Gallium (beating heart) - Periodic Table of Videos

[ZTEiffel65]

Neil looks like a nazi germany chemist.

[Rdtackle82]

He would have a good relation with Gammy Num Nums

[blackboo28]

he sounds like salad fingers lols

[Doddmond]

What's the Uranium and Gallium compound called? Can't find it on wikipedia.

[mysticblue12241]

That heart has some severe arrhythmia problems.

[Level84]

@mysticblue12241 lol

[jbeer82]

mp of Caesium is 28.44 C, bp 671C and Gallium mp 29.74C, boiling point of 2204 C

[GahSoonChan]

is the sound just part of the fx? and where can i buy gallium in bulk?

[gabrielabalayan]

@GahSoonChan gallium costs a lot :P

[GracefulValley]

It's... ALIVE!

Seriously, I love these videos ^^

[marcusduck]

You could melt that piece of metal with your hands? Cool..... I want a knife made out of Gallium so that I could squeeze the blade and melt it with my hands.

[1jake312]

@marcusduck thats how psychics melt forks...i think...it's my conspiracy :0

[Hashishin13]

@1jake312 I've seen something on that too, they warm the little bit that connects the cup part of the spoon to the handle then shake the spoon a lot.

[mattrules161]

It comes from the chemistry and is lost as heat via waves

[itabiritomg]

i have a quest: when the "gallium heart" beats where does the energy of the motion comes from and where does it go then?

[djmussy18]

@itabiritomg awesome question......i was wondering the same, ask that on yahoo answers so i can look it up.......thnx

[djmussy18]

@itabiritomg oh no actually now that i thought about it, just my best guess....it might be the pressure outside gallium, the atmospheric pressure and within the solution which is acid diluted in H2O...am sure there is a better answer, but that can give you an idea....

[donatgashi2]

does really sound like that

[knifemakejake]

would it be possible to handle gallium sulfate? might be even closer to mercury in properties.

[thekingsora]

could you guys PLZ PLZ PLZ do a video just of neal plz

[galliumguy74]

Hi!! I'm galliumguy! I do have a nice chunk of gallium in my collection.

[kinstar]

if science was like this in sku i would av paid more attention lol

[colder47]

the man has that awesome hairstyle

[BelialAndar]

You can take a bit of iron and put it next to the Gallium, Making the this process happen at a faster rate.

[bubblemuffinxp]

that dude needs a hair cut...

[Johnsavag]

I don't understand why you use an oxidizing agent. Wouldn't you want to reduce the gallium sulfate?

[DeanMalenko]

if you have a sufficient amount of gallium just above the melting point and you put your hand in.. does it feel "wet" ? how is the feeling compared to putting your hand in water of the same temperature?

[odysseus9672]

Wait, that means France has two elements named after it? We should change the name of Francium to Chinium or Japanium or something. :p

[NathnaelShenkute]

I thought gallium was very toxic

[Ryanlauph]

@NathnaelShenkute Nope.

[NathnaelShenkute]

@Ryanlauph thanks now I know

[sackgrinder]

the last chemist is the best. "I'm gonna be in a film. Give me the Pauly D blowout!"

[chankyplazma]

What things are made of gallium?

[elichannn]

@chankyplazma The blue laser that makes BluRay reader are made of gallium nitrade! :)

[ML424wr]

Free energy?

[indalcecio]

@ML424wr Chemical energy

[njskiinglegend]

I love these videos

[bbawor]

Really useful, thanks:)

[lp6702sv]

LOVE the giant hair



[fisterB]

Big Hair Day.

[appmanga]

Doesn't the gray haired dude play on "Robot Chicken"?

[skydark]

But how does all of this combine with the Flux capacitor?

[outrageousxolii]

Could anyone explain to me why the gallium goes back to its original state in this reaction? I understand why it flattens, but what exactly causes it to tense up again? Any explanation would be greatly appreciated.

[Aydosh1991]

@outrageousxolii I am not a chemist, but I think of it this way. The surface tension breaks down so the Gallium relaxes (just like putting washing up liquid into a bowl of oily water, the oils disperse). Next the chemical reaction causes the surface tension to increase again so the Gallium draws itself in (just as if the washing up liquid could be removed from the oily water, the oils would come back together again). If the right amount of dichromate s added, the reaction will repeat itself.

