I've made my own cream soda like this for years. I pour a sheet of caramel, grind it up in a mortar and pestle then mix it with home made vanilla extract and water to from the syrup. From there, just use club soda or stick it in a soda stream. You can also use a brewed method similar to how root beer, birch beer and sarsaparilla were originally made. Make sure to use a low gravity yeast like LA-01 and get bottles with a deep punt if you want substantial carbonation. Regular bottles and jars tend to explode when making soda. Because of the sugar content, you typically just wait for the yeast to kill themselves off with the alcohol they are producing, which is a lot less controlled than dosing with sugar like you would for Champaign or beer.

You just need more tube with a water jacket below it to cool the metal as it is falls. The metal wont get stuck because it contracts when cooling. You would still need to draw the metal down to get wire. But honestly your easiest method would be to make thin flat sheets and cut that into wire.

How do i make a Gold-Sheet? @ScamstinCrew

Before wire drawing dies were invented, gold wire was made by pounding gold into thin sheets, cutting the sheets into narrow strips, and twisting the strips into long spirals. The spirals were then compressed, probably by rolling them between hardwood blocks or smooth stones, to make smooth wire for jewelry. One signature of pre-industrial jewelry is that the wire has a spiral seam that's visible under magnification. Wires like that were probably made just long enough for whatever jewelry project, but if the gold is pure enough, it can be cold-welded by heating it in a flame to burn off surface grease, then pressing it together, so you should be able to make strips of any length by welding them end to end, then convert to wire

the breakage is more caused by surface tension; in the liquid state, the metal atoms are more attracted to other metal atoms and less attracted to air molecules, hence the atoms tend to get pulled more towards the center of the molten metal, forming roughly spherical blobs. This is the same reason water beads up when you pour it.

For your final laminar flow method, I think it might work if done from high enough. In the past, bullets were made in shot towers. There, they dropped bits of molten lead from a high place. Due to turbulent flow and surface tension, the drops would form into circles before they cooled, and they would cool from air flow before hitting the ground. If you did this with laminar flow, and a thin enough stream, you might be able to get the air to cool the metal before it has a chance to form into balls.

Maybe if you pre-burned the wood, it would work as a mold Also I think it's impressive how many things Dr. Stone DOES get right, because the author has to come up with these based on theory and definitely doesn't have time to test them

That works good with soft metal. You can use 2 sets of rollers mounted at right angles. It can also help to follow the rollers with a steel plate with graduated holes drilled through it. Use another set of rollers after the plate to help pull the wire through. Keep pulling it through successively smaller holes in the plate. Make sure your current hole is only slightly smaller than the current diameter of the wire. Heating the stock as you feed it into the rollers or pull it through the aperture helps too.

There was a lot of fun and novelty when we bought our boys a cotton candy machine for Christmas one year. Well, our older boy enjoyed it but our younger one is basically a mental toddler for life with his condition, so he just kinda watches what we do. Anyway, we pretty much burned through our spinning sugar within a week and it was honestly a LOT more effort (mostly in the cleanup) than just buying cotton candy. But we also took the machine apart and put it back together so I could teach my boy a little bit about mechanics (which is what we do with most of the stuff we buy that loses its novelty pretty quickly.) Not long ago, I caught him watching some of the "How to Make Everything" series and he was shockingly very apt at understanding a lot of the basic principles which gave me a lot of pride and satisfaction. Keep doing what you're doing man. Even if it only teaches a handful of kids what/how/why certain things operate (and are built), then you're putting an incredible amount of value out into the world. I've been trying to be as patient of a teacher as I can, but kids with ADHD are always either 100% or 0% invested into what they're watching. But the more stuff I can teach him, the better of a foundation he'll have for understanding further concepts and the more likely he will be to find what makes him happy. Thanks again, guys!

I would say Dr Stone is the reason i found this channel. I dont remember when i started watching but every video ive watched has been amazing

Near where i live is a “shot tower”, a brick tower that held a furnace at the top to melt lead, then this lead was poured through screens of various sizes and allowed to fall down inside the tower and through a shaft in the floor to a collection pool dug down into the cliff the tower is perched on. This was used to make small, uniform lead shot for use in shotguns in preindustrial times. The lead would cool as it fell through the air, and surface tension would cause the little droplets falling through the screen to take on spherical forms, with the water at the bottom to cushion the impact of them falling and landing on each other and to finish cooling them. I think that same principle might work with your laminar flow idea, if you can provide enough of a height of relatively windless space for the molten metal to drop through that it can cool to a point that it holds its shape before it hits water.

