Oh man, he’s going to be so disspaointed when he gets home and it’s all just rocks. It’s like the time I bottled a piece of a cloud in Costa Rica and opened it up to just find a slightly damp bottle.
Ive reported you to the costa rican authorities for theft of natural beauty you fucking scum
That’s why you’re supposed to get your hair braided into corn rows and a Puka shell necklace to remember your trip. Those last forever.
Those two things really compliment a set of braces and acne.
Is that an OSHA approved hand over the face to keep from breathing the poisonous gas?
I’m kind of surprised it’s not hot enough to boil off all the water in that little bucket pretty quickly, bit obviously it isn’t.
I’m no lavatorial expert, but I’d guess the thermal conductivity of lava is relatively low. The high temp and high mass will keep it warm for a while, but water has a pretty high conductivity and capacity on its own. The agitation is distributing the heat too, well beyond the regular convection rate.
I would guess.
I’m not thinking that “lavatorial” is the correct word.
That conjures “lavatory”, which is something different.
For the science, yeah, more than enough water to cool the lava.
That’s just my experience. If someone does the math, I’ll love them.
If you replace the lava* with shit, the phrase still makes sense and is accurate
Do what math? I honestly don’t know what you guy’s actually expect it to look like, so I don’t know where to start explaining.
Heat capacity of lava per degree Celsius per unit of mass
Multiplied by temperature differential vs ambient, multiplied by mass = total extra heat energy
Then you calculate the sum of heat capacity multiplied by mass for lava and for water, and calculate from that how many degrees above ambient the two masses will land at when combined as the extra energy above is divided over both (assuming water starts at ambient temp)
It won’t be exact because heat capacity varies in materials as temperature changes, both steam and solidification of lava (state change) will contribute significantly, but it’s a decent first estimate
Okay. Then they add more and it will boil quickly. I guess the question boiles (huehue) down to how much water you can turn into stream per amount of lava or the inverse, how much lava you can cool down per amount of water.
The phase change from liquid water to stream will, by the way, not just contribute significantly but be by far the majority of energy needed. Simply heating water up, ignoring the phase change and changes of the heat capacity, with the same energy as it takes to go from liquid to gas (2257 kJ/kg) would result in a temperature rise of… dT = 2257 kJ/kg / 4.2 kJ/(kg*K) = 537 K
Assuming enough water that most of it doesn’t boil, then my math would still check out, but yeah, any substantial amount of boiling forces you do do the math in multiple steps to handle that
Seriously? The lava in water math.
It’s high school stuff if you bother to look up the specific heat and make some reasonable guesses.
It’s masters degree in thermal fluids engineering math

No it’s not. Google specific heat of lava. Shit’s been done already.
And not just for academics. Even Randall Monroe. He’s smart, but he’s not an academic.

Mate, I model thermal processes for a living. The question is: What is the question? What to calculate? What expectations are there to (dis)proof?

Was gunna say, looks like he’s looting the lava more than doing a carefully controlled scientific procedure.
I really have no idea but my guess was the heat.
He might just be shielding his face from the heat. That said, I saw a little plant that almost survived the lava flow, and it was much closer than he was, so idk.
Normally when I see geologists standing around lava they have masks on, so I’d assume he has one under whatever he’s got on his face. Either that or maybe he was getting a couple quick scoops and wasn’t going to be standing around long enough for a mask to make a huge difference.
OSHA completely missed the large ripped hole in the suit by his thigh…
That was from the last guy who did this job and died under mysterious circumstances. Nothing to worry about.
Could also be oil instead of water. I know they use oil to cool off blacksmithing stuff.
I’m a software engineer, not a physicist, but I’m not sure that makes sense for this. Heat does transfer much more quickly in oil than water, so it can cool something off more quickly, but oil can also get way hotter than water. That little bucket isn’t going to hold enough for a lot of thermal mass, so it’s pretty quickly going to get as hot as the lava (or as close as oil can get). Water turns to stream and boils off, so kind of caps the temp under normal conditions.
Plus if they’re doing sampling, I doubt they want the sample covered in oil.
It is water:

