  • well im going to be more carefull know i never knew that could happen

  • O.O i just poured molten aluminum on bare foot, gardening gloves and no face protection at all, I'd be dead or horribly deformed it that had happened to me D:, i guess Il ought to start wearing protection, what an asshole I am.

  • this is today's kids DUMB AS obama

  • weirdest fail ive ever seen :D

  • They didn't preheat the mold to near blue hot. Doing this ensures that there is no moisture in the mold (could cause a rapid steam expansion resulting most likely in what we see here) and makes sure the metal being cast cools evenly and slowly.

  • haha.take that MOTHAFUCKA!!!jk, great vid.

  • this is most likly because of a cold mold, or some water in the mold

  • That has happened to me whilst soldering.. It was a bad day.

  • It makes me sad that it didn't splash onto your face. Stupid people need consequences, or they'll never learn their lesson.

  • @Supermassively It would make me sad if you're an adult saying that. People fuck up. This is a very dangerous fuck up and could have easily been avoided, but they do not deserve any more than this. You sad, sad human being.

  • @XxENovaxX And that kind of bubble-wrap mentality is what has raised a generation of morons with no personal responsibility or regard for consequences. People should have to endure the consequences of their stupidity, or they'll never learn to be less stupid.

  • That's bad.....really, really bad.

  • Why the FUCK would you poor it on a cold ingot? That's common sense man. Hot... cold?

  • lol says that he wasn't wearing a face shield and then told the intructor that he was lol!

  • pre - heat that shit ! moisture in your ingot pigs...

  • dude i saved your hand, lol

  • that was so fucin dangerous you should feel lucky

  • don't pour that fast...its called a cold shut cause by the metal hit the back end of the mold and crashing back over on top the hotter metal

  • Take your time to understand what can go wrong. Hope on one was hurt and we can all learn for this. It is easy to see what is wrong after the fact like texting and driving can be. Look out safety upfront as much as possable. I like the post it will remind me to be more careful in my work.

    Thanks

  • Pour the hot metal right onto your testicles next time

  • Comment removed

  • "you had your shield on?"

    "Yeah yeah"

  • COLD MOLD - HOT METAL - dampness and humidity in the surface of the mold...

    DUMB FUCKS.

    ALWAYS HEAT YOUR MOLD to above 100*C - because you never know how much "dampness" is in it, who has spilled things over / into / washed it ??????

  • I don't understand all the bashers here. This is a good reminder for people dealing with molten aluminum, so thank you for sharing.

  • LOL FAIL 

  • Aluminium > Aluminum

  • @ojideagu You say Potahto, I say Potayto.

  • i want to know why the one opening it has the face shield and the one holding it doesnt LMFAO..

  • maybe you should be a photographer..............

  • he's lucky that didn't splash in his face.. that would suck ass

  • hey can anyone tell me what is the name of that smelter/furnace they used or maybe a link to a website pls, it would help out alot thx

  • Your lab privileges are revoked - even WITH adult supervision.

  • That's 100% f*cked up.

  • @Mrgyn

    Yes I was, it was awesome lol

  • molten aluminium behave like very strong acid... I saw scars of old an aluminium smelter... horrible look... so always wear proper safety wearings...

  • I was taking out the trash when this happened... and I come back and I see smoke coming out of the building. Memories.

  • @Chrisisswell

    Haha you were here?

  • Morons. And you even blow on it? Hahaha.

  • Good thing that they don't use water to extinguish it...

  • Oh god there are just so many problems with this it's hard to begin thinking of what should have been done better.

  • Darwin awards, not wearing a face shield. Then when they are putting the fire out they don't even have safety glasses. Then the teacher comes in and he's not wearing any safety glasses either. The work area is not right either, way too cluttered with junk. You should have an open area around the mold with nothing combustible, and a steel grate work table.

  • When pouring metal the mold needs to be heated to a degree to avoid this sort of thing. Same reaction happens when you boil water in the microwave for about 5 mins and put a cold spoon into it.

  • why isn't the guy pouring the metal wearing the face shield?

  • These guys were sooo close to feeling some real PAIN

  • there's a red hot crucible sitting on the counter and their worried about a little bit of fire...

    also, good to see they have goggles on, but what happens if it splatters onto the rest of their faces?

  • The crazy part about this is that he now knows how to play the banjo and rides a unicycle!!!

  • lol, this video should get tons more views, its interesting and awesome at the same time. <3 science

  • So why did this happen, did your mould have to be hotter?

