 Ruri Tanigawa : I-I got it! |
(0:00:15.51) |
|
Ruri Tanigawa : Nagi-san! Can you grab a vial?! |
(0:00:16.53) |
|
Ruri Tanigawa : Finally... a real sapphire... |
(0:00:22.44) |
|
Ruri Tanigawa : This thing's tiny! |
(0:00:26.33) |
|
Ruri Tanigawa : I still say it's too small. |
(0:01:58.98) |
 Nagi Arato : Of course it's small, it's from river sand. |
(0:02:00.93) |
|
Nagi Arato : But see how clear and beautiful it is? |
(0:02:04.22) |
|
Nagi Arato : Size aside, it's good quality. |
(0:02:06.61) |
|
Ruri Tanigawa : You're right! After all, a gem is a gem! |
(0:02:08.47) |
|
Ruri Tanigawa : But man, this method is rough. |
(0:02:12.84) |
Ruri Tanigawa : My eyes are so tired,
and my shoulders feel tense. |
(0:02:14.66) |
|
Ruri Tanigawa : But we'll find tons, right? |
(0:02:18.45) |
|
Nagi Arato : Actually, they're pretty hard to find. |
(0:02:20.81) |
Nagi Arato : This specimen is the
only one I've found so far. |
(0:02:23.08) |
Ruri Tanigawa : All this hard work just
to find one tiny grain?! |
(0:02:25.38) |
|
Nagi Arato : Is that a problem? |
(0:02:30.22) |
|
Ruri Tanigawa : I got my hopes up when you said sapphire, |
(0:02:31.85) |
|
Ruri Tanigawa : but as someone that prefers the good
stuff, |
(0:02:35.00) |
Ruri Tanigawa : all this meticulous work
for tiny grains feels silly. |
(0:02:37.15) |
Ruri Tanigawa : It's for people who can't be bothered
to search the mountains. |
(0:02:39.74) |
Ruri Tanigawa : Oh well, now that I've got
this one, I'm satisfied. |
(0:02:44.44) |
|
Nagi Arato : I can't give you that. |
(0:02:48.24) |
|
Nagi Arato : It cost me a lot of work to find it. |
(0:02:50.03) |
|
Ruri Tanigawa : Don't be stingy! |
(0:02:52.03) |
|
Nagi Arato : You still want it after all that complaining? |
(0:02:53.61) |
|
Ruri Tanigawa : Where did you find that, anyway? |
(0:02:57.16) |
Nagi Arato : You know that large bridge
on the way to the university? |
(0:02:59.35) |
|
Nagi Arato : In the river underneath. |
(0:03:02.67) |
|
Ruri Tanigawa : That's not too far. |
(0:03:03.63) |
|
Nagi Arato : What do you say? |
(0:03:05.37) |
|
Nagi Arato : Wanna give it a shot next week? |
(0:03:06.37) |
|
Ruri Tanigawa : Yup. I want a sapphire, too. |
(0:03:08.34) |
|
Ruri Tanigawa : Even if this tiny scale bores me. |
(0:03:10.54) |
|
Nagi Arato : I'm not forcing you to go, you know. |
(0:03:12.32) |
|
Ruri Tanigawa : I said I'm going! |
(0:03:14.00) |
Ruri Tanigawa : Sucks I'll have to be cooped up
with that microscope. |
(0:03:19.01) |
|
Ruri Tanigawa : I liked the mountain trips more. |
(0:03:21.67) |
Ruri Tanigawa : That was go big or go home.