Though for steel forging, oil is used depending on how fast they need to cool it down between forging steps.
https://www.americanbladesmith.org/community/heat-treating-101/quenching-oil/
I don’t approve of steel forging, steel customers deserve to know when they aren’t getting the real thing.
What surprises me is no way to carry the bucket away afterward; You would have to put your hand over the bucket, in the steam. Gloved or not, it does not seem very safe.
If it really is just getting the lava down to boiling water temperature, or even a bit higher, that thin metal handle will dissipate that heat pretty quickly. A glove should be fine.
I like that it has its own aluminum foil seal to keep it fresh.
Forbidden pudding.
I want to chew on it like it’s day old banana pudding skin
That’s so weird. Why doesn’t he just fill the bucket with lava? That way he can place a lava source block wherever he wants! Maybe set fire to his friends creations in the process.
Dude just want obsidian quick
Does this hurt the lava?
He ripped its skin away and it’s bleeding all over the place, what the hell do you think?
Lava doesn’t have feelings.
You monster
My lava broke my heart.
So is this how a lava cake is made?
Go home, dad.
All these minecraft jokes and this is who you pick on?
You just have to right click the lava with the bucket, you dont need any special equipment
He’s so abrupt in his movements I was expecting some lava to splash back on his shoe.
I’m more worried about the structural integrity of that bucket after he slung molten lava on the side
The hottest lava gets about 200C lower than the melting point of what looks like stainless steel. And the water inside will actually wick that temperature from the outside into the water pretty effectively.
That’s also why you can boil water in a paper cup by placing it over a flame. The water eats the eat like a hungry jiraffe.
Ooo, you can use a plastic bag, like the kind supermarkets still use, in place of a pot too! Granted, I wouldn’t recommend it because god knows what plastics are leeching out of your makeshift pot and into the water, but if you need to boil water and all you have is a plastic bag, well, there you go!
Considering how plastic trash is literally everywhere now, a survival situation where you have a reasonably intact walmart bag but no pot is more likely than you’d think.
A vital detail you forgot to mention is that water can store an absurd amount of heat even before it boils, and when it starts boiling it stops getting warmer and instead simply takes boils faster and faster the more heat is applied.
It’s honestly basically magic.
and when it starts boiling it stops getting warmer and instead simply takes boils faster and faster the more heat is applied
Isn’t that how most matter behaves? An example of a process that seemingly relies on that, is distillation, which I imagine would be impossible to do, if once the boiling point is reached, the heat didn’t [stop going towards raising the temperature and instead going towards the vaporization enthalpy]
yeah but how often do you go about boiling anything else?
Ah, sorry. I had the impression you were saying that water was unusual in that regard («It’s honestly basically magic» misled me).
Hungry lava giraffe
TIL
He’s cooling lava with an iron bucket of water.
Minecraft confirmed real.
Everytime I see lava, I want to eat it…
Mmmmm… Forbidden snack.
Sounds like a good idea for a community.
Is there a name for the phenomenon where something looks tasty despite not being supposed to be eaten (like soap, I always want to bite soap)
The term is “forbidden snacks.”
I’ve definitely seen similar mechanics with cheese in the toaster
You can only try it once in your life!
You have made me realize i want to do the same.
Forbidden strawberry syrup?
OP this is not mildly interesting, it is fascinating.
Personally I would scoop the lava away from myself but I’m no volcanologist.
With that statement it’s apparent
With those shoes? Damn
As someone who violates his lab’s shoe rules every day, maybe the idea is if he splatters any his foot is fucked regardless?
Maybe not, could make protective covers with insulation. Might help until you cool it down. Lava is between 700 to 1200 celcius. Platinum doesn’t melt until over 1700 celcius. So maybe a layer of insulation inside a thin layer of platinum, then poor some water on it if you get splashed.
I feel like this is from a less well off country with that getup.
I would pay to be allowed to scoop some lava into a bucket. It looks so weird and I really want to poke it. How many people get to say they willingly got to handle lava!
I hiked out to the lava flows in Hawaii when you were still allowed to. It’s pretty cool, but also super scary.
You have to hike for miles over fresh lava flow which creates one of the most difficult terrains imaginable. Imagine rippling hills made of cheese graters and razorblades. And the lava heats the air, so it’s like 130°f. And you have to touch the ground constantly, if it’s too hot to touch or your shoes are melting, or if you hear any cracking, it means you’re likely in top of a lava tube that can crumble away from your weight dropping you into lava.
You have to sit through a 45 minute long safety video before they let you out there, which also explains that due to the heat and the drafts, helicopters can’t get out there, so if you get into trouble, even just succumbing to heat stroke it twist an ankle bad enough that you can’t walk, no one can help you. You need to bring a lot of water.
Lol why were people allowed out there at all
Adults should be able to do dangerous things at their own risk imo
Yeaaah I agree with you honestly. I just imagine Karen wandering in and falling into a volcano because she felt like she was entitled to look at the volcano lol
Self-solving problems are the best problems to have!
He already has some stashed away in his pocket too!
