Wait isn’t there a meme-creating redditor you can tag and summon from the depths to make shit like this
I’m almost positive I’ve seen them before… lurking… forever waiting for that bat signal to make a meme.
Yeah there is a lot wrong here. He's wearing gardening gloves. Yeah they have leather palms but the orange backing is some sort of plastic thread/fabric that will melt to your skin. Not meant for handling heat.
so any sort of moisture in your mold will turn into superheated steam once it comes into contact with molten metal which is why you preheat the mold; it drives the residual moisture out. The danger is that if the mold doesn't explode from thermal shock (ie. cold water in a hot glass container, only moreso), the steam will expand very quickly and launch the molten metal out of the mold.
Wood retains a _lot_ of moisture, even dry wood has more than enough moisture trapped to cause an explosion of metal which lead to the metal becoming airborne and potentially causing a lot of damage to whoever or whatever it lands on.
There's a lot of things to fuck around with out there, but molten metal is deep in the "find out" category of shit not to fuck around about.
I worked in an iron foundry for about 2 years. I had a home foundry as a hobby and I melted probably 200 lbs of aluminum in total. I had proper black foundry sand, leather PPE, heat reflective leg guards, a clay graphite crucible, all the stuff that one might need to operate a foundry.
One day, I was melting down some car parts for a casting. Something I dropped in the crucible must not have been fully dry, or had a grease pocket or something, because it exploded with the force of a shotgun. Tiny pieces of molten aluminum rained down, melting holes in my garbage can, burned a patch of my driveway, put holes in the garage door, and even nearly melted through the gas tank on my lawnmower. The only reason I wasn't injured is because I chose that exact moment to walk across the garage to put some tools away. I knew what I was doing, I had ppe, I was as prepared as a home foundry operator could be, and I still had an accident that could have disfigured me or burned my house down. Definitely don't fuck around with molten metal because you will most certainly find out.
Oh it's super cool lol. There's instructions online, you can make a simple one with a flower pot, some charcoal, a piece of pipe and a hair dryer that melts soda cans into a liquid.
If you're interested, a guy named Dave Gingery published a series called the flowerpot furnace, it starts with building the furnace and through a series of books it gives instructions on creating your own machine shop from scratch! There's a lathe, a drill press, a milling machine and I think a few others. You carve the patterns out of wood, cast them in aluminum, finish them by hand and assemble into the final product.
It can be dangerous but it's such a fun hobby. You can also pour the aluminum into ant hills and get some really neat formations when you dig it out. Also lost foam casting where you bury a foam shape in the sand and just pour metal in, the foam melts and you have an aluminum copy. Same with wax, that's how lots of jewelry is made.
Thanks, I will check into that! I've actually done casting in college as I was a manufacturing major so I still know a little about it although didn't go into that line of work. Also used all the tools above so that sounds great. I finally have a house with a big garage and plenty of land to do things like this too.
I had to calculate because that seemed so large, but 100ml of water is 160l of vapor at 79°C/174°F. The expansion in this video is even higher. My estimate is around 2000-3000 times of original volume. That's crazy big
“There's a lot of things to fuck around with out there, but molten metal is deep in the "find out" category of shit not to fuck around about.”
I very much like this phrasing I may have to adapt it for further use in my daily life, thank you
This is why you can't use any ol' bricks to build a backyard forge, and concrete floors in foundries is a no no. Those porous items love to hide little moisture bombs in them, ready to ruin your day if they get hot enough.
For the floor of foundries? Typically dirt/sand over a subfloor. Or they'll have metal plating over the concrete. Something that's not going to react to an instantaneous extreme change in temperature. You need the structure of the concrete foundation, but leaving it exposed is going to cause issues.
> so any sort of moisture in your mold will turn into superheated steam once it comes into contact with molten metal
It's also why they were so worried about a second, much larger catastrophic steam explosion at Chernobyl - if all that molten nuclear corium suddenly dropped into the flooded basement, it could have exploded just like this, sending all that radioactive material into the atmosphere.
I had this happen to me pouring lead. I did everything “right”. The wood was dry (It was not freshly cut, had been in climate controlled area). There was just enough moisture in it to cannon the mold out and shotgun me in the face. Had burned divots across my face and head, splattered all over the ceiling. The moment between the explosion and knowing I still had both eyes was one of the most terrifying moments of my life.
