V 30 - colour changing dry ice -Farbwechsel durch Trockeneis

[CatullinaBfa]

Could you tell me the material you used?

Könnten Sie mir sagen das Material, das Sie verwendet?

[717shaye]

I GOT DRY ICE AND SOAP.... WIERD BUBBLES...... IN MY TEACHER CAR!!!!!!!!!! SHE OPENED IT AND THEY ALL EXPLODED

[Thunderhead38]

Soap!!!  FTW!!!

[mik32120]

Wieso haben wir NIE sowas im Chemieunterricht gemacht?! Kein Wunder, dass ich da immer eingeschlafen bin...

[maxtrata]

XD 

[Seto0019]

BTB is Bromthymolblau(german) and Bromthymolblue in english(i think)

[Chmielok]

Now I understood how important languages are. I can say Hello! in 3 different languages!

Good morning, Guten Morgen, Dzień dobry.

And BTW what's BTB?

[engelspopo]

WO BEKOMMT MAN DENN TROCKENEIS HER?

[todmanzi5281]

mhmag jemand quatschen bin ne ganz liebe aber irgendwie total einsam im moment

[skate14z]

those look like variations of Bromothymol Blue

[metamaterial]

Well, one of them certainly is.

[skate14z]

yes i know but they look lik variations of diff colors but ik theyr not

[metamaterial]

The one labeled BTB is probably the dye in question. The others appear to be soap, litmus, a universal indicator composed of several indicators of various colors and pH regimes, and water.

[skate14z]

i know

[metamaterial]

Ah.  Jolly.

[heyaanimerocksheya]

What is the chemical name of dry ice,

Co2?

[dracotel]

dried ice is dried CO2 yes

[dracotel]

not dried CO2 but frozen CO2

[danz409]

would make a NICE halloween prop

[HappyIsWhatHappens]

I t is just Bromothymol Carbon Dioxide indicator. It changes colors for Carbon dioxide

[SavageArms357]

Cool.

[Tragon96]

A WORM GET OUT OF SEIFE

[ninomhe]

thats soap

[Ratznium]

@Tragon96

This sounds like the latest Internet meme.

[carnage98kill]

you really can afford to Fvck things up like that,dont you

[quadzilla459]

i dont get it

[utsavman47]

compare the colors of jars of

0:08 with 1:00

[KittieKatGrl]

i wonder what would happen if you mixed them?

[citymoon8000]

i wonder what will happen if he drink it LOL

[mathern333]

seife was puking

[cheese4690]

u can get dry ice at Boc Gas & gear for around $13 per kilo.

[Cincysoccer18]

where do u get the dry ice???

[madzia16amor]

Can someone explain to me may experience what is there doing what they are added to solutions, please

[BirdValiant]

The beakers are filled with some sort of pH indicator, except the ones on the far right and left. Dry ice is just solid CO2, carbon dioxide. Instead of melting and then evaporating, dry ice turns to vapor directly, in a process called sublimation. When CO2 is added to water, a very small amount combines in the reaction CO2 + H2O --> H2CO3, which forms carbonic acid. This acid lowers the pH of the solution, changing colors. Unpolluted rain is always somewhat acidic due to it falling through CO2.

[BrEaK1T1N]

@Cincysoccer18 buy it from a store....but u have to be at least 18

[kingdomhearts804]

@Cincysoccer18 i think u can buy them from ukrops

[Eversmann1000]

@Cincysoccer18 Ice cream man

[Berry242492]

wow die seife geht ab!

[kipdif]

how do you make dry ice

[XxX4musica5lsteveXxX]

freeze carbon dioxide i think my mom uses it to freeze body parts in patholodgy

[jesusboy36322]

you have to freeze carbon dioxide, but how do you concentrate the CO2 in order to freeze it?

[31337Lisper]

You just freez it. Think of CO2 as if it were water steam, you just cool it till it turns into water, and keep cooling till it becomes ice.

[iwan0t0smith]

thats not entierly true,

first they compress it into a liquid, then rapidly expand it so it cools and forms a snow. Then they compress it into a hard ice.

[BirdValiant]

As a by-product in ammonia and hydrogen plants, where methane is converted to CO2;

From combustion of wood and fossil fuels;

As a by-product of fermentation of sugar in the brewing of beer, whisky and other alcoholic beverages;

From thermal decomposition of limestone, CaCO3, in the manufacture of lime, CaO;

As a by-product of sodium phosphate manufacture;

Directly from natural carbon dioxide springs, where it is produced by the action of acidified water on limestone or dolomite.

[happap123]

@kipdif  uh, you don't make dry ice. you buy it at safeway.

