- It made a mini lava lake. This is so cool!
- Oh my god! What's gonna happen? Yes, yes, yes, yes!

- Ooh, what's that? - What is it? Just scrap metal?
- Ooh, that's cool. - What is this?
- We gonna do some science [bleep]? - Is he gonna set something on fire--
(excited) Is he gonna blow stuff up?! - Oh, is he like a blacksmith?
This looks like hot metal. I'm intrigued.
- Ooh, he's gonna gas that thing.
- Ooh, that's hot. You better be wearing safety gear, my guy.
- Ooh, that thing's probably hot. Woo!
- Whoa, what? - Ooh! Ah!
- He sent small. Little bits. Little bits.
Oh, come on. Dump it all at once. - Oof.
My bath water. - What's it supposed to be doing?
- I thought there would be more steam to be honest.
(loud tinkling) - Why's it sound like that?
- That little tinkling sound, that is like what volcanic glass
sounds like, like obsidian. People like to think about obsidian.
It's not gonna be like this. It's not formed that same way.
- Ooh, ooh, ooh.
- That just makes me wanna go smoke hookah, honestly.
- What did we make? What did we make?
- Whoa. - (man) Whoa.
- What the hell? - Whoa, that looks awesome.
- That looks like something my cat would throw up.
- It seems like he's just doing something to do it.
- The metal just fused back to itself.
- That thing about to disintegrate? - It's just falling apart now.
That was like lava? - I'm impressed.
I've never seen anything like that. They like reverse smelted it.
- I'm a volcanologist, which means I'm a scientist
who studies volcanoes. Real lava is gonna--
sometimes, it'll flash into a steam explosion
called phreatomagmatic eruption, which is the coolest thing.
But this, he's just trickling it in there.
- (FBE) So, we have more videos to show you in a second,
but that was a lava versus pool experiment video.
- I like it. That reminded me of the Big Brother pool,
you know, like the tiny pool they have in the backyard?
- (FBE) But that was a lava versus pool experiment video,
which has more than 82 million views as of filming this episode.
- 82 million.
Eh, could be better. - (FBE) There seems to be
a very popular subcategory of videos on YouTube,
where material is melted into lava and poured
over various objects to yield different results.
- Oh! Okay. I like that. - That's cool.
That's interesting stuff. I like this content.
I'm here for it. - That's interesting,
because I don't get to play with molten whatever every single day,
so it could be interesting to see what happens when you pour it
on a birthday cake. - I'm looking forward to these videos,
because there is so much that is not understood
about lava in the public's mind, right?
I mean, if you look at the movie Volcano
with Tommy Lee Jones, they stopped flowing lava
with concrete barricades and fire hoses.
And that isn't gonna happen. So, that's just one example
of how everybody thinks the wrong thing about lava
unless you spend some time with a volcanologist.
- (FBE) So you ready to see some more? - Yeah.
I wanna see things melt.
- Looks like just rock. - Okay, that's actual basalt.
Cool. We're starting with lava that's already cooled and solidified.
- Ooh, okay. Some dry ice. - Dry ice. Oh, yeah.
That dry ice ain't no joke. - I'm actually very curious
to see what happens now. - I love dry ice in a cocktail.
Oh my gosh. Bring me that smoky margarita.
- He trying to figure out which one is stronger,
the lava or the ice? - How hot is that? I wanna know.
Like, I have questions for these people.
I need answers, people.
- What's gonna happen? - I have seen videos similar
to this, but just not something like this,
like that 1,000-degree knife. - Ooh, it's gonna hyper-cool.
- Ooh, that looks like frosting. - Looks very sci-fi.
- This is nuts. - Ooh! It's so cool and blobby
and globby and... I wanna touch it,
but obviously don't touch it. - So yeah, the bottom of it,
I bet, is already starting to solidify and the top
will be a little more oozy longer. - I think this is more entertaining,
because the other one, I couldn't see the lava inside the pool.
- It's like one of 'em steaks, them ribs.
- Lavagirl eats those. ♪ (rimshot) ♪
(snickers) - A little anticlimactic. (chuckles)
- That's really cool. That looks awesome.
