Favourite Reactions - Viewer Questions

[ChemistDrummer]

Professor Stockmann, you spoke about calicheamicin γΙ. Fifty points to Stockmann-dor (in a Dumbledor voice)!

[TheLightningStalker]

Copper + Nitric acid

[elflordbob1]

...chemistry junkies

lol

[LV07TSK]

Barking Dog Rxn is found in the SULFUR video.

[LV07TSK]

Favorite Rxns: #1.TRAFFIC LIGHTS  #2.THERMITE

[AvnitRag]

my favorite reaction is reaction of sodium,potassium, rubidium. Caesium with water.that is reactive metal (alkali metal) with water. the different color of flames and the explosion they make excite me .. :D

[samanbandana]

organic chemists are boring! 

[oomblikkies]

What about the iodine clock reaction - also quite pretty.

[Deeredman4]

is there a place we can see the full videos?...I'm kind of curious too see what that guy was talking about that they "found in a rock"

[av733]

At 3:37 that guy looks like darling from blackadder

[Breyyne]

I would love to see a video of the spherical salt reaction he talked about in this video.

[626129ify]

why do they not have more veiw's. this is a amazing channel to watch if i was you i would post this on face book to bring up the view's

[saschamuecke]

7:04 looks and sounds like a light sabre! ^^ Very fascinating!

[leokimvideo]

we all love bucket chemistry

[ILiveForScience]

This is definitely my favourite YouTube channel, thank you Brady for this brilliant video : )

[rolandas1985]

My favorite reaction is Hydrogen with lithium nuclear reaction :D

[soberek]

We want to see Steve Liddle's reaction on periodic videos !!!

[dang3rousgoldfish]

My favorite reaction is when you but aluminum metal in a solution of both copper sulfate and sodium chloride because the copper should precipitate out of solution without the sodium chloride but it doesn't.

[Pavle245]

Will there be a video with some superacid, for example fluoroantimonic?

[94carbonteg]

I enjoyed this vid; I love being a nerd lol :)

[curlyhairhead]

My favourite Reaction is by far the Briggs-Rauscher reaction. It is just stunning to see an oscillating Reactions, especially because it's just against your "natrual feeling" for reations.

[UnreliableMaster]

It makes me cringe when people pronouce Wittig wrong xD

[innocuoushunter]

my fav reaction.. H2 + 02 ---> 2H20 ... LOL!

[TheRightNeutrino]

@innocuoushunter u got it wrong

[AssemblerGuy]

Heh, the guy at 3:12 talks about molecules as if they were brilliant chess moves or something... :-D

[tybo09]

I must admit, I'm jealous of you all. You have passions for your job and truly enjoy what you do. It's great that the spark hasn't been extinguished by a callous superior or colleague.

I love that you share the spark with so many people, too.

Keep it up.

[tybo09]

[punishedexistence]

I love it when people speak my language, especially very attractive women! :) My personal favorite reaction is that between ethanol and my GABA receptors! Haha, no really my favorite reaction is that of 2,4-dinitrophenylhydrazine and aldehyde sugars. Just a pivotal moment in my studies, so useful and so interesting, not to mention the relative danger of messing around with aromatic nitro compounds.

[tybo09]

Excellent answers all the way around!

Energetic reactions are great, for sure, but my favorite reactions are precipitation reactions. The first time I saw one was in high school and I've thought they were very cool since then. Unfortunately, I don't remember the particulars of the first one. I know it produced a beautiful yellow precipitate. I'm wanting to think it was a lead compound... Lead dichromate is a yellow lead compound, but I don't know if that was what it was.

[KillerDramon]

magnesium + fire + water :)

[iBO0M]

BRADY, YOU'RE JUST AWESOME

[tacoyum6]

@5:50 DO that!!

[Borrisbeaner]

rock's are very territorial creatures

[Zed1967]

My least favourite reaction is accidentally calling your girlfriend or wife by your ex's name, especially if you are being intimate at the time. Trust me, it's a very violent and dangerous reaction that usually results in solitary confinement in the spare room.

[thechapstick]

Is that phosphorus experiment the making of sodium phosphide?

[thehomette]

Calicheamicin, so awesome.

[SammyJay2008]

ah we were all waiting for Martin!

[99Chemicals]

What is the formula for the reaction of KMnO4 with H2O2?