This is hardly as exciting. |
(0:03:23.35) |
|
Ruri Tanigawa : Trapped in a tiny room, looking at a tiny dish. |
(0:03:27.73) |
|
Nagi Arato : It's not tiny at all. |
(0:03:31.26) |
|
Ruri Tanigawa : You don't think so? |
(0:03:32.78) |
Nagi Arato : It may be a small sample, but sand
gives us a peek into a vast world. |
(0:03:34.09) |
|
Nagi Arato : You'd be surprised. |
(0:03:39.88) |
|
Ruri Tanigawa : Tada! |
(0:03:47.54) |
|
Ruri Tanigawa : I collected some sand! |
(0:03:49.07) |
Ruri Tanigawa : Let's get to work
and get this thing over with! |
(0:03:50.66) |
|
Nagi Arato : Wow, you brought a whole bottle's worth? |
(0:03:53.67) |
|
Ruri Tanigawa : Who said I only brought one? |
(0:03:57.88) |
|
Ruri Tanigawa : What are you laughing for?! |
(0:04:03.18) |
|
Nagi Arato : Sorry. |
(0:04:05.18) |
Nagi Arato : I'm just so impressed
with your determination. |
(0:04:06.18) |
|
Nagi Arato : You really went all out. |
(0:04:09.30) |
|
Ruri Tanigawa : Yeah, I did! |
(0:04:11.53) |
|
Ruri Tanigawa : They were heavy to take home, you know! |
(0:04:12.46) |
|
Nagi Arato : Why did you think we'd need this much? |
(0:04:15.34) |
Ruri Tanigawa : 'Cause! I don't wanna
miss out on any sapphires! |
(0:04:18.20) |
Nagi Arato : It'll take well over a year
to search through all this. |
(0:04:21.02) |
|
Ruri Tanigawa : That long?! |
(0:04:24.14) |
|
Nagi Arato : Let me teach you how to collect sand. |
(0:04:26.06) |
|
Nagi Arato : Sapphire has a specific gravity of roughly 4. |
(0:04:29.63) |
Nagi Arato : Remember when we looked
for garnet? Just like that. |
(0:04:32.05) |
|
Ruri Tanigawa : So we should look for sapphire the same way? |
(0:04:34.22) |
|
Nagi Arato : Yup. |
(0:04:36.71) |
Ruri Tanigawa : Umm... So like, behind rocks
or in places with a slower current? |
(0:04:37.72) |
|
Nagi Arato : That's right. |
(0:04:42.19) |
Nagi Arato : You won't need as much sand
if you collect it from the right place. |
(0:04:43.24) |
Nagi Arato : It's good to take initiative,
but with the proper knowledge, |
(0:04:49.67) |
|
Nagi Arato : you'll be able to work more efficiently. |
(0:04:51.98) |
|
Nagi Arato : The easier, the better. Don't you think? |
(0:04:55.65) |
|
Ruri Tanigawa : Yeah! I'm all for taking it easy! |
(0:04:57.61) |
|
Nagi Arato : All right, let's head back. |
(0:05:00.47) |
|
Ruri Tanigawa : There's sapphire somewhere in here? |
(0:05:04.91) |
|
Ruri Tanigawa : Nothing about this screams ＂vast world＂ to me. |
(0:05:08.72) |
Nagi Arato : Give it a light shake so
the grains don't overlap. |
(0:05:16.80) |
|
Nagi Arato : That'll spread out the sand evenly. |
(0:05:19.05) |
Nagi Arato : Start from the edge of the Petri dish
and move it at a uniform pace. |
(0:05:25.77) |
|
Ruri Tanigawa : Okay. |
(0:05:28.89) |
|
Nagi Arato : Let me know when you find someth— |
(0:05:29.89) |
|
Ruri Tanigawa : It's sapphire! |
(0:05:31.37) |
|
Nagi Arato : That's a different color and crystal shape. |
(0:05:34.20) |
|
Nagi Arato : This is a quartz fragment. |
(0:05:36.23) |
|
Ruri Tanigawa : A quartz? |
(0:05:38.42) |
|
Nagi Arato : Take a look. |
(0:05:39.86) |
Nagi Arato : See that black octahedral crystal?
That's magnetite. |
(0:05:43.45) |
|
Ruri Tanigawa : You mean that magnetic rock? |
(0:05:46.87) |
|
Ruri Tanigawa : So sand isn't really just sand? |
(0:05:48.99) |
|
Nagi Arato : Of course not. |
(0:05:51.05) |
|
Nagi Arato : Try finding ore besides sapphire, too. |
(0:05:52.20) |
|
Nagi Arato : Oh, that looks like... |
(0:05:54.42) |
|
Ruri Tanigawa : Okay, my turn! My turn! |
(0:05:55.87) |
|
Ruri Tanigawa : I can't do
this anymore! |
(0:06:03.84) |
|
Nagi Arato : I told you, you won't find much sapphire. |
(0:06:05.45) |
|
Ruri Tanigawa : I know, but it's too hard! |
(0:06:07.55) |
Ruri Tanigawa : Looking at sand through a microscope
all day is just so boring!