You have improved your content so much over the years. Great job!!

For casting wire, I think the press method used to extrude corn puffs should work better.

@feha92

Hmm, the test at casting a cotton candy machine through pressing into it showed that manually pressing into molten metal isn't too weird of an idea... So maybe if he gets a sealed crucible with a hole exactly fitting a pipe, and the pipe has a tiny hole in it throughout... then pushing the pipe into the crucible full of molten metal would cause pressure to rise, until it manages to push the metal through the pipes entire length. This is sort-of like his laminar flow idea, except using pressure instead of gravity, and a pipe long enough that the metal goes solid before exiting the pipe - leading to a wire coming out the end. I imagine relying solely on gravity won't work, as the friction inside pipe likely can't be overcome by gravity once the metal turns solid.

This is a great concept video for a concept video, for a video about a concept about a concept-based anime!

So spinning metal into threads might potentially work, but as you saw with the sugar, you need just the right temperature, and just the right velocity, and just the right hole size. And those will all be different for every different alloy. Plus the velocity limits the length of wire you can get pretty substantially. It's just not an efficient way to do it compared even to hand-forging, let alone using a draw plate.

That gear box frame would make a decent hand mill for grain.

A day with a new HTME, is a good day

Cool video! It’s unfortunate you didn’t seem to do your research on cotton candy making. Using the right sugar is the most important factor, if you had just tried your setup using only the white sugar from the beets it would have likely given you much better results

Started with a cotton candy machine, ended up with a drill press 😂

I think the basic premise of this idea comes from the industrial manufacture of rock wool (which is done in basically the same way by pouring molten slag into one of these centrifuges). Rock wool was first made though by just blowing compressed air into a stream of molten material so you could try that as well.

Seems like you would need a pretty high surface tension for the centrifuge to work. Also seems like molten metal as practically no surface tension.

@Silentspeaker3

Жыл бұрын

I think this issue is a more complicated than just surface tension. Surface tension is responsible for the beading of the metal, but when we look at things like glass or sugar, they stretch and bend long before they melt. We're dealing with a viscosity problem that may have a surface tension component. Molten sugar is fairly viscous, so it stays together as it is stretched/thrown, but most molten metals flow almost like water, so their ability to stretch (viscosity component) is fairly low, which causes them to bead (surface tension component). I'm certain there's more to the problem (fluid dynamics is complicated), but chasing this problem really isn't worth it when drawing wire works, so long as the wire is regularly annealed.

wire i imagine is more like a metal is plastic scenario where smithing and stretching is the best option. interesting to see other methods attempted but not surprised molten metal has surface tension and low viscosity that makes it not want to stretch into long wires.

I think maybe it's still possible if you don't melt it all the way. Part of the reason (at least from what it seems) is that cotton candy goes stringy because it's not quite liquid when it's either cooling or when it's being poured. So if you only heat up the gold to the point where it almost is liquid but still solid, it would be pulled and thinned rather than pulled and dropped. The other problem with that though is the rapid cooling could still give it thermal shock so maybe doing it in an enclosure that isn't as hot but still a temp closer to whatever the temp going in is at. The last problem is that this is still vary far-fetched to be done in the stone age and to have that type of temp control.

love how your mold was damp and it exploded. it's all most like your all ways in a rush

that wooden gear thing could probably improve your attempt at making a lathe, and/or a drill-press. just needs an extra bit to slot the end through so that it's more stable and doesn't start to wiggle. also, have you seen laminar flow tea kettles? find out how those work, and make a crucible that pours like a tea kettle out of a spout

Maybe it's a more complex idea than is worth testing, but your laminar pour method plus a rotating bucket of sand might work. Especially if the bottom of the sand-bucket was mesh and there was air pumping through the side that doesn't get poured onto. That way warm wire sinks and cools, while fresh wire falls onto empty sand.

Great vid as usual guys:)

i think your last attempt at an continuous casting setup was not that bad. might want the water closer to the metal outlet to cool it before it has a chance to form beads.

I enjoy Andy's brutal critiques of his methods. No embellishments here. It really goes to show that the biggest innovation of the industrial revolution was a transition from manufacturing based on mastery and craft to manufacturing based on raw labor, with the craft abstracted into machine creation.

