as soon as the thermite is heated it is classed as a molten metal and when you bring water (ice) into that you get a cold force meeting a extreme heat cuasing a explosion due to rapid changes in the materials its just like a blast furnace they say never to go near one with water for a reason
perhaps the crazy amount of heat is so intence it vaporizes the ice so fast that it's like an explosion, only realy it's just super fast expanding water vapor
He protects all of his body again the possible sudden eruption of fire; but he doesn't protect his hand, which are ACTUALLY going to come in contact with it?
Simple water changing from a solid to a gas at that rate has to expand very fast. The bucket is why it works. It gives the gas a place to be compressed. They should try it without the bucket and just burn the thermite powder right on top.
It's not a mystery at all. What happens in our atmosphere when cold air meets hot air, we thunder. The heat from the thermite met the cold air and not to mention the little bit of gasses that comes from the ice also played a roll...it's called pressure! Hope that helps!
Happens frequently if some poor soul in a foundry decides to use a fire hose to cool off a ladle. Stream of water hits (and penetrates) the molten iron rather than the side of teh ladle.
Looks to me pretty simple. The Thermite boiled water faster than it could escape, pressure builds until there's too much stress for the ice to contain, and it explodes. The force of the first to detonate shocks the other pockets in the other blocks enough they all detonate, seemingly simultaneously.
in my opinion.... they allready said that the fire was approx. 4000 degrees fahrenheit. With that temperature, quite alot ice will melt instantly and cook. creating steam which contains oxygen, enhancing the process which causes the big explosion.
i knew it would explode before they showed it. just because of the way they edited the video together with the guy going i dont think it will explode they but gunpowder in there ect theres no way they would put that in if wouldnt explode
yeah it think it's the mixing of extreme temperatures try for instance to throw a ice cube into boiling water. you will see that before ik melts the ice cracs violently in 2 then it melts.
Mix two extreme tempratures togehter and thats what you get....it was proven well and truely before this ever happened...and yet none of them picked it...makes me think wether or not they have studied reactions.
what if the high temperature of the thermite splits the water in to oxygen and hydrogen and you get double reaction, the hydrogen burns too which that thermite is still rising the temperature and making an explosion instead of fine hydrogen burning.
It would be pretty simple to find out if its steam or thermolisis. Just try it with dry ice. since its CO2 not water it wont create hydrogen or steam. if it still explodes it must be something else
According to wikipedia zincs boiling point is 907 degrees, and thermite burns with 1370 degrees more...
thats 2277 (hehe thats my user numbers, but honestly i didnt know that when i created it :D) degrees, and guys thats CELSIUS:.. in fahrenheit its about 1600 + 2500 thats 4100 fahrenheit aproximately.
Depending on the type of thermite, I'd say the decomposition theory is probable.
Water will undergo thermolysis at around 2200 degrees C and will undergo rapid thermolysis at around 3000 degrees C, which are not unheard of temperatures for thermite reactions.
Looking at the thermal-vision, the ice blocks almost instantly turn the same color as the thermite after the mixture took the flame, and it took a few seconds for the explosion to occur.
However, I'm not doubting the sublimation of water
My thought: the bucket burnt through (as we know is possible from the car experiment). Thermite dripped onto the ice, creating steam that went into the opening in the bucket and forced the thermite out the top, aerosolizing it and causing and explosion, as jamie said.
it may just be my opinion, but isn't there a reason why hot cups are not supposed to be placed on the freezer? because they crack. i think its just the collision of two extreme temperatures making the ice crack @ a much higher ratio. i think it would be even cooler if instead of using a bucket they would just have drilled a hole into a big cube of ice.
I can't believe they don't know what a steam explosion is. There's a reason that factories that work with flammable metals don't have water fire suppression systems.
Now we know how to proceed in a war agains Iceland...
Seriously, i think this explodes because the fast temperature change, causing the fast transformation from ice to steam without come to water and then to steam, just a thought.
what i think happenned in the video, the thermite burned through the bottom, and melted some of the ice into water and went out, and then the untouched and unlit thermite, reacted with the water and exploded as an unstable substance always does
@rocaho001 I think the point is that the fire suit takes a while to burn through - ie, if Jamie does get hit, it gives him time to get away and get the suit off before the burns are serious. It won't prevent him from getting serious burns (I think) but it should help to stop him from dying.
One way to test Jamie's theory would be to take a pile of thermite, ignite it, then hit it with a blast of air or something. I'm surprised they didn't try that as part of the investigation
@thatghillyguy that wouldn't work cuase air is always present so what your technically saying is that they ignite thermite which doesnt further the cause of science. air is composed of oxygen, nitrogen and other trace gases so that experiment of yours would be redundant.
