Liquid Nitrogen Fun with Science Bob

[slavecake]

At my school we set of a 2 liter bottle with some water and liquid nitrogen put the cap on and BOOM the shock wave pushed me back

[123killaification]

1:20 Leidenfrost effect

[devilzshack]

I've been infatuated by liquid nitrogen ever since saw the villain in Terminator-2 freeze...

[2000gmod]

LOL

[khijasmith]

you have some great stuff here

[darkgothyoda]

don't forget the leidenfrost effect

[MrBUSABAZZ]

Ummmmm, so why do you wear a protective glove on one hand, yet you use your bare hand to transfer the Nitrogen? o.O

[cowgirlpride14]

where do u get luiguid nitrogen

[baseballrocks538]

@cowgirlpride14 You can't. Also liscened professionals can get it.

[mattj4554]

[Makargo123]

whats smeagul doing with liquid nitrogen! >:O

[cinci299]

Hey Bob , I was wondering... I was watching How to make a lava lamp the easy way. I have a way to . Water in a cup. Then Oil . Then you put salt and then the salt will carry the oil to the top giving it the effect of a lava lamp. And here is my question. Very simple. If i don't have food colouring can I use like a coloured marker or juice to colour it . By the way love your videos. Keep em coming :)

[ScienceBob]

@cinci299 Somw markers will probably work, but others will not color the water. Food coloring is very readily available and works best. Hope that helps.

[cinci299]

@ScienceBob Thanks this did help.

[Uuppi]

Science Bob sounds and even looks a bit like Edward Norton

[dizzydompie]

Leidenfrost - effect at 1:21

[1andrewmark]

this is why i like science the most

[legoreveiwer360]

you said you dont need any of the fancy dry ice stuff dry ice is cheaper and you have to be a scientist or a dotor to buy liquid nitrogen in england

[LankyFaLife]

has anyone else wandered if anyone put their hand in liquid nitrogen ???

[Soulsphere001]

@LankyFaLife

I hope not.

[CDchoreoz4u]

thats amazing AGAIN AGAIN AGAIN!!!

[funnyangrykid]

and thats Part of where the "Chryo-Stasis" idea in movies came from.

[jprav65]

Where do you get liquid nitrogen

[yellowbana29]

if you make the glowsticks glow, put glowsticks in ,then out, and let sit, the glowsticks will glow again right?

[freedomchaser2402]

how much pressure is needed to make liquid nitrogen

[jesja1000]

bob nyee the science guyyy....bobb nyeeee the scieenceeeeeee guyyyyy...bob bob bob bob bob nye he science guyy!!!!!!!!!!!!!!!!!!!!!LOOOO­OOOOOOOOOOL

[AJLOVESLILY]

you can put youe finger in it because of the lidenfrose efcet

[wowelite2]

damn, u are rly smart :o say something smart that nobosy wont understand plz :b

[kpesci01]

cool maybe we found another way to store gases.

[rickface13]

that was a smooth move diggin out the liquid nitrogen with the ungloved hand lol

[killerfriend94]

@UserUnknown77 ha yea ive seen that kind of stuff before its acutally pretty neat. um i know you can kind of do it with water. You heat up a flat metal surface to the point were it is the equivalent of nitorgen and our skin right. ITs cool cause like the water glides and floats on the surface.

[Idontcare9876543210]

when it boils isn't it the leyden effect?

[MrMister1227]

What would happen if you get it in your hands???

[TheDrjman1]

Can I be your assistant?

[Kinzlover33]

If you put food coloring in the warm water, would it cause the fog to change colors?

[ScienceBob]

@Kinzlover33 No, when the water is vaporized it does not carry the color with it to any extent that you can see it. I wish it did - that would be cool!

[wussywimpygimpy]

@ScienceBob it would, just imagine it in your mind :D

[MrMariofan13]

which is colder? liquid nitrogen or dry ice?

[ScienceBob]

@MrMariofan13 Liquid nitrogen is quite a bit colder at -320 F and dry ice at -109 F.

[happy103able]

@ScienceBob hey bob, i was wondering if this project can be done with dry ice or does it have to be that liquid nitrogen

[jadiegirl1231]

is dry ice available in the UK?

[chromegenious9000]

the reason it boils i think the term is called the leidonfrost effect

[blanknot]

What would happen if you poured liquid nitrogen into a pool of lava? Would the earth turn inside-out?

[yankeenick]

If you breathed in the fumes(say smelling it) would it be dangerous?

[Kinglion645]

that is AWESOME!

[TakronRust]

Unless you get a lingering amount on yourself, the Leidenfrost effect will protect you from any major injury from liquid nitrogen. But only for a moment, as when your skin cools; the effect will break down and then you will come in full contact with the lN2 and you'll get frost bite.