This video reminds me a lot of William Osman where in one video they tried to put molten metal into a cotton candy machine which failed as with your video the explaination for it is that metal is just so heavy and viscous that it cant really form delicate strings and would turn into blobs and fling itself to the nearest wall

The reason why the sugar makes thin wisps when spun in the centrifuge is because when caramelizing sugar, the decomposition reaction causes the formation of polymers. These polymer molecules stick to each other through covalent bonds and form long chains that can be pretty thin even when in a liquid or semi-liquid state. Metal when melted still has its metallic bonds, but as temperature increases these bonds get weaker until they finally break when the metal boils. Molten metals don't have the same affinity to form chains like polymers do, metals like tin and copper have a fairly high surface tension so they'll just bead up. I don't know how viable cotton candy centrifuge wire is, but if you poured more molten metal in your metal container and the increased the tube length it would increase the pressure pushing the metal down the tube. If you had the tube actually submerged in the water, so the molten metal is not freefalling and having time to potentially bead up, it would start cooling the metal before it hits the water creating a steam explosion. Great video as always!

There are some good videos on making maple sugar from maple syrup. Simply take the finished maple syrup and continue boiling it until it reaches the hard ball temp. At that point beat it (example video used electric mixer) and whip air into it. As it cools a bit it will transition from a syrup into crystallized maple sugar. Spin extrusion is used for making rock wool so the basic concept works however it requires properly ductile material. Glass or molten rock fit that. Most metals don't. Gold, as you mentioned, is the most ductile metal and is far more likely to work than any other. As others have noted, the Dr. Stone machine had a constantly heated pot which is similar to modern cotton candy machines. That one you used of course is a bargain basement version that I have never gotten really good results out of in the first place. Considering the damage, still a better choice than spending several hundred on a commercial machine.

I have cast a few wire ingots of silver in wood moulds before. It actually works surprisingly well, at least when you use adrill hole it's not "safe" But it makes good ingots

Very cool stuff!

There are examples of wire jewelry and wire sculptures dating back to about 4000 years ago, placing it in the middle to late bronze age. Gold was poured into thin plates then pounded into sheet, cut into strips and rolled into wire. Once the iron age came around, the process was updated to hammering small rods into a grooved anvil. Drawing wire was also discovered around the same time and eventually overtook both of the other methods and is still used for most wire production today. Because gold work hardens the annealing process must have been used to prevent breakage in all of these methods. This means that copper wire was likely also being produced around this time. That said, gold has one unique attribute among materials of the time that made it a far superior option. Gold can cold weld. It is unknown if this was lost knowledge or truly not discovered until the 20th century. Since people were beating stuff with big heavy objects just to see what happens since the stone age, it's safe to assume someone had tried to get a broken piece of gold foil to go back together with the tools they were using to make it in the first place.

I really like your attempt with the actual candyfloss machine Oh and ps look into clocks you basically all but made a town clock with those gears.

I have to admire having the dedication to pour molten metal into a cotton candy machine

I wish you'd make a video about one of my favorite documentary series, James Burke's Connections, where he traces several basic inventions from their birth to our modern society of today; basically the history of invention and how they're all connected together

Can't wait for him to reach back to a camera now! Was my most awaited video before the reset!

I think the main thing you need to make it work with metal making wire is time... and that probably would need to come from distance. A somewhat similar manufacturing method that was used in production was for lead shot. They would drop it down from the top of a tower, often over 100'. A "Shot Tower" also used water to "catch" the molten balls at the bottom. The way they dispersed the molten lead into shot was by pouring through a copper sieve. I imagine to form wires the metal is likewise going to need more distance / time to travel through the dispersing orifice... think deep thru-holes vs holes through a thin material.

I'm nor sure how anybody else feels, but I've enjoyed you trying things from fiction and seeing if they work. Very Myth-Busters-y in the good sense! Dr Stone is a fun anime with at least plausible-ish ideas -- of course made better for fiction. It's fun to see them actually tried out!

I was always kind of skeptical of this one in particular, glad someone finally tested it

The problem is the sugar he used was too wet, the metal thing was too small and he had no heat source keeping it heated he changed way too much about the dr stone machine that it doesn’t disprove or prove it works

You could try drop forging the wire. Like how they used to make shot for guns. Get your laminar flow going high up, and instead of dropping into a bucket just let it air cool. I bet 6-10' might be enough to see results. Actual shot towers were pretty tall, but a thin wire has a higher surface area to mass ratio than a spherical bead.