[lexichronicle2]

3:22 :D nice.... nice.... proving even rocks care...

[Digadogup]

1:45 is the best :B

[MoneyAndPeople]

yeh, this didn't end up in my box.. had to come find it

[pagani8]

@MoneyAndPeople Yeah me too. Great video though, huh?

[Zahirsai]

I've always been quite taken with a simple undergraduate lab reaction, which is the reaction between nitric acid and copper (in the form of a penny). The copper (Cu) is oxidized by the oxidizing acid (HNO3) to copper II (Cu2+, if you will) which initially coordinates with nitrate anions (NO3-) to give this brilliant bright green color in solution. At the same time, the nitrogen is reduced to nitrogen dioxide (NO2), which evolves as this quite terrible looking brown gas, which is very harmful!

[Allisonesque]

My favorite reaction is the Briggs-Rauscher oscillating reaction.

[mrblisterfist]

A solution of 7.15 g of d-lysergic acid mono hydrate (25 mmol) and 1.06 g of lithium hydroxide hydrate (25 mmol) in 200 ml of MeOH is prepared. The solvent is distilled on the steam bath under reduced pressure. the residue of glass-like lithium lysergate is dissolved in 400 ml of anhydrous dimethyl formamide. From this solution about 200 ml of the dimethyl formamide is distilled off at 15 ml pressure through a 12 inch helices packed column. the resulting anhydrous solution----just kidding :P

[tomattosfutleimierda]

i love the new youtube shit :3

[chronos1002]

I get that you are using the reaction between the chiral amine and the chiral carboxylic acids to form a salt that immediately precipitates out of solution. I guess this is what would be called a recrystalisation reaction. But how do you then seperate out the different enantiomers. How do you know which "pom-pom" is which ? Or do you have to perform NMR or some other instrumental reading on each individual crystal and combine like with like ??

[jacarandaspoon]

@chronos1002 The chiral amine will bond preferentially to one of the enantiomers of the chiral carboxylic acid such that the crystal forming will only be one enantiomer the other will remain in solution.

[MrMichkov]

I´d love to see the red phosphor reaction. Sounds quite exciting to watch

[bigjohn756]

My favorite reaction occurs when a mixture of powered zinc and sulphur powder are ignited by a flame. I think it's beautiful! There is a brilliant yellow flame and billowing, pure white clouds. I used this stuff back in the mid 1950s to propel small, homemade rockets.

[gulllars]

My favourite reaction is iodine and ammonia, or rather the resulting nitrogen triiodide and it's decay. A very low initiation energy supersonic detonation with a violet plume and shockwave. The initiation energy is so low, you can mix it with sugar while it's wet, and when it's dried up it can detonate from a fly landing to eat the sugar. If made really pure, it is also the only chemical (according to wiki) that can be detonated by alpha radiation from nucelar decay.

[bigjohn756]

@gulllars I used to make a lot of iodine crystals and ammonia in my fathers basement. After generating a few pops every piece of metal in the room was very corroded. The smell made my parents stop the experiment; my "laboratory" was only about 10 feet from the laundry area.

[talshiarr]

Neil's favorite reactions are the ones he doesn't have to sweep or mop up off the floor.

[r3dited]

Awesome video ! All of you are the best story tellers. I'd rather watch you guys then anything else :D

[grndmstrjoe]

Stephen Liddle didn't favor a Uranium reaction? Surprising!

[Shmilli]

Wow, this was a great video! I specially enjoyed the chirality of the carboxylic acids ^^

[coldlogic1]

you guys talked about morhpine i was wondering about botox or other kinds of toxins that harm the body and why they do. do they relate to each other? such as venom from a snake or something that would make an exciteing video heh :)

[jeebersjumpincryst]

My fav (one of them) when I was a kid was potassium permanganate and glycerin. In a big hole drilled in a block of wood, with a cork hammered down on top.

Can you believe, they used to let me do this AT SCHOOL, during playbreak, and the class teacher asked me to do a demo outside during classtime. This was in the mid 80's, and I was 9 yrs old! Times have changed.... prob for the better, lol :)

Thanks again Brady and to all the Prof's, and Neil especially!!!

[OOZ662]

I swore she was going to choose a Boron reaction...

[buzzausa]

Definitely the Diels-Alder reaction. One of the greatest chemical advances of the 20th century.

[petokyo]

Okay, so now you have to show us the ones they talked about.