@lotharsredemption Dude, you trollin? Anything that burns or explodes is significantly more volatile when it's effective surface area is increased. It's why you dont pour water on burning cooking oil and possibly the reason why thermite and ice causes an explosion.
@lotharsredemption Also, the experiment is NOT pointless because even if it doesn't yield hypothesized results, it will at least disprove some things. Thus, SCIENTIFIC METHOD YOU NOOB
@j4wb0n3 at one atmosphere, the sublimation of water is not possible. That's just judging by the phase diagram of water. If anything, it is just rapidly transitioning from solid to liquid to gas.
wouldn't the "matches" cause the boom? like they do put two matchbooks in the thermite, and set that off. plus then they added four and their boom did look bigger. im just saying.
@pman0391 mtaches by itself can only cause i fireball and thats wen you have over 30000 of them (mythbusters proved it) so the only culprits are the ice and the thermite
Very nicely done boys! I am so grateful that you have the time to do so many things which I also would like to do. But I don't have a handy bomb range and Frank Doyle. I am liking that you can do it for us. Thanks one and all!
(Fe2O3+2Al -->2Fe+Al2O3+heat) if you're using ordinary "red" iron oxide (ferric oxide possibly the H2O decomposes so fast with the heat the O is liberated and you get a H gas explosion ?
I would say it may be as simple as suddenly heated (super-heated) water producing lots of steam. This steam blows molten thermite all over the place. Whatever happened it is two thumbs up!
@wb5rue I'd absolutely agree. Steam explosions from molten metal touching a damp sand mold are one of the oldest industrial hazards. A fairly small steam explosion could then blast the thermite powder and molten metal upwards in a highly combustible cloud, prompting its own blast and creating a fireball.
Hydrogen is produced when steam is exposed to red hot iron and brass will also explode if water hits the molten metal and the oxygen in the water also burns the metal adding heat to the explosion as anyone who casts metal will tell you.
the bucket is over the ice, the thermite is burning a hole through the bucket and making a hole in the ice, the ice is melting very fast and the termite is burning causing the hydrogen and oxygen around the ice escaping fast to explode.
@SecondAgeOfReason ya we do, its called a sparkler, like a birthday sparkler, i thermite weld the railway,the way they do it thats a weird way 2 do it, just add a sparkler and walk away lol>>>they have lots a money and research y didnt they ask thermite welders on the railway to do it safely lol, cool video though!!
A part of the bucket melted and touched the ice. Temperature changed too rapidly and resulted in a blast.
You'd get a similar effect by throwing a bottle of water into a ton of molten steel. Blasts like that have killed many workers, and even today working with molten steel is considered dangerous.
@SinfireTitan That theory juts doesn't have a leg to stand on. Temperature change does not cause explosion in LIQUID material, only glass and metal. That was CLEARLY not just the vaporizing of the water, there was a very loud bang. If it was vaporizing you would hear a big hiss. Working with molten steel is considered dangerous, even today?? Are you sure about that? I had no idea!!
@Stillwater900 Actually steam explosions can be very loud. A quantity of water instantly vaporizing does make a bang, or can. I've heard it, kind of scary too!
@Stillwater900 By your reasoning, a water heater or boiler could never explode because the material is liquid. Nor could a rocket explode, because it uses liquid fuel.
@ELuhn Those examples you gave a flawed, boilers explode because of the pressue of water vaopr, rockets don't explode, but they are fueld by directed escaping gas FROM the oxidized fuel
What we see in the video is an expansive explosion, whatever happens is happening very quickly. Putting a piece of hot metal on ice will never cause it to explode
I might be a bit chemically naive, but could the reaction be similar to that of a grease fire explosion when water is added.. since water expands into gas at a rate of like 700%, is it a possible scenario with the thermite?
Well what about the actual thermite reaction? Aluminium is the more reactive compound in thermite, so it "pinches" or takes oxygen molecules from the iron, and if you know anything about metal fires, if you add water to hot iron you produce hydrogen gas, thus creating an explosion, perhaps?
It is caused by hydrogen being produced out of the water when the burning thermite hits it. I had to do some digging and found a chemist posted on discovery channel > mythbusters forums. The explanation is long but has to do with "molten aluminum with iron oxide particles" ripping the oxygen out of the water and leaving behind hydrogen. The fire ignites that and... BOOM!
From my point of view the actual thing that happens its rather simpler...i mean take some ice cubes and slowly pur room temperature water over them the ice will brake or even pop out of the glass...so imagine this phenomenon in the proportions showed in the clip....eitherway its awsome!!!
@gratsounas I think this as well. It's called thermal shock. It's the same reason you're not supposed to rinse ceramic bowls immediately after taking them off of a bunsen burner. The low thermal conductivity, low toughness, and high thermal expansion coefficient all encourage an explosive fracture from rapid heat changes, whether by cooling or heating.
The ice is melting and the water is breaking down into hydrogen and oxygen. Certain rocket fuels also burn hot enough that water cannot be used to put out a fire.