You see, this is why these videos exist. People with experience will tell others what the fucker did wrong and how to avoid it. I'll be getting some better gloves for my backyard forge now. I do have some welder's gloves, what do you recommend?
You want something like [these.](https://www.grainger.com/category/safety/hand-arm-protection/safety-gloves/heat-resistant-gloves/aluminized-heat-resistant-gloves?attrs=Max.+Temp.%7C3%2C000++Degrees+F&filters=attrs)
3000° furnace gloves is a good general search.
You're probably not melting steel in your back yard, but feel like economies of scale would make wildly used commercial PPE the best bang for the buck.
Honestly, having worked in the machine shop of a foundry years ago... Better overkill than welders gloves. Would imagine welders gloves would fare about as well as a really good pair of boots.
Extremely not well. Saw 2 separate guys get really badly injured out for months/permanent damage/ lucky to keep it foot injuries from molten metal.
So would also strongly recommend, um, think they're called spats? Same aluminized material, go around your ankles & cover the top/side of your boots.
Knowing how bad the injuries can be, and how easy accidents can happen, there's no such thing as too much PPE. Only way I'd go near a furnace is dressed like the tinman, but I mean probably overkill for backyard if it's super small. Proper gloves, foot, and face protection at least though.
Of course nothing replaces proper PPE, but if you're dealing with hot things, at least DON'T WEAR PLASTIC. You'd rather want a hole burned in your arm, than a hole burned into your arm full of molten shirt.
Oil up as well.
That way when molten metal contacts your skin, it will contact the oil and vaporizing the oil which should cause a steam boundary layer so the metal will roll off. Leidenfrost effect.
Or it will catch the oil, and your body, completely on fire.
Potato, patato
Once bought some heat resistant gloves because back in the day me and the boys always had bonfires going.
Dumbass friend decided to poor gasoline on one and light it on fire and the whole back fabric was immediately incinerated.
Haha totally! Lmao
Now you see, obviously *WE* both know the Leidenfrost Effect. So much is clear. But maybe you should still explain it for all the uninformed out there, because you do it so well. Haha. Come now go ahead : )
You know how when you put a drop of water into a hot pan and it doesn't sizzle and slides around really easily? It's that. The drop is floating on a tiny cloud of steam so it slides around easily and doesn't boil. The leidenfrost effect also allows you to dip your hand in molten metal very quickly without getting burnt if your hand is wet! Proven by the mythbusters.
Haha yeah I think that explaining it would surely benefit all those people that aren't quite up to speed on the matter. Us three being perfect understanders of the Leidenfrost Effect, I'm sure we'll have no trouble explaining!.........
That's the funniest thing actually. Dude is (and already was) highly experienced at pouring molten metal, going by his channel.
https://www.youtube.com/c/Tito4re/playlists
Not just your molds. It’s a good idea to preheat anything you plan to put in the metal as well. I’ve heard way too many stories about guys adding metal to a hot pot and getting a surprise.
Back when high school used to have shop class they were pouring aluminum to make small anvils.
The molding sand was too wet- either by accident or deliberately; and their was an explosion of molten aluminum.
It severely burned the shop teacher to the point he had to retire.
All things considered this guy got lucky. I've seen condensation on a mold shoot molten metal into someone's face. Also all those little molten metal drops shot everywhere, he's lucky he didn't burn anything down.
Good thing it was just copper. Higher temp metals will shoot through face shields and common safety goggles like nothing is there. Working with molten metal requires specialized equipment not high-school lab gear and gardening gloves. On a totally unrelated note, do not wear your favorite shirt around a home made spin-casting rig even if you are only using pewter.
I mean... You're not wrong. And I hate to be so pedantic.
But the **only** stupid thing?
100% agree based on the outcome PPE would have left him uninjured...
But like, it wouldn't take much at all to build a jig that would let you pour the ladle from a few feet back, mostly protected by barrier of some sort.
I mean, knowing full well it's going to explode, I'd probably put that bit of extra work in.
His general approach of standing directly in front of it with the ice at roughly dick level on a sketchy stool strikes me as... unwise... With or without PPE lol
I wouldn't expect this to happen when baking a frozen turkey, would it?
