Dehydrating Sugar by Sulfuric Acid (Mad Physics)

[pheonixmon1]

IS IT EDIBLE

[limerick2090]

Haha, that beaker is ruined :)

[warmonger12z]

@limerick2090 you'd better believe it's ruined ... i work in a school, and whemever someone does this, whatever it's been done in - test tube or beaker - goes straight in the glass bin

[EvinIsPro]

looks hot

[codeythesilent]

Try cracking an egg and put that in a beaker with sulfuric acid.

[martinsdiana93]

And when scientists are done they stare at the crap they made and they're like «Who's gonna clean that?...»

[rolingpingu]

Isnt the leftover Carbon...thus meaning diamond...somehow?

[sgreen71778]

@rolingpingu Diamonds are made of Carbon, but carbon under EXTREME heat and pressure, usually miles beneath the surface of the earth.

[FireFlamesrocks]

holy shit

[Monkeynuts502]

so, sugar + H2SO4 = Carbon?

[Tigerkos]

@Monkeynuts502 Yes, The sulfuric acid literally "sucks" the water molecules from the sugar turning it into carbon. Haven't you ever wondered why sugar is called a Hydrocarbon? It consists of Water(Hydro) and Carbon. So if you take water out of the equation then you have only Carbon

[soylentgreenb]

@Tigerkos Slight correction; sugar is a carbohydrate, not a hydrocarbon.

[scorpserpent]

@Monkeynuts502

H2SO4 dehydrates the Sugar..which has a general formula of CH2O..so the dehydration process takes away the H20..you're left with C

[kefer123622]

It looks like if you put your hand in it and took it out it would be nothing but bone.

[rustyjoxz540]

stick your hand in that shit!

[LilMichaelJoe]

fail

[Schizophrenic0]

nice

[LabRat6619]

They don't like each other much!

[Sysio]

wooohaaa

[Adrealist]

Finally the word is introduced to how Airplane food is prepared. Done in .3 seconds.

[CPGloriajimmyROBLOX]

jesus!

[WhelenVTXR2]

Simply put, the acid turns it and the sugar into carbon.

[billytalentrocks345]

Liquid liquorice! :D

[bbnnq]

. . . Or pie? =/

[bbnnq]

Tar?

[bestSVMS]

is this sped up?

i havent seen it happen this fast

[Woodsyone]

Dosnt seem to be.

[Sillybillydilly]

I have never done this, but this is probably 97% H2SO4. Other videos might be using the 62% chamber/fertilizer grade, or 74% Glover tower, or even the 33% lead battery acid. Those already have water, and are nowhere near as vigorous. If the 97% still doesn't react this fast, it might be that he has the acid preheated, or the sugar is in a very fine form with high void space, or even that he uses heated oleum (106% acid, extra SO3 dissolved.) But you should be this scared of this on your skin.

[Sillybillydilly]

I just noticed it - he has a solution of sugar AND some undissolved sugar. As soon as the acid hits the water, it starts boiling, and the water turns black. That's why its so fast - it reacts with dissolved sugar syrup to start with, and not the solid sugar, and gets hot very fast.

[maniacwithagun767]

an exothermic reaction ; )

[TheDrkKnght1988]

WHOA!!!

[shitozeruel]

dangerous...

:D

[Fiddlesniffs]

haha I got a huge waft of steam blown at me the day I tried the elephant turd experiment.. goodness me does it smell bad!

[dosomethingwithme]

what its done when you put in finger in the black thing ?

[PureRebelM1ko]

you i'll get a cookie.

or maybe NOT.

[Stephennnc13]

ASTRONAUT FOOD!! kidding....

[AlessandroAUS]

Chemistry is just applied physics, or so says my physics teacher. Then again, my maths teacher says physics is just applied maths.

[berndawg123]

its goes like this... Biology is chemistry, chemistry is physics, physics is math, and math is boring

[MrRenanwill]

@berndawg123 Dont say that. It hurts =(

[Ohnoezhumenz]

Physics talks about why and how stuff happens in context with; radiation, movement, gravity, speed, momentum etc.

Chemistry is all about how certain compounds react to each other. As is very well shown in this video.

[alpha492]

no your silly... Take any intro to physics class

It is the most basic science I could get my art of physics book from like 3 years ago and give you the textbook definition but I dont feel like it...

[tugfngjfuvj]

/agree 100%

[dhwanitchem]

Idiot No PhySics only CHEMISTRY

[miiiikez]

physics and chemistry are linked together

[DAssAD1985]

physics and chemistry are definitely NOT linked together.

[miiiikez]

whut?

they both study matter and its behaviors

[DAssAD1985]

In chemistry, elements are linked together what gives a product with other behavior then the edukts. and it's a not reversible reaction.

in physics, the educts remain the same.

[liam7morris]

what about nanotechnology then? that involves both

[Deel2506]

the loss of a flask right there :D

[Timerider]

That's what I was curious about. Can that be cleaned?

[luisz122]

Caramba ! Parece pixe preto quente.