1: gold (and pure gold at that) is one of the few metals with the correct surface tension, flow-solidify temperature ranges, and density to allow potential spin wiring, however, yes, you would have to be VERY exact in how you ran it and made it. 2: the sugar used for cotton candy is a huge factor in how well it works, and microadditives often massively change the effect. 3: he used a many year sun and salt dried aged non sealed plank, thus effectively fully drained of all sap, moisture, and other issues. Ideally you would bake the shaped mold in a kiln like hutch to further carbonize and dry it, but that has diminishing aid it gives. In many environments well aged wood is more reliable than common soil. 4: unlike the show, the manga went FAR more indepth into details and often hid exact numbers in the background illustrations

Maybe using a technique similar to candy makers making hard candy? As in, pour the metal in a way you can still move it while it is hot enough to still be somewhat soft but cold enough to not be liquid anymore, using two rolers to spin it and a system to pull and stretch it? Maybe that would be a consistent way to make a thin and maleable wire?

that flaming cotton candy machine was wild ! hehe

When trying to pour the wire in to the bucket do you think partially submerging part of the pipe in the water so I cools with no room to brake apart

Continuous casting, i.e. bars, tubes and wires from a crucible with a hole is a commercial process, but it's finicky, and the metal needs to be cooled so it's solid pretty much immediately as it comes out of the hole or actually just before, without actually plugging the hole. And the metal needs to come out at the correct rate too so the metal neither just all runs over the floor nor the entire crucible freezes. Apparently a water cooled copper block is uses to start the pour, extrusion or whatever you call it. I did hear that the Ancient Egyptians used to continuously cast wire for their chariots and bows, apparently it was pulled out under tension at a well judged rate. And either then through conventional draw plates. But this might be a complete fiction. I find it unlikely that they had anything remotely strong enough under heat. As well the advantages just don't seem to be there. If it's drawn anyway, and to have any strength it must, then it would seem that they would be limited to melting small batches anyway, and so they might as well cast an appropriate sized ingot and use that, either casting it to the right shape to get it through the first draw plate or more likely hot working a roughly bar shaped ingot into long and thin and pointy enough to pull it through the first plate.

You had me at Maple Cotton Candy! 🤤

Try using soapstone for making your molds out of. I have seen it used and works quite well.

At 10:15 you proved the old adage: "Any machine is a smoke machine if you operate it wrong enough!"

that anime is one of my favorites!

I love your primative videos can you please make more bows and arrows again cus I miss those ones

"...and after the battery, tune in next month when we make a TANK from paper, thanks for watching!"

I love this stuff

Dr Stone is a great example of “here’s the underlying idea behind the science” show. There is quite a bit of hand waving for the practical side of their methods.

Ya cooling it rapidly after coming out and getting an even consistent flow would be very important for making a nice wire.

"The worst part is, they started doing it two years before I did..."

Would it easier to make wire with the flow method by making it angled so it is slower in flow rate?

For the board method to be more plausible i would say to bake the top of the board and get a good char after carving. As well as carve deeper channels into the wood. Ideally this would take as much moister out of the surface as possible.

3:31 Let’s get this out in a tray. Nice!

The laminar flow one reminds me of how draw towers work in the production of fiber optic cable. Granted - I think molten glass is closer in physical properties to molten sugar than molten metals are (things like viscosity and surface tension).

for the copper wire and wood mold experiment, i think the wire was kinda thick. i'd wager half as thick as hemp rope. i know we use thin and tightly wound wires for motors. but the purpose of their wire was to wrap it around some iron ingots and have them struck by lightning to create magnets. i think i saw a comment on another video that made it sound feasible, just need to be in an area where one can set it up like a lightning rod

"worse part they started doing it 2 years before I did" oh man that made me laugh

That gear assembly could make a good drill press or a lathe

I kinda wonder if you could make the laminar flow wire work if you put it at the top of a tower and let the stream air-cool as it fell, so there was no impact with water. Also wondering if the wood casting would have worked better if you ran the wood thru a fire and charred the surface. Might drive off the water

To make wire, you can make a series of rollers with grooves that decrease in size as it is getting pulled, there could be an issue with mainatining constant heat and a consistent amount of force to "pull" it

if i could make a suggestion for the wire (as someone who has made silver wire) try casting a long ingot and pull it through a draw plate (easy to make)

I saw a video form the British Museum talking about Saxon gold artefacts, and the curator saying that the valuble stuff wasn't the big lumps of gold - its was the braided golden wire because wire was SO MUCH WORK to make

i like it that you testing anime stuff XD and you always doing something interesting. also the drop rate directly through the hole maybe too fast what if you let it flow out at an angle and a moving base?

HTFE = How To Fail Everything? I joke, love the channel!

YOOO I thought I was tripping when I saw Dr. Stone in the title. I'm a big fan of that anime because I love survival and science stuff.

Amazing how on some places you may leave things out to dry and not become a puddle like salt or sugar does here if not inside a sealed jar
