Senku also said breath slowly or you'll overload it, but then you hooked it up to a vacuum pump. If you want a fair test hook it up to an aquarium pump. The air flow will be closer to natural breathing, just with infinite lung capacity. Senku also had lacquer thanks to the villagers. It's a better sealant and it's more durable. Just a few notes from a fellow fan of Dr. Stone. Other than that and making the hose to short, flawless job on the mask.
I suspect that in the chlorine test you just overwhelmed the filter. There was a crazy concentration of it in the container an a pump sucked it at a good rate. The charcoal didn’t have time to react.
Thanks for having me out Andy! This was a super cool project that people have wanted me to test for a long time, and I just KNEW you were the perfect person to do it with!
Fortunately you don't have to spec into technology too much due to insane bonuses from the social skill tree and the unique "global civilisation" trait most human builds have
In the anime they have a master craftsman to help them make what they want. This channel really doesn't have that so the fact that it even sort of works is kind of impressive.
@@TheElfsmith Oh. Hey. Yeah, I mean you and Joe are pretty great and make much better tools than Andy does himself. It's... Not a pretty sight. And then there's... What was it, the sword crafting guy? Can't remember. Anyways, point is, the experts like you that Andy has on the show sometimes is great and really bumps up the quality of the builds and adds to the overall knowledge and craftsmanship... It's pretty awesome.
Yeah this guy is almost hilariously incompetent. He's been making stuff for ages and everything still comes out looking like poo. And you can't forget how clumsy he is! Great entertainment
@@skrimper I mean... For every video he's juggling about four different fields of craftsmanship. Then there's rushing to complete the projects so he can regularly upload. And the fact that he never has the time to really practice or truly refine anything. But yeah... Sometimes it's a bit funny. Still, it's impressive that he can figure out building loads of stuff from scratch as well as he can without much more than possibly a year's worth of experience (at most) in each field.
yes and no, glasses only fog on an exhale, which wouldn't be an issue so long as the mask resealed on an inhale. That said half-face masks aren't the best choice for an air-tight seal, as the edges cover parts of your face that move as you turn your head or talk, which breaks the seal. it would be better to do a full face/head mask or to just stick the tube in your mouth as your lips can easily make an air-tight seal.
@@j.c.cannon2112 The fogging is still an issue because the resealing on the inhale isn't instant, so some toxic gas would get in before the seal was reestablished. Modern gas mask valves are designed to be sealed tight any time that there isn't a positive pressure pushing gas out, so they don't need an inhale to reestablish the seal.
"I wouldn't frivolously put myself in danger with this as my only safety device but if the danger were sufficiently unavoidable this is a better way to prepare than doing nothing" Makes sense to me
You know, I actually learned something from this show.... As a kid, I always thought that we just had crappy sawblades with their teeth bent... And as an adult, it never came up so it was never corrected...
That 8000 Generations or so of technological advancement is really f****** something. Every aspect of every piece of technology has something along these lines
Yeah, people tend to forget that people then were still people, homo sapiens. We haven't changed almost at all from that point. If you compare a today's person, with information readily available yet not necessary, and a person from the stone age, with information unavailable but an absolute necessity, you realise how gosh darn smart they were. And also remember that the average lifespan back then was like what, 25 years? Before agriculture came by, everyone's everyday lives was gathering food practically nonstop, so just imagine even finding time to think of ideas, craft and test all these things we do today, and let alone perfect them and teach the new generations how to make them. We were goddamn smartasses, just like we are now, we haven't changed.
@@dankovac1609 Actually, it wasn't just "gathergathegather" back then, unless you were living solo, as group efforts would create prosperity for your tribe, and a few medium to large animals hunted would provide food for many days with little issue, as would a grand harvesting session (while agriculture wasn't a thing, the concept of noting areas of good food in good quantities was definitely already there). Furthermore, the "average lifespan was what, 25 years" was because of how the average is calculated. Birthing complications resulting in death for the child, the mother, or both were far more common, and a dead-at-birth baby adds 0 years while adding oone to the number of datapoints (and thus the divisor for the average). Once you survived past young childhood, you became much more likely to survive and lasted up to the current average human lifespan, with maybe 10 years taken off for end-of-life care artificially extending it beyond what they were technologically able to do.