|
(0:06:10.73) |
|
Nagi Arato : Come on, just a bit more. |
(0:06:19.61) |
|
Ruri Tanigawa : Can't you cut me some slack? |
(0:06:23.49) |
Nagi Arato : What happened to all
that motivation from earlier? |
(0:06:25.87) |
|
Ruri Tanigawa : Th-That was cause I didn't know any better. |
(0:06:28.63) |
Ruri Tanigawa : Nagi-san, about what you said
the other day... |
(0:06:33.63) |
|
Ruri Tanigawa : I still don't get how this is vast at all. |
(0:06:36.34) |
Ruri Tanigawa : I'd rather look somewhere
that's actually
big. |
(0:06:38.52) |
Nagi Arato : Ruri, where do you think
this sand came from? |
(0:06:44.15) |
|
Ruri Tanigawa : It's from upstream, isn't it? |
(0:06:50.84) |
|
Nagi Arato : That's right. Rocks move. |
(0:06:52.99) |
|
Nagi Arato : This all traveled downstream. |
(0:06:56.02) |
Nagi Arato : Those grains were all once
rocks in the mountains. |
(0:06:58.77) |
Nagi Arato : Something we'd have to
search for on foot otherwise. |
(0:07:02.88) |
Nagi Arato : Those rocks accumulated over decades,
even centuries to become that sand today. |
(0:07:06.94) |
Nagi Arato : No rock is immune to weathering
in that time span. |
(0:07:12.04) |
Nagi Arato : In other words, river sand
theoretically contains |
(0:07:15.83) |
Nagi Arato : every rock that once
belonged in the mountains. |
(0:07:18.18) |
|
Nagi Arato : However much time we spend in the mountains, |
(0:07:22.94) |
Nagi Arato : it's nearly impossible to log
every type of rock there is. |
(0:07:25.01) |
Nagi Arato : But within that Petri dish,
that becomes possible. |
(0:07:27.79) |
|
Ruri Tanigawa : This thing has every rock from the mountains? |
(0:07:32.72) |
|
Nagi Arato : Studying river sand isn't a last resort. |
(0:07:36.69) |
|
Nagi Arato : What seems like just a small handful |
(0:07:39.64) |
Nagi Arato : is actually a vast world
of an unimaginable scale. |
(0:07:41.40) |
|
Nagi Arato : Each grain of sand is proof of its own locality. |
(0:07:45.71) |
|
Nagi Arato : One grain is all it takes. |
(0:07:49.21) |
Nagi Arato : Find it, and it'll become the key
to locating that ore's true site. |
(0:07:50.70) |
|
Ruri Tanigawa : Okay. |
(0:08:03.98) |
|
Ruri Tanigawa : This one's a quartz crystal. |
(0:08:11.66) |
|
Ruri Tanigawa : And this gold one must be... pyrite? |
(0:08:13.39) |
|
Ruri Tanigawa : We saw them both in the mountains. |
(0:08:16.33) |
|
Ruri Tanigawa : You think that's where this grain is from? |
(0:08:18.47) |
|
Nagi Arato : Hmm... It's certainly possible. |
(0:08:20.78) |
|
Nagi Arato : Both were further upstream, so that checks out. |
(0:08:24.01) |
Ruri Tanigawa : So right now, I'm looking at
two mountains at once? |
(0:08:29.45) |
|
Ruri Tanigawa : They were so different. |
(0:08:34.85) |
|
Ruri Tanigawa : That place, and... |
(0:08:36.41) |
|
Ruri Tanigawa : that other place. |
(0:08:37.62) |
|
