"The village that gave its name to the element Strontium." What an excellent and exciting motto.

[@Georgiancorner]

4:37 one of the warmest & cutest smile ever!

[@seffard]

You are wrong professor, your radioactivity explains your hair lol

[@dionslayer1]

Stront in dutch means shit so every time in chemistry when we are talking about strontium the hole class bursts in to laughter

[@HeisenTwerk]

you guys must be so mature.

[@Curlytop1955]

Don't worry about your hair Prof, mine is just the same - thick and bushy, as already apparent in the pic of myself as a toddler.

[@txdmsk]

Ah, I love periodic videos. I throw my arms up whenever I find one in my subscription box.

[@theangledsaxon6765]

The rainbow that leads to the pot of gold... Err I guess the pot of strontium

[@countyfacts6920]

One of your best videos. Thanks to all who worked on it. My #1 right now has to be palladium. Amazing.

[@jimsvideos7201]

If the narrator in the a-bomb film sounds like the Academy gardener from Star Trek, you're onto something.

[@punishedexistence]

Wow, I can say I learned something today...these videos should really be more famous; maybe they already are, because not everyone spends hours out of their day watching these. I however do not represent everyone! Thanks for the upload, very interesting!

[@pyr0ph1L]

I love strontium nitrate. Gives a great red colour in fireworks :)

[@djehuty13]

You get strontium over the world, but THIS is Strontian's strontium! :)

[@CorruptedEditz]

You know your in Scotland when it's raining

[@foely1]

pete freakin' loves reations

[@PBrown471]

I'm not much of a biochemist, but when asking the question about the interchangability of elements in a biological process one must consider that although Ca and Mg are in the same period they're quite different. For example, Mg atoms have a radius of ~1.7Angstrom whereas Ca is bigger, ~2.3 Angstrom. Also, they exhibit different crystal structures too, and this i think would be an important factor too. I don't disagree that there isn't Mg in bone, but i would say in PPM concentrations

[@davidrv17]

I seriously love Pete and his passion... but I guess anyone would be that passionate when you get to ignite stuff like that all the time

[@ShenlongArcane]

This should be made a public broadcast tv show.

[@CYFilmStudent]

Love your videos, looks like a nice trip.

[@williamkendrick]

as a computer designer, i have always wanted to be a chemist, and your videos never fail to amaze me. just please please please back up all your videos, you never know when someone might try to hack your password... i've seen it happen all over youtube.. and to have that happen to you guys would be a catastrophe!

[@clearmenser]

Big Periodic Videos fan here (and all of Brady's other video works). And after watching the strontium video I can say that I would have been fine without the preview. I think that since youtube is such an archival medium that unlike television or radio we don't really need teasers for what's coming up next. If we like a channel then we're subscribed and it will come up when it comes up. There's even no need for sorry-for-the-lack-of-recent-updates apologies. Just keep doin what you're doin :)

[@storyspren]

All the years of science have molded his hair into the physical picture of science.

[@joohop]

brilliant vid lads and ladys

[@BigBrothersEnd]

The height of the mountain allows to see from a spectacular angle the rainbow at 0:46

[@koosh138]

didn't they also find strontium in Gladiator's bones?

[@gonzogriff]

Oh scientists, you so silly :). I have always loved the elements but I am doing horribly in honors Chemistry with a C. I still find these very entertaining and informative!

[@SciPhi161]

Hahah. The old Scotsman was awesome.

[@tchunu]

Great video, thanks for uploading.

[@sion8]

How is 'Gallium' more straight forward than Francium?! Gaul was a Roman province which included today's Belgium and Netherlands and pieces of that today belong to other nearby places. While France which comes from the Franks, is just more common in today's world.

[@RealRaynedance]

I want to go to Scotland now.

[@Barnekkid]

Good video, I really enjoyed watching that.

[@daedra40]

George fox, would love to see a more insightful interview of him :)

[@zechariahnimon4230]

More Chemistry Definition videos, more discussion of elements videos (perhaps pertaining to their different properties), and more discussion to accompany the new the slow motion reactions by the professors. Please

[@scott6525]

Another great video

[@OOZ662]

I've been waiting for this one, being an EVE Online player.

