'can't you just hear the electrons thanking me'. Salt proceeds to spell out RIP (9:09)
Nice catch ;)
thanks for the catch, i actually missed it 😂
So I was not the only one to notice that XD
goddamn
Wow! Nice catch!!
Props to him for releasing the electrons after they were inprisoned for years.
Only to condemn them to being awkwardly confined in chloride ion orbitals.
Mmm. Just one orbital to another though... I was sad for the loss, then RIP happened. Sucks to be the electron right now, maybe, have to ask them
But they aren’t imprisoned. They’re entangle with free electrons. No electron has an identity.
I have lots of flash drives literally trapping electrons in their wells for years
Being as elections move at the speed of light or close to. Time dilation would make it only a moment trapped in the electrons time.
Even salt prison uniform is orange!

@@MustachedEmu "That's my secret... I'm a pretty cool guy."
"See that's me Smashing. Cool.
So, you're probably wondering, How did I turn green?
Well, when you eat irradiated 🧂, the physical changes your body experiences are quantified by...." 😂 I can clearly see how this video would go. I was thinking, how's he going to discern the salt all over his table now from the regular salt?What would happen if he ate it? You answered perfectly 😂
Actual LOL! :D
French physicist here: "de Broglie" is actually pronounced something like "broil". Even for French people, the spelling does not give any clues to the actual pronunciation. The de Broglie are an old nobility family who basically made up how their name should sound like.
In any case, amazing demo coupling thermoluminescence to the wave-particle duality. Excellent work!
Just call him Sir Broccoli.
Yeah, I heard that he postulated this thing in his doctoral thesis and then had no other contributions to science after that, even though he could had just ran with it and develop the whole quantum theory himself. Or at least wave mechanics.
I would argue that it should sound more like "broi" (pronouncing it in english) since the "L" is not pronounced
In India we were taught to pronounce " Dee brog lee" or " De Broy" ...
here in indonesia they told us it was pronounced balor....
That's one of the coolest chemistry demonstrations I've ever seen.
I'd say it's more physics than chemistry
Agreed!
A box? Pathetic! I can hold an electron in the palm of my hand!!!!!
Or can you 🧐
*typical Vsauce glare intensifies*
In fact I'm holding millions of them right now
but u didn't trap it lol
I hold neutrons, which is why "Now I am become death, the destroyer of worlds."
@@decreasing_entropy3003 weren't you holding neutrons from forever in your hands
Ohhh the prophecy have came the death destroyer of all is born
Those electrons were dying, instead of being freed at 9:13 when they proceed to glow with their last breath "r.i.p". What a fantastic coincidence.
_"Can't you just hear the electrons thanking me for releasing them from their prison"_ - and enslaving them to the eternal servitude of a Chlorine ion? I don't think so.
🤣
Nah. Chlorine has a very loose attitude towards its "Servants".😂
So it got married?
Its a new house so change prisons
If you dissolved the salt in water, would it also release the electrons? If it does would it show as light or no, because you're not providing enough energy.
wondering the same, drop it in water
Good question mate
I asked the same and then found your ask.
I don't think the heat energy is important as the electrons exist in a quantum level so the same energy should be released however the electrons are untrapped... I think!
The orange color is because the electrons can CHANGE their energy, by going from one mode or state to another one. As he says, they absorb blue light, leaving the orange for us to see.
If you dissolve the salt in water, the available modes or states are all different.
There must be a positive ion somewhere. He mentioned a Cl2, but no positive ion. Must be a Na+ somewhere.
That was one of the coolest demonstrations ever! In physics we studied the “particle in a box” as an idealization but never thought there was an actual application.
On the flip side, when you heated the salt, I think you were demonstrating the effect of quantum tunneling! So cool!
Quantum tunnelling? I thought that was incredibly rare or is that only on the macroscopic level?
@@sprightlyrandom1550Depends on the amount of tunneling.
If the region of space to go through where the potential hill is higher than the energy of the particle, is very thin, and the degree to which the hill exceeds the energy of the thing is rather small, then, shouldn’t be especially uncommon, I think?
@@sprightlyrandom1550it depends on the system of course. you don't need to go too deep into physics or math to be able to solve Schrodinger's equation for a particle in a finite potential well - if you do that, you'll find that there's actually a nonzero probability that the particle's position is measured outside of the potential well even though its energy is lower than the potential. this is quantum tunneling of course. if i remember correctly the solution is parameterized by the width of the well, the potential, and a single quantum number (in 1d). you can probably find it online
Excellent presentation.
This vindicates those mandatory "particle in a box" exercises we all solved in freshman physics.
This guy is gonna end up casually making a demon core someday
He will show us how!
@pyropulseIXXI ...what?
the demon core was just a bunch of specific radioactive material in a ball shape. it's not very difficult to make, just expensive to get this material.
Uh... i was joking guys, theres no need to fact check it
Who wouldn't want to?
You could literally show this to a 6 year old and tell them, in a way, that this is magic/fairy dust. Explain it to them and get them interested in the lab early on in life!