Ruri Tanigawa : It makes sense now. |
(0:08:41.80) |
|
Ruri Tanigawa : This world... |
(0:08:43.25) |
|
Ruri Tanigawa : What we see in the study of sands |
(0:08:58.78) |
|
Ruri Tanigawa : is much bigger than I thought. |
(0:09:01.19) |
Nagi Arato : It may be a small specimen,
but it has immense value. |
(0:09:07.03) |
|
Ruri Tanigawa : Yup! |
(0:09:10.39) |
|
Ruri Tanigawa : You're right! |
(0:09:11.23) |
Ruri Tanigawa : We don't have time to look
for small fragments like this. |
(0:09:12.25) |
Ruri Tanigawa : We've gotta narrow down its true source
and find some giant sapphires. |
(0:09:14.54) |
|
Ruri Tanigawa : Let's go and search the mountains! |
(0:09:17.51) |
|
Nagi Arato : Not quite yet. We'll study sands some more. |
(0:09:19.31) |
|
Ruri Tanigawa : What? Why? |
(0:09:22.29) |
|
Ruri Tanigawa : We've got our evidence right here! |
(0:09:24.08) |
|
Nagi Arato : Then which mountain do you suggest? |
(0:09:26.08) |
|
Ruri Tanigawa : Well, duh! |
(0:09:27.83) |
|
Ruri Tanigawa : Every mountain... until one day... maybe...? |
(0:09:28.80) |
|
Ruri Tanigawa : Actually, that sounds super hard. |
(0:09:34.60) |
|
Nagi Arato : We'd have to fully cover the entire area. |
(0:09:37.67) |
|
Nagi Arato : It's much harder than typical hiking. |
(0:09:40.11) |
|
Ruri Tanigawa : S-So more river sand? |
(0:09:42.04) |
|
Ruri Tanigawa : Feels like a detour, if you ask me. |
(0:09:44.14) |
Nagi Arato : When studying river sand, we want
to identify the sapphire's source site |
(0:09:46.95) |
|
Nagi Arato : by tracing the river upstream. |
(0:09:50.84) |
Nagi Arato : First, we'll head upstream while
confirming the presence of specimens. |
(0:09:52.86) |
|
Nagi Arato : At each branch point, we'll search both sides. |
(0:09:56.48) |
Nagi Arato : Once we hit a point where we can't
find any more sapphire upstream, |
(0:09:59.20) |
Nagi Arato : that gives us the clues we need
to predict its actual source. |
(0:10:03.45) |
Nagi Arato : That way, we can narrow
down the area we search on foot. |
(0:10:06.98) |
Nagi Arato : Plus, this method helps us collect
sapphire as we look for its source. |
(0:10:10.60) |
|
Nagi Arato : Collect, observe, and verify. |
(0:10:16.15) |
|
Nagi Arato : It's a cycle of legitimate research. |
(0:10:18.99) |
|
Nagi Arato : What we call a scientific approach. |
(0:10:20.50) |
|
Ruri Tanigawa : So we have a better shot with river sand? |
(0:10:24.24) |
Nagi Arato : It's an evidence-based method
that leads to fewer mistakes. |
(0:10:27.23) |
|
Nagi Arato : I suggest we stick with river sand. |
(0:10:30.53) |
|
Ruri Tanigawa : Okay! I'm on board. |
(0:10:33.10) |
Ruri Tanigawa : Still, it sucks that I'll be looking
through microscopes all day. |
(0:10:37.07) |
Nagi Arato : What may seem like a detour
is actually a shortcut. |
(0:10:41.45) |
Nagi Arato : It's less work overall.