@@KainYusanagi thanks for correcting me. Yes i do understand that it wasn't just gathering, and the tribe could prosper. I just wanted to say that just keeping living conditions back then was a challenge for everyone and it's impressive that we managed to invent so many things because of the necessity. I tried to compare it to today, where your life expectancy is incredibly higher and you have access to all the information of the whole species and it's history. Yet there's also much less need to invent and an average man will achieve far less in the comparatively much longer life. I also do understand that we weren't just limited to 25 years of life, and many grew far older and became great wise elders, of course. But it is my point that so many different sicknesses, injuries and such could kill you far easier, and it happened more often than today. To sum it up, i wanted people to think about what's more "advanced": Inventing miracles with optimal life circumstances and thousands of years of knowledge on your side, or inventing completely new things out of outmost necessity with only your own bodies and minds, using the skills of a couple generation's advice?
17:04 Fun fact in the show they explain that the masks will only last for so long so they have to work fast while not breathing up all their filtered air.
You could theoretically seal the edges of the mask to your face with clay or mud, but then you wouldn't be able to talk or move your mouth much without breaking the seal. Awesome video, now I gotta go watch Dr Stone lmao
@@Lucid-o7z soft wax (wax and olive oil), not body wax wax. In proper proportions the mixture should be similar in consistency to vaseline (which fun fact, can be used on gas mask if you are not clean shaved for better seal).
I definitely think that the chlorine gas produced in that box was way more than the charcoal could effectively absorb. Maybe if it was a lower concentration mix with the air, the results would have been better?
I dont want to be that guy, but please keep in mind gas masks ADsorb chemicals physically, they dont ABsorb. Its a important difference and the reason they want the most surface area. With absorption it would be irrelevant, because there only the volume counts. Also, i think if they cooled it down somehow it would adsorb way more of the gas, cause the brownian motion wont be as high as with higher temperatures and therefore the molecules would stay more on the surface. They should do a follow up video where they try some upgrading.
@@Aochso There's also the issue that the pump was probably pulling air way too fast. In the show, at least, Senku stresses that you shouldn't panic and hyperventilate, because the filter won't be able to keep up with you panicked breathing.
As some others have also said, if you use that leather tube again, some ribs inside the tube will keep it from collapsing then there is negative pressure such as breathing in while using this gas mask. Great video!
waiting for Private Internet Access or NordVPN to sponsor the next video with a guide of how to circumvent regional blocks (for example on crunchyroll lmao)
It would be interesting to compare this to the last-resort method used by soldiers in WWI: Urinate on cloth and breathe through that. Obviously, don't show the "making of" that, and I'm sure it didn't smell too great, but it is something possible with the level of tech you're currently at.
ah yes the French method. my dad works in has mat and is a history buff so i have a good understanding of the "hilarity" of the development of the gas mask. such as the fact the fers mask with changible filters was made for dogs.
I think the point of that was just to get it wet. As a protester, one of our ways of dealing with police gas attacks is with wet shirts over our faces. That's also good to do in a house fire to avoid smoke inhalation. Piss is optional.
I'd say that especially since in the show they spent I think a bunch more time making multiple iterations on the mask system, so assuming that the issue with the one in this video was a hole in the tube or something, I'd definitely believe that with a few more attempts at making more airtight of tubes, as well as with some more work put into tightening up the seal on the mask bit, this could absolutely work.
Best part about dr stone is a lot of the science they use would pretty much work irl (with the exception of small fictional deviations, such as foxtail millet actually being able to be made into a noodle that doesn't crumble instantly)
UA-cam still doesn't put these videos in my recommended feed even though I watch every video on release and have subscribed and notifications turned on. I'll keep thumbing them up and hoping for the best :)
The rabbit reminds me, have you gone over tanning leather? (You probably have I just don't remember). I would like to see you go over textiles and clothing, using skins and leather, along with linnen and silk. And any other cool stuff you can do with that.
Fun tip I learned in usmc cbrn school... standard gas masks will not effectively stop chlorine gas. Chlorine gas can basically chew straight through standard gas mask filters in about 40 minutes or so, give or take. To prevent this issue, non standard, expensive and special filters and/or filter attachments have to be used.