[JadenYugiGX]

Actually it should be "Mad Chemistry" :) LOL

[walkandlookup]

indeed U R right no phisic

[RknapZ]

Nice videos though.

[gomeras40]

We watched this in Science

[RknapZ]

You guys are dumb. That's not Physics, that's Chemistry. Why do you call yourselves Mad Physics?

[pinkytm1]

I got into that discussion with my chemistry professor and he said its really all physics.

[Tiberius0476]

Sadly, the fumes are all water.

The black stuff is nothing but carbon.

[rawkiche]

where did the carbon come from?could u plz write a formula of the reaction? thank you!

[Tiberius0476]

Glucose is C6H12O6

In this reaction, H2SO4 (sulfuric acid) is just a catalyst, meaning it helps the reaction move forward without being changed.

C6H12O6 + cat. H2SO4 -> 6 H2O + 6 C

The heat vaporizes the water, and all that's left is carbon. The pure, black carbon is tough to clean, too: no functional groups...

[captgunner]

i feel sorry for any person trying to get high off of the fumes =[

[M3T4LH34D812]

vitamin D regulates levels of calcium and phosphorous in the blood, so logic suggests more vitamin D = greater levels of the two substances, combined with carbohydrates in a closed system under pressure,(eg: dogs which don't sweat) metabolic processes should result in sulfer compounds, which in turn reacts with the sugars giving muscle and epidermis their distinctive hues and functions, which to the best of my knowledge has yet to be fully understood, however...

[M3T4LH34D812]

combined with the reactions related to vitamin D and in rare cases anti-D immunoglobulin, could offer insights to a myriad of diseases, related to the rh system, immune reactions such as autism, hiv, aids, osteoporosis, rickets, jaundice,kidney stone formation, predisposition to skin cancers, etc...

[gwarsux]

so sugarwater+suferic acid=rising turd of doom!

[captgunner]

yes it is, but that turd is pure carbon

[M3T4LH34D812]

Is there a way to now reconvert this carbon back into sugar ? what happens with hydrogen peroxide and or chlorine and carbon ?

[Sillybillydilly]

Carbon is reactive with nothing at room temperature, but it burns quite well in air/oxygen at 600C to form CO and CO2. You can recover the water from the sulfuric by distillation, break it into hydrogen and oxygen, burn the carbon in oxygen, and react the CO and CO2 with hydrogen, to form basic organic molecules. From there on, it's wild organic chemistry. See gluconeogenesis for how the body builds glucose.

[slither888]

Physics? How about chemistry??? Anyway looked like the acid wasn't too concentrated; it flows like syrup at 98%

[ReverendSyn]

Does that generate heat? Looks like it with all the bubbling and smoke.

Certainly doesnt look like something one would want to touch while it happens.

[LtChicken]

it gets extremely hot and no you would not want to touch that black gunk.

[somervillefire]

i think the smoke is steam. i think what happens is the acid breaks down the sugar into H20 and carbon (the black stuff). the reaction produces a lot of heat, so the water boils. Please correct me if i'm wrong.

[Gliu1]

Yes, that's it. Moreover, the sulfuric acid here is highly concentrated, as you can see from the speed of the reaction.

[joshie92]

It is called an exothermic reaction which means it produces heat.

[abarbar06]

jeeze was that like pure sulfuric acid or what?

[ReverendSyn]

Venom?

[rotterdamterrorcorp]

seriously lol

[twinkietorture]

remember there is a difference between h2so4 and h20

[douro20]

A classic example of dehydration of a carbohydrate by sulfuric acid. The reaction produces water and carbon.

[jayems213]

Looks like a dishwasher's nightmare if you ask me.

[farmerloon2]

lol

[theuncanspan]

tht is soooo 9th grade (coz h2so4 is a thirsty acid nya nya nya ) thnk god i graduated mwah ( kisses sky)

[bano363]

a thirsty acid? sounds like it was dumbed down for you hahah

[theuncanspan]

wt u mean?

[theuncanspan]

ah tht am a stupid fuck no man its dumbed down to the rest of the bullshit students LOL

[FelixB91]

Now that was a powerful reaction:P

[toptencd123]

it went from sugar to poop liquid

[lampo85]

i did that before in chem lab, that shit stink to high heaven

[cheeseboat15]

too much H2So4

[nirvana1273123]

dude...how te hell did u clean that up....anyways kool vid its awesome

[BassistOfTheFall]

Sweet!

[yaamahdi]

Now drink it.

[madphysicsdotcom]

It sort of has the same texture as a nice soft brownie. The only difference is that it's made out of sulfuric acid. We tried to convince some people to taste it, but we haven't had much luck.

[yaamahdi]

hahahahahahaaaaaaaaaaaaaaaaaaa­aa.... that's funny.

Offer a shot of hydrochloric acid to wash it down. maybe that'll change their minds... lol

[twinkietorture]

is it dangerous? to eat

[linuxpowerification]

@madphysicsdotcom

No shit :D

[KevinBronxx]

koooool

[XYJetta]

Awesome Vid.

[asdblue333]

that was cool