[Greeblimus]

@outrageousxolii There's still Sulphuric Acid reacting with it after it flattens, so more sulphate's formed adn makes it tense up again.

[stevieisbored]

heimerdinger 1:24

[joeboej]

LOOK ITS ALBERT

[stoopkitty2]

hair??? are you serious???

[juanster555]

So what chemical elements are in let's say.....Bread?!

[wookidoo]

@juanster555 From the top of my head: hydrogen, carbon, nitrogen, oxygen, sodium, magnesium, sulfur, chlorine, calcium, iron and cobalt are most definitely in bread, but you could probably find traces of about as many more elements!

[bluedeoxys]

Where do you get gallium

[wookidoo]

@bluedeoxys Gallium is found in trace amounts in the ores of aluminium and zink (bauxite and sphalerite respectively) and so it comes as a by-product from producing these metals. It's more common in bauxite than sphalerite.

[bluedeoxys]

@wookidoo I wanted to know where to buy it.

[AZNFlipy12]

3:48

WOW did you see that?

YEAH I DID...what happened...

[Kriticsify]

0:45

"Many years ago, a ph...ph (Looks at script*) professer bet me a 100 pound and when a 100 pound is alot of meneh that the melting point of gallium was lower of that ??????"

[bennemann]

@Kriticsify Was lower than that of Caesium (pronounced See-zee-um). It says so in the subtitles if you turn it on.

But the professor would actually have lost the bet according to Wikipedia! Gallium melts at 29 degrees Celsius and Caesium at 28 degrees. And they couldn't test it in practice: Caesium forms Hydrogen gas in contact with any water, and the heat from the reaction ignites the Hydrogen. If he tried to melt Caesium in his hand (which is naturally moist) he'd get quite the burn!

[u0leeeee]

@bennemann no he would have one the bet. the other prof claimed it was Ga was lower than Cs, and Prof. Bighair hair said its the other way round, which it is.

[u0leeeee]

@u0leeeee won*

[GaminOnly]

his hair....

[RoderickGubla]

When gallium is naked, it's flat and wets the surface ;)

[1997xander]

@RoderickGubla Your icon fits well with your comment.

[SineCosineNG]

I'm surprised they didn't mention that despite gallium melting at a low temperature, it is quite hard when solid. That, to me, is the most interesting thing about it, seeing as you can mold and remold it in a matter of minutes into whatever shape you want.

[IBingoBingoI]

Einstein is alive!!

[drainmudvayne27]

i thought albert einstein was dead?

[blueduderanch]

professor nipple! 1:20

[Delta8559272]

what is an amalgam?

[bsangoz]

does it make that sound or did you just add that in?

[TayTayJewel]

8 people bet 100 pounds that the melting point of gallium is lower than that of cesium.

[vigi86]

brit english is so funny... ^^

[Cajkesuzabava]

Oh how exciting! i think my pants fell off.... -.-

[Elprede]

You need 20gm to make a spoon of gallium.

About 54.62USD

[FiliPinoy95]

the chubby guy makes the best demonstrations!

[normahS]

This is THE most stereotype of a professor ever! Stay this way, you're cool! Or... well, it's cool that you're not... or well, you're so un-cool that you appear on the other side of tha cool-scale again and becomes cool!

[BigTex541]

40-60°C = 104-140°F

[TheLethaxx]

40 50 60 70 80 90 100 degrees c

[MrGWSprague]

No, its not expensive.

[altosax1st]

I thought amalgams were compounds of mercury with other metals

[IWishIwasAScreamer]

"when its naked it wets the surface......when it forms galium sulfate it pulls itself into a nice proud ball"---ermmm unnceccicary amount of innuendo lol :L

[metubegirl69er]

lol no one is goin to talk about 0:54 lol

[Shan23Studios]

Good Video, very instructive, but at the end how can we be sure that Ga+U union really never existed on earth? It was a good moment anyway. Good work.

[tacoyum6]

OUTraged!

[hshop4pink1]

Why does Neil always look so unimpressed by everything in the lab?

[mikkopaukkonen]

@hshop4pink1 Because he knows he has to clean up the mess afterwards. :D

[adriploma1]

Ceasium and robudium are my fovorite xD

[red666111]

gallium is my favorite element =}

[Vitaliy711]

Thumbs up if you love the professor's hand movements!