there is an old Danish book on medieval tech and one of the projects in it is an air tight diving suit with a breathing apparatus. maybe fallow what you can in the book if your interested in improving this design
You didn’t actually make activated charcoal, the potassium carbonate doesn’t „activate” it, but it helps, running 300°C steam trough it will. Cody wich you made glass with has a video on activated charcoal
maybe make saw with smaller japanese style teeth so you don't produce so many thin cracks along the grains of the bamboo. The one way valves really need alot more care and thought into how it's made, after testing, I found that rabbit leather works the best. there's really no good way to seal it properly by just directly making a bun over the valve, so depends on how accurate you want to get towards the source material, you might want to roll the leather over the valve, and seal the end like the butt of a tube of toothpaste, making sure the stitch and sealant is airtight. reverse it, cap it over the valve, tie it down lightly with leather string and mark spots for holes just right above the string(about 1.5~2mm apart) and puncture the holes from the underside. You don't need more then 5 holes each valve. Carefully make groves around the valve where the string is then reattach leather cap back to valve and tighten with leather string. and the glue application, oh god the glue application. the glue you've made is great stuff, but you're trying to seal pipes not dabbing vegemite to toast. Get a piece of twig and crush the end or use your hair to make a brush, then brush it on the valves in layers like you would a pipe. Brush nice even thick layers on the outside where the grains of the bamboo is exposed to seal it up. Just dabbing it on cracks doesn't get it completely into the cracks and it will leak. also bamboo isn't pvc so be mindful of the tube-like fibers it's made out of.
Should of used some small bamboo rings to line the inside of the tube to make it easier to breathe. Don't need to be glued or anything just stacked up on top of each other and boom, flexible reinforcement. If you want to go fancy then use some green willow branches and weave a loose tube net.
I just finished season two of Dr. Stone and I think we also have to consider the fact that Senku is crazy smart. I could follow most of the science and even predicted a few things but would not be able to replicate most of it without a lot more trial and error. Minor spoilers for Dr. Stone ahead. I would have started out a lot simpler than Senku. He makes a lot of big scientific leaps at a time in the show like making a working car or phone. I'm glad the show has some limits on what he can accomplish (a true cellphone would have been hard to believe). The show is really fun though. Get excited.
For the chlorine it might have been more effective if you had used wet fabric in the filter like they did in WWI or wet limestone pices to neutralize it.
in the show they say them selves that it does not work if you breathe too quickly, if the pump is drawing too much air, the filter does not have time to do its job. thats also why you dont smell anything i bet, because you are drawing in less air than the pump was. you should try the gas test again but the pump going 10% of max draw speed or slower, the goal is to go slow breathing speed.
Preface, I’m not a blacksmith, just an enthusiast, but the fact that you are still blacksmithing on a rock kills me. So my suggestion is, can you make an anvil out of iron or bronze what works better than a rock. It doesn’t have to look like an anvil as we know them it could be a cylinder no bigger in diameter then the bottom of a solo cup and slammed into a log to keep it from moving so much. Just wanted to chip in. This will probably get buried.
I was thinking that maybe part of the reason it works in the show is because the intake is held higher up where the parts per million of toxic gas is less (assuming it's not a windy day) which can help survive a but longer. As for the seal, if this was something truly life or death, they could also have opted to add some of the glue or sap around the mask while on the face to make a more air tight seal. The better the seal the safer you are after all!
the vibe keeps getting closer and closer to mythbusters tbh, which is great. Y'all dont quiiiiite have the same funding yet but definitely the same spirit!
I'd say that the reason why the strip reacted to the gas was because the exhale tube is open when the mask is tested, because the test subject doesn't exhale and it is not sealing the one way valve thing.
you can put segments of bamboo inside the leather tube, it might be that the lack of air circulation inside the collapsed leather tube is creating a vacuum inside the mask itself and the as you said the plastic of the mannequin is letting the chlorine gas penetrate
Q: With hydrogen sulfide (H2S) gas, would you be able to know that you're dying before you're dying? A: No. I don't know what they say about this in the anime, but in the manga Senku tells a story about how some researchers went into an area with H2S gas around their feet (they didn't realize), and one bent down to tie his shoe. His face hit the gas and he was dead before they realized anything was wrong. This also jives with what I've heard in my HAZWOPER training when they talk about going into confined spaces and the dangers of "sewer gas". H2S gas is nasty stuff.
Do you think that might have been the gas mentioned in "Little House on the Prairie" (the book, not the TV show) that had Pa lowering a candle into the well he was digging to test the air? His assistant thought the candle was a waste of time and went down the well one morning without it, he ended up fainting at the bottom and Pa had to tie him to the rope and pull him up. But both men survived, and Pa used a makeshift bomb (a bit of gunpowder tied in a cloth) to get rid of that gas so they could keep digging.
Wait but what about that one way valve that you made on the sides? You need active breathing for it to work, no? It closes off only on suction and opens on breathing out - so blocking path (well not fully but still) for outside air to get inside. On video it seems as if you just let it be - so it should be open.
@@Heliosmaster Maybe they didn't use strong enough pump? It doesn't look moving valve to me on camera. If pump is on the end of the thing that too changes how strong it should be.
