more peroxide (Nilered does this more than most). This would be the component to fear as far as internal consumption. As such it isn't going to want to stick around if there's sulfuric and a viable organic around.
2. Sulfuric acid in tiny quantities isn't really a big deal consumption wise. As long as it's dilute enough, not really a thing. I'm not saying it's "safe to consume sulfuric acid", just saying that in the right circumstances, it won't really do anything to you. What's managed to make it thru the shell in that period of time would be a pretty small amount.
3. The shell is made of calcium carbonate, which when attacked by the sulfuric, becomes calcium sulfate, which has no interest in water. This passivates the carbonate, protecting it from further erosion. This means only the porous aspect of the shell can allow any passage of liquid at all since the shell as a whole doesn't get breached, which while it will happen eventually, is a pretty slow process.
There's also another membrane just on the inside of the shell that slows this movement down even further.
Basically, "Peroxide can't really get in there, and any that does, will be trace and/or largely break down before you can clean up and consume the egg, and the little bit of sulfuric that makes it anywhere, after a little cleaning ("dilution"), wouldn't really mean much."
It'll probably taste pretty nasty... But that's about it.
That said, I still wouldn't do it. Like I said. Just because 🤣
I thought this was an Ordinary Sausage video
Awesome.
Hm. So it sounds like if a thing is more wet(ish) it reacts more easily & violently...
What if you put in a piece of dry meat like jerky, or dehydrated/freezedried meat?
I would like to see what the inside of hard-boiled egg looked like after being in the solution.
3:10 the forbidden coca-cola
Love the nails
Thanks 😊
I was quite surprised that solution could not penetrate the shell since I was always told that shell is porous (explanation given that so embryo can breathe).
Suppose pores are too small for solution to pass through
What concentration of sulfuric acid was used? The pirahana solutions on this channel seem much less reactive than ones I’ve seen in other videos. I wonder why.
bro that guy's face and voice is literally "generic evil scientist"
Thanks for another great video!
Neat!
Now I wonder. What would react with an egg shell faster, concentrated sulphuric acid or (slightly) diluted sulphuric acid?
I don't know for sure! It might be like copper and nitric acid, where the concentrated stuff forms an oxide layer, and the dilute stuff dissolves said oxide layer so it can continue to attack the metal.
I don't think it would matter in this case, likely is passivating
@@MadScientist267 aluminium passivates in concentrated acids but doesn't in diluted ones, it could happen the same with the CaCO3. However as someone else said, HCl is much more effective because it forms CaCl2 (soluble in water and quite stable)
@@martinguarani4573 The key to passivation is lack of solubility
@@MadScientist267 Sure, but the cohesion of the non soluble salt layer is also an important factor. If there are cracks in this later the acid can still reach the metal (or whatever) and keep attacking it. This is what happens with iron rust for example, and it might be similar with aluminum in diluted acid
I'm sobbing
"You know that sulfuric acid that burned John's finger black, so it had to be amputated? "
" Yes, that was a horrible incident... what are you implying?"
" ...nothing... just... let's mix it with rocket fuel!!!"
"... this is a horrible idea... let's do it! "
I would like to see the experiment done again, but with a hole in the egg.
New video!
You can use that overturning egg as a clock.
EGG TIMER
Came for the acid, stayed for piranha soln.
Couldn't we add a little bit of HCl in the piranha solution?
What about adding hydrogen peroxide in aqua regia?
Isn't just NaOH more effective at dissolving flesh?
This, ladies and gentlemen, is precisely why you need to chew your food very well
Now we just need to try and cook some rice with the piranha solution and we can make Oyakodon: Chemical Pirahna Style
Also, I think the browning of the boiled egg in the second run was it being turned into a century egg
I imagine chemical engineers in the US Boston area are especially familiar with Mass. transport.
Wow, that was really eggciting!
What would happen if in the first egg you poked a small hole in the shell before lowering it into the piranha? Would the reaction attack the inside and eventually eat the entire shell, or would you just be left with an empty shell?
If the question was phased " which came first , the chicken or the chicken egg ?" You'd be right , but then it also wouldn't be a riddle.
Is there a reaction you could put an egg in that would cook it in its shell and still be edible? If the pihrana solution can't make it through the shell could you eat the one in the video if you washed it?
This isn’t how you’re supposed to do it?
mad scientist Neil
What came first the chicken or the egg? It’s the egg 100%. There were eggs long before there was ever an animal we’d call a chicken
I was thinking if adding more hydrogen peroxide would help. And also if it would clear up the final black one.
I now find myself wondering what would happen if you cut the hard boiled egg in half before putting it in the solution. Would the hard-boiled yolk react significantly differently to the piranha solution than the hard boiled whites did?
What happens if you put a few toothpicks into a hardboiled egg or pierce the hardboiled egg many times with a fine needle?
These chemists got raw eggs, and instead of BOILING and PEELING the eggs, they decided to buy hard boiled eggs from the grocery story
pretty intense reaction. That's my scrambled egg recipe.
what happens if you dissolve the shell with something else and then put the egg held only by its membrane in a milder piranha solution?

What about fullerenes in h2so5?
It looks like you've discovered how to make egg-based dark ale.
Is it possible that the shelled hard-cooked egg was spinning because the piranha solution was honing off the surface of the egg? If that's what was happening, the egg would roll over when the part above the surface of the liquid was heavier than the part under it.
This experiment means that to get a right product mixing well of the reactant with each other is necessary.
Am l correct 💯🤔🤔
0:24 what came first, the egg or the chicken?
It's the chicken. Boom. It's all in the delivery.
thought this was a nile red video for a second lol
Would different animal eggs react the same?
@@Paonporteur even fish eggs?
What do you do with all your chemicals when you are done using them? I don’t imagine you can just pour them all down the sink?
fun fact: the ocean is Nature's bin
What would happen if you add sugar syrop to the solution?
Lol better be standing back 🤣
Such a charming fellow. I would have him stay for tea one time
2:37 whenever I try and make eggs in the microwave...
Have you tried any of these experiments with HEATED piranha solution? I don't mean self-heated, I mean externally heated, and maintained at a high temperature.