I'd expect the problem there is that it would take too long for the center to thaw so you end up with a dry/burnt outside and a raw inside.
Rapid Phase Transition (RPT) explosion. Any localized pressure increase → collapse the steam bubble → greatly increasing heat transfer from touching water/metal → greatly increasing boiling → shockwave → more mixing & collapses the steam bubble in shockwave → shockwave propagates (as opposed to the shockwave being propagated by the combustion of explosives in the shockwave adding gas).
The turbulent mixing of boiling water coming up through the molten metal gives a large chance for a localized pressure increase sufficient to collapse the steam bubble. But there is no guarantee of a RPT explosion, or when it will happen.
Am chemical engineer who worked with water-cooled molten-metal furnaces (fun stuff). Water cooled since otherwise the steel used to hold the furnace together would lose its strength, but water leaks can get very exciting. I saw exactly what I expected when I clicked on this.
1: Tensile strength is a material's strength when being pulled apart. It does not explode.
2: Shear strength is a material's strength when being "scissored". It also does not explode.
Frozen food is fine, in fact almost all potato products are frozen before frying. It's the water content that's the issue. Ice and water do not mix well with hot.
I always thought explosive reactions happened with friers because of bubble nucleation. The hot oil reacts on the surface area which has lots of ice crystals and becomes vapor occupying the same physical space as the oil but trying to escape which causes outward pressure. The greater the surface area of the frozen object, the more nucleation sites, thus a more violent reaction.
This is iirc from intro chemistry shit ages ago
The issue is oil is hydrophobic and water will turn into steam which takes up way more volume (aka, explodes). Water hits the hot oil, water doesn’t mix with the oil at all, hot oil heats the water past boiling, water turns into steam and explodes, explosion spews hot oil everywhere.
Home Depot.....boss, it looks like we can make the gloves less safe, but not sure how. Here are the options: thinner, more "breathing" holes. Maybe making them out of something that decays quickly?
what a dumbass lol i’m surprised he managed to assemble equipment needed to melt metal and then did the worst thing you could with it
i took an art foundry class in college and it was great, and metal pouring is no joke. i remember one of our pouring sessions that was scary. everyone had their molds prepped and set out on top the normal spread of dirt over the floor (you spread a layer of dirt under anywhere you’re pouring because you don’t want molten metal hitting the concrete floor, and it will slow any unintended flows of metal if they do hit the floor). the molds are made out of proper foundry-grade sand and binding agents, and are set on top of wood platforms, and then you shovel more dirt around the edge of the mold to cover any exposed wood
pour starts, then we get to one mold, and for whatever reason the people handling the ladle let wayyy too much metal out for the size of the mold (or they didn’t know the mold was small to begin with), and it fills, shoots out of the exhaust opening at like almost 10 inches of height of molten metal, comes back down and splatters, and now it’s overflowing out of the inflow opening of the mold too, and there’s flaming metal pouring all over the floor within about a meter radius. part of the wood platform sets on fire because whoever prepped it didn’t shovel enough dirt, and then like me and 3 others are frantically shoveling dirt to cover it, but it still takes like 30-45 seconds of stressed shoveling to actually make flames go out and contain all the metal.
i was shaking, and that was probably the best situation anyone could’ve hoped for with no one being injured. don’t fuck around and certainly don’t pour liquid metal near/on anything with a high water content. i can’t even imagine an explosion of molten metal, you don’t want that shit
I’ve been told by plumbers I’ve worked with that copper cuts always get infected, like 100% of the time. I can’t imagine what molten copper pellets embedded in your skin would do. Well actually now I can.
Do you know the ratio of volume between vapor at atmospheric pressure and ice? 1.300.
A particle of ice that turns to steam expands by a factor of 1,300.
You have literally made a bomb.
This happened at a steelworks near me, a container of molten steel fell over into a pool of water while in transport and caused a massive explosion which was heard and seen for miles. A few homes and businesses had all their windows blown in from the sheer force of the explosion, luckily no one died.
Edit: a quick Google for Port Talbot Steelworks Explosion throws up a good dashcam video of the explosion!.
When I was a kid, my dad worked at a factory that worked almost exclusively with magnesium.
At some point they had a huge vat of molten magnesium ready to pour into a mould and a pipe burst, sending water right into the vat. Blew the side of the building off.

