Bunsen Burner - Periodic Table of Videos

[lekoman]

One wonders if Professor Poliakoff realizes how funny he is? He's either unaware, or possessed of one hell of an impressive deadpan.

[SeriousBusiness100]

I love the cool trick of getting a match to sit inside the inner blue flame of a bunsen burner and not get set alight.

[PainSurgeon]

In one of the ventilation chambers at our college, mostly used for the Kjeldahl method, there's a bunserburner-tube that's heavily corroded by spills of sulfuric acid. I saw that it's still used by students however. Time to be worried?

[MrSuednym]

I had to tell people how to work a bunsen burner in Microbiology lab today... Most of the people in there are premed... I'm scared.

[aluisious]

Wouldn't the thing to have done when the hose was burning is reach over and turn off the gas? Before you even go for an extinguisher...

[Sarov452]

Lol

[IqsMontegro]

them 3 dislikes are from the "Really Stupid" student lol!

[osmadn]

this gets screwed XD 0:48

[Typho0n86]

Smoking isnt aloud in the lab any more :(

[LuxuryBarrage]

The stupid student disliked this video three times.

[SabretoothSnowMan]

Just images what that would look like. That student needed to have his head tested.

[lexichronicle2]

I've got one up on Martyn, I saw people at my school lighting the gas taps themselves :D

[Crimsanity]

My classmates are stupid enough to keep the gas on while looking for a lighter....

"he can't smoke in the lab anymore"! Nice!

[Zenoniel]

The professor has a tie of the periodic table! Cool xD

[TheGalacticCannibal]

'At that point, I realized... I didn't know where the fire extinguisher was.'

I quite literally woke up my dog laughing at that.

[flyaxe]

there's nothing more beutiful then a flame. or atleast not much :D

[1ukjunglednbraver]

turning off the gas tap would be best

[BlackSkullRacer613]

Great video, but you should have mentioned other forms of Bunsen burners such as the Meker-Fisher burner. I use that in the lab more than a regular Bunsen burner.

[lhtd]

You should have spoke a bit more about the uses of the Bunsen Burner in Biology and Medicine.

[migkillertwo]

Science bitches!

[Simes158]

I never realised it was the unburnt carbon that gave the 'yellow/orange' flame its colour, but it makes perfect sense now. That's something to explain to my pupilswhen I teach about air quality / pollution and soot.

Thank you.

[Evertonian94]

Yeah make a video on a titration :)

[aceofspade1800]

Can you do a video on titration please?

[jaflkbngfpnt]

I remember that back in school we used to open that air valve very quickly on a lit bunsen burner causing a short but quite high flameball erupting. fun times =)

[DevilMaster]

And I thought an ex classmate of mine was stupid for using a Bunsen burner to burn a pencil during class.

[ganaschico]

i wonder if that stupid student is watching this video

[multaflor]

ALWAYs light the match first professor before turning on the gas.....

[JessicaHellsten]

I miss using the bunsen burner in highschool! I haven't used one in my first year so far at uoft... we've been using hot plates instead.

[silentelysium]

@JessicaHellsten Me too!

[M1XR]

@JessicaHellsten i Think the idea with undergrad labs is it removes the risk of fire .... thats what it is for me in UCD ireland anyway

[JessicaHellsten]

@M1XR It`s the same reason here. I was just saying I miss using the bunsen burner. It`s just a little more exciting to use.

[TheBurningSeraphim]

"and im sorry to say it, he was stupid"

[Zdawg2324]

@TheBurningSeraphim i'd hate to be that student and watch this.

[downfader2]

I remember a lad setting his back on fire in a college lab. Instead of asking "excuse me may I pass?" He leaned back over a burner and his coat went up in flames, proper stuntman style. Completely unscathed thankfully!

[09876124]

Thw smoking joke was sick. :-D



[Almontmarine]

dun leave the gas on too long. light the burner quickly! btw my school uses a gizmo which u press and a spark comes out... (the gas is poisonous...)

[Almontmarine]

the glass stretching part was so awesome and shocking!!! sorry but i'm only 13 yrs old that's why...

[jq747]

At school we used to light the gas straight out of the gas tap... made a nice flame thrower, especially in the old days when they used LPG rather than natural gas, coz it was under much higher pressure. We never blew the place up, god knows why.

[StringsCrusader]

i love these videos.

[bumpercarBOOST]

I LOVE HIS HAIR

[rabbitsib]

How many of you ever been in Chem Lab and had a student set the waste basket on fire after lighting a bunsen burner?

[aopdjasldksa]

Someone left the inline tubing on the flame...

How stupid do you have to be to not notice that?!