The ice was like, "Not today. You gonna be shaped like us."
(laughs) - That thing reminded me of a souffle.
I like how just the outer layer hardens.
- It's really interesting that the cold has
a more powerful effect than the lava,
'cause you're like, "Is the ice gonna melt
or is the lava gonna freeze?"

- But what's this? Like, what is this that they're putting
in there? Is it some kind of metal?
- Is this just more lava rock?
- He's not even wearing protective shoes.
He has Nikes on. - All the music just makes me
wanna dance, though. It's pumping me up.
- Ooh, a watermelon! Changing it up!
- Let's make a guess. What's gonna happen?
I think it's gonna explode. - I feel like it would explode.
Well, I guess it has an opening, but, like...
- I want it to explode, but unless they cap it somehow,
it's not going to, 'cause the gas won't be able to build up inside.
You won't get enough pressure. - Oh my god! What's gonna happen?
Is it gonna burst? Is it gonna hold its shape?
(gasps) What's gonna happen? - It didn't break through.
It just stayed insi--
What? - That looks cool too.
It's just like... It looks like it's alive.
It's like (makes crackling noise). - It's like a tiny volcano.
- Oh, that's cool. It's like forming a little mini lava lake.
The surface is roiling, because it's so hot.
Oh, I love it! It's making a lava lake!
It made a mini lava lake. This is so cool!
- Is it not gonna leak out? That's insane to me.
- Oh, oh, oh, oh, oh. Oh. Oh, god.
- You sure that's a real watermelon? - You're telling me nothing happened?
- I just wish there was some scientific study
that would relate to this. I mean, our studies usually involve
trying to keep people from dying. We don't get to do fun things
like pour lava in a watermelon. - Whoa!
- (men) Ooooh. - (laughs) They're so excited!
- Ooh, what if it explodes? (gasps) That would be awesome.
- I don't even know why, this is making me hungry.
That's clearly not food. - How the [bleep] did the watermelon
hold its shape? - I'd very badly scorch my hand,
but I wanna just... - That's a real watermelon?
Y'all fact check this? - They're pretty interesting to watch.
I wanna see what else they do with 'em.
They must take it to the extreme, huh?
Get pretty crazy?
- Ooh, what's that? Is that co-- ooh, it's cooper.
Okay, okay. - I just wanna say copper is not lava.
So, if anyone's watching this, lava does not have that high
of a copper concentration in it. Usually, it has a lot of iron,
a lot of manganese, and some silica, but very, very-- just trace amounts
of copper for the most part. - What is that? Are those Orbeez?
- Are those Orbeez? Those look like Orbeez.
- My kids be playing with those.
- So, copper and squishy beads. I've definitely never done
anything like this in the field. - What? That's so cool!
- Yes! Burn the Orbeez. - I don't think this one's
gonna be cute. - Oh, it's gonna melt all the plastic.
Oh, it's gonna be one solid unit. Oh, come on. Yes.
- Oh, whoa. Whoa!
- (chuckles) Ohhhh, whaat?! Ah!
- "Incredible." That is [bleep] nuts.
- It's like gold stuffed with marbles. Okay. My new favorite kind of jewelry.
- Why's it turning gold? Why's it gold?
- I would literally put that on a shelf and shine a bright light
on it and make it like art. - This is more entertaining.
This is cooler. They're all stuck. It's very colorful.
It's a little bit more gold. - That's so awesome. (chuckles)
I wanna do these experiments now. - That one was my favorite so far.
I love colors and gold. - Now I'm just impressed
with all these things he's pouring the [bleep] in
and nothing's happening. It's kind of blowing my mind.
- I always thought that lava was just gonna kinda destroy
everything that it touches, 'cause it's so [bleep] hot.
But I guess that's not the case. - I'm thinking about all the things
that you shouldn't put in lava. Like, I lost a pocket knife
in a lava flow once and watched it just get eaten
by the lava. So, usually, I'm trying to keep stuff out
of lava instead of what's going on here,
but now I kinda wanna put stuff in it just 'cause you can. (chuckles)
♪ (upbeat music) ♪
- Are these fireworks? - Ooh! Okay, fireworks.