  • @80glasstiger

    When the aluminum was poured into a cold mold, it transferred its heat, and solidified slightly. It cooled and contracted, but also had a slight foothold on the rough surface of the mold too. The popping was the ingot losing its adhesion, snapping back into its contracted shape.. and expelling the still molten metal poured on top. Never preheated my ingot molds before, and never had this problem... but the alumi looked much hotter than standard pouring temps.

  • Comment removed

  • It's time for another Good Idea-Bad idea:

    Good Idea: Don't be an asshole.

    Bad Idea: Be one.

    The End

  • dumbass!!!!!!!!

  • Maybe a drop of water? Similar to when I did a lead pour without properly drying the mold... same thing happened.

  • Air-bubble? Contamination in mould?

  • cold billet +molten alu+little knowledge = fuck up

  • What the hell is Aluminum?

  • @splid1 It's what Sir Humphrey Davy (an Englishman) called it originally. Like any good colony, we went along. Leave it to the English to cock the whole thing up.

  • No idea. If i had to guess, the metal that they were pouring into was cold.

    the aluminum cooled so fast that, after pressure built up, stress in the molt, as it was hardening, ejected.

    no idea.

  • god damnit ..... i already paid that hitman

  • -.-..........

  • probably grease or water or some some in the stupid mold

  • Incredible that no one was seriously burned here.

  • i know this is serious but that "WTF!?" at the beginning of the video was hilarious

  • that guy was so lucky

  • Was the mold wet or something?

  • Protip:

    NEVER PUT ANYTHING REALLY HOT ON SOMETHING REALLY COLD!

    Also:

    Aluminium and rust = thermite.

  • Wow, that was awesome!

  • Keep bloowing keep blowing what the fuck just happened

  • Stop practicing whatever you are studying until you realize that necessary safety precautions are there for a reason.

  • woah good thing those scrubs had cat like reflexes... 

  • @GetReal38 whyd you call them scrubs you fuckin piece of shit

  • @RebirthWoWGuild for obvious reasons troll. why is there always a dumbass who feels the need to comment negitivly upon another's comment? get a life dick.

  • why didn't the guy pouring it have the face shield instead of just the goggles?

  • There's a liquid in the mold that their pouring the aluminium into. It makes contact with the aluminium at 0:15

  • I'm glad none of you were hurt. I'm not gonna lie, I know ZIP about metal pouring or whatever and proper procedure, but even I can see what you guys did was neither safe nor proper. :/ Do they even let you near that thing anymore?

  • They're lucky the crucible didn't explode when they hit it with the CO2.

  • I meant the pouring cup.

  • I like how there acting Spanish at the beginning then they break the thing and there all like WHAT THE F*** WHAT THE FUCK ITS BURRNIIINGGG!!!

  • A simple blow-dryer could have prevented that. make THE FUCK sure that no water is present in your mould Yeeezz..

  • That's bloody terrifying

  • fucks sake i know nothing about pouring metal and i could instantly tell what happened. have these retards never put cold water into a pan with hot oil? wtf?

  • As stated a few times in the comments.

    The mold or pot needs to be preheated.

  • they should have heated up the ingot mold with a torch and they would have been all set. cold molds and molten anything dont mix. I know!

  • This is one of the only videos that I've seen on youtube that made me legitimately nervous

  • Should have read 300" (inch) billets and T-ingots.

  • I work in an Aluminum smelter. Water expands 1,700 times when it flashes to steam. If you pour metal OVER water, this is what you get. We pour metal INTO water all the time for 300' billets and T-ingots. And, the fire was caused by the red hot crucible contacting the combustible table. The only way your going to extinguish that fire is to remove the heat source. CO2 seemed to be a lucky response, cooling the crucible. All in all these 2 goobertards were lucky. BTW, metal bounces off the skin.

  • @macnorman When the hot melted meltal bounces off the skin?

    abd doesnt it cause any skin injurie cause of it's intense heat?

    btw this aint a sacastic question, im just curious lol

  • @H3nryTheChief Nobody can understand your broken English.

  • @Supermassively I should have paid more attention in class then.

  • @H3nryTheChief Depending on how much moisture is on your skin and how molten the metal is.

  • @epohnopulse i see, thnx for that

  • @macnorman and*

  • Comment removed

  • amateurs !!! they are just lucky nothing bad happened

  • What was it? A reaction to the change in temperature of the container?

  • omg you gotta use NaCl to put the fire out

  • @shakedown33 That's salt. Salt won't put that shit out, retard.