Not that it's easy, of course. |
(0:10:44.83) |
|
Ruri Tanigawa : Not many people can stay sane doing this. |
(0:10:48.61) |
|
Nagi Arato : Well, we did find some sapphire. |
(0:10:51.70) |
Nagi Arato : We can end here if you want,
but there's a chance |
(0:10:53.67) |
Nagi Arato : we'll find bigger, prettier
sapphires if we keep looking. |
(0:10:56.34) |
|
Nagi Arato : Now that we have this, it's up to you. |
(0:10:59.82) |
|
Ruri Tanigawa : No way I'm quitting now! |
(0:11:07.02) |
|
Ruri Tanigawa : I can look through microscopes all day! |
(0:11:08.91) |
|
Ruri Tanigawa : There's sapphire still out there. |
(0:11:11.57) |
|
Ruri Tanigawa : I swear I'll find its real source! |
(0:11:13.58) |
|
Ruri Tanigawa : Can I quit already? |
(0:11:28.25) |
Nagi Arato : What? You just said you
were getting the hang of it. |
(0:11:30.38) |
|
Ruri Tanigawa : I thought so... |
(0:11:34.04) |
|
Ruri Tanigawa : But now that I'm at a branch point, |
(0:11:36.85) |
|
Ruri Tanigawa : and I've already found sapphire on one side, |
(0:11:39.40) |
|
Ruri Tanigawa : having to search the other side just... |
(0:11:41.72) |
Ruri Tanigawa : It sucks so bad having to
make sure I don't
find sapphire. |
(0:11:44.78) |
|
Ruri Tanigawa : I didn't think it'd be so grueling! |
(0:11:47.86) |
|
Ruri Tanigawa : Knowing there's sapphire on the first side |
(0:11:50.28) |
|
Ruri Tanigawa : makes it that much more pointless! |
(0:11:52.55) |
Ruri Tanigawa : Can't we just search upstream
where we do
find sapphire? |
(0:11:54.55) |
|
Nagi Arato : Doesn't work that way. |
(0:11:57.67) |
Nagi Arato : It's vital that we confirm
where there's no sapphire. |
(0:11:59.15) |
Nagi Arato : I need you to look through
everything as planned. |
(0:12:01.85) |
|
Ruri Tanigawa : Come on! The easier, the better, right? |
(0:12:06.35) |
|
Ruri Tanigawa : It's good enough to search one side. |
(0:12:08.53) |
Ruri Tanigawa : We've looked this much
and haven't found it yet anyways. |
(0:12:10.71) |
|
Ruri Tanigawa : Please? |
(0:12:14.31) |
|
Nagi Arato : Nope. |
(0:12:19.10) |
|
Ruri Tanigawa : Done! No sapphire! |
(0:12:34.07) |
|
Nagi Arato : Good work. |
(0:12:37.37) |
|
Ruri Tanigawa : Turns out I was right all along! |
(0:12:38.58) |
|
Ruri Tanigawa : I told you it was a waste of time! |
(0:12:40.26) |
|
Nagi Arato : Nope. Even with the same results, |
(0:12:41.99) |
Nagi Arato : it makes a world of a difference
that we checked. |
(0:12:44.18) |
Ruri Tanigawa : Easy for you to say.
You didn't have to do this work. |
(0:12:46.98) |
Nagi Arato : You were the one who decided
to look for sapphire, Ruri. |
(0:12:49.68) |
Ruri Tanigawa : So mean!
I'm just a friend
who needed some help! |
(0:12:52.79) |
|
Nagi Arato : I've got my own research to focus on. |
(0:12:56.45) |
|
Nagi Arato : But I'm wishing you luck. |
(0:12:59.14) |
 Aoi Kasamaru : 'Sup, Ruri. Wanna stop
somewhere on the way ho— |
(0:13:05.64) |
|
Aoi Kasamaru : What's got you in a rush? |
(0:13:08.81) |
|
Ruri Tanigawa : Prep for tomorrow! |
(0:13:10.34) |
|
Aoi Kasamaru : Huh? What's tomorrow? |
(0:13:11.53) |
|
Ruri Tanigawa : I'm going to the river! |
(0:13:13.18) |
|
Aoi Kasamaru : River? What for? |
(0:13:14.31) |
|
Ruri Tanigawa : See ya! |
(0:13:16.20) |
|
Aoi Kasamaru : H-Hey! |
(0:13:17.17) |
|
Aoi Kasamaru : She's gotten real flaky recently. |
(0:13:22.03) |
Ruri Tanigawa : It's only sand! It's only sand!
I can get it by myself! |
(0:13:29.98) |
|
Ruri Tanigawa : This place looks good. Perfect! |
(0:13:36.96) |
|
Ruri Tanigawa : Step one! Narrow, smaller rivers. |
(0:13:40.56) |
Ruri Tanigawa : That black sand must be magnetite.