[bladit]

It's the same guy people! The first part of the video shows him fucking around with gallium.

"Oh yeah look at me. I'm melting toxic substances on my skin."

"Ooooh look, Acid!" And the "other guy" shows what happened to him afterwards. Don't mess with Gallium

[DreiHundertftw]

stereotypical mad scientist is stereotypical

[Kevintb10]

BAHAHAHAH THAT GUYS HAIR LOLOLOL

[amcnulty93]

Einstein wannabe

[applefan236]

you should have used the water and acid to melt the galium instead of your hand

[kozodlak]

Which dichromate are they using?

[pyropakman]

@kozodlak: Potassium.

[beruman]

the professor sure has the mad scientist hairdo. sooo cool.

[natemcgraw]

does the point at which metals become red hot (glowing red from heat) stay the same for all metals? the reason i ask is that some metals will become red hot without melting and the gallium turned liquid in his hand and stayed silver.

[verzinker]

@natemcgraw glowing red, for all metalls approximately 700 to 800 °C.

[GRAHAMAUS]

@natemcgraw the redness is dependent on temperature, not on melting point. Steel will glow red hot at around 900°C and so will any metal if it's still solid or liquid at that temperature. Gallium melts at around 30°C so even though it's liquid it's not red hot.

[WackoKillerDan]

The guy on 0:56 is a hardcore scientist. Just look at his hair!

[wyliexc]

its metal mario!!!

[QcTechs]

No gallium, no blu-ray.

It's used in 405nm laser diodes. Saying it's useless is ridiculous.

[behnamasid]

Gallium life form,

[IPKRubbish]

Gallium Oxide is in a liquid form.

[IPKRubbish]

Gallium is not magnetic.

[UNOnumb]

Are gallium magnetic metal as a simple steal . Does its reacts width magnet ? I am looking for not toxic liquid metal who have same magnetic characteristics as simple steel.

Anyone know does gallium magnetic ?

I searched gallium reaction width magnet over youtube but not found.

[IForgotMyDeodorant]

As a chemist student this 6:17 is very inspiring :)

[kikilosabeyno]

did edgar alan poe knew gallium beating heart?

[MrKaddan]

Does gallium oxidize if you pour it around in liquid form?

[DaBearsManiac]

did anybody else think of the terminator when the gallium moved?

[killernat]

make a soup spoon out of gallium to prank your friends and family (it melts in the soup) learned that from popular science

[Sheggy6626]

WOW!!!

[enflame117]

is Gallium poisonous? because i got a bit scared when you were mixing it in your hand.

[farfa15]

@enflame117 Gallium is nontoxic.

[simmyfake]

I thought its poisonous to touch the metal like mercury is

[JacksonDivilBiss]

@simmyfake its not

[Blackdragon595]

@simmyfake Its not really the element on it own that is harmfull; it's the salts of mercury that are.

[1RadicalOne]

Did you add sound effects to the experiment, or is that thumping noise really being produced?

[Xenophanessmith]

he has a cool fro

[nickgor12]

wgere could i get some pure

gallium

[Oxstayne]

I though Ga was a compound not a element.

[imaball]

could you do this to murcery?

[nickgor12]

so is gallium a toxic metalic liquid or harmless?

[miesrah12]

harmless

[DIRECTHALO666]

so is gallium also woods metal? or is it different?

[AssemblerGuy]

@DIRECTHALO666 Woods metal is an alloy, or a "mix", of some other elemental metals -- go look it up on Wikipedia to get the juicy details...

[DIRECTHALO666]

@AssemblerGuy - ya thanks but i already learned the difference from my chemistry teacher.

[TheJohnnyMetal]

so if I was to keep the gallium in there for a month, it would still beat?

[douro20]

Galinstan, a eutectic alloy of gallium, indium and tin, is used as a substitute for mercury in fever thermometers, an application patented by Geratherm AG. The only problem is that gallium very readily wets glass, so the inside of the glass has to be coated with an extremely thin coating of gallium.

[DarksporkLeader]

It's not perpetual motion. It's the result of a series of chemical reactions. At some point, the reaction will stop.

[freakman420]

@DarksporkLeader a better question would be, how efficient would it be with power output, verses power input. but since its such a new discovery... we won't know if its practical for a long time

[painxtreme]

@DarksporkLeader Yup, every system has its entropy.