[@OOZ662]

@hitachi088 In this case, because you use an item called "strontium clathrates" to allow your starbase to enter "reinforced" mode when attacked so that you have time to muster a defence.

[@Ben79k]

I know you guys are in the UK there, but i like paniced when i saw both cars at the beginning driving on the left.. haha awesome videos still, keep it up!! :D

[@dradeel]

I think you could have shown more clips of George Fox. Seems a little wasteful to make the trip, have him take time of his day to talk with you and show you the mine, and only have him speak for one minute in total of the almost 7 minute long video. I would've liked to hear him tell more about the history of the mine and discovery etc. Seems like a lot could be said about what you summed up in one brief sentence at the end of the video. Other than that though the video is great as always! :)

[@ACoroa]

Is this element reactive with water?

[@skilllol101]

gotta love those flames :)

[@oBCHANo]

@ScotsmanRS No, actually i didn't. That doesn't change the fact that the guy collects lumps of metal.

[@somorastik]

Hi, I love your videos, for experiments where you film explosions and burning, you should use a filter for the camera to lover the exposion. Especialy for slow motion videos. Keep on rockin!

[@MrLol333]

Only 1 word: amazing ...

[@TheCptSam]

Old fart, maybe. Boring defiantly not! History is an amazing thing. :)

[@knightnicholasd]

Wow, the old man definitely got himself a haircut. Lookin good Professor!

[@sazerchu]

From my understanding yes and it actually bonds with carbonate from the Carbonic Acid Buffer within the bone matrix. All of the group 1 and 2's humans use do so. Its an on-demand thing like many of the other elements we consume. The bones act as a repository for the numerous 'buffers' that keep us alive.

[@hainleysimpson1507]

Strontium. No wonder old people smell funny.

[@Kaiju3301]

Its so beautiful over there.

[@FrozenHaxor]

Gotta try Strontium Nitrate flame now :S

[@sakokosa]

As far as i know they still date the animal remains or seeds at major archeological sites to date the site accordingly or sometimes they use pottery and tools excavated from the sites to match the time period. thanks

[@sakokosa]

@periodicvideos Love your videos and appreciate your work. Bit off the topic, would please make a video about carbon dating and archeological dating system used now a days. I saw a video from prof. a long time back talking about why carbon dating cant be used now a days due to changes in C14 in the atmosphere after invention and use of nukes (I guess i am right). But I always wonder what technique they are using now, to date all the historical sites and other things .

[@ScotsmanRS]

@oBLACKIECHANoo He is introduced as the village archivist, not the Strontium archivist. In other words, he'd collect information about the village in general, and strontium is only a part of that. Besides, the things he had weren't lumps of metal, they were lumps of strontianite. Is there anything else you'd like to be wrong about or are you finished?

[@PianoKwanMan]

Brady, you are becoming more and more like a chemist like at the end of the video you seem to know your stuff :)

[@MountainFisher]

Besides being radioactive fallout just what does strontium do?

[@theangledsaxon6765]

Mhhhh baby, strontium is in the air tonight, oh lord

[@RealRaynedance]

Might I ask HOW you kept your composure when he said "People like me are radioactive. Doesn't explain my hair..." ?

[@tomledge1]

Lawls - this was on my chemistry paper!

[@marxmith]

Has anybody else figured out how relevant this is to the series finale of Breaking Bad? The answer is VERY.

[@sazerchu]

There are trace amounts of Sr as well in the bones. Mg is more used in internal cellular processes involving electron transfer and molecule synthesis.

[@Somethingyoumayknow]

Very Cool.

[@ScotsmanRS]

@oBLACKIECHANoo No, it's not the same thing. Strontium is an element; Strontian is a village. His speciality is the village, not the element. Did you pay any attention to the video at all?

[@PifWorks]

I always loved that Element, cause in Italian it sounds pretty similar to the word people uses commonly to say "Feces".

[@commodork]

I would not be surprised if that reaction generated massive amounts of Infrared emissions.