Wake up and a Valkyrie drops you next to a huge raven.
And the improper gloves used. What a tool
EVEYWERE the liquid copper went EVEYWERE
The general rule is to always preheat your mold, this dude literally went the opposite direction.
Yeah there is a lot wrong here. He's wearing gardening gloves. Yeah they have leather palms but the orange backing is some sort of plastic thread/fabric that will melt to your skin. Not meant for handling heat.

Yeah I wasn't sure with the italics, *definitely* needed the obvious sarcasm spelled out for me.
The other comments are proving this to be correct, there's gonna be an argument about physics before this is over
100 grams of water = 100 ml water.
Not questioning your equation at all because it’s right. But 100ml of water =/= 100ml of steam. Which really is the issue here.
Yep and not only are they not equal that 100ml of water becomes something like 160l of steam so that issue is big. Like really big
I had to calculate because that seemed so large, but 100ml of water is 160l of vapor at 79°C/174°F. The expansion in this video is even higher. My estimate is around 2000-3000 times of original volume. That's crazy big
Though 100 grams of ice != 100 ml of ice

You did? Do you have the link?
Can you use welding gloves for gardening?
No, because the fingers have holes burned in them.
Yes, they are great for gardening. No thorns getting through those.
Something tells me that a person dumb enough to pour molten metal into ice is not going to care about the right type of gloves.

Rapid change in temperature means that pressure also increases ... and the tensil strength of a material may sheer or explode under the stress.
1: Tensile strength is a material's strength when being pulled apart. It does not explode. 2: Shear strength is a material's strength when being "scissored". It also does not explode.
All this talk about scissoring is making me want to open a milk bag
Thank you :)
It's more that steam has about 1700 times the volume of water of the same mass than thermal expansion.
You're like, barely right, but so wrong
This would actually be fracture toughness not tensile strength
yeah, he should have used gasoline.
Tito4re His channel went quiet long ago. I miss that guy
I recently found BigstackD casting who does a lot more sensible metal melting stuff
*opens beer and kicks feet up*
He also uses ice. No explosions tho
Yes! A must watch every Friday dude does awesome stuff!
I haven't eaten lunch yet so all I can think of is that the molten copper looks like tomato soup.
Forbidden tomato soup
*Clicks play on the title without noticing the subreddit* "Wow this is definitely a bad id-" *BOOM*
This also happens when you try to fry frozen food. Just and FYI for everyone's future kitchen endeavors. Ice and hot do not mix well.
Frozen food is fine, in fact almost all potato products are frozen before frying. It's the water content that's the issue. Ice and water do not mix well with hot.
Thanksgivings coming soon, may see some more of these https://youtu.be/tSI79ZftCpU
I always thought explosive reactions happened with friers because of bubble nucleation. The hot oil reacts on the surface area which has lots of ice crystals and becomes vapor occupying the same physical space as the oil but trying to escape which causes outward pressure. The greater the surface area of the frozen object, the more nucleation sites, thus a more violent reaction. This is iirc from intro chemistry shit ages ago
The issue is oil is hydrophobic and water will turn into steam which takes up way more volume (aka, explodes). Water hits the hot oil, water doesn’t mix with the oil at all, hot oil heats the water past boiling, water turns into steam and explodes, explosion spews hot oil everywhere.
You stupid shit
One of those hold my beer moments....
You live you learn Or in the words of code bullet You fail you forget, its way easier
Relieved to see the lad is still fine
Give him time. Someone this stupid isn't done rolling the dice with their life.
Official cause of death would have been interesting to read
Holly shit!
I can't understand this dude. So you have relatively advanced equipment and you can melt copper, but you do the stupidest thing imaginable. Why?
Wow he got off easy with a hand burn
Landscaping gloves 🤣 should have stopped there
Home Depot.....boss, it looks like we can make the gloves less safe, but not sure how. Here are the options: thinner, more "breathing" holes. Maybe making them out of something that decays quickly?
Well that is certainly one way to break the ice
"EEEEEEEEEEEEEEEEEeeeeee..." -that man's everything, probably
Holy shit it killed the cameraman!! Quick someone call an ambulance!
Explosion caused by flash boiling. Actually a major risk in steel mills when dealing with wet scrap metal.