This should work. |
(0:13:46.59) |
|
Ruri Tanigawa : What next? |
(0:13:49.79) |
|
Ruri Tanigawa : Might as well look in this bigger river, too! |
(0:13:52.34) |
|
Ruri Tanigawa : This is a piece of cake. |
(0:13:57.01) |
|
Ruri Tanigawa : Nothing I can't do myself. |
(0:13:58.46) |
|
Ruri Tanigawa : Huh? |
(0:14:00.88) |
|
Ruri Tanigawa : Where's my loupe? |
(0:14:04.23) |
|
Ruri Tanigawa : Good thing I bought my own. |
(0:14:06.36) |
|
Ruri Tanigawa : A hexagonal sapphire. |
(0:14:10.16) |
|
Ruri Tanigawa : It's the biggest one I've found so far. |
(0:14:11.66) |
|
Ruri Tanigawa : What if this is its source site? |
(0:14:17.54) |
|
Ruri Tanigawa : If this is really it, then... that means... |
(0:14:20.56) |
|
Ruri Tanigawa : No more studying sand! |
(0:14:25.33) |
|
Ruri Tanigawa : Let's do this! |
(0:14:29.86) |
 Youko Imari : And you rushed straight back
and came all the way here? |
(0:14:38.37) |
|
Ruri Tanigawa : 'C-Cause... I found that blue rock... |
(0:14:42.40) |
|
Nagi Arato : Are you talking about this chalky part? |
(0:14:46.13) |
Nagi Arato : Hard to say for sure, but it's most
likely a copper-based mineral. |
(0:14:48.97) |
|
Ruri Tanigawa : Copper?! |
(0:14:53.00) |
Youko Imari : Yeah, that would explain
the bluish-green color. |
(0:14:54.54) |
|
Ruri Tanigawa : It's not sapphire?! |
(0:14:57.71) |
|
Youko Imari : There's no copper in sapphire. |
(0:14:59.35) |
Ruri Tanigawa : But... isn't a blue-green
rock kinda rare? |
(0:15:04.17) |
|
Ruri Tanigawa : It's gotta be, right? Please? |
(0:15:08.24) |
|
Nagi Arato : Ever heard of verdigris? |
(0:15:10.28) |
Nagi Arato : Like you see on bluish-green statues.
It's the same as that. |
(0:15:12.34) |
|
Nagi Arato : There are lots of copper-derived minerals. |
(0:15:17.02) |
|
Nagi Arato : That's another topic worth diving into. |
(0:15:19.18) |
|
Nagi Arato : But sapphire comes first for now. |
(0:15:21.20) |
|
Ruri Tanigawa : So it was all a waste? |
(0:15:23.16) |
Nagi Arato : You got a bit ahead of yourself
looking for larger sapphires. |
(0:15:26.07) |
|
Nagi Arato : Let's not be too quick to take shortcuts. |
(0:15:29.60) |
|
Youko Imari : You okay? |
(0:15:40.25) |
|
Youko Imari : I'm here to listen if you need to vent. |
(0:15:41.63) |
|
Ruri Tanigawa : It's Nagi-san. |
(0:15:43.48) |
Ruri Tanigawa : She was the one telling me
about how to make things easier, |
(0:15:45.09) |
Ruri Tanigawa : but when I try to do the same thing,
she won't let me. |
(0:15:48.62) |
Ruri Tanigawa : I bet she just doesn't want me
doing my own thing. |
(0:15:51.97) |
|
Ruri Tanigawa : She's just being a meanie! |
(0:15:54.32) |
|
Youko Imari : I doubt that Arato-senpai would do that. |
(0:15:57.07) |
Ruri Tanigawa : Hmph, you wouldn't get it.
You're too hardworking. |
(0:15:59.77) |
Ruri Tanigawa : I just don't get how
I'm different from Nagi-san. |
(0:16:04.57) |
|
Ruri Tanigawa : We're both just looking for shortcuts. |
(0:16:07.03) |
|
Youko Imari : Let's see... |
(0:16:09.61) |
Youko Imari : While Arato-senpai wants
to avoid unnecessary work, |
(0:16:11.05) |
|
Youko Imari : you might be leaving out important steps. |
(0:16:14.13) |
|
Youko Imari : If Senpai's approach is about work efficiency, |
(0:16:16.59) |
Youko Imari : Ruri-chan, yours is about...
