  • "I didn't expect it to go like that...Some of it's gone green!"

    I have a feeling I would have learned a lot more in chemistry if I had this fellow as a teacher. :D

  • Egg I'm liquid nitrogen

  • His wallet chain?

  • In regards to using HCl, you can use white vinegar instead to remove the shell really nicely. Its quite remarkable really that even with the hard shell dissolved, you can pick up the egg and it will still keep it's form. It's quite squishy and feels like it's about to burst in your hand, but the membrane is stronger than it looks. The egg also expands due to osmosis! Give it a try (but give it several hours, perhaps leave it overnight). Easy to do at home.

  • IT'S HIS PIMP CHAIN!!! HE GETS ALL THE BITCHES!!!

  • The very fact that he stuck a pen in the egg proves he is the best professor!!!!

  • Not to contradict the Professor, but, Being a Professor of Art History, I must point out, that it is the Yolk that was used in Egg Tempera paint, such as Bottecelli used. The Albumen (whites) was used extensively in early Photography, which along with Silver Nitrate was used in one process (too long to fit here) for print paper, and one for glass negatives, which involves the Albumen and silver nitrate salts. The mixture is a colloidal mix to coat the glass negatives. I can explain paper later.

  • Blargh... ur pen!

  • Amino acids = Silly Bands. Think about it.

  • ....How can you dislike these videos? You have the worlds greatest Professor with the worlds greatest hair!

  • He's so cute! <3

    

  • Cook show with professor. Every thursday at 9 o'clock.

  • Wasn't even trying and he perfectly cooked the egg. Never ceases to amaze.

  • u have 2 let it cool down 1st

  • so... is that egg-in-a-hydrochloric acid edible?

  • Egg Sandwich anyone 

  • Anyone else feel like a hard-boiled egg now?

  • wow, im quite surprised how many interesting facts you can learn from all these videos

  • Eggs taste so much better BEFORE being cooked. :)

  • @1RadicalOne ... but you can get some deadly disease.

  • Not if you prepare them correctly.

  • Lol at the lab. I had benzocaine washed out of my mouth in the technicians room at the back haha!

  • um just fyi i did the egg experiment with conc. hcl a while back and it absorbs the acid to an extent and if you let it sit on any surface it releases hcl gas and it reacts with things it ate right through aluminum foil that i sat it on

  • 3:54 lo0l

  • this guy is so cool

  • proper boffin him

  • At 0:28, you said that the bubbles are carbon dioxide. Why aren't they hydrogen?

    Ca2++2HCl-->CaCl2+H2

  • CaCO3 + 2HCl → CaCl2 + H2CO3 and 2H2CO3 → 2H2O + 2CO2

  • because the egg's shell isn't made of calcium metal. if it were, it would react with air itself. also, your equation for the reaction of calcium isn't balenced correctly

  • i was wondering because a teacher told me that sulfidric acid H2S is very, very dangerous and could kill you in a concentracion of 6 parts per million?

  • Sulphuric acid has the chemical formula H2SO4, not HS2. That's Hydrogen Sulphide. But yeh, Sulphuric acid can be very dangerous even at low concentrations.

  • im sorry i meant hydrosulfuric acid (in spanish the name is acido sulfhidrico), and i was wondering, does it have to be in aqueous solution to be acid?

  • I really want soft boiled eggs now......

    also @ asdasdasdasdasdas98 : I wouldn't really say so.. I hate salad fingers and I love the prof.

  • He reminds me of salad fingers lol

  • Actually when you heat proteins they denature, they change their shape and lose their functionality.

    I don't know for sure if that's what changes the colour of the eggwhite but I always thought it was.

  • I learned to boil an egg!

  • sick burn at the end there professor.

  • Dear god he's adorable.

  • the old guy is so adorable!

  • ye i agree to bless him

  • ha ha ha your right!!!!

  • i dont really know if im the first person to notice this but dont you think this guy sounds like salad fingers?

  • Yes, creepy

  • Comment removed

  • This guy is so Gangsta!

  • WORD UP HOMIE!

  • omfg this guy is soooo cool i wish he were my dad...LOL

  • this dude is bad ass

  • The proffessor always has a pen handy may it be used for writing or....poking an egg?

  • th coolest professor !! period

  • Hello, I write from Panama. Here in Latin America acids are used to cook. Ceviche is a special meal of seafood made with lemon, lime or bitter orange. Here, most of the people believe that spice makes the "magic" of cooking raw seameat, but the acid does it.

    Also we "cook" quail eggs with lemon, they look like boiled eggs (I suppose because it is a not so strong acid and they are smaller than a chicken ones).

    The main problem is that some bugs (bacteria) can live in this kind of environment.

  • @hedleypanama make a video about it.

  • well look what happens when i stick my pen in it..... fucking classic......

  • This guy reminds me of Doc from back tot he future :D Seems like a real nice, easy to learn from guy.

  • nice guy

  • "Even if you haven't..."

    Ahaha.

  • if you imagine a professor, this is who i see =] a cliche science scholar..

    good work!

  • Yeah sure baby!