[yoyo19985]

keep on! love youre videos!

[Hiccupone]

Love the video's bob, keep up the good work :]

[supermar1os]

Scientists don't use the measurement fahrenheit they use celsius!

[andresderasfriend]

@supermar1os yay celsius!!!

[Phrieky]

He's soo awesome! You rock Science Bob!

[PandaMagicFTW]

You don't really need gloves to handle liquid nitrogen, it beads off your hands due to the Leidenfrost effect.

[AhmadAlony123]

I think the balloon shrinked because of his breath.

[snagglejaw]

What kind of gloves do you use science bob? and are you in the NY area? im goign to have a science kinetic art show

[RedFox9911]

you would be the best science teacher ever!!!

[iSoMuchWin]

@RedFox9911 You're forgetting Einstein.

[363jik]

so where can you buy liquid nitrogen?

[snelpiller]

can you keep it in a thermos?

[andomez]

funny how he warns her about wearing gloves when handling liquid nitrogen yet he fully sticks his bare hand into the container with it..

[TheTrollCity]

oh gas laws, how you make chemistry an easy, fun mistress.

[yurim6]

i would want him to be my science teacher any day

[1piecemage]

PV=nRt =p!!

[lillance785]

ahhh you didn;t freeze enough stuff!!!! XD

[DevilMaster]

I read you can use liquid nitrogen to solidify mercury and make a functional hammer out of it... that's something I'd like to see.

[blackshadowy]

where i can get liquid nitrogen??

[TheMonkeyzRule]

@blackshadowy i don't think its legal to have liquid nitrogin, because, it's colder that dry ice, it frezes anything it touches, it is not safe at all

[killerofporn]

will it compress items? i can compres my school and NO SCHOOL

[Second2Rush]

@killerofporn Just blow the Skool up... Its far Easyer,

With this stuff all u can Do is Freeze the Skin (Littarly) Of your Teachers.

[thepapermakery]

@killerofporn hello..you dont rember this comment

[Aslanx10]

@killerofporn

Yes

[2000gmod]

@killerofporn Try it its Funny

[shane44567]

@killerofporn Or compress liquid nitrogen. Then repeat. Then you have pocket size

[halodoody]

What would happen if liquid nitrogen spilled on someone?

[michaelkaliber]

hes clothes will freeze

[halodoody]

i mean like, on a bare hand.

[bestSVMS]

@halodoody

ledienfrost effect. If a litle, a poof and no harm. If a lot then not soo good

[puppystomper324]

ow it would freeze them givve them forstbite

[halodoody]

thats no good, haha

[puppystomper324]

that would be verybad lol

[SiRpAnTsPoIsOn654]

If It Spilled On Some Ones Hand And Den Another Man Was Running Or A Boy And He Hit In The Mans Hand It Will Breake

[killerfriend94]

it would be bad, if left on the skin for more then like a second it would probably cause whatever it touched to freeze. like frost bite. its really cool to mess with but its dangerous.

[zmod101]

@killerfriend94 Check out the Leidenfrost effect it actually allows things like hands to be completely submersed in liquid nitrogen.

[randomkid300]

im lucky. i get dry ice every sunday. and my brother and i played ice hockey with a spoon and somehow dry ice went to his tongue and he screamed a little and i said that doesnt even look like it hurts. when he pulled it out his tongue was bleeding he told me dont do it but later when he wasnt arount i did it and it HURTS!

[eenayeah]

science is the best

[madamefoster23]

i totally agree :)

[bandoleon13]

Where I find the Liquid Nitro ?.. ask to Terminator ??

[me2goodfoyou]

where can buy a dry ice and what is the price per liter or gallon?

[ScienceBob]

We used liquid nitrogen in this experiment. Welding equipment suppliers often carry liquid nitrogen. Typical cost is about $5 a liter, but you usually have to have, or rent a special container.

[utubers10]

wher do u get a pvc pipe from

[realtoyz13]

any big home improvement store

[3d834]

@ScienceBob dry ice is not fancy and its alot cheaper....... so HA!

[dranzerbeyblader]

@ScienceBob where can you find it

[Kevin323gaw]

@me2goodfoyou From guys who sell IcC CreamLOL 

[trevvor94]

where could you get liq.nitro?

[DriftWoodProductions]

liquid nitrogen will do it but dry ice makes thicker (and more) fog/smoke stuff

[llio13]

Potater hahaha

[crazyporcia]

sooooooooooooooooooooooooo amazing cooooooooooooooooooooooooollll­llllllllll awsome u r sooooooooooo cooooooooolllllllll  bob

[sidbud21]

Thats cool..

[billyblackattacks]

am I the only one who thinks this is friggin amazing!
