Mythbusters - Thermite Vs. Ice

[TheCrazyNuggetFR]

About the explosion, I think that the thermite consumes the oxygen contained in the water (water's chemical formula is H2O), leaving hydrogen alone. And since hydrogen is a highly unstable gas, due to the heat emitted by the thermite, it goes BOOM =)

[Brunomaar]

I think its funny that the first thing Jaime does after it explodes is check to make sure his hat is still on! hahahahahaha

[NITRORCXCAR]

are you norwegian? (er du norsk?)

[anshulkamboj]

these internet viral videos are mostly fake ,

[MrShockFish]

If your a retired FBI agent and are running out of money, why not go on MythBusters?

What's so surprising? The lava-ish bucket content flows over the ice (best visible in infrared), causing the ice (=water) to vaporize and because it's covered in molten thermite the steam cannot expand.. boom! More or less the same what happens on/in volcano islands

[ReaperKing158]

Fire and Ice = BoomBoom(Condom)

[gnagarn87]

its exaclty the same as when you have molten steel, around 1600°c or 2900ºF, and get water into it... for example, a little piece of ice comes in contact with the steel, it instantly melt and expand 1000 times!

and there´s your explosion.. 1kg of ice becomes 1 square meter (10 square feet) of steam INSTANTLY = BOOM

[BarneySaysHi]

Jamie jumped higher than Adam!

[fundilyfun]

it might be the ice attempting to expand to quickly

[PaintKyZR]

Cool guys don't look at explosions.

[TenTonHorse]

2:18 ADJUST CAP!!

[clerlic]

They should try putting a bottle of water in a bucket of thermite, the water will superheat and explode in the same way.

[javamochacocoa]

Ice cracks when warmed quickly. So I am thinking that with how much heat hit the ice it shattered so quickly it exploded the thermite everywhere!

[ernie750]

let's see... molten iron at 5,000*F and water. Steam explosion, anyone? Chernobyl ring a bell?

[Mondotoast]

0:50 >:C



[erlandjnilsson]

naah you can see that it is a block of ice that explodes from vaporizing

[thespartanmk1]

Could it be that the Ice is turning into water and flash boiling? Doesn't Thermite burn at 4000 degrees?

[killer8520178]

9/11 :D

[solarsystemkid]

Boom

[DyingElement]

Oxygen and hydrogen??? What kind of "expert" is that? You'd need a nuclear reactor to decompose water into oxygen and hydrogen...

[elucidation]

@DyingElement or a 9v battery...

[ismasalgado]

@DyingElement actually, you dont. Thermite get over 1200° celsius only being there...

[lyth1um]

@DyingElement its possible to make oxygen and hydrogen, out of water just with the sun ;) and 8 levels of mirros, sunoven

[lyth1um]

@DyingElement and it just needs 3000°c to make it

[AugustinusSextus]

@DyingElement dude, en wikipedia org/wiki/Electrolysis_of_water­

[moabfool]

Steam explosion.

[funguyround]

wow. notrojan fire and ice ending in a "boom" comments

[Diamas1985]

I would like to see Thermite vs Liquid Nitrogen!!!!!!! xD

[crosspatch]

Looks like a typical phreatic explosion to me. The high temperature thermite so quickly vaporizes the ice that it just explodes. Same happens in volcanoes when magma comes into contact with ground water or surface ice. Pretty typical in places like Iceland as magma rises. Thermite is as hot as molten magma. Might not be the same as magnesium and water because there is no chemical reaction with iron as there would be with magnesium. I believe it is simply a phreatic explosion.

[Georder]

Maybe the Ice just sublimates instantly like you blow water in burning oil, so that the expanding water rises of the burning thermite. This was my first idea ...

[ShneekeyTheLost]

It could simply be from a rapid temperature change in the bucket itself. Metal conducts thermal energy readily, therefore, it can be assumed that the temperature of the metal in the bucket was near that of ice. When the temperature of the bucket was suddenly increased to the temperature of the Thermite reaction, it suddenly expands, and probably also melts. This is why no bucket was found... it was splattered as bits of liquid metal rapidly expanding outward.

[bendhoward]

It's a mystery?! Way to throw the science out the window...

[stefannikolovski1234]

try the dry ice and you will fail - dry ice can defeat thermite!

[maxasken]

hates the FBI guy

[gooeyking]

this video is just a cover for what happens when you attempt to divide by zero

[MegaBushMonster]

I realy want to do this experiment right now I have a video of a planting pot full of thermite eventualy im going to put thermite and ice on my channel

[bakeddobes]

the ice decomposed into hydrogen and oxygen to generate the explosion

[crispycritterz]

Chem 101...



