This year's Valentine chocolate is finally complete ※これはバレンタインチョコです

It's good to see you back

最初から全部見てて、どこがどう繋がるの！？！？と思ったら、ちゃんと抗菌滅菌除菌について詳しく実験して見せてくれたのがわかって感動した....... 天才はかんがえることが違う。 観点培養始めた時は何が起きるかと思ったけど、目で見てちゃんと分かるのほんと助かる、、

this guy is the definition of the saying "if you want to make a pie from scratch, first you have to make the universe" but for knives

Man combines chemistry, biology, physics, insanity, epicness and humour all into one video which he films in his kitchen.

he did all that work to show us that silver kills bacteria. what a bloody legend

The real reason we haven't seen a new Kiwami JP video in so long is because he's crafting his finest knife yet. Collecting the materials is just taking a while

更新無いせいで捕まったかって言うコメがちょこちょこあるの草

This is a tough one but I tried my best: Silver clay: source for silver nanoparticles - Burn off all additives to get purer silver metal in chunks, also made into a bar shape Weird contraption with the wheel that he heated up on one side: I believe that's a Stirling engine, google it for more details - Used as power source for a voltaic/galvanic cell Voltaic cell: the beaker with the water and the 2 bars of metal -EDIT: this is actually an electrolytic cell, basically the opposite of a voltaic cell - Used to extract ions from the silver bar into whatever liquid it's dunked in Condenser: the big plastic bucket with 2 holes high and low on the sides + the metal tube connecting them - TDS reading = he is showing how tap water is not pure, has tons of stuff in it that's NOT silver - Can use the simple condenser setup to make distilled water - Boil tap water on one side, pure water boils, stuff in it doesn't follow and stay back down - Water vapor goes into the funnel, through the metal tube - Metal tube goes through the ice water bucket, which is cold - Hot vapor + cold temperature = water condenses back into liquid, falls into collecting beaker - Now you have distilled water = pretty pure water Voltaic cell (again): now he is making a proper voltaic cell with 2 chambers - EDIT: electrolytic not voltaic - Same concept as before but now the chamber with silver will be only water + silver ions UV light chamber: he's using UV light to add energy to supercharge the silver ions (photocatalyst) - Make silver ions better at killing bacteria - Color change is probably from excited ions? I'm not sure - EDIT: turns out this is just to decompose the silver compound, basically showing you that this is actually silver he is working with Cooking pan: he has pure, excited silver nanoparticles powder here - He's not using the powder though, he's only doing it to show you that he has silver powder - Weird flex, but very OK Agar: aka jelly; he's suspending the silver ions inside the jelly for easy use Petri plates: used to grow bacteria cultures - Agar + sugar = jelly is food and land for bacteria to grow; bacteria eats a lot, so by using a few sticks of sugar he will not get too much bacteria - Keyboard, door handle, shoe = common places that has bacteria lying around Box + heater: incubation chamber, he's going to grow the bacteria plates in here; temperature is 35 C, toasty - Shows you that he has live bacteria to use for testing - Agar + consomme cube = consomme is stock, this nutritious food will feed any bacteria out there, so he will get a LOT of bacteria, all kinds - Agar + consomme cube + silver jelly: this is to show you that the silver jelly does kill bacteria; if there is enough food but no bacterial growth, it means the silver jelly used sharp knives to shank them and their children in their sleep Chocolate making: literally anything will make be hard if you dry them enough Doll in bathtub: centrifuge - Chocolate melts because it is suspended in natural oil - The centrifuge spins very fast; heavy cocoa sinks to bottom, cocoa oil floats on top - He poured out all the oil, leaving only cocoa powder - He probably stuck a spinning motor rod through the doll's butt, and the leg is the switch Now: add silver jelly to the hard core cocoa powder, and you can shank people without fearing bacteria will kill them before you do. This year's Valentine chocolate is finally complete

作業工程全部 意味や根拠があるんだろうけど、よくわからんまま見てるKZfaqr第1位

I love that he does things specifically not because they are easy but because they are hard. He could buy silver ready to mix into the chocolate, he could link to other sources to prove silver's antibacterial properties or show them more simply, he could use a phone charger to power the reactions, or just buy filters and proper lab equipment to distill. Yet he *CHOOSES* to do the work to show the silver killing bacteria, he chooses to use unique or just different equipment, and shows an actual practical use for the sterling generator combo. The doll shaped centerfuge is impressive.