  • @jmerridew124 I know it's salt, regular table salt in fact. Yes you are totally right, it wont extinguish the flames. I thought it said burning magnesium, which you can you put out with for example NaCl. My bad

  • @shakedown33 Haha no worries. Sorry for calling you retard. It's my favorite form of emphasis.

  • That is soo crazy... it just popped dude.

  • At the left land side of the mold, you can see both a shiny spot, like a nugget, and a dark spot, like a stain. As soon as the molten metal hits this area, the reaction occurs.

  • Hilarious! Oh my, I'm amazed something bad didn't happen! And you tried to put it out using a glove! I say cut it off from oxygen if it's a normal fire, or just, get a fire extinguisher, and make sure you don't take forever.

    You guys were lucky! Though, I don't like it when people get lucky, and I don't think death does either.

  • Dip shits... all of them.

  • Wow ummm...Mr. C is kind of a shitty teacher.

  • were they investigating Murphy's Law?

  • @RadicalMassacre - I think they were trying for a Darwin Award.

  • @Nudgie68 Agreed!

  • @RadicalMassacre Likely. But then again, because of murphy's law, any experiment, can turn instantly on accident, into a test of Murphy's law.

  • why was he speaking a different language in the beginning?

  • dude i saved your hand...........

  • Notice how it scared him so much, he started talking English?

  • Holy crap that was close ! This looks like a college laboratory. Based on my own experiences it is apparent that most college laboratories have pretty lax standards compared to industry. At my work health & safety and proper procedures, training and certification are always emphasised. College laboratories are inherently dangerous in my opinion due to poor design, overcrowding, students hurrying to finish their work on time, and general lack of safety training.

  • @juandenz2008 Its Bosco Tech, a private high school.

  • The problem that started it all was, that the experimenters were not properly instructed before conducting the experiment. It only went downhill from there: working in a completely cluttered lab on a cluttered table next to inflamable equipment, metal much too hot (must've attracted hydrogen like hell), ingot not preheated, no good place to set down the crucible, not prepared to handle the fire. Also the protection should've been better although i've seen it carried out with similar protection.

  • Dude that scared me when it popped

  • "dude I saved your hand" LOL

  • Ppe is for pussies

  • @dwill6060 and no PPE is for dead idiots

  • Does any body else wonder why the white guy has the face shield, and the guy who is doing the actual pouring only has the goggles?

  • Thats nothing, go push in 3 900 lb ingots that weren't preheated into a 1500 degree 100000lb furnace Now that'll get your attention!...and destroy the bricks and expand the metal and pour all of the metal into the pouring pit and set everything within a 75 ft radius on fire. Or just for fun, throw a just finished soda can into the furnace...I miss my job

  • derp

  • I swear I almost smelled burned human flesh.. fucking luck, dudes.

  • This video sucked, fuckin guy didnt get any on his face. Don't watch

  • My guess is that the water condensed underneath the aluminium, instantly boiled and shot up as one bubble.

  • Dude, I saved your hand.

  • you can always tell when judgmental redditors comment on youtube videos.

  • what the fuck DID just happen?

  • Not sure why the students are being criticized so much. As far as I can tell, their reasonable safety precautions actually DID WHAT THEY WERE SUPPOSED TO, in that no one wound up screaming with a severe burn...

    Molten metals are inherently dangerous. Maybe they could/should have preheated the mold but there is always the possibility of some unexpected behavior, and it appears they were reasonably prepared for it.

  • @paulrpotts

    Not prepared.  At all. It burned through their shit.

  • @paulrpotts That was just a fluke though; they should have had full-face shields for this; if the molten aluminium had hit their face, it would have stuck and they would have been terribly burned.

  • @wolfekeeper that is a fair comment -- watching it again it does seem to me like they both should have had the full face shields -- or at least the guy who was the one close to the metal doing the actual pouring.

    I have not worked with aluminum, but I've worked with students and molten bismuth using gloves and goggles (in smaller quantities than that). There is a big difference in melting point though (520 F v 1220 F) and a small spatter of bismuth would not burn you right to the bone...

  • @paulrpotts IRC molten aluminium is more or less reckoned to be the most dangerous of the molten metals to work with.

    Bismuth isn't the same thing at all.

    Also, molten aluminium is highly reactive, and mixing it with any significant amount of water often leads to death-by-fireball.

  • @paulrpotts You don't know why this is being criticized? Oh god. You're probably one of those people who think it's cute to let their 5 year old drive so as long as they wear a seat belt.