cutting corners? |
(0:16:18.42) |
|
Ruri Tanigawa : Fine, I get it. |
(0:16:21.68) |
|
Ruri Tanigawa : Nagi-san's the smart one. |
(0:16:23.00) |
|
Ruri Tanigawa : I'm too dumb to be efficient like her. |
(0:16:24.97) |
|
Youko Imari : Look at it from another viewpoint. |
(0:16:27.60) |
|
Youko Imari : That's the important part. |
(0:16:29.51) |
|
Youko Imari : It's not about how smart you are. |
(0:16:31.72) |
|
Youko Imari : If you want to study sand more efficiently, |
(0:16:35.10) |
Youko Imari : why don't you try
to better understand it first? |
(0:16:37.56) |
|
Ruri Tanigawa : Understand sand? |
(0:16:40.77) |
|
Youko Imari : Don't ask me. |
(0:16:43.94) |
|
Youko Imari : My research doesn't involve sand anyway. |
(0:16:45.57) |
|
Ruri Tanigawa : What?! I thought you were giving me advice! |
(0:16:47.75) |
|
Ruri Tanigawa : Understand... sand...? |
(0:16:53.34) |
|
Ruri Tanigawa : Ores I've learned so far are |
(0:16:56.33) |
|
Ruri Tanigawa : quartz, pyrite, magnetite, and sapphire. |
(0:16:58.23) |
|
Ruri Tanigawa : Oh, and maybe placer gold. |
(0:17:02.20) |
|
Ruri Tanigawa : Other than that, it's a total mystery. |
(0:17:04.65) |
Ruri Tanigawa : Should I change how much
sand I observe at once? |
(0:17:08.27) |
|
Ruri Tanigawa : Do I do more or less? |
(0:17:10.90) |
|
Ruri Tanigawa : No, I'll have to look through it all anyways. |
(0:17:12.47) |
|
Ruri Tanigawa : Unless I find a way to cut down this sand, |
(0:17:15.58) |
|
Ruri Tanigawa : there are no shortcuts. |
(0:17:18.11) |
|
Youko Imari : Oh no, something stuck to it. |
(0:17:25.91) |
|
Ruri Tanigawa : Imari-san! |
(0:17:27.90) |
|
Ruri Tanigawa : Can I borrow that?! |
(0:17:28.90) |
|
Ruri Tanigawa : I did it. |
(0:17:38.92) |
|
Ruri Tanigawa : I cut down the amount of sand! |
(0:17:40.52) |
|
Youko Imari : Way to go! |
(0:17:42.55) |
|
Ruri Tanigawa : Remember what you said about sand? |
(0:17:43.72) |
Ruri Tanigawa : I thought about what ore makes up
sand, and came up with... |
(0:17:45.58) |
|
Ruri Tanigawa : Uh-oh, it's stuck to the magnet. |
(0:17:48.89) |
|
Youko Imari : Hang on. |
(0:17:51.41) |
|
Youko Imari : All good to go! |
(0:17:53.84) |
|
Ruri Tanigawa : I cut down this much! |
(0:17:58.93) |
|
Youko Imari : See, this is work efficiency! |
(0:18:01.30) |
|
Ruri Tanigawa : So this is work efficiency! |
(0:18:03.35) |
|
Nagi Arato : You two up to something? |
(0:18:11.86) |
|
Ruri Tanigawa : Look at this! |
(0:18:13.11) |
|
Ruri Tanigawa : You know how magnetite sticks to magnets? |
(0:18:14.77) |
Ruri Tanigawa : I thought that might help cut down
the amount of sand. |
(0:18:17.03) |
|
Ruri Tanigawa : That it might be... a good shortcut... |
(0:18:20.69) |
|
Nagi Arato : Ruri, you thought of that? |
(0:18:25.00) |
|
Ruri Tanigawa : Yeah. |
(0:18:26.85) |
|
Nagi Arato : That's a great idea. Great thinking. |
(0:18:28.71) |
|
Ruri Tanigawa : N-Nah! It didn't cut down too
much. |
(0:18:32.88) |
|
Ruri Tanigawa : It's not that
big of a deal. |
(0:18:35.75) |
|
Nagi Arato : No, that adds up and makes a huge difference. |
(0:18:37.46) |
|
Nagi Arato : Let's use this method from now on. |
(0:18:40.47) |
|
Youko Imari : Work efficiency! |
(0:18:44.48) |
|
Ruri Tanigawa : Work efficiency! |