[sailtheseaofcheese]

didnt medeleev call it eka-silicon? not eka aluminium. correct me if im wrong

[darmok1701]

You're wrong. Eka-silicon was germanium. Eka-aluminum is gallium.

[LePeintreOrageux]

IT'S ALIIIIIIVE

[chao129]

Could you try the mercury beating heart reaction? It works much better.

[r0galik]

3:78 test

[joouyang]

Now i learn something...

[niiidar]

The beat sound was annoying.

[Airsofter1995]

gallium is really expensive, 2KG is about 3000 dollars

[TuneMaestro]

@Airsofter1995 $1.50/gram. Not cheap,but it could be worse!

[ZuKahta]

@Airsofter1995 what are you going to do with 2 KG?

[PissOutMyAssBarf]

@Airsofter1995

Ive seen sites selling it for half that price. Still more than id want to pay though...

[NagaJolokiafied]

@Airsofter1995 I wanted some gallium so when i went on line to buy some, but i saw how much when i saw how much a few grams of it cost i changed my mind.

[o0SkateOrDie0o]

@Airsofter1995 So its still cheaper than weed in most countries

[Airsofter1995]

@o0SkateOrDie0o Yeah, weed is like 20000 dollars for 2kg where i live ^^

[tylerwalker2]

@Airsofter1995 O_O

[MrCoreyybee]

@Airsofter1995 its a good job it's light then isn't it ;)

[macro312]

@Airsofter1995

LIES!

[themassau]

@Airsofter1995 eb hapopy they use Silicon for semiconductors and not gallium-arsenide

[tiggerjayeward]

@Airsofter1995 one word: ebay :P

[StormRisingOriginal]

The bald guy in the gray shirt look extremely board. lol

[ignilc]

I think that he wanted to do the talking instead of the fat guy

[Chi7es]

the bald guy isnt bored, he just gotta go pee REEALY BADLY

[OrganicWebhead]

excellent video, and now i'm curious about this new "UGa" =)

[davewatcher]

Galluraniumate?

[SuperDuperMan180]

NO! THE POOR GALLIUM!

[Draxis32]

Some interesting prank to do with Gallium is to make a galiium spoon.Than you give the gallium spoon for someone to mix her tea or coffe, then the spoon will melt and the person will go like "What the hell!".

[AssemblerGuy]

@Draxis32 My arabic neighbours once offered me a taste of arabic coffee (that stuff is about as strong as rocket fuel) -- I should have suggested this prank for the next time they had someone over for coffee, who aren't acquainted with the arab coffee taste... XD

[Draxis32]

Yeah, well sadly its a little bit of an expensive prank since gallium is expensive and i don't have a clue where to find a place to craft a spoon, but maybe keymakers might help if you find enough gallium.

By the way, well, you know that arabic coffe is just boiled water mixtured with coffe powder, no filtration, no milk, no nothing, yeah I've seen it, it sure is strong!

[prfctday]

congrats Steve! you created something that never existed before! so cool. I wonder what this new material can be used for, if anything yet?

[matthew623210]

What are the measurements you used?

[Eithias]

lol people like you need to be put to death, you dont try to force your religion on others.

[seanarrative]

I have a question.

how long does the Gallium Beating Heart last?

5/5, cool!

[johnclavis]

Great video -- keep it up!

According to Emsley's "Nature's Building Blocks", the discoverer of gallium also named it that because his name was "Le Coq", which means "the rooster" in French, and "Gallus" means "rooster" in Latin (and the Gallic Rooster is/was a longstanding symbol of France). So he kinda snuck his name into the periodic table, that clever bastard!

[SomeLazyDr]

Isn't it a bit ironic? I love the irony in this video! From a stance of "eh, a boring metal" to "holy hell, I''m the first person to discover a new bond!" (Two different people, but at the same campus and helping the same production crue!) I absolutely love it!

See, now if you can go back and revise all those "boring" elements, you'll make something new :p.

[hugohugo37]

I can't stop watching these videos. Thanks guys (and girl in one video.) If it were up to me, I'd give you all 13-metal medals.

[ridelo]

I remember a lookalike experiment with mercury in stead of gallium. But you had to touch the mercury drop with an iron needle in order to make it beat. But when it started beating the frequency was a lot higher.