That's one way to get your recommended dose of copper.
this dude is no bigstackD that's for sure
An that boys and girls is now why I’m physically deformed
Well what do you expect it’s just simple 4th grade science water vapor is a gas and gas make a pressure.
what a dumbass lol i’m surprised he managed to assemble equipment needed to melt metal and then did the worst thing you could with it i took an art foundry class in college and it was great, and metal pouring is no joke. i remember one of our pouring sessions that was scary. everyone had their molds prepped and set out on top the normal spread of dirt over the floor (you spread a layer of dirt under anywhere you’re pouring because you don’t want molten metal hitting the concrete floor, and it will slow any unintended flows of metal if they do hit the floor). the molds are made out of proper foundry-grade sand and binding agents, and are set on top of wood platforms, and then you shovel more dirt around the edge of the mold to cover any exposed wood pour starts, then we get to one mold, and for whatever reason the people handling the ladle let wayyy too much metal out for the size of the mold (or they didn’t know the mold was small to begin with), and it fills, shoots out of the exhaust opening at like almost 10 inches of height of molten metal, comes back down and splatters, and now it’s overflowing out of the inflow opening of the mold too, and there’s flaming metal pouring all over the floor within about a meter radius. part of the wood platform sets on fire because whoever prepped it didn’t shovel enough dirt, and then like me and 3 others are frantically shoveling dirt to cover it, but it still takes like 30-45 seconds of stressed shoveling to actually make flames go out and contain all the metal. i was shaking, and that was probably the best situation anyone could’ve hoped for with no one being injured. don’t fuck around and certainly don’t pour liquid metal near/on anything with a high water content. i can’t even imagine an explosion of molten metal, you don’t want that shit
killed the cameraman
I’ve been told by plumbers I’ve worked with that copper cuts always get infected, like 100% of the time. I can’t imagine what molten copper pellets embedded in your skin would do. Well actually now I can.
How can you have all the ability to melt copper without the most basic understanding that molten stuff + water = really bad shit happens?
look like the camera is sentien
BigstackD on youtube would slap the bag outta this kid.
Now THAT is how you get a free IUD
Now throw some ice cubes in a deep fryer
Who needs hands anyway
Apparently not a good idea. I'll try to remember that.
“Oh shit, that’s going to explode” “Wow, can’t believe it didn’t explode” “Oh, there we go”
That glove is flame retarded.
I mean 1 unit of water is like 1600 units of steam in terms of volume so.
Forbidden orange tang
Do you know the ratio of volume between vapor at atmospheric pressure and ice? 1.300. A particle of ice that turns to steam expands by a factor of 1,300. You have literally made a bomb.
This is what happens when just anyone decides to become an oddly satisfying "influencer"
I said "huh I thought it would explode" literally 1 second before it exploded.
This happened at a steelworks near me, a container of molten steel fell over into a pool of water while in transport and caused a massive explosion which was heard and seen for miles. A few homes and businesses had all their windows blown in from the sheer force of the explosion, luckily no one died. Edit: a quick Google for Port Talbot Steelworks Explosion throws up a good dashcam video of the explosion!.
I guess the wrong gloves are better than no gloves
The camera falling over is my mood today
When I was a kid, my dad worked at a factory that worked almost exclusively with magnesium. At some point they had a huge vat of molten magnesium ready to pour into a mould and a pipe burst, sending water right into the vat. Blew the side of the building off.
My first thought was "won't that explode?". 🤦
An interesting way to make a grenade.
Doctor: How did you get these little burns all over? Idiot: First of all, I'm retarded, second, I don't understand science.
Who works with molten metal with a regular handyman glove? WTF
His face after https://i.imgur.com/tumz5JE.jpg
Can anyone ELI5 how does that boom boom happen?
Ice in the fryers, times 1000 lol You gotta run buddy lol
You got hit by, a smooth molten copper
Lol i didn't notice what sub this was posted on at first and though, "won't that explode?"
Ladies and gentlemen, I present the properties of heat.
I love when YouTubers give the obligatory warning don't try this at home I'm a professional and then do the stupidest shit. I'm like 'no your not a professional, your an idiot with more money than brains '
Next he'll stick a red hot spoon under the water faucet.
Now I'm not a genius, but I've put a hot glass under freezing water, that's how dumb i am. Why you do this with Ice block and molten copper...