(0:18:45.62) |
|
Ruri Tanigawa : I think I'll call it a day. |
(0:18:56.11) |
|
Nagi Arato : Hang tight, I'll take you home. |
(0:18:58.45) |
|
Ruri Tanigawa : Okay. |
(0:19:01.33) |
|
Ruri Tanigawa : How's your research going, Imari-san? |
(0:19:05.74) |
|
Youko Imari : I've made some progress. |
(0:19:07.74) |
|
Youko Imari : Look, this is my new sample. |
(0:19:08.97) |
|
Ruri Tanigawa : Wow... so this clear stuff is all fluorite? |
(0:19:11.82) |
|
Youko Imari : Actually, this is a special specimen. |
(0:19:15.75) |
|
Youko Imari : Take a look here. |
(0:19:18.26) |
|
Youko Imari : See how the fluorite's melted on top? |
(0:19:19.99) |
|
Ruri Tanigawa : Hmm? |
(0:19:22.61) |
|
Youko Imari : The groundwater likely played a role in that. |
(0:19:23.64) |
|
Youko Imari : But look at the smaller one next to it. |
(0:19:26.12) |
|
Ruri Tanigawa : This one hasn't melted. |
(0:19:29.24) |
|
Youko Imari : This contradiction is what makes it special. |
(0:19:30.48) |
|
Youko Imari : It could help us learn more about that mine. |
(0:19:32.87) |
Youko Imari : If they're both fluorite,
they should melt the same way. |
(0:19:35.56) |
|
Youko Imari : Which can only mean...? |
(0:19:39.17) |
|
Ruri Tanigawa : The smaller one... isn't fluorite? |
(0:19:41.06) |
|
Youko Imari : Bingo! |
(0:19:43.66) |
Youko Imari : I think it's scheelite, an ore with
a higher melting point than fluorite. |
(0:19:45.12) |
Youko Imari : Scheelite contains tungsten,
a rare metal that was |
(0:19:49.58) |
Youko Imari : really important in the past
to create artillery shells and steel. |
(0:19:53.66) |
Youko Imari : I'm hoping this information
helps us find historical records. |
(0:19:57.98) |
|
Youko Imari : But it's still a long road ahead. |
(0:20:02.89) |
|
Ruri Tanigawa : Yeah? Looks like you're having fun, though. |
(0:20:05.22) |
|
Youko Imari : I am having fun! |
(0:20:08.10) |
Youko Imari : I couldn't tell which minerals
were which before. |
(0:20:09.97) |
Youko Imari : But I've studied,
learned new things, and now... |
(0:20:14.39) |
Youko Imari : Bit by bit, there are more
minerals that I can identify. |
(0:20:18.39) |
|
Ruri Tanigawa : Sounds like your research is going well. |
(0:20:22.78) |
Youko Imari : Yup! I might have sounded
preachy a second ago, |
(0:20:24.68) |
Youko Imari : but it was a lesson I had to learn
for myself for my research. |
(0:20:28.27) |
Youko Imari : Just like you have to understand language
before you can read books, |
(0:20:32.98) |
Youko Imari : I had to understand rocks before I could
learn about their nature and history. |
(0:20:38.64) |
Youko Imari : Once I learned to read rocks better,
I could follow their context. |
(0:20:46.48) |
Youko Imari : I think that's what it means
to see things for yourself. |
(0:20:51.68) |
|
Ruri Tanigawa : Yeah... |
(0:21:00.26) |
|
Nagi Arato : Sorry about the wait. Ready to go? |
(0:21:03.24) |
|
Ruri Tanigawa : Actually, Nagi-san... |
(0:21:05.27) |
|
Ruri Tanigawa : Can I stay a bit longer? |
(0:21:07.32) |
|
Aoi Kasamaru : Heading to the river again? |
(0:21:16.39) |
|
Ruri Tanigawa : Yup! |
(0:21:18.22) |
|
Youko Imari : Ruri-chan, you're basically a pro at that now! |
(0:21:57.83) |
|
Ruri Tanigawa : Think so? |
(0:22:03.11) |
