[00:11] Suika
    You can see so far away!
[00:15] Suika
    The sun's gonna rise soon!
[00:18] Senku
    Don't look at the sun through the telescope.
[00:21] Kohaku
    If the stones you guys got
    are the right ones...
[00:30] Ruri
    Wow, it's like a mountain of jewels.
[00:33] Senku
    It's not like a mountain of jewels.
    It is a mountain of jewels.
[00:37] Senku
    It's a treasure trove of super rare metals.
[00:42] Magma
    Jewels, my ass.
[00:44] Magma
    They're just slightly heavy rocks.
[00:46] Magma
    After all that fuss...
[00:48] Gen
    We're going to win against
    Tsukasa-chan's army with these rocks.
[00:52] Kokuyo
    With these rocks?
[00:54] Kokuyo
    I see.
[00:55] Kokuyo
    With these gems!
[00:57] Kokuyo
    I can see them being heavy
    enough to really hurt.
[00:59] Ruri
    Father, I don't think that's what...
[01:01] Kohaku
    You can't blame him.
[01:03] Kohaku
    Father is of an older generation.
[01:05] Kokuyo
    What?!
[01:07] Gen
    We're up against Tsukasa-chan's army.
    They're going to be seriously tough.
[01:11] Gen
    Our plan is to make cell phones using
    these rocks and win the information war.
[01:18] Kohaku
    But, Senku, how much longer is it going
    to take to make our cell phones?
[01:22] Ginro
    She's right.
[01:23] Ginro
    Once spring comes, Tsukasa-kun's
    army is going to be rushing in.
[01:27] Senku
    The goal's not that far away.
[01:29] Senku
    To put it simply...
[01:30] Senku
    The vacuum tube is the
    heart of the cell phone.

[01:39] Senku
    With these four body parts,

SIGN    Wave of Science
[03:32] Senku
    First, we're going to make the filaments,
[03:34] Senku
    which are essential for the vacuum tubes...
[03:37] Senku
    using tungsten, the most heat-resistant

[03:45] Kohaku
    But, Senku, how are we going
    to get it out of the stone?
[03:49] Senku
    About that... It's going to be tough as hell.
[03:53] Chrome
    What the hell are you two doing?!
[03:56] Magma
    We're getting it out of the rocks, aren't we?
[03:58] Magma
    All we need to do is destroy it.
[04:01] Senku
    I mean, that works.
[04:03] Senku
    We'll be turning it into powder, anyway.
[04:05] Magma
    See? I was right!
[04:07] Ginro
    No one asked you!
[04:09] Kohaku
    What if you'd been wrong?!
[04:13] Kokuyo
    This is unusual.
[04:15] Kokuyo
    He's hardly doing it right,
    but I've never seen him offer to help.
[04:20] Kokuyo
    Did something happen in the cave?
[04:23] (Flashback) Senku
    You get to see all the insane stuff
    that humanity worked together
[04:26] (Flashback) Senku
    for two million years to build.
    Stuff you never would've seen otherwise.
[04:30] (Flashback) Senku
    And I'll show you so much of it,
    it'll make your head spin.
[04:34] (Flashback) Magma
    Senku!
[04:35] (Flashback) Magma
    I don't care if you're the boss anymore.
[04:38] (Flashback) Magma
    At least, until we deal with that Tsukasa guy.
[04:42] Senku
    Gee, I don't know.
[04:45] Magma
    We're done.
[04:47] Magma
    What's next?
[04:48] Senku
    I'm going to do chemistry stuff
    to this powdered blue rock
[04:51] Senku
    to turn it into something
    resembling toothpaste.
[04:54] Gen
    Right, you're doing chemistry stuff.
[04:57] Gen
    The stuff it wouldn't do me
    any good to ask about.
[05:00] Senku
    Lastly, we're going to get rid of the rust
    on the toothpaste stuff using hydrogen,
[05:04] Senku
    warm it up in a glass container, and it's done.