[halogenosycalcogenos]

good video ;)

[Frresh123]

i wish i haf dry ice...cO

[funny20101]

Milk makes the best bubbles for some reason (with dry ice). It beat dish soap and it beat other things we tried. I think it might have to do with the extreme cold reducing bubble soap's effects. Try milk.

I have no clue about the color changing yet. Also, a light stick in the water tub filled with dry ice in a dark room is a treat. Lasers .. always bring lasers but don't trust the kids.

[dayharrison]

this is random but where do you get dry ice

[funny20101]

I buy mine from Safeway, a grocery store. In the past, I've bought it from Crystal Ice, a Sacramento ice seller. I know you can also get it from some Ice Cream shops that use it during shipping. If you search your local phone book, somebody probably sells "ice". Ask them where to buy the dry variant. Don't touch your tongue to it.

[slateflash]

I thought btb changes from blue to yellow, bt it's gone a bit orange. Someone epls explain.

[piro556]

Are you dropping dry ice in it?

[mskerripa]

whoa awesome

[hareoli]

The 5th one is the odd one out ITS GONE MAD!!

[Renegade17441]

I think it has soap in it, that's probably why?

[thetom69hotmail]

What are the caps you put in ?

It's pretty impresive, I'd like to do it once !

[mynameeminem]

upi shoul have lit the ligh blue bubles on fire

[hyperactivepenguin12]

here are the liquids from right to left

water;universal indicator;btb;soap

sorry I dont knowwhat the third one is

[Twyrix]

The third one is lackmus, a well-known pH indicator.

[wsmith68]

Known to english-speakers as "litmus".

[BellENDwanKer]

hahaha cool!

[hckygymnastics]

Hi so cool. What are the liquids you used??? I am trying to do this as a science fair idea.

[somedudeandacomp]

they aren't changing colors... looks like food coloring, and soap in the last one :P

[TheElvenChild]

hhaha the bubbles..

[urbandecayxx]

what are the 5 liquids?

[leedorfer]

i only now right is soap with the foam is soap and this on the leften site is water

[WiiMiiCreator]

i think they added food coloring...

[smokyabram]

it says it right at the top of each one idiot.i hate when people act stupid for no reason

[davegsucks]

soap, bromothymol blue, litmus, universal indicator and water.

[elgranto7]

or food colourings

[grant2053]

sopey water + hydrogen gas = a big column of sope bubbls + match =cool

[lunavixen015]

it's not hydrogen, it's carbon dioxide

[grant2053]

i know nvm you have to know what im talking about

[lunavixen015]

the thing you mean is methane, hydrogen explodes, it doesn't burn

[elgranto7]

methane is just explosive lol

[Ghostgal11]

the one on the far left was soap mixed with water. ive done it before so i think i know :P

[onlyinternet]

i like this think

[x0x0uLLi0x0x]

that's cool..

i like it..=D

[84dixienormus84]

some more chemistry for yall:SUGAR+WATER=SUGAR WATER

[ReXtOn07]

and water + ice + 5min = cold water lol

[foxman430]

sweeeeeeeeeet, thats awesome!

[efrenjo]

What is that SEIFE substance? CO2+H2O produce carbonic acid don't they? So they indicators are reacting against a decreasing in pH...

[Netexperimente]

"Seife" is the german word for soap =)

[efrenjo]

Thanks!!!

[gchhour]

there was one vi where this one guy took the soap produced by dry ice and smushed it it wass cool!

[Eversmann1000]

@efrenjo Nerd lol

[UberLifeTroll]

@efrenjo SAIFE is what he purposely drops in the showers ;)

[Netexperimente]

No! On the homepage, shown at the end of the video, you can read the explanation now in english too.

Greetings, Netexperimente

[Xenodius]

Let me guess: Those are pH indicators, and the ice is impregnated with bicarbonate or some other alkaline?

[eleanorausrex]

wow that looks fun

[rushevoracer]

probs caus you a lot od discomfort and you will be burping all the time

[imyourpally]

what would happen if you ate liquid ice?

[lanswipe]

because of the extreemly low temperature it would freeze off your insides ripping the skin off as it went. NOT a good idea.

[GakkiSai]

You'd die.

[matts417]

it would burn like a mutha fer.I had some on my hand before, and it burned so bad it took about 5 days for me to get feeling.

[mciryan]

liquid ice? liquid ice is water.

this is dry ice. frozen Co2.

[GodLike66669]

WOAH. not cool

[blankplanet]

a freaking dexter's laboratory!! amazing!

[aemreunal]

wow

[thebulletproofboy]

awesome