7ヶ月も経ってるけど きっと彼は大掛かりなものを作っているのだろうなと信じてる

He just added enchantments to a knife

制作過程を見ててもどうして結果に辿り着くのか欠片もわからんがとりあえず、この人がとんでもなく頭が良いという事ととんでもなく不審者であるという事は分かる。

from his interviews ・He makes 12,000,000 Yen a year with his day job. ・He has second job, some kind of venture company and being a KZfaqr is his 3rd job. ・He is a workaholic and works at least 5 hours even on his days off. ・He grew up in a single mother family and only skill his mother taught him was to sharpen knives. ・He is NOT particularly interested in making knives, but he is very interested in different materials he makes knives with. ・When he does something he gets obsessed. He used to think about his work all day even in the bed and couldn't sleep well, so he decided to run after work, so that he will be exhausted and be able to sleep. Then he got obsessed with running and run 3 to 4 hours everyday until he got fatigue fracture on his leg. ・One of his dreams is to make a knife with Artificial diamond.

この人はいつも投稿頻度が少なめで数か月に一本とかだから信じて待ってる

17分かけて銀イオンの凄さを説明して残りの8分で頭のおかしさを説明する動画です

I like how this channel went from sharpening knives to advanced chemistry

いつも「なにやってんだろー」って思いながら見させていただいています。楽しいです。ありがとうございます

おすすめ… 泣かせるなよ… 懐いなもう…

Me: "oh cool another knife" Video: "here's 17 full minutes of actual chemistry work"

"Is this chocolate unhealthy?" "No, but it can hurt you in other ways."

Omg this guy is phenomenal!! I thought the title was insanity but he genuinely combined a bunch of crafts and sciences together and legitimately made an anti-bacterial chocolate knife, like wtf 😂 definitely subscribing, this was fascinating to watch! Love these videos! 💕

急にこの動画がおすすめに流れてきて、復活したんかと思った。 待ってます

i really appreciate that he doesn’t talk and just goes at his craft. I wouldn’t be complaining if he did talk, it’s just that the way he films and does stuff is satisfying

更新のない間本当に警察のお世話になっているんじゃないかと1番心配しているチャンネル

さすがに捕まったのかな……

この動画を見た感想 勉強になる理科の実験だった

こんな時間かけて作ったのを、最後そうする勇気がすごい

銀の抗菌作用を証明してからチョコレート作ってるの草だし、遠心分離のかけ方が不審者すぎる

不審者さん 捕まったんかな 刃物量産したから

I hope you are pursuing a degree in material science. As a chemist and knife nerd you never cease to amaze me with your innovative uses of materials.

主の製作期間が3～4ヶ月程度である事を考慮すると、今年のバレンタインからこのチョコをずっと作っていたことがうかがえる。 お疲れ様です。

This person is like Rule 34 of knives, it's like: if it exists, there is a knife of that

更新ないから捕まったのかなって思ってたんだけど、ちらほら同じこと思ってる人いて安心した(？)

"officer, i was just disinfecting that man"

This man scares me. Hes a real life alchemist and has slowly become more and more self sufficient. Like dude owns a heat powered generator to power his works now

過去一で手順が理解できない圧倒的不審な一振

最近見ないと思ってたらやっぱこれで動画止まってたかあ

食べたら歯抜けるどころか口ん中ズタズタになるわww ところで生きてる？？こんな居なくなって悲しい不審者いねぇよ

The 0.01% of bacteria that survive: "Why am I hearing boss music?"

リカちゃん遠心分離機恐怖でしかないw リカちゃん次はどんなふうに生まれ変わってくれるのか楽しみw

そんなに前と思ってなかったのに最後が７ヵ月も前で震えてます...。（時間が経つ早さに） 新作も観たいですが生存確認だけでもしたいです😭

Simply the fact that this is completely understandable with just a handful of words thrown in makes it genius. The video not only shows what is happening but also why, all in images.

どんどんよくわかんない道具が増えてく中の牛の安心感よ

As soon as I saw the doll's head start to spin, I realized I was watching both a genius and an absolute maniac. Edit: Grammar corrections.

この動画を見て思い出して昔のチョコレート包丁の動画見てたら不審者さんの進化を感じた どれだけ進化しても変わらないきゅうりと水差しが好き

おもちゃの刀の中にセメント詰めて ダンボールしばいてた人とは思えない

I'm incredibly concerned by the fact that he's now designing knives that are clearly not suited for kitchen use.

Therapist: “The doll centrifuge isn’t real, it can’t hurt you” *the doll centrifuge*

The amount of time, effort, and scientific prowess that went into this video is *absolutely insane...*

I laugh so hard when he uses portable drill instead of cranking the grinder wkwk

I can't tell if this man is a professional, or just borderline insane.