[Ormaaj]

Dang got enough fume hoods? There's like a row of 10 of em there.

[AwFiles]

No Tina Turner ?

[RathaWynter]

"... and anyway, smoking isn't allowed in the lab anymore." - The Professor has a great sense of humor at times.

I was hoping that a video on the Bunsen Burner would come out, and here it is. Had no idea it would be quite so much fun either. Its always entertaining listening to what the folks at periodicvideos have to say, especially the stories that The Professor has to tell. Thanks for everything you guys (and gals!) do for us here on Youtube, and for sharing your experience with us.

[freddiejos]

smoking isn't allowed in a lab anyway... LOL

[killernat]

wouldn't it be a pipe rather than a tube because its not flexible

[WhiteRAZOR]

Does the size of the air holes matter? I remember in school our holes were tiny compared to this one.

[3doog]

My favorite thing in chemistry class!

[mance1234]

Why is the Proffessors hands shakeing :S

[punishedexistence]

I remember a professor in my chem class talking about smoking in the lab...technically, you could just stand by the fume hood and the smoke would go away, and he said it wasn't even due to flammable material. The reason was because you never never NEVER put your hands anywhere near your mouth while in the lab. Especially when working with any hexavalent Chromium compounds. The same went with food, drinks or gum.

[ThatGuyFromAustria]

Another important thing is to put the lighter/match above the outlet *before* turning on the gas. A school buddy of mine lost his eye brows because he got that wrong…

[imalwayswatchingu00]

Chemistry test for me on Monday..

Yay?

Swear i learn more from these videos though.

[clodester]

an amazing vid yet again Professor. I love them all. I especially like the slow mo action. Maybe there are more chemical reactions that would benefit from Slow mo footage, could be a new mini series?

As a side note, a guy in my Secondary School chem class managed (Prob on purpose) light the gas tap directly and caused a similar flame thrower direct from the gas supply. The teacher panicked but just turned the tap off at the bench and the flame extinguished straight away.

[vitaminD11]

i wonder why the profs.hands shake so much? does anyone know.

[TheOverkill102]

You guys are awesome :P

[jeebersjumpincryst]

Thanks Prof P and Brady. I could just listen to the Professor talk ALL day, easy peasy.

[gulllars]

Request for a video on rotor evaporator.

[kracka7]

Mr kindshi?

[grndmstrjoe]

Bunsen Burners >>>>> sand baths, without hesitation; however, 3 people like sand baths more than bunsen burners



[dogbishop]

3 people inadvertently burned through the rubber tubing to their bunsen burners.

[DevilMaster]

@dogbishop Or that student was butthurt to hear the professor's opinion of him, so he retaliated in the only way he could think of: by making 2 fake accounts and disliking the video 3 times.

[WillyM79]

Bunsen Honeydew LOL

[NinjaMotion]

i love stuff that have a slut on the bottom too! :D

[jkazos]

Dear lord, watching you with your hands so close to that flame, with the glass seemingly on fire before you...

I about lost it, there. Nerves of steel, you have.

[doverlin]

What a coincidence. I bent about ten glass tubes to varying degrees to make straws for a friend who is dying of cancer. He is sensitive to the taste of plastic. I thank my chemistry teacher of over 35 years ago teaching me how to manipulate glass. Mr. Kneeland . . . I should have taken up his offer, but that's another story.

[Wolfendale69]

LMAO i love how he jumped to the topic of smoking cigarettes from burning flesh at the end

[sirkowski]

The anecdote made me laugh.

[Mees401]

We use the same shape of bunsenburners in our lab, but I prefer the ones with a flat nozzle on the bottom of the metal pipe that you can screw looser or tighter.

[1RadicalOne]

No need to apologize for calling the student stupid. They exist, I assure you:

"So if the energy is greater than 6.4 eV, the electron will escape"

"What if it was less?"

"Then it will not."

"...So...uhhh...what if it was, like, three, or something, you know?"

"*squint*"

[sonicase]

...if you burn a hole in the tube and fire starts coming out like a flame thrower,... you just turn off the gas

[JimPrower]

@sonicase Okay. You try it. Try to reach a knob with a flaming tube flailing about between you and it.

Doubt you can. I am glad labs have a central emergency shutoff, though, and, Prof. Poliakoff (sp? apologies if it's incorrect,) I'm glad it wasn't worse than a desk catching fire.

[sonicase]

@JimPrower you could do it, you just move the tube and do it, the flame that comes out isn't too big.

in my second year of chem this kid knocked over his bunsen burner and started coming out exactly like that, he didn't know what to do and started to panic, i just reached over and turned his gas off, problem solved.

it also helps to have fireresistant lab benches which the prof may not have had

[JimPrower]

@sonicase It sounds from the Professor's description that much more gas was coming out of his student's tap than your friend's. If it set the bench on fire within a minute, then I would guess that the tap was wide open.

