I'd love to see the reaction with a high speed camera of today Higher speed camera!
Comment from : @spookayitsme

I would think that there's a discrepancy in this law If it was done with malicious intent, or to make a statement of such

How is white phosphorus not reacting with air?
Comment from : @dmitryk2891

Hehehe I did this on my channel And it is loud Extremely loud
Comment from : @AllChemystery

I'm glad University money was not spent on the coin I failed to enjoy the video because I was worried I'd have to report the whole Periodic Videos team for malfeasance
Comment from : @77thTrombone

In short, don't use a hammer to pound the middle out of a pound coin, use explosives!

As a matter of fact, he does have a loicense to blast the queen in the face But not so hard that he makes a new hole

Comment from : @suggesttwo

Excellent demonstration and narration Anything to get the kids (and adults) hooked on Chemistry can't be a bad thing We need more scientists
Comment from : @bertrandruskin3406

Use more coins boss it’s your right
Comment from : @fourkings1k855

Please thumbs up my last comment me and my family could use the help
Comment from : @johnmack6523

How can you say you did not mean to pop the center coin out It dose not take a chemist to know what would have happened with the washer under it
Comment from : @fuldk

Many years ago I worked in manufacturing with a former US Navy SEAL who had significant Vietnam experience He was always on edge, yet never had any threats to worry about It really messed with his psyche So, one day I noticed a help wanted ad for a company that did "explosive fabrication" making sheet steel plate into tank parts and such brThe process they employed was similar to this video They would clear an area with a bulldozer, set a negative metal form on the flat, place very thick steel (or whatever metal) plate over it, cover with explosives, mound earth over it, and ignite Produced the same result on a huge scale It was perfect for formed metal parts that could not have weldsbrHe applied for, got the job, loved it, and lived happily ever after as far as I know

White phosphorus dissolved in carbon disulfide, dripped onto potassium chlorate ?
Comment from : @kieranodea771

is it not illegal to vandalize currency here in the UK
Comment from : @dl4350

The reaction of the much less reactive red phosphorus is also violent and dangerous This mixture is called Armstrong powder
Comment from : @donbarnett2890

I've had dreams of putting my warm rod, onto the queens face
Comment from : @hokiepokie333

So when they weld sheets of metal together for construction projects do they use a much more powerful explosive? I know they use a greater quantity Why does it weld in the latter, but with the coin, the metal plate only deforms without any welding taking place
Comment from : @slowburntm3584

What's interesting is that US dimes, quarters and half dollars are made from three layers (a center core of pure copper, with the outer layers being 25 nickel, 75 copper) Before the blanks are cut out, the sheets are "explosively bonded" togetherbrbrSo that should be the next test-see if you can bond three layers with the same technique used here
Comment from : @almostfm

Red Phosphorus and Potassium Chlorate is just as dangerous A friend of mine (now deceased) lost an eye when, in his teens, he mixed the two in a plastic spoon
Comment from : @richardamullens

Completely demistified the magic wand
Comment from : @agerven

you're allowed to deface currency for the purposes of scientific demonstration, it's a lawful excuse for a charge of currency defacement
Comment from : @domvasta

sir I have a doubt that does it release any heat or fire
Comment from : @hymabhaegavi1255

"High voltage coin shrinking" is more interesting
Comment from : @peglegnoid6139

Nitrogen triiodide (spelled right?) might do the same thing also I could not tell you though That is just because I would not trifle with such a chemical
Comment from : @JohnDoe-gm5qr

oy mate, u's got yor coin destruction loycense

I would hesitate before letting a man named "Gamble" handle explosives in my proximity

The metal impression look like the time when the royal mint struck the pattern coin on a lead plate It is very intersting !
Comment from : @vacciniumaugustifolium1420

ya going to jail mate for damaging 2 pound coins instead of one pound coins lol
Comment from : @jinnerbom

Thanks for the warning, you certainly do have loud bangs
Comment from : @ericyoung8741

how about blasting the middle piece back into the coin?
Comment from : @waldsteiger