i think this might be related to the occurance of when a glass candleholder which has a lit flame inside heats the glass and when it suddenly gets hit by cold it warps quickly and breaks. can't know for sure glass and ice aren't the same
@DiabloY123 Yep your right ,even if you heat a pice of metal too 1000 F and drop it into a glass of 34 F water it will explode I seen it happen before its the same thing block of ice meets 4000 F Bucket of burning Thermite BOOM !
it's flash vaporizing the ice below the bucket as soon as the bottom of the buckets gone then the steam jets remaining termite into the air increasing its surface area and causing an explosion
Could someone explain the pressure blowing up the experiment? I fail to see how pressure can be built when it is not contained in a small area. (like a chamber)
Ok, well I haven't watched the end of this so I don't know what their final conclusion is, but if you have damp rust, it explodes due to the vapourisation of the water.
This reaction has enough energy to melt iron, so it easily has enough to vapourise ice... It'll be steam pressure.
Also I'm pretty certain no matter what temperature and pressure you got to, hydrogen bonds to oxygen will be stronger than iron, this reaction wont react with the water (in a chemical sense).
Couldn't the ice stall the ignition of the thermite allowing the reactants to build up until their volume and temperature finally beat out the cold of the ice and all ignite at once? Kind of like the plutonium tamper in a thermonuclear bomb. It only holds for a few nanoseconds, but that's more than enough time to multiply the yield by a factor of millions.
When u mix oxigen gas and hydrogen gas u get so called "thunder-gas" (O2+H2) , even small amount of that gas has very big explosion power. So i think when thermite react with ice it free some oxigen and hydrigen gases , they imediatly blow up because hight temperature
Isn't it possible that the explosion is due to rapid expansion of gas trapped in the ice (the blocks of ice were opaque)? The gas would be expanding from 0 to a few thousand degrees C. Calculating from PV = nRT, the volume would expand over 10 times in a relatively short amount of time. Rapid formation of steam might also contribute to explosion this way.
@emmessjee That is what he said in the video. He did not like that idea as it would require all (or at least a lot) of the ice to turn to gas at the same time.
@emmessjee PV = nRT is for Perfect Gases only... I Don't know about the rest of your explanation, but if your theory is based on this formula, it is wrong.
@WildyWarrior@emmessjee You're right WildyWarrior, but you can apply the Real Gas law in place of the Ideal one. It is virtually the same equation, but with constants "a" and "b" incorporated.
There is a possibility that the heat of the thermite reaction caused the water to become very acidic based off Van 't Hoff's equation, dissociating into very reactive H+ ions. Those could have caused the explosion
another look at it shows some explosive cloud of orange flame... could be hydrogen... they could test this again with water at the btm. should give a similar explosion if it's due to water.
couldn't it have exploded because the ice in the middle became so hat that it nearly instantly became steam which had enough pressure to blow the (not yet melted) ice blocks away.
On December 24,2006 at 8 o’clock in the morning, a young 14 year old boy by the name of Scott Jackson was found dead.Doctors couldn’t come up with the cause of his death.His mother checked his emails to see if she could figure out what happened.Turns out he was still signed into myspace.She found he had gone to sleep after he read and didn’t repost a chain letter.if you don’t repost this to 6 videos a girl with no face will kill you tonight. sorry don’t wanna die
This comment has received too many negative votesshow
this is a lame lame demonstration. these guys are just laughable tv turds. lets do what a couple of kids just did. and also they purposely mislead you about thermite due to some event that happened a while ago that mainly depended on thermite charges but we dont talk about it because of its delicate political implications. go to hell tv. you suck mythbusters
@DINGLEtheBERRY So will you care to show the rest of a world an even better demonstration? Of course you won't. You have no room to criticize if you aren't willing to one-up a demonstration.
@Dungeon287 there are a pile of better ones if you care to look. im not holding your hand. the kids they showed at the beginning of the show blew these two adults out of the park. sorry i call them as i see them.
@DINGLEtheBERRY How did they "blow them out of the park"? The explosion that the MB's did was much larger. Do you have to make up stupid little things in order to prove a point?
@Dungeon287 its the exact same experiment and those kids are about 14 and these dorks are middle aged. i am reluctant to call such a couple of duefuses adults. kids blowing up shit in their backyard is exciting not a couple of pinheads running away and hiding behind some plexi. dude society has been dumbed down sufficiantly so maybe we could level off a bit at least. it will take a little thought though.
@DINGLEtheBERRY It's the same experiment on a larger scale. Would you not want to be behind some protection if you're experimenting with shit that could kill you?
@DINGLEtheBERRY So you compare the two experiments, calling them the same. The one that the teenagers did was apparently more exciting. If you think it's the same experiment, how is it boring? Unless you're calling the video that the MB's based this off of was boring as well, which would contradict you saying "kids blowing up shit in their backyard is exciting". The choice is yours.