[sonicase]

@JimPrower lol right dude you know exactly how it was don't u

[emendamcg]

WHO...THE HELL...DISLIKED THIS VID!!!!!!!!!!!!!

[sirkowski]

@emendamcg The stupid student maybe? lol

[FiliPinoy95]

sodium is in glass?

[puncheex]

@FiliPinoy95: Not necessarily, but sodium is in your perspiration, your fingerprints, and even in the air; it's not surprising it might also be a impurity in common glass. It produces a brilliantly yellow flame, and very often wipes out the more beautiful effects of copper and strontium in flame tests.

[mistulac]

wow nice

[cristoretornebiblia]

The one person that disliked this is that stupid student that burnt the desk with the Bunsen

[Holyshadoww]

YESS first to dislike

[wednos]

@Holyshadoww

gtfo

[JoiDior]

I absolutely love this channel!

[TheIronTank]

Bunsen Burner: The only time when my lab prof should keep an eye on me. I burn way too many unnecessary things. I don't know about you, but I just like burning things to see what happens. Oh, and playing with the flint to get little fireworks by splashing it onto the fire is fun too :D

[puretroubleman]

so smoking was allowed in the lab at one time?

[periodicvideos]

@puretroubleman check out our more recent video on Rutherfordium at about the the 1:45 mark!!!

[puretroubleman]

@periodicvideos lol what a memory you have :) that was from 2 years ago.

[periodicvideos]

@puretroubleman stuff like Earnest Rutherford smoking in a lab I remember... The day I'm supposed to put out the recycling bin has me flummoxed every week!

[mrhulot101]

@periodicvideos Peter Desaga was Bunsens lab assistant

[tybo09]

@periodicvideos One of my professors had 8mm film from a lab session from his University days... The professor stopped, mid-experiment, to light a cigarette from the burner that was underneath the liquid he was heating.

The Health and Safety folks would have a field day with that now.

[TadRaunch]

@periodicvideos You and me both, pal!

[TheScientist0000000]

@periodicvideos Do you guys think you could do a video about cavitation?

[bfesser]

@puretroubleman Apparently Linstead (phthalocyanines) smoked a pipe while working in the lab.

[Downfacingdog]

@puretroubleman Smoking was allowed everywhere at one time, until the inter National Socialists or InterNazis came to power.

[personperson666]

You're not supposed to stick the glass straight into the flame you're supposed to wave it in and out of the flame the preheat it so it doesn't pop or explode. But it's fine it didn't, so it doesn't matter.

[hanzithaking]

my cem teace always says we soul newe use a licte on a bunsenbune

[Brandonduboff]

your first text book was on organic chemistry? Impressive, i thought everyone started with elementary mathematics.

[Brandonduboff]

CAREFUL SCIENTIST, ITS HOT!! =)

[chthonicfire]

I remember back in my old chemistry lessons and we were making glass "balloon animals" out of glass tubes using a bunsen burner to heat it up

[BaKer312213]

undergrad labs, standard

[TomMarAlem1987]

AND YOU KNOW WHAT WE CAN CALL THE FIRST SUCCESSFUL IGNITION THROUGH A BUNSEN BURNER?

AN OLD FLAME!

[BuickDoc]

Don't forget the Bunsen Valve. It is created by a slit in rubber tubing so that, if one end of the tubing is sealed, gas in the tubing can escape from the tubing, but gas or liquid trying to reverse the flow will cause the sides of the slit to close the slit, thus preventing back flow. In other words, it is a one-way valve.

[BYMYSYD]

I saw this on google, and he first thing i thought was that the periodic table of videos was going to make a video about this.

[periodicvideos]

@BYMYSYD The Google logo is what reminded us to do it!

[rjhrjh3]

@periodicvideos That was fast getting this out in one day! Good video.

[Kestko]

my teacher says never to use a lighter to light a bunsen burner, because the lighter might blow up in your hand...

[joetheking78]

@Kestko Your a student he's a professor i hardly doubt he would give it chance to blow up.

[kapwul5]

@Kestko Why would that happen?

[imakingprawnok]

dont forget Dr.Bunsen and beaker!!

[ncheung888]

excellent video!

[FHomeBrew]

My chemistry teacher once put the flame to "near invisible" (very hot) in stead of turning it off. When he went on teaching, swinging his arms through the flame unknowingly, he almost caught fire. The entire classroom was silent except for the gasps and sighs every time he almost caught fire.