4ヶ月投稿なくても納得できる作業量

って、Twitter覗いたら昨日生存報告しとるやんけ！！！ 追記 去年のだった泣いた

不審者さんとうとう職質でも受けたんですか？

遠心分離とか寒天培地とか、やってる事は大学の研究室レベルでもおかしくないのに結局包丁に戻る不思議

Some of my favorite things about these videos (in no particular order) 1. The amount of emotion he can convey even without words or a face 2. Some of the absurd things he owns (what even is that steampunk generator. or the doll centrifuge.) 3. The complex biochemical processes he does even with simple materials (distilling water, making an electrolytic cell) 4. The fact that you already know how the video is going to end (knife), but you are constantly blindsided by the twists and turns taken to get there 5. The soothing, ASMR-like quality of these videos 6. The somehow simulations feral, unhinged quality of these videos 7. The fact that they are presented almost like a how-to despite not being something that anyone else could do or would even want to do 8. Cows

Average american discovering how really chocolate it's made:😮😮😮😯😯😯😲😲😲🤯

1:20「銀粘土」 自分:「……銀粘土?」

Ag＋の抗菌の実験で１ヶ月以上かけてるのに仕上げた包丁茹でるのほんと狂気

I was caught off guard when the doll started spinning like some cursed amusement park ride haha

all fun and games until a hot summers day comes around and ruins your hard work 😂

When the world needed him the most. He disappeared.

I love how these are all framed as tutorials, even though no one in their right mind would follow along.

圧倒的さんが使った物で、一通り理科の実験できそう

中学時代には欠片も理解できなかった内容が高校になって少しは分かるようになって、なにか感動しました👍👍👍

固さに驚くけど、こんなでかさの板チョコ良いなぁ(笑)

この世で唯一リカちゃんを遠心分離機にする不審者 The only suspicious person in the world who uses a doll as a centrifugal separator.

やってることも凄いけど、こんだけ色々やって道具やキッチンが綺麗なの凄いなあ

This is still one of the best channels on KZfaq.

歯が抜けまーす所じゃねぇw😂

I love this man. The dedication to work with burnt chocolate, the vision to infuse silver in to chocolate to take advantage of it's antiseptic properties, the persistence to finish the task, the questionable stance on societal norms/conventions that let's him make that centrifuge! Genius!

This man maxed his Cook, alchemy and blacksmithing skill tree just to make custom assassin weapons

this is the last video on the channel. I hope he's okay what with everything going on in the world lately.

半年以上更新ないなぁ。 遂に捕まった…⁇

化学で習ったことってこういうことだったんだなぁってわかって勉強になる

This knife kills the other 0.01% of bacteria

All the science was really cool But chocolate that is almost a full 40 digits higher hardness than a _frying pan?_ *That's* cool.

手でねりねりしてて「こりゃ大変だ」 とか思ってたら電動ドリルでぐいんぐいんやっててまじで笑った

I always forget this channel exists and then it comes back on my feed like once a year. I always enjoy these.

最近理科の実験とか化学の楽しさが学べてすごく好きです

毎回毎回、素人目からすると レベル高すぎて何やってんのか混乱してくるw

初めてコメントします。 高校生の時、初めて不審者さんの動画を見て衝撃を受けました。これからも動画楽しく見させていただきます！

因みに金や銅でも同様に抗菌作用がありますが、金はそれ自体が高価でそれに加え加工に濃塩酸と濃硝酸を混合した王水を使う必要がありコストが高く、銅は柔らかいものの酸素と結合して酸化銅になると有毒性を発言してしまう事から主に銀が使われています。

“Can we see the murder weapon” “Your honour we have reason to believe the weapon was consumed after committing the crime”

底すらない狂気を見せつけられて、 結局どんなウィルスよりも生きた人間が一番怖いと思った。

あすまのチャクラ刀で草

I love the subtle ways his channel has changed and improved. It’s funny, creative and interesting. There’s not just a cool scientific angle, the knife and video are like a sort of art project.

This dude's videos will always fly over my head because I don't know enough about chemistry to understand what he's doing, but it's always so fascinating watching him turn whatever the hell he wants into a knife.

なぜこの包丁を作ろうと思ったのかが不思議

こんな大作を一瞬で溶かしてしまうなんて、、、

Didn’t this guy turn literally smoke into a knife at one point?

“Mom! Kiwanis is making my doll into a centrifuge again!”

If anyone's curious, silver is actually surprisingly safe to consume. Most other metal has a negative effect (like an iron overdose for example) but silver doesn't really do anything, and you have to eat a ridiculous amount of it to get it to do anything.

Parents:dont eat too much chocolate it make your teeth bad. Also chocolate:

半分以上銀の抗菌作用を示す実験で草(好きです)

the scariest thing is that he doesn't even bother to comment on all the science he is doing.

チョコレート除菌する奴初めて見た

サムネNARUTOのあすまのやつかとおもった