"can't you just hear the electrons thanking me for releasing them from their prison". Your videos might be short but easy to understand. Thank you so much.
Great stuff, I’m 36 and still feel like a kid sometimes watching your videos enthralled with learning new things.
9:12 THE SALT SPELLED OUT "RIP" LMAO
4:15 Cobalt-60 is no joke: metal rods of Cobalt-60 usually contain a marking "drop & run", because the amount of radiation it releases is fatal within seconds.

This was one of my fav videos. You very skillfully mixed theory and practice in a very practical way. Its brilliant. Youve made the complex seemingly less so without loosing any integrity of the real science behind it. Thats not easy to do with this topic. Thanks!
Now repeat this experiment near a cloud chamber to check if the electrons are visible
I would have thought that the released electron would interact with the nearest Chlorine ion so unlikely that you would spot any released electrons outside of the salt.
Most will still be stuck inside salt probably, but I wouldn't be surprised if some did manage to escape
Their energy is far too low, a cloud chamber track a thousands of ionized molecules, and these electron can’t even escape their sodium box.
You are very VERY smart.
I'm really glad you are helping teach people & testing out expensive lab setups for us poorfolk instead of becoming a gruntled scientist/substance abuser.
I saw a recent chemistry discovery that trapped an electron in a chemical bond (cubane?).
For your video on forbidden particle transitions (glow paint), I made a lampshade painted in the stuff trying to figure out how photon "batteries" work. It was a 200$ test so thank you for investing SO much into your equipment and supplies ANND SHOWING IT!!
*(warning possible stupid idea ahead) : Your video on entropy recently made me wonder if the light slit experiment is actually us 3D beings seeing a 4D phenomenon. Time travel seems very hard but so does grasping the concept of the dual particle/wave light photon stuff. let alone UV rays exciting photon energy levels so they can be stored for the future in plants.
"yep, tastes like salt"
"those are nuclear reactor levels, so its far beyond lethal dose to humans"
man, this guy sacrificed himself to give us the taste test
he also mentioned after the salt itself isnt radioactive. but still sounds funny
He isn"t human.
@@Fvhvygyty323 Not anymore.
maybe this is the beginning of cooking recipes, involving irradiated salt, bananas (for neutrinos), and heavy water. I'm sure there's some unexpected result you could get from D2O, maybe in baking?
@@mcpr5971 except from a slightly sweeter taste, I would say no. Chemical properties of D2O are different enough to influence proteins and cellular chemistry in high concentrations, but not that different that "normal" chemical processes should show significant effects.
Fascinating. Potassium chloride also changes color (from white to purple-brown) when irradiated with an electron beam, and was once used as the phosphor coating in special-purpose CRTs that would retain an image for a long time even after being turned off.
Such a substance is known as a scotophore or dark-trace phosphor, and the tubes were used in scientific apparatus to record data prior to the advent of digital storage. They would retain the displayed image for quite a long time (weeks or months) unless "erased" with heat or infrared light, giving plenty of time to analyse the data or simply photograph the image itself for later analysis.
4:17 "The reason it gets its color is because it's been _blasted_ with gamma rays"
That explains the Hulk, no?
Ah, the famous orange Hulk! :D
@@mytube001 Different substances have different colors.
There is one! @@mytube001
Quantum physics is more like an unpredictable thing because it works at real time, is affected by even the smallest disturbance of any variable and changes if you look "harder" but all it ends up being is counting every grain of sand vs weighing the whole beach at once
Nice videos, wish you to find better advetiser
flashbacks to solving Schrodinger's equation for a particle in a cubic potential well in class. physics is great man
Wait until he finds out that the electron might be found outside the box.
Dude… your genius is beyond comprehension ❤
I can hide a bunch of electrons inside a quark. Inside joke, I guess.
When it all matches and works perfectly from what the equations tells us, THAT FEELING 😭
In double slit experiment how it became possible to hit only one electron bombarded
What do you mean? I don't understand your question.
Another really cool real world example of an electron in a box is in conjugated poly-enes! Essentially, the conjugated pi system acts as a box that traps an electron. As the conjugated system gets longer, similarly, there are more accessible energy levels. That might be a cool follow-up video to this one :)

Its got an orange vibe because it is indifferent to other colours.
This is a beautiful experimental demonstration of the 'Particle in a Box' problem in Quantum Mechanics that is taken up as a first problem. It's a fine example of theory and experimentation going hand in hand, which is absolutely crucial for real science.