[Moshejetz]

can we see some of these reactions

[legochuckles]

I remember the chemical garden video. I wanted to make one too.

[raishisou]

246 likes and no dislikes... where are the haters? lol

[Superchickenman159]

lol, british ppl

[xMadSkillzx]

I just tried to look up "colicchio myosin" (hope I spelt it right) but can't find any information on the internet, any chance you could do a video, or send me some information? Many Thanks :P

[chemicaliser]

@xMadSkillzx There doesn't seem to be much info but the correct spelling is calicheamicin!

[xMadSkillzx]

@chemicaliser

Thank you for that, the correct spelling has got me a little more info :P

[BuickDoc]

I am surprised that no one picked the thermite reaction. To me, there is nothing more impressive to demonstrate so many aspects of chemistry, re-dox, chemical energy, etc.

My other favorite reaction is the Willgerodt reaction. Look it up.

[Cellogamer]

Half expected Neil to point at a pool of water and throw some K in

[culwin]

RnF2

[Infloresence]

Francium and Fluorine would be very energetic

[vusiliyK]

pi bond sounds like pipe bomb

[43932]

I love Pb(NO3)2 + KI or oscillating reactions 

[ijunkie]

Bullseye!

[dajwilkinson]

A mound of ammonium dichromate, heated at its top. Neat flameless volcano as the compound oxidises/reduces itself to chromium (III) oxide, nitrogen and steam.

[TheMasterminding]

And what happens when you pour liquid nitrogen into water?

[DeltaPhi79]

@TheMasterminding People dumped a whole bucket of it into a pool. Makes a LOT of fog.

[CrackedWhiteradiator]

Great editing :D

[periodicvideos]

@CrackedWhiteradiator thanks... always like a bit of edit appreciation! :)

[kardredren]

"bucket chemistry"... I had to double take that part, I thought she said something entirely different :)

[coolliger]

Great video!

[zapo147]

strychnine and the human body

[puretroubleman]

I like the Ammonia Fountain reaction. 

[ice7771]

"Hey, know any good jokes about Sodium?" "...Na"

[TheMasterminding]

What happens when you react hydrogen peroxide with potassium dichromate?

[leosedf]

Has anyone else noticed the poofy thing above the mains plugs at 0:06? Or is it just me?

[1p2o3i]

@leosedf It stares INTO YOUR SOUL! xO

[ManganistanDraselny]

And what's Neils favourite reaction???

[Jiddy12345]

Neil has no reaction

[awesomejoe12]

I want to see the dangerous one!

[spotlightman1234]

@patrick2586 lol ammonium nitrate + aluminium powder + powerful gun = boom.

[Phacias]

Where is Neil??!

[TheChemlife]

what's the name of all the chemicals used in the crystallization reaction. if i can find out what it is i want to make a video of it.

[Shannariano]

2:00 I'd really like to know something more about that reaction... could you make a video about it?

My favourite reactions are, maybe, the Grignard reaction or the vulcanization of rubber

[Ormaaj]

The high-speed of the barking dog @0:36 is awesome! I don't believe I've seen that footage elsewhere.

[periodicvideos]

@Ormaaj you sound like a dedicated fan... it is indeed new footage I had up my sleeve!

[MrValzen]

@periodicvideos

If its from the open day might be able to see myself

[runnybabbit12]

@periodicvideos what is the name of the reaction with the white phosphorous, sodium and potassium that the nuclear guy was talking about?

(i'm sorry i forgot his name)

[BarneySaysHi]

Heating iron powder and sulphur in a testube over a bunsenburner, then smash the tube as the ironsulfide had become rocksolid, then drop the ironsulfide into hydrochloric acid.

That was the ONLY time our teacher allowed us to actually break a testtube. The smell that followed was a good reason to open the windows, even if it was done in a fumehood...

[spotlightman1234]

@BarneySaysHi when ever i work with H2S i always worry i'm going to lose my sense of smell, then die of H2S poisoning.

[soundofgeek]

Gotta say, reacting P and NaK directly sounds crazier than any of my high-explosives ideas.

[shidoink]

very good question brady! great video.

[periodicvideos]

@shidoink it was a viewer question, not mine! :)

[shidoink]

@periodicvideos right, but you picked it. props to the viewers as well

[Skindoggiedog]

Orgasm.