[sk8shred]

0:15 =O I'm not allowed to light the burner up that way on school xD, well i do it anyways ;P

[feuermann88]

i use bunsen burners models where you can control the gas too =)

and I'm a very very stupi chemist student ^^ (thousand of things brokens)

[pietermarten13]

epic

[nishbrown]

Methane, youthane, we all thane!

lol

Excellent vid, as usual!

[huntingvuk]

another great video thanks, not a single instructor had even mentioned Bunsen in a lecture I heard too bad,more interesting than people would think, THANK YOU!

[aSongScout]

The glass goes all soggy. lol

[lampyman101]

I just have this image of a birthday cake with 200 Bunsen burners instead of candles and it being to hot for anyone to get near enough to blow them out

[SocCapAth]

I'd say having developed something that is now in every high school science/chemistry lab in the developed world is not too shabby.

[nronaghan]

Once in organic chemistry I got a tube for my bunsen burner that was very old and worn and didn't really fit the burner. I tried it out (stupidly) anyhow and when I lit the gas the entire burner, and some of my bench, caught on fire. I just turned off the gas and it went out, no extinguisher needed!

[wenzelsopinion]

"…smoking isn't allowed in the lab anymore!" LOL!

[fstroch999]

haha, good joke at the end !! hihi

[mV33rs]

I loved this episode :)

[TheBoyFromNorfolk]

I've always found the very hottest point of a bunsen flame is about 1/4" above the point of the inner blue flame, rather than it's actual tip.

Have you seen the demonstration of the different levels of heat in a bunsen burner with a match? there are parts where you can keep the head of a match unlit.

I don't have room for my own gas tap disaster story, but the gas shut off point is much more important than the fire extinguisher. Cut off the gas, and the flame goes out right away.

[odysseus9672]

One of the cool parts is that as the glass heats up you can see the flames coming off it switch from orangish-red to yellow. This is just what you'd expect from the bright yellow lines in the sodium spectrum.

[Jigiligy]

That student was probably RWJ

[WaynetBago]

It's on google main search page too !! :)

Really nice video !

[pyroguy1030]

NICEEEEEEEEEEEEEEEEEEEEEEEEEEE­EEEEEEEEEEEEE

[thewiseowl]

Stirrer hotplate >> Bunsen burner.

[culwin]

Nice trick.... claim you don't know something, so that the students will go look it up and learn something! Tricky! :)

[QuarkyGideon]

I can wave my hand through it and throw paper planes through them too! Don't do it with the blue flame though... get someone else to do it... ;-)

[ilvmusiclol]

@QuarkyGideon reminds me of a physics experiment we did on speed, some people in the class had the same idea as you, seeing how fast it had to be going not to catch light!! :) happy days

[brt5470]

Actually really cool. Great video.

[oBLACKIECHANoo]

this is classed as a invention?

[flakemusic86]

The lab assistant's name was Peter Desaga.

The original invention was made by Michael Faraday, Bunsen and his assistant optimized it later on.

[heilla88]

@flakemusic86 Seriously... who cares? xD

[sinprelic]

@heilla88 who DOESN'T care?

[tyeedillon]

Happy birthday Sir Bunsen!

[halla369]

you did it wrong! :O  first light the match and then turn on the gas!

[heilla88]

@halla369 Seriously... who cares? xD

[halla369]

@heilla88 it you first turn on the gas and then cant light it before some seconds later it can go boom and your hair go's bye bye

[Muscleduck]

A small Wikipedia quote: "While his building was still under construction late in 1854, Bunsen suggested certain design principles to the university’s mechanic, Peter Desaga, and asked him to construct a prototype. (Similar principles had been used in an earlier burner design by Michael Faraday as well as in a device patented in 1856 by the gas engineer R W Elsner.)"

This is probably the most used tool in any lab, apart from beakers and such.

[poelfkat]

happy Bday

thanks for making heating things a bit easier

[Cube3Productions]

i only noticed coz google reminded me what today was

[xKevTiffx]

Glad to see the little things that we take for granted in science.

[misterwobblehead]

sweet....Happy 200th Bday Rob Bunson.....without him, it'd be a lil harder to make meth...i mean chemicals and shit

[101techkid]

Nice

[thetitanjon]

Happy birthday robert!

[Ayjayo]

Not gonna say it...

[MrValzen]

@Ayjayo

Say what?

[Supacalaz]

@MrValzen Big hot buns

[jeebersjumpincryst]

@Ayjayo Awesome, man!(/woman)

Well said.

I had to go all the way back to check, and sure enough, my suspicions were confirmed!

Thats one of my all time, pet youtube hates. Thumbs up for you, though!!! ;)