- Yes! Explosions! (chuckles) I'm so excited!
- Okay. I'm a fan of fireworks and fake grenades.
- Oh my god. What's gonna happen? (claps) Yes, yes, yes, yes!
(fireworks popping) Run!
(loud pop) Ah!
- Oh! Yeah, he had the right idea. Just run.
- (laughs) He took off running.
- Oh my-- (stutters). - (chuckles)
Love that.
- Cool. - That seemed like a really bad idea.
I'm glad he was using small fireworks instead of large ones,
'cause if he had been using, like, an M-80, he would not--
part of him would be missing right now.
- Yay! (claps) These are fun! Ah, more ways to waste my time
on the internet. I look forward to it. (chuckles)
- Throughout high school, I was really interested in chemistry
and all that stuff, so just seeing it, I feel like it gets people
more interested into learning more about it.
- Not a lot of people have that stuff,
so it's interesting to see how it reacts with different things
and water versus a watermelon versus Orbeez and firecrackers
and stuff like that. It's cool. - It's interesting that these
sort of niches happen on the internet. And I think it's strange,
but 86 million other people watched this and thought
it was the coolest thing. - (FBE) So, these types
of lava experiment videos that combine molten material
with objects, foods, etc., they seem to be garnering tens
of millions of views on YouTube. - Unsurprising.
- (FBE) Why do you think these are so popular?
- Who knows? I just think people just ain't got nothing else
to do but just watch stupid videos. What are people gonna get out of that?
Nobody's gonna do it. - It's a satisfying video,
because you are interested to see what's the outcome
of "What happens if I do this?" - It's the Earth creating
and destroying. And that power to do both at the same time
is so unique to volcanoes. I think that's why people
are just fascinated by this stuff. I wanna see what happens! I'm curious.
I mean, we're all curious, right? We're all born as scientists,
so we wanna know what happens when two different things come together.
- Nobody can really recreate this. It's really difficult to do.
You're not just running around with a kiln in the backyard
and molten metal lying around. So, things that are out of the realm
of what you could do yourself are far more fascinating to me.
- (FBE) So, Jess, we're so happy to have you and your expertise
as a geologist and volcanologist for this episode.
- Yay. It's great to be here. I mean, it's always fun
to come talk about lava. I think what's really interesting
is that there is a little bit of science underlying some of this
in that I could look at a lot of these interactions and have an idea
of what the outcome would be because of how lava acts in nature.
So, when I see it going in contact with something
like a plastic, I'm like, "Oh, lava melts plastic."
Like, duh. That's what happens in real life, so, of course,
that'll happen in their experiment. Or in a watermelon, a closed area,
you get a little lava lake, because you formed a little chamber,
a magma chamber, for it. - (FBE) So finally, what subcategory
like this do you like watching on YouTube?
- I like watching cooking videos, a lot to do with food.
And it's really bad, 'cause I typically watch them
when I'm really, really hungry, and it's just a recipe for disaster.
- Definitely just those visually appealing things like this,
like the hydraulic press, the 1,000-degree knife.
- Occasionally, I'll see the hydraulic press ones,
and they'll put like bars of soap under the hydraulic press
and see what happens. - I remember when I was here
and I watched different ones when I was high.
They told us to watch different high videos.
She workin' that street! She's gonna make everyone
look at her. - Well, I like the ASMR stuff
if the noise isn't creepy, and I love gels and globs and blobs.
And I love the magic sand stuff, where you think it's just gonna
be a total mess and it comes out so perfect.
- I was introduced to mukbang through ASMR.
I think I enjoy the mukbangs better than the--
I hope I'm saying this right. It's the connection through the "Mmm."
- I like to watch science experiment videos too.
I really like the Slow Mo Guys, where they take different experiments,
and they just make it like... Like, the ones-- I think my favorite
is when they have a water balloon and they throw it
at each other's faces and see how the human face reacts.