[@Gunglove]

Was the name of the mines perhaps Moria?

[@ThatNateGuy]

Agreed.

[@killermonster555]

Strontium is used in red fireworks. It is also given quite a lot of stick in the netherlands and belgium as "stront" is dutch for a certain word that starts with sh- and rhymes with wit. XD

[@oBCHANo]

@ScotsmanRS Same thing, the guy spends his life collecting lumps of metal, to make it worse, lumps of the same metal.

[@sakokosa]

@passwordresetisbroke ya you are correct, but I was asking about the technique used now a days. I have heard many a times that you can not use carbon dating anymore because of all the atomic tests, the balance of C14 in atmosphere is changed. In short if you have some amount of C14 in a piece of a cloth, which is suppose 1500 years old, that amount wont be correct as after 1940s that cloth may have acquired more C14 in it due to nuclear use in open air.

[@rtpoe]

@Erikur17 So, Strontium was discovered by digging in someone's nose?

[@adracamas]

What exactly would happen if iron dust from space were to enter the atmosphere? Would it burn?

[@EnzoLapras]

A haircut? Impossible!!!!

[@ScotsmanRS]

@oBLACKIECHANoo Most, if not all, of what was on that shelf was lumps of minerals, presumably strontianite. That is not a metal. That is one of several things you are wrong about.

[@DeoMachina]

Woo Scotland!

[@MidasMeridian]

Go 720p!!! :D

[@sakokosa]

@metfan89 thanks mate.

[@ScotsmanRS]

@oBLACKIECHANoo That is not what it says. He is a Strontian archivist not a strontium archivist.

[@bereal666]

at the end of this rainbow, there would be a pot of strontium, and a very very green greenhaired Professor

[@metfan89]

@sakokosa still use C14 dating, just cant use it to date anything post nuclear age reliably, if you want to learn more visit potholer54's channel. he has a few good videos on it.

[@AntiProtonBoy]

cobalt-60 next plz

[@tomattosfutleimierda]

@MarkusNemesis i know :C

[@kiddolols]

ohh different hair style! Professor!

[@thatoneguy12ize]

Did he say rainboa?

[@StevenRamosx13]

so what happens if you lick the rock?

[@strikermovies4u]

No idea...

[@guntertv304]

i d´now why they use it under the fume hood . potassium is more dangerous and they put it on the table. ://

[@alexmcmahon2810]

Strontium rainbow!

[@wyvernlord23]

What does he mean he's never seen strontium. He saw the entire periodic table (save the radioactive man made ones) when that guy who builds periodic tables came.

[@fugehdehyou]

I love how everyone who wears a labcoat vandalises it by drawing or writing things on it. I am one of those people haha

[@emmaabdullah9046]

Nice

[@tomattosfutleimierda]

i love heeeeeeeeeer *-*!

[@CRAIGMASTER2]

Similar to the color of a red flare

[@hanish1997]

sickkk

[@XOIIOXOIIO]

LOL "It doesn't explain my hair:

[@chrissydude1]

The professor LOOKS like science.

[@dylanlawless1]

I wonder will Mr Fox appear on Backstage science. I'm sure he had other interesting things to say.

[@Erikur17]

Strontium is also the only element with a Gaelic name. The village name Sron an T-Sithein means "Nose (ie as a geographical feature = Peak) of the Fairies (Sithein = people of the Sidh, the burial mounds, the same Sidh in Ban Sidh (or Banshee); thus strontium like nickel and cobalt is named for a supernatural being.

[@luigi14444]

double rainbow all the way 0:46

[@shamarone]

2:51, seems like rocket candy.

[@toratorasama]

I see the professor has gotten a haircut. :3

[@martinzhang5676]

A bit like how English speakers might react when they hear someone say the planet Uranus.

[@DevilMaster]

No, it does. (mathematician's answer :-D ) Maybe the "combustion mixture" (is this Periodic Videos' response to the Mythbusters "mixing blur with blur"?) contained potassium permanganate, which led to the red and purple flame, instead of the red and yellow flame that would be expected from strontium.