‘de Broaglee-yay’! Louis de Broglie has been a major figure in the development of quantum mechanics for very nearly a hundred years. Isn’t that time enough to find out how his name is pronounced?
He's uncertain
🤦♂
To be fair the proper pronounciation is nonsensical
The origin of the name is Italian and the French just made up a non phonetic pronunciation, because, well, that's a French thing.
Hey. Just a question you might be able to make a video about. So, if there's a room connected to another room and both had the lights off, but then in room one you turn the light on. Now, here's the question. Is room two brighter or darker? It's brighter because more light is coming in, but it's darker because there's less darkness around it, so it seems to be darker. This is just a question I've been wondering about because I have a bathroom connected to my bedroom, so I experience it every day, and I think the concept is just really cool.
So basically, if the therapist isn’t telling you what you want to hear, just change it. sorry, but that doesn’t sound helpful to me.
THAT'S what you took from the video?
So pick a therapist and stick with them forever regardless of how well it's working out.
See how dumb that might be?
There are a number of reasons it might be beneficial to switch up therapists. I had one once who talked in lengthy lectures; I left many sessions feeling unheard. Another would cancel too often. And sometimes one gives advice that doesn’t feel helpful.

This is the first time I've ever had a reasonable explanation for why particles are wave like. That's nuts. Thank you
now let's wait until michelin star restaurants watch this video.. 😂
Man, thanks for this video. During my "studies" of Quantum Physics, I always went through the wave function part where you calculate the wave function of a particle in a box and wondered how the Frack you trap an electron in a box...
You should go to the channel Theoria Apophasis, this guy is an atomist.
" Quantum" Physicists are charlatans.
An "electron" is not a thing it is a unit of measurement.
If the resonant frequency of the trapped electron is blue, why does it radiate orange light under heating? Is it because the electron takes the blue light equivalent of energy from the hot plate to ‘escape’ the box and therefore radiates the excess energy as orange light(white-blue)?
As I understand it the absorbed blue color corresponds to the jump from box-level-0 up to box-level-1. The emitted color corresponds to the jump from box-level-0 down to the unbound state. They are different transitions, and it's a coincidence that they show similar colors.
...Ooooooh! You said Trapping an *ELECTRON* in a Box . OK.
Sorry brotha my mind was in the gutter . I thought you said ... have a nice night everyone!
electrons aren't exactly 'whizzing around' in electrical wires. Their speed is at most a few meters per minute. Charge moves at near light speed, not the electrons themselves.
Best Action Lab video ever
Stopping kids from saying first on this reply
way to make quantum dynamics so whimsical
Can the experiment be done successfully if the salt will be irradiated with an E-beam accelerator?
What is the needed energy?
Now I want some kind of futuristic lava lamp replacement that somehow cycles salt through a gamma source, then at some heated transparent surface, and then back to the gamma source. I could watch that effect for hours. Great video! ( :
Light is not a particle, not a wave.
It's just the instant of creation of space.

Action Lab- "This has been blasted with 3k rads of gamma radiation" *proceeds to eat some*
Me- 😲
"Yep, tastes like salt!"
Of course. Everything would taste like itself... whatever version or condition of itself it is at the moment.
That's very cool! So, presumably some gemstones that are treated with radiation to change their color, are not actually radioactive afterward due to transmutation, but change their color due to these displaced atoms. So if you heat up those gemstones, the heat will restore their original color.
This is the one of the coolest videos you have done, man this channel is great. Seeing that salt light up was awesome, this physics in action. Also, at the end of the video, "as the electrons are released from their prison where they've been trapped for years. Can't you just hear the electrons thanking me for freeing them from their eternal prison" this is hilarious.
One of the most poetic physical experiments I have ever seen ❤
i love the irradiated salt experiment. one of the only things i remember from high school lol
How much energy is being stored? Possible battery idea?
This is just pure magic!
Hi @theactionlab, when I heard this explanation I thought of a question: when you say that raising the energy results in more “nodes” Could it imply a theoretical upper limit to energy levels in quantum systems, implying a maximum number of nodes and supporting the idea of a quantized universe at small scales, similar to concepts in Loop Quantum Gravity?
Middle school refreshed and expanded!
That looks truly magical.
Leaning into this further, it’s these quantized discrete energy levels combined with wave-particle duality that is one of the fundamental paradigms of QM/QFT and how we can for instance extend and combine maxwells equations (classical), the Standard Model (QM) and special relativity to arrive at QED, or explain the discrete probabilistic spatial distribution of the electron orbitals/principal energy levels.
At the end of the video, the lightened salt looks like “RIP” 😅