  • @paulrpotts they werent prepared for it at all. i guess you could this improvision

  • Not aluminum, wouldn't be red in appearance. Aluminum resembles liquid mercury when in a liquid state,

  • @gazzaCAN1 MOLTEN aluminum.

  • @iansull Molten aka liquid state

  • @gazzaCAN1 right. molten aluminum is not silvery in color. just like pretty much any other substance on the planet, when heated that much it will be a red to white color. i don't think you're going to get aluminum to look silvery when molten unless you put it under so much pressure you can lower its melting point significantly.

  • wow you guys are idiots. 

  • "You had a face shield on?"

    "Yep."

    Liar.

  • You guys got so lucky.

  • CLOSE THE FUCKING OVEN DOOR YOU RETARDS

  • Always preheat the ingot molds and wear face shields.

    And to the rest of you people who have no knowledge of what happened and can't say anything but "Ur idiots and whoever authorized you is stupid" , shut up. True they should've had the molds heated but, being able to detect the trace amounts of moisture in the mold is nearly impossible, you just have to take preventative measures.

  • @billygotgrove

    They were attempting this in a chemistry lab, on a desk, littered with junk. They were in a wrong place doing their little "experiment" in the first place. Just because you can use a kiln as a furnace doesn't mean you should, just as having knives, saws, mallets, chisels, drills, clamps and whatnot won't make a surgery room a carpenter's shop.

  • "the metal's still burning" Of course it is! IT'S MOLTEN METAL!!! AND IT EXPLODED!!!

  • what a pair of douchebags

  • rofl these kids are retarded

  • No offense, but the two of you are fucking retarded.

  • I love how this video is a total clusterfuck from the start, and the description recognizes ONE mistake.

  • whoever authorized these two amateurs to play with molten metal while disregarding all safety procedures should be fired. they don't even have proper equipment. why isn't OSHA at that lab right now?

  • @methamp How do you know they aren't?

  • @methamp OSHA doesn't give a shit about students. think about it.

  • @methamp They can't get fired....It's a high school.

  • @methamp you didnt use the word amatuer correctly. assuming you meant that they were not doing a good job.

  • @methamp this is a highschool buddy

  • A little mishap while pouring aluminum metal into a cold ingot by an idiot.

  • why would you want to make Aluminium ingots?

  • "You probably just got a hole in your hand....Put It out MAN!!!"

    Cant beleive fucking kids like this are alowed to touch hot shit...or scissors

  • oh goddddd

  • This is why you don't put out burning magnesium with water, the droplets will explode and make the fire worse.

  • "dude i just saved your hand"

  • "Did you have a face shield on" "Uhh...yeah!"

  • Just wow.

  • And how long did it take these idiots to get a fire extinguisher?

  • 'did u have ur faceshield on? ummm, ah, yes (blush)' luck is with the stupid ones, hope u learned ur lesson

  • It is not aluminum. Have any of you seen molten aluminum? Fucking idiot tards. And LOL at the douche trying to put out the fire with his gloves... a glowing red ceramic crucible is sitting on your desk...

  • even the professor was a total moron, asking if he had a regular face sheild on, metal at those temps goes through it to your face like a tank through a screen door!!

    and lab coats, seriously? Come on, you got to invest in some real protective gear

    or you will end up looking like freddy kruger!

  • @jessemc2 face shield = better than nothing!

  • @jessemc2 Lets see a source for liquid metal going "through [a face mask] to your face like a tank through a screen door!!"

    Personal experience and physics/thermodynamics dictate that a blob of liquid metal hitting a Polycarbonate face shield at low to medium velocity will lose its momentum before achieving penetration.

    TL;Dr? most masks will work, but will need to be replaced and removed quickly if the aluminum sticks.

  • @jessemc2 So.. you're the guy who got burned in chem class for not following security procedures and fucking around?

  • @NAMLegolas No I got burned doing metal work before with just slag, it hurts like hell, especially if it goes through the top of your shoe!!

  • 0:01-0:03 umm sorry but im not mexican?

  • You know aluminum doesn't have to be glowing to melt...

  • I like it how the the guy who takes it out has a faceshield yet the guy who is pouring it only has goggles..

  • Geez guys, you should Know by the color of the flask that the metal was way, way too hot and you are lucky you were not seriously hurt..educate yourself to temp indication by color a little will ya huh,,, or better yet get a good immersion temp probe and learn to use it..even a laser temp probe would help..From that white color.just as a guess you were at least 600 to 800 degrees too hot..probably higher

  • wow....... r u seareouly scientists or chem lab partners?