You'd get a similar effect by throwing a bottle of water into a ton of molten steel. Blasts like that have killed many workers, and even today working with molten steel is considered dangerous.

@SinfireTitan That theory juts doesn't have a leg to stand on. Temperature change does not cause explosion in LIQUID material, only glass and metal. That was CLEARLY not just the vaporizing of the water, there was a very loud bang. If it was vaporizing you would hear a big hiss. Working with molten steel is considered dangerous, even today?? Are you sure about that? I had no idea!!

@Stillwater900 Actually steam explosions can be very loud. A quantity of water instantly vaporizing does make a bang, or can. I've heard it, kind of scary too!
zeppelin67637 3 months ago
@Stillwater900 By your reasoning, a water heater or boiler could never explode because the material is liquid. Nor could a rocket explode, because it uses liquid fuel.
ELuhn 2 months ago
@ELuhn Those examples you gave a flawed, boilers explode because of the pressue of water vaopr, rockets don't explode, but they are fueld by directed escaping gas FROM the oxidized fuel
What we see in the video is an expansive explosion, whatever happens is happening very quickly. Putting a piece of hot metal on ice will never cause it to explode

I might be a bit chemically naive, but could the reaction be similar to that of a grease fire explosion when water is added.. since water expands into gas at a rate of like 700%, is it a possible scenario with the thermite?

