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
@qn I might be wrong but slight correction: instead of Voltaic/Galvanic cell it should be electrolytic cell In a voltaic cell, you convert chemical energy into electrical and therefore don't need a power source.
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.
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
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
Man I would absolutely follow along if I had access to this guy's huge collection of equipment. Imagine showing them off "And THIS is my chocolate knife (it is also naturally antibacterial due to silver infusion). And THIS is my bread knife. This one is made from smoke, and this one is made from milk..."
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
9. The fact that this caused me to eat a bowl of chocolate ice cream while watching it despite me remembering on the very last bite that I am lactose intolerant
Dude chose the best time to start, too He just exploited the “so satisfying” trend to show himself making knives out of ridiculous stuff, and now he’s here and I love it
beginning of the video: "nothing is clear" middle of the video: "still not clear" almost the end of the video: "you begin to understand" end of video: "admire his genius"
“How was he killed?” “Sweet and clean…” “That sentence was a lil sus… was that a confession?” “Oh anti-bacterial chocolate knuckle duster knife how I miss you so”
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.
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! 💕
He just infused pure silver to chocolate and melt it into a knife, silver is used to filter water sometimes, now having silver in the chocolate knife, it filters the knife from bacteria.
@@pika3207 we can but you don't want a lot of silver in your body, we have 0 usage for it, and it can cause a condition that makes your skin blue, not good.
His annual income is 12 million yen before he even started RU-vid, i don't see any reason to quit job entirely when those will get him all the fancy home machines he's using in the vids
@@nadeeyaaridza1684 in his "The Fake Meat, Glue Meat, Injection Meat secret" video he answered questions about his background and showed his tax slips in that as well
If you can't give someone homemade desserts in fear of contamination, just make antimicrobial chocolate from scratch by suspending silver ions in agar and mixing it in. Can't believe I didn't think of that before.
@@randomassortmentofthings It can like almost everything but you're probably be fine eating this knive tho it will taste very bitter, because he didn't add sugar
Forging, yes. Smelting, no. Silver clay is already pure silver in suspension. You mold it to the shape you want, then fire it in a kiln to burn away the suspension materials, leaving behind pure metal. There's gold clay as well, for the same purpose.
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.
cant distill anything aggressive with this setup though. chemist's need to distill acid's for example which would eat the metal and ruin the final distillate. glass usually does not do this.
@Kray I used a cool and niche little literary technique called "exaggeration for comedic effect" in my original comment, the joke being that sometimes chemistry equipment in general can be expensive. Hope that clears it up for you :)
Except most people, like me, are still fully confused with no clue what's happening or for what reason. If you're like, a chemist or something you might know.
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.
I think that's an alpha-type Stirling engine, rather than a thermopile! Sorry, this is a little pedantic I know, but thermopiles are constructed very differently so I thought I'd mention for folks who want to research this process. Thermopiles are actually really inefficient at that scale, while Stirling engines of any type (but especially alpha-type) are very efficient at small scales - to my knowledge, they're the most efficient small-scale heat-driven engine! For anyone who cares, the reason he was using glass beakers for everything up til he exposed the Ag1+ solution to UV light is because UVB and UVC can't pass through glass. You need to either use quartz, which is really expensive, or plastics. Not all plastics are UV-transmissive but many are! I can try to answer questions about why he did the steps he did lol if anyone cares.
I haven’t finished the video yet but what I saw looked more like a steam engine to me since the pistons were the same size, though I did see no water input or exhaust, so maybe it is a Stirling engine. They’re pretty cool, Lindybeige has some great videos about them.
@@Abigail-hu5wf Why did he dissolve the silver ions (?) in the agar and then combined the agar with the chocolate, instead of using the Ag+ water solution he had made before? Does the agar really contribute much to the integrity of the knife?
Can we just acknowledge that how this man’s brain works is one of life’s greatest mysteries. He has turned chemistry into an art form. If he ever decides to turn to the dark side we are doomed as he could probably turn a loaf of bread into a nuclear reactor. Probably one of the few videos where there is never the comment “I could do that!”
Nah it's a bit overkill just to understand that, but man, still need heaps of knowlege frow a wide variety of fields. In short: still have to be at least a bit smart :) Every one can understand it without PhD if you have interest in these fields.