[bigbowser101]

One of my favorites that I've done many times in Organic Chemistry II because of the many ways to do it is the combustion of nitrocellulose.

[aeroscope]

I want to know more about the rock's biological defense

[thejenyus]

cool

[un2mensch]

My favourite reaction is the complex organic self-sustaining reaction we call "life"

[Pianoguy32]

Right, bnow i want to see a video on the phosphorous-sodium reaction that is dangerous.

[BarneySaysHi]

@Pianoguy32 I'd sure like to see what happens yes.

[DevilMaster]

My favorite chemical reaction is the one where you ignite thermite by mixing blur with bl... uhm, glycerol with potassium permanganate. :-)

[CapPicard]

I like when y'all broke that vial of caesium into water. *boom* :)

[divineobject]

Thank you so very much! These videos are so useful and entertaining. You guys are the best!

[NomadandtheSun]

So the question is: what is Neil's favourite reaction?

[02151d14]

@NomadandtheSun yea, where's Neil?

[Telamond]

The Wacker process is my favourite one. Not because it's pretty, but what you make and what the waste is.

[oOoxelAoOo]

The Briggs-Rauscher reaction is quite fun.

[edheldude]

Thermonuclear explosion

[tkermes]

Molten Potassium chlorate and gummy bears! They turn into gummy bear flares.

[hanzithaking]

nuclear reaction? anyone?

[Rigorvitus]

THC in my brain

[clearmenser]

Oh yea! Nothing like asking experts about their favorite technical thingies. Just look of delight on their faces. So good ^_^

[rossexton]

Iodine Clock - absolute classic.

[CIoudFire]

are there videos of those reactions they were describing?! i so want to see that crystallization reaction that he stared at 40 mins for!

[periodicvideos]

@CIoudFire I put a few links in the description but many of them we have never done, including Pete's crystals...

I've told him we should do it, though he did say it can take a VERY long time to prepare...

I'll keep hassling him!

[QwoPhasaArius]

@periodicvideos I want it too!

[hedleypanama]

@periodicvideos the nurdrage and thunderf00t are getting fun doing several reactions too

[EFox2413]

@periodicvideos please do! I'd love to see these reactions performed. Flawless editing as always!

[SpookyFan]

@CIoudFire Same here.

[Eldejot]

@CIoudFire I second this.

[colinstu]

@CIoudFire hell yeah! That what sounds amazing!

[taeke18]

Put 2 buckets 1with HCl and the other one with NH3, next to eachother and you will get sort of spirits

[phayz9]

loved the ending of the vid perfect way to end it

My Favorite reaction has always been sulfuric acid and sugar

[PianoKwanMan]

Liquid oxygen between magnets :)

[ThatKidKnows]

potassium chlorate vs Jelly Babies :P

[uut0]

Potassium chlorate and sugar.

[invinciblemode]

A simple Mg + HCl reaction get's me high.

[pepsibookcat]

I'm surprised Debbie didn't go with a boron reaction!

[periodicvideos]

@pepsibookcat me too!

[Ralphgtx280]

@pepsibookcat combustion of trimethyl borate would suffice as a beautiful reaction with boron (as is the combustion of amorphous boron but sadly thats rarely demonstrated )

[TerenceHorsman]

under 300 club

[kanjitard]

Potassium iodide + lead nitrate

[jablair51]

I'm disappointed no one said Fischer Esterification. 

[Horathgar42]

@jablair51 :P

[jablair51]

@Horathgar42 More specifically, if you do a Fischer esterification of isoamyl alcohol and acetic acid you end up with Isoamyl acetate. Also known as banana oil, one of the best smelling things on the planet.

[Horathgar42]

@jablair51 Yep, I did that in high school. Its also very very similar to the bee attack pheremone, gotta be careful about that.

Lately i've been dealing with keto-enol stuff, in Ochem 2. I really am fascinated by the electron shells dealings in benzene with all the Electrophilic Aromatic Substitution stuff myself.

[machewbaccas]

These guys have made me realise science is going to kill us all..

[TheCaptainLulz]

NaK + P = Death Phosphides are some of the most toxic chemicals known.

[EyItsKimron]

Bucket Chemistry <3

[Laviii11]

FUCKIN ELEMENTS

[Laviii11]

@Laviii11 HOW DO THEY WORK

[periodicvideos]

I've put links to some of the videos featured here in the extended video description.