[05:08] Senku
    It needs to be at least 1,000 degrees.
[05:10] Senku
    The hotter it is,
    the stronger the tungsten will be.
[05:14] Kaseki
    So all we have to do is cook it.
[05:17] Chrome
    Hey, it's actually pretty easy.
[05:19] Senku
    What are you, stupid?
[05:21] Senku
    What would happen to a glass container
[05:23] Senku
    if you threw it into a fire
    that's 1,000 degrees?
SIGN    Tungsten
SIGN    Glass
[05:29] Senku
    We have to heat up just the tungsten
    toothpaste inside the glass container.
[05:34] Kaseki
    Then we need a heating mechanism
    with pinpoint accuracy.
[05:37] Kaseki
    How do we do it?
[05:38] Senku
    We don't have time. Let's split up the work.
[05:41] Senku
    I'll deal with the
    toothpaste-making chemistry stuff.
[05:44] Chrome
    So who's making the
    pinpoint heating mechanism?
[05:48] Chrome
    Are there any other science users?
[05:56] Senku
    Chrome, you know everything you
    need to make one from scratch.
[06:00] Senku
    Throw all the science tricks
    you've learned at it.
[06:04] Senku
    Or do you need Senku-sensei's help?
[06:09] Chrome
    Don't make me laugh.
[06:12] Chrome
    I'm Chrome!
[06:13] Chrome
    I'm a smart-as-hell science user!
[06:18] Chrome
    Don't come crying to me for help at your lab.
[06:22] Senku
    Yeah, I got the lab stuff.
[06:25] Senku
    I'm leaving you in charge of the heating team.
[06:31] Kaseki
    You make me jealous.
[06:36] Kaseki
    You know, I've always loved
    making things, even as a kid.
[06:44] Kaseki
    I made all sorts of things—bridges, shields—
[06:47] Kaseki
    so that people wouldn't look at me funny.
[06:50] Kaseki
    Thanks to that, I get to pretend I'm
    still in the game, even at this age.
[06:57] Kaseki
    But to be honest, I can't help but
    wish I had a maker buddy, too.
[07:06] Chrome
    But you have two friends, Old Man Kaseki.
[07:09] Chrome
    Maker buddies.
[07:12] Kaseki
    Two?
[07:13] Kaseki
    Where?
[07:17] Chrome
    Right here.
[07:23] Kaseki
    Me?
[07:24] Kaseki
    Even though I'm almost
    fifty years older than you?
[07:28] Chrome
    Our age?
[07:28] Chrome
    That matters somehow?
[07:59] Chrome
    What the hell?!
[08:03] Gen
    He's even more gung-ho than usual.
[08:07] Senku
    Come help me over here, modern man.
[08:10] Senku
    You must know at least a little
    more chemistry than the villagers.
[08:13] Gen
    I'm not sure.
[08:15] Senku
    There's a ridiculous number of steps.
[08:17] Senku
    I bet you won't get a millimeter
    of this, so I'll make it simple.
[08:21] Senku
    Cook the blue gem powder
    in sodium hydroxide;
[08:24] Senku
    use sea shells, hydrochloric acid,
    and ammonia to crystallize it;
[08:26] Senku
    and then bake it and mix it with honey.
[08:30] Gen
    Okay! I understood all of that, Senku-chan.
[08:34] Gen
    Honey! Bake it, and then honey.
[08:37] Gen
    I got that much.
[08:39] Senku
    Chrome's definitely ten billion
    times more useful than you.
[08:42] Gen
    Nah, I don't think anyone
    could have kept up with that.
[08:46] Gen
    You're the only one who gets it, Senku-chan.
[08:50] Chrome
    Nothing beats this when it
    comes to pinpoint heating!
[08:53] Kokuyo
    There it is! Chrome's special move!
[08:56] Magma
    Quit showing it off.
[08:57] Magma
    You're reminding me of bad times.