Wow, neat! :)
Comment from : @deplorableamerican9451

I'm afraid that they are the queen's pound coins, not yours
Comment from : @jacobmortimore

Let's try to blow the coin back into the ring
Comment from : @FlyingSurprise

"Got change for a pound mate?"brbr"Yeah, block your ears"
Comment from : @NomadUniverse

You could do this video for half the price now
Comment from : @thepoopenator7341

You can easly separate the two parts of the coin by pressing a bit on it's sides, with a vice It doesn't really require much force
Comment from : @arandumendez9557

Under Section 10 of the 1971 Coinage Act - No person shall, except under the authority of a licence granted by the Treasury, melt down or break up any metal coin which is for the time being current in the United Kingdom or which, having been current, has at any time after 16th May 1969 ceased to be sobrbut it is a cool experiment
Comment from : @jimsbooksreadingandstuff

Why you're not allowed to damage coins, is your money

Wouldn't the new pound be okay without the washer ring?

That new £ looks like our Canadian toonie
Comment from : @ratpoutine

Why is the UK strict about coins?
Comment from : @WLOfails

In the states, it is also illegal to destroy currency, unless done for the sake of education Is this not so in the UK?
Comment from : @detritus10001

Destroying currency is illegal
Comment from : @jakepollen6839

And now for the £64,000 QuestionbrbrWhite phosphorus is pyrophoric, which means it spontaneously combusts when it comes in contact with air How were they able to do this experiment?
Comment from : @jmowreader9555

You most certainly CAN remove the center of a pound coin with a hammer and punch Very easily in fact Putting it back is another matter
Comment from : @rickharriss

yes sure you havn't spent any university money because you used a 1 pound coin from your pocketbrbut i guess you also paid everybody from your own pocket, and bought the metal plates and the explosives from your own pockets
Comment from : @FalcoGer

He’s brilliant Why didn’t he teach me Chemistry at High school, I may have pursued it
Comment from : @AC-SlaUkr

i thought he was talking about st Annes for a moment
Comment from : @michaelsnow7252

Well The coin was not damaged! it was disassembled :D
Comment from : @RPBCACUEAIIBH

Why do you use white phosphorus and chlorate instead of something "save" like hmtd or leadstyphnate or leadazide?
Comment from : @annaneal2970

0:33 I've always wanted to see this clip of Col Shaw You can really see how far that iron rod bent - almost double - as it smacked him on the head

RIP Headphone users
Comment from : @Mytubecleaner

You should use currency from outside GB That way any governing authority will be outside the jurisdiction For example the Secret Service can't get at you in England if you damage US coinsbr The US Secret Service is the "money police" in the US If you are counterfeiting in the US, it's not the FBI that comes after you, it's the Secret Service
Comment from : @erictaylor5462

Jim Gamble? He's a licensed explosives handler? AWESOME surname!!!!
Comment from : @discosteve8666

An extreme example of devaluing capital
Comment from : @charleygrossman8368

you are also not allowed to counterfeit coins in aluminium
Comment from : @geofflotton5292

"We haven't spent any university money on trying these demonstrations" What a thing to worry about!
Comment from : @NathanGreenberg

In America there is a law stating that US currency can be destroyed for educational purposes
Comment from : @zacharylee3296

Have you tried analysing the structure of the coin afterwards?
Comment from : @Cleric775

How much energy released per gram?brThis is definitely greater than 1 kilo-Joule, if not at least a Mega-JoulebrbrHowever, this could be tiny in comparison to Kim Jong-un's Hydrogen bomb
Comment from : @Cleric775

For what it's worth, I think it's a myth that it's illegal to damage coins - Edinburgh Zoo has a machine for pressing coins flat, with a whole screed about the history of this belief next to it!
Comment from : @0olong

Why did the old experiment use an American nickel?
Comment from : @kermitthefrogjc

Just use a Euro Coin, you guys aren't using them, so it'll probably be ok to do over there!brBesides, no one has a monopoly over the euro coins, so I highly doubt anyone will persecute you

The £1 coin is like the Toonies we have here, except it's the reverse Nickel on the outside and aluminum bronze on the inside