  • I would like to chill with this guy.

  • lol

  • oh, so that's how you pronounce amino in "amino acid" I always pronounced ah-me-no acid.

  • Ah, but do you know how to pronounce Aluminum?

    Al-you-min-ium instead of a-loo-min-um

  • Such a delightful man. :D

  • When I did a similar experiment to this back in school, we used vinegar to dissolve the eggshell.

    As for cooking with acid I've got no experience

  • WHERE WE'RE GOING, MARTY, WE DON'T NEED ROADS! x

  • Happy Easter! Watching this video was the only thing I did today that was remotely related to Easter.

  • That hairs badass lol thanks for the info man love science

  • this looks like Richard Simmons in couple of years!

  • I remember doing a project like this when I was a sophomore._.

  • I'm in love with your hair.

  • he poked the egg yolk with his pen!!!

  • or even the PTOV Team

  • Happy easter to TPOV Team ;)

  • This woman is a real buzz kill on Easter!

  • it reminded me abt eating eeggss..

  • I agree, but what, exactly, does that have to do with the science of Easter Eggs?

  • Thats great, but what does that have do do with the video.

  • fake? what part?

  • PSEUDOSCIENCE FOR CRETINS!

  • Wow...that looked yummy at 7:37

  • Acidy eggy hair....so thats how he gets it so fluffy! :D

    I leant something, great video.

  • easter is about god not fucking eggs b otch

  • Very true idntexst, perhaps he should have put god in some acid...I wonder what he's made of...

  • i bet you would do that ...i guess everyone one likes their sin instead of at least respecting god on easter one of the hollyest days of the year.

  • Easter is about chocolate dude...you know the easter bunny...hello? What's god gotta do with chocolate?

  • hello enstein i mean the hair u no? i bet he loves those ROUND eggs lol you no how he holds to at a time and loves to feeeeeel them?

  • Vid is awesome as always!

    Space Box add on the right is absolutely annoying and making me come less to youtube...

  • aww i like him, hes cute

  • we love eggheads!!

  • thank u 4 the science lesson professor

    i never even new this thanks dude

    R

    O

    L

  • HE LOOKS LIKE EINSTEIN....... :l

  • Trust me, this is no coincidence.

  • a changing of the conformation of the protein molecule?

  • I forget what is it called when the proteins in the liquid yolk turn white from being heated? Anyone know?

  • Denaturation?

  • YES! thanks.

  • pensioner

  • awesome experiments, professor! thanks for showing us :D i want to try now.. first thing i'll need is an egg, next thing i'll need is hdrochloric acid.. diluted, i suppose.. lol thanks again, professor- you ROCK!

  • Great video professor.

    When did they let you out last?

  • The Professor needs a long vacation

  • AFRO FTW :D

  • haha +1

  • Jei har aids, modern klikker for faen

    du er en dildo. javla mongo

  • that is frekin amazing!

  • Lol I've been taught by Poliakoff. Lengend.

  • You've got to be kidding me, LOL

  • my grandma has the same hair

  • AWESOME!!!!

  • also, when you get to this age you can actually hide your own easter eggs.

  • *And* you only need one egg!

  • Why am I watching this?

  • idk why?

    also good vid

  • I'm thinking the same thing LOL

  • Thanks. Good Video!

  • He's funny. Though i know of all that already but it was still really informative, lol.

  • it takes him a very long time to say very little

  • i fell asleep.. this is guy is funny but his voice is like monotone and i just dropped

  • hes rite

  • It's better to use acetic acid to dissolve the egg shell, but it takes much longer, however the membrane is left untouched and you can demonstrate osmosis by putting the membrane in water and syrup

  • Thought it was nana at first

  • Ugh... I tried to pay attention, but it was in one ear and out the other.

  • [Chunk o' Mammoth]

  • [Murloc fin soup]

  • Very peculiar man, isn't he? Funny and informative.

  • me too!

  • It's not that they suck at jokes, it's just you're to stupid to understand them.

  • typical nerd answer, gg

  • nice hair

  • he Is  very clever man.

  • what?

  • Amazing Video!

  • we watch all these videos in chemistry

    lovez them.

  • Chemistry and geochemistry make me happy

  • hes hot

  • I also like Chemistry...hoping to go into the line of science...epic hair btw

  • Luigi's Mansion called, they wanted their professor back

  • XDDDD I agree x]

  • HE LOOKS LIKE A GIRL!!!!!!!!!!

  • very interestant video..(i am chemist ) thank you

  • glad you liked it... we've done 159 others you can check out also!!!!

  • this is very cool. is this the nottingham university?

  • Sorry i just had a really dumb moment, i couldn't remeber which group Calcium was in, is it group 2 , so that it would lose to electrons to 2 separate chlorine atoms?

  • 3:54 lol

  • He sounds like salad fingers :D

  • .. when he sticks the pen in it. LOL

  • Interesting but I wonder the same thing

    Is it safe to eat an egg done like that ?

  • this is cool really interesting!

  • is it safe

    is it safe ?

    is it safe :-) ?

    ;-)