[booyahoo00]

It burns so hot it creates a molacular separation of the hydrogen and oxygen that water is composed of. Take and light magnesium on fire and pour water on it, similar reaction

[acronus]

Fe2O3 + 2Al → 2Fe + Al2O3.

H2O decomposes at 2500°C.

Thermite generates heat in the 2500°C to 2800°C range.

Aluminium has a high affinity for Oxygen.

Could enough H2O even have decomposed to generate the explosion?

I would assume that if the thermite was being aerosolized, the result would look more like the Mythbusters sawdust cannon.

[dizekat]

they just nearly busted the myth of working thermite the first time

[plrokster309]

Steam is aresolizing the thermite, or we have the decomposition of

2 H20 --> 2 H2 + O2, and the hydrogen gas produced causes an explosion. Be it that thermite burns at over twice the temparture required to decompose water, it is possible.

[laurensreinds]

I think the've done something a little iffy. :c

[rotomthunder]

i still say it is a tempreature clash

[Emu1gmx]

well im pretty sure its the stuff with hydrogen... same thing only larger happend in chernobyl 1986?

[Tjita1]

My theory is as follows: Thermite veryveryvery hot. Water boils att 100°C. So what happens is instant boiling of the water. Try for example (or rather, look it up here on YT) to put out burning oil with water. Thermite is way hotter than burning oil.

[b1912313]

@Tjita1 Well, the explosion does not occour if set over liquid water. That would invalidate your argue I think.

[vanad1umbro]

I'm deffenetely gonna try this one day

[WelcomeToMyDream]

like the other comments.. its fucking steam!!

[LucaTurilli89]

Why they cannot use high framerate camera to see what happens just before the explosion?

[Kazzeroth]

@LucaTurilli89 It's very hard to see atoms and small particles. :/

[LucaTurilli89]

@Kazzeroth but the two possible theories should have different effects yes/no? Can't they use telescope and small amount of chemicals?

[Kazzeroth]

@LucaTurilli89 Oh, true.

[dandypajamas]

Anyone else hear the narrator say "retard FBI man" at 0:37?

[EvilStar109]

@dandypajamas He said "retired".

[illumined1]

given the high temperature of thermite and tremendous pressure of water vapor, I would say it is steam generated by the heat quickly enough to create enough pressure to blast it apart.

[punxsutawneybarney]

The mythbusters guys set off 1000 pounds of thermite to try to cut a car in half. See how it turned out in my video:

Incendiary Experiments

[OmegaArbinator]

The ice just instantaneously vaporised into a gas when it was exposed to the heat from the thermite, there was no hydrogen or oxygen decomposition or anything. I am surprised at you, Jamie.

[rechitsapivo]

OMG what a f.ng mystery!

You do not require explosives or hydrogen to make an explosion. Any explosion is just rapidly expanding gas. How fast do you think water vapor will expand when water is rapidly subjected to 3000C? This is nothing but a steam explosion.

[whatuwantmom]

wow the video i saw on their computer was the one i just watched befor i came here

[tomatoes725]

does anybody know why the retarded fbi agent was sad ?

[TheBuxxx]

Is it just me or does it sound more like "Retard FBI man Frank Doyle"

[dradasz]

No. It's quite simples, water thermolysis.

[slack3r9]

this is basic science. its the extreme change it temperatures that cause the explosion. even i knew that before seeing this

[elementsktr1]

its from the ice cuz if u listen when u drop ice into a cup of room temp water it cracks and thats probably whats happening here but explosionier

[silverzephersword]

something that would make this video way funnyer is if the one guy who found the ice by the blast shield, broke the thing when he threw the ice at it

"Luckily it's ice proof! (CRACK)...oops..."

[Patbad73]

@silverzephersword You don't even know his name....

[tubemaster2703]

Well, there's your problem.

[weirdone17]

0:38 i thought he said retard. but he said retired

[CrisisCorEzz]

@weirdone17 he certainly looks retard :D

[gargravarr2]

Or as a simple explanation, the thermite burns its way to the center of the ice stack, turning the insides into steam which creates a huge pressure.

[dxxa94]

this could be explained with; sudden separation of molecules of water at and incredible speed

[WunderDoob]

Thermite burns hot enough to cut structural steel like butter. That's what brought down the World Trade Center buildings. They (firefighters and search volunteers) found molten steel at the base of the rubble several days after the "terrorist attack"

[JJincorp]

If you drop an ice cude into really hot water or tea or something, the ice cube will also explode, packs a pretty mean punch also compared to what you would think

[thugrip]

faen, skrev masse loke greier, men så forsvant det... mata bilde og video, for ikkje å snakke om tilbakestående opplegg og eksplosjon. 5 triangler på denne videoen.