Well what about the actual thermite reaction? Aluminium is the more reactive compound in thermite, so it "pinches" or takes oxygen molecules from the iron, and if you know anything about metal fires, if you add water to hot iron you produce hydrogen gas, thus creating an explosion, perhaps?

It is caused by hydrogen being produced out of the water when the burning thermite hits it. I had to do some digging and found a chemist posted on discovery channel > mythbusters forums. The explanation is long but has to do with "molten aluminum with iron oxide particles" ripping the oxygen out of the water and leaving behind hydrogen. The fire ignites that and... BOOM!

From my point of view the actual thing that happens its rather simpler...i mean take some ice cubes and slowly pur room temperature water over them the ice will brake or even pop out of the glass...so imagine this phenomenon in the proportions showed in the clip....eitherway its awsome!!!
gratsounas 4 months ago
@gratsounas I think this as well. It's called thermal shock. It's the same reason you're not supposed to rinse ceramic bowls immediately after taking them off of a bunsen burner. The low thermal conductivity, low toughness, and high thermal expansion coefficient all encourage an explosive fracture from rapid heat changes, whether by cooling or heating.
Intrafacial86 4 months ago
The ice is melting and the water is breaking down into hydrogen and oxygen. Certain rocket fuels also burn hot enough that water cannot be used to put out a fire.
TK42138 4 months ago
i think this might be related to the occurance of when a glass candleholder which has a lit flame inside heats the glass and when it suddenly gets hit by cold it warps quickly and breaks. can't know for sure glass and ice aren't the same

ultislasher1 5 months ago
Ok, well I haven't watched the end of this so I don't know what their final conclusion is, but if you have damp rust, it explodes due to the vapourisation of the water.
This reaction has enough energy to melt iron, so it easily has enough to vapourise ice... It'll be steam pressure.
Also I'm pretty certain no matter what temperature and pressure you got to, hydrogen bonds to oxygen will be stronger than iron, this reaction wont react with the water (in a chemical sense).

Couldn't the ice stall the ignition of the thermite allowing the reactants to build up until their volume and temperature finally beat out the cold of the ice and all ignite at once? Kind of like the plutonium tamper in a thermonuclear bomb. It only holds for a few nanoseconds, but that's more than enough time to multiply the yield by a factor of millions.
MultiPaulinator 5 months ago
When u mix oxigen gas and hydrogen gas u get so called "thunder-gas" (O2+H2) , even small amount of that gas has very big explosion power. So i think when thermite react with ice it free some oxigen and hydrigen gases , they imediatly blow up because hight temperature

Rockinlocky99 5 months ago
Isn't it possible that the explosion is due to rapid expansion of gas trapped in the ice (the blocks of ice were opaque)? The gas would be expanding from 0 to a few thousand degrees C. Calculating from PV = nRT, the volume would expand over 10 times in a relatively short amount of time. Rapid formation of steam might also contribute to explosion this way.

@emmessjee PV = nRT is for Perfect Gases only... I Don't know about the rest of your explanation, but if your theory is based on this formula, it is wrong.
WildyWarrior 4 months ago
@WildyWarrior @emmessjee You're right WildyWarrior, but you can apply the Real Gas law in place of the Ideal one. It is virtually the same equation, but with constants "a" and "b" incorporated.
There is a possibility that the heat of the thermite reaction caused the water to become very acidic based off Van 't Hoff's equation, dissociating into very reactive H+ ions. Those could have caused the explosion

@Dungeon287 its the exact same experiment and those kids are about 14 and these dorks are middle aged. i am reluctant to call such a couple of duefuses adults. kids blowing up shit in their backyard is exciting not a couple of pinheads running away and hiding behind some plexi. dude society has been dumbed down sufficiantly so maybe we could level off a bit at least. it will take a little thought though.

Unless you're calling the video that the MB's based this off of was boring as well, which would contradict you saying "kids blowing up shit in their backyard is exciting". The choice is yours.