[09:01] Kaseki
    I don't know how much
    heat it produces, though.
[09:05] Kaseki
    Let's set up some metals
    in order of heat resistance
[09:07] Kaseki
    so we can measure the temperature.
[09:22] Suika
    It's not even doing anything to the lead,
    and that's the weakest one.
[09:26] Kaseki
    It's winter, after all.
[09:28] Kaseki
    If we just had a little more sunlight...
[09:33] (Flashback) Senku
    Throw all the science tricks
    you've learned at it.
[09:37] Chrome
    We're using fire, too.
[09:39] Chrome
    Add the cotton candy machine
    to the pinpoint heating!
SIGN    Blorp...
SIGN    Lead
[09:45] Chrome
    Damn! We need more than just me and Suika.
[09:48] Kaseki
    We defeated the lead, though.
SIGN    Blurrp
SIGN    Gold
SIGN    Silver
[09:51] Suika
    Wow, we beat gold and silver!
[09:55] Chrome
    Good going, battle team!
SIGN    Blurrgh
SIGN    Iron
[09:57] Ginro
    We made it to iron!
[09:59] Chrome
    Go, gorilla team!
[10:03] Kaseki
    We made it past 1,000 degrees!
[10:06] (Flashback) Senku
    It needs to be at least 1,000 degrees.
[10:08] (Flashback) Senku
    The hotter it is, the stronger
    the tungsten will be.
[10:12] Chrome
    No, we need more.
[10:13] Chrome
    Add electricity power!
[10:22] Senku
    All right, it's done!
[10:24] Senku
    Tungsten toothpaste!
[10:27] Senku
    How are things on your side, heating team?
[10:29] Chrome
    We're just about done.
[10:31] Senku
    Not bad, science user.
[10:38] Senku
    What the hell is this
    all-of-the-above mega set?!
[10:41] Chrome
    Senku, you were the one who
    said to throw everything at it.
[10:45] Senku
    This isn't what I meant.
[10:47] Senku
    This thing's ugly as hell.
[10:53] Senku
    Honestly, though, this might
    actually be the best solution.
[10:57] Senku
    If the goal is for all of us to join
    together to raise the temperature...
[11:03] Senku
    We're going to make a long,
    thin blob of tungsten toothpaste.
[11:06] Senku
    Zap water with electricity,
    and it'll produce hydrogen.
[11:09] Senku
    That hydrogen, with a lot of heat,
    peels the rust right off the toothpaste.
[11:13] Chrome
    Here we go. Pinpoint heating...
[11:16] All
    ...to several thousand degrees!
[11:32] Senku
    We have the most heat-resistant
    metal in the universe...
[11:36] Senku
    A tungsten filament!
[11:46] Senku
    Now, we have everything we need.
SIGN    Ramen
[11:51] Chrome
    We're on our final sprint
    to making cell phones!
[11:53] Kaseki
    Let's get it done one step at a time.
[11:56] Kaseki
    Time to build the cell phone's
    heart, the vacuum tube.
[12:00] Senku
    There's some slightly complicated
    glasswork we need done to finish that.
[12:05] Senku
    I don't know if even you can
    handle it, Old Man Kaseki.
[12:10] Kaseki
    Oh, please.
[12:11] Kaseki
    I made this ridiculously challenging,
    twisty thing before.
[12:16] Kaseki
    It'll take more than that to scare me.
[12:18] Kaseki
    Here, show me the blueprint.
SIGN    "Hickman Pump"
[12:24] Senku
    It's called a Hickman pump.
[12:27] Senku
    Its vacuum action is off the charts!
[12:29] Senku
    A level ten billion vacuum pump!
[12:31] Gen
    You sound like a vacuum cleaner commercial.
[12:34] Senku
    Vacuum tubes are made by
    removing as much air as possible.
[12:38] Senku
    The prototype we built before was a
    simple level-one pump for light bulbs.
[12:44] Senku
    It won't give us enough power.
SIGN    Air
SIGN    Air
[12:46] Kaseki
    Where do I even begin?
[12:49] Kaseki
    Is this even humanly possible?
[12:53] Gen
    In our age, only the super talented
    craftsmen built Hickman pumps.
[13:00] Gen
    Then again, it was a different age,
    so don't feel too bad, Kaseki-chan.
[13:05] Gen
    It'll never work.
[13:07] Chrome
    Is that true?
[13:08] Senku
    Yeah.
[13:09] Senku
    It's true, but why would
    a mentalist know that?
[13:12] Senku
    He's just talking out of his
    ass to get Kaseki fired up.
[13:21] Kaseki
    I'm fine.
[13:23] Kaseki
    I don't need your mental care.
[13:25] Kaseki
    It's the complicated stuff that
    gets me fired up, anyway.
[13:29] Kaseki
    In exchange, though...
[13:32] Kaseki
    I want to do that thing you
    did with Chrome the other day.
[13:39] Kaseki
    Y'know...
[13:40] Kaseki
    as maker buddies.
[13:47] Kaseki
    All right!
[13:48] Senku
    You can handle the vacuum tube, Kaseki.
[13:53] Kaseki
    Gotcha!
[13:59] Ginro
    Hey, hey, Senku...
[14:01] Ginro
    I just noticed something.
[14:03] Ginro
    Old Man Kaseki's acting like a kid and all,
[14:07] Ginro
    but he's actually trying to
    lighten your burden a little.
[14:11] Senku
    I know that. What are you, stupid?
[14:16] Suika
    S-Senku...
[14:19] Suika
    Is there anything we kids can do?
[14:24] Senku
    Yeah.
[14:25] Senku
    Suika, you guys can handle the wire.
[14:29] Suika
    Yay!
[14:31] Suika
    We're members of the kingdom of science, too.
[14:35] Suika
    We kids are going to make the
    wire without relying on Senku!
[14:40] ---
    Yeah!
[14:43] Senku
    Now the chemistry team
    can focus on making plastic.
[14:49] Chrome
    Yeah!
[14:50] Chrome
    Although I have no idea what
    this whatever-tic stuff is.
[14:53] Gen
    Actually, that's the step on the road map
    that I was the most worried about.
SIGN    Copper
SIGN    Coal
SIGN    Charcoal
SIGN    Beehive
SIGN    Plastic
[14:57] Gen
    Can we even make plastic in this world?
[15:01] Gen
    Isn't it made from, like,
    petroleum or something?
[15:05] Kaseki
    Come, Gen, you're with us.
[15:07] Kaseki
    I'm going to work you to death in
    return for getting me hyped up.
[15:12] Gen
    So mean!
[15:15] Chrome
    Old Man Kaseki's kind of got
    a soft spot for Gen, huh?
[15:23] Senku
    Let's hurry up and start making some plastic.
[15:25] Senku
    First, we simmer some wood and
    boil the liquid that comes out.
[15:29] Senku
    Pour it over some hot copper, and—
[15:31] Chrome
    Wait, wait, wait!
[15:33] Chrome
    I'm completely lost.
[15:35] Chrome
    You heat it to get some liquid,
    heat that again, and heat that again?
[15:39] Chrome
    What are we even doing?
[15:41] Senku
    We're modding the heck out of it,
    adding and removing ingredients.
[15:45] Senku
    Chemistry is all about
    addition and subtraction.
[15:49] Senku
    We did some addition and subtraction,
    and now we have formalin.
[15:52] Senku
    It's the stuff you use to preserve corpses.
[15:54] Chrome
    The smell!
[15:55] Chrome
    Here we go again with the sketchy chemicals
    having to do with corpses and stuff!
[15:59] Senku
    Good.
[16:00] Senku
    Now we just need a ton of coal ash.
[16:03] Senku
    Coal ash plus sodium hydroxide
    plus formaline makes
[16:07] Senku
    humanity's first synthetic plastic, bakelite.
[16:11] Chrome
    R-Right.
[16:13] Chrome
    So we just need to burn a
    crazy amount of coal, right?
[16:19] Suika
    My hands are numb from cold.
[16:21] Suika
    We aren't getting much work done.
[16:23] Grandpa
    What a harsh winter this is.
[16:26] Grandma
    I hope no one dies from the cold this year.
[16:34] Kinro
    Coal?
[16:35] Senku
    Yeah.
[16:35] Senku
    We need a stupid amount of it.
[16:38] Senku
    This is just the job for you guys.
[16:40] Kinro
    Hey, Ginro.
[16:42] Kinro
    Where to?
[16:43] Ginro
    Oh, you know, I have to train, too.
[16:47] Ginro
    And I already work as a guard
    protecting the village,
[16:49] Ginro
    so I think I'll pass.
[16:51] Kinro
    What are you talking about?
[16:53] Kinro
    The village elder Senku's word is law.
[17:00] Ginro
    This is totally going to
    be one of those hard jobs!
[17:02] Kinro
    Rules are rules.
[17:18] Suika
    It's so warm in this house.
[17:21] Grandma
    Let's make a warm meal
    for everyone to eat.
[17:25] Grandpa
    We can get our work done a lot faster now.
[17:31] Senku
    We're only after the ashes from the coals.
[17:35] Senku
    If you want to sit by the
    fire, suit yourselves.
[17:42] Kokuyo
    This is impressive.
[17:46] Kokuyo
    What you're making is totally unrelated,
[17:51] Kokuyo
    and yet the village becomes
    more and more enriched.
[17:56] Senku
    Yeah.
[17:57] Senku
    That's the way science is.
[18:15] Kokuyo
    Senku, my decision to grant you
    the throne wasn't in error.
[18:24] Gen
    Huh? Zinc-carbon batteries?
[18:26] Gen
    Are we using batteries to
    finish the vacuum tubes?
[18:30] Suika
    The build instructions
    and materials are there.
[18:33] Suika
    We'll use the manganese
    we got in the caves.
[18:36] Gen
    So you want me to make them, right?
[18:48] Gen
    Zinc for seaweed.
[18:49] Gen
    Manganese rice balls.
[18:51] Gen
    Coal in the middle.
[18:53] Gen
    Look at that, a zinc-carbon battery.
[18:55] Gen
    Look at that, a zinc-carbon battery.
[18:57] Gen
    Huh?
[18:58] Gen
    It's already done.
[19:00] Gen
    It wasn't that brutal!
[19:04] Gen
    Manganese rice balls.
[19:06] Gen
    Tons of manganese.
[19:07] Gen
    Manganese rice balls.
[19:09] Gen
    Lots of manganese.
[19:11] Gen
    Manganese rice balls.
[19:13] Gen
    Tons of manganese.
[19:15] Senku
    We need 800 of those.
[19:16] Gen
    What?! Eight hundred?!
[19:20] Gen
    This is brutal.
[19:22] Ruri
    I'll help, of course.
[19:26] Kohaku
    Here's the wine you asked for.
[19:28] Kohaku
    Are you holding a banquet or something?
[19:30] Senku
    No, we're making microphones,
    the cell phone's vocal cord.
[19:34] Chrome
    With wine?
[19:35] Senku
    Yeah.
[19:37] Senku
    Actually, we're using the pink
    grains stuck on the lid here.
[19:42] Senku
    Then we mix some cooked seaweed in hot water.
[19:46] Senku
    That's it.
[19:48] Kohaku
    Which part of this is the "microphone" thing?
[19:51] Chrome
    Also, what are these shiny rocks?
[19:54] Senku
    They're called Rochelle salts.
[19:56] Senku
    They turn sound into electricity.
[19:58] Senku
    Tack this onto something light,