I would've used obsidian to cut the leather, it's far sharper than a regular iron knife could ever be and it has no risk of breaking cutting leather. There's a fourth way to activate charcoal as anyone that watches Cody's Lab knows... superheating it. The big thing about your rig is it's maybe 1/50th of the size of the one on the show. I think if you had a way to upsize it, it'd probably work... so long as it's sealed properly. Increasing the length and adding a distribution block carved from wood on each end, you could also add multiple pieces. 5 or 6 of the same diameter pieces you had at about 30-36 inches would likely be about the same volume as the one on the show.
Maybe would have been a good idea to have a second tub to put the mask in, so the filter is in the tub with the gas, but the mask being measured is in the other fresh one. That would have sorted out if it was the mask no working, or just improperly fit.
crushing charcoal does not increase the surface area per-se. The surface area you are accessing from activated charcoal are microscopic pits embedded withing the structure of pieces of charcoal. if you destroy that structure completely to fines or dust or powder you destroyed the structure. Also acids may increase the porosity of the charcoal structure, but steam activation does this orders of magnitude better. the charcoal needs to be heated back up to the original temperatures used to create it, 500C to 800C, and introduce steam to the material. The cave man way of doing this would be to simply terminate your pyrolysis pit with water (slowly), before completely drenching it to remove all heat energy. Whats left will be much more activated (and larger quantities) than if you smolder-ed and acid-ed the carbon material. you can test the resulting material from your method and what i described with the iodine test for each materials adsorption ability.
i would have put a bunch of short pieces of hollow bamboo inside the tube so that it didn't collapse when you breath in but it could still bend. maybe attach them together with leather and tar before putting it in the leather tube and that would add another layer of sealing. I would have also liked to have seen your mask tested with the choline gas using a modern filter to see if it's the homemade charcoal that was the issue.
Man, the ideas for this channel are briliant, If you would cut all the boring parts where you talk about you and your friends, reducing the videos to a 10 minutes size I'm sure you'll get 3 million views in 3 months, and not 300ks. Nobody cares about anything else but the project itself, jump directly to the subject.
Maybe try making a mechanical pressure spacesuit? Everything apart from the helmet can be tightly wound strips of whatever to push the skin back together

Charcoal has a number of useful benefits from basic gunpowder, water/air filters, to fuel for fire.
UA-cam still doesn't put these videos in my recommended feed even though I watch every video on release and have subscribed and notifications turned on.
I'll keep thumbing them up and hoping for the best :)
The rabbit reminds me, have you gone over tanning leather? (You probably have I just don't remember). I would like to see you go over textiles and clothing, using skins and leather, along with linnen and silk. And any other cool stuff you can do with that.
I believe they're actually his first handful of episodes, Different format but still worth the watch
Fun tip I learned in usmc cbrn school...
standard gas masks will not effectively stop chlorine gas. Chlorine gas can basically chew straight through standard gas mask filters in about 40 minutes or so, give or take. To prevent this issue, non standard, expensive and special filters and/or filter attachments have to be used.
there is an old Danish book on medieval tech and one of the projects in it is an air tight diving suit with a breathing apparatus. maybe fallow what you can in the book if your interested in improving this design
Name and autor?
do you know the name? thx
You didn’t actually make activated charcoal, the potassium carbonate doesn’t „activate” it, but it helps, running 300°C steam trough it will. Cody wich you made glass with has a video on activated charcoal
maybe make saw with smaller japanese style teeth so you don't produce so many thin cracks along the grains of the bamboo.
The one way valves really need alot more care and thought into how it's made, after testing, I found that rabbit leather works the best. there's really no good way to seal it properly by just directly making a bun over the valve, so depends on how accurate you want to get towards the source material, you might want to roll the leather over the valve, and seal the end like the butt of a tube of toothpaste, making sure the stitch and sealant is airtight. reverse it, cap it over the valve, tie it down lightly with leather string and mark spots for holes just right above the string(about 1.5~2mm apart) and puncture the holes from the underside. You don't need more then 5 holes each valve. Carefully make groves around the valve where the string is then reattach leather cap back to valve and tighten with leather string.
and the glue application, oh god the glue application. the glue you've made is great stuff, but you're trying to seal pipes not dabbing vegemite to toast. Get a piece of twig and crush the end or use your hair to make a brush, then brush it on the valves in layers like you would a pipe. Brush nice even thick layers on the outside where the grains of the bamboo is exposed to seal it up. Just dabbing it on cracks doesn't get it completely into the cracks and it will leak. also bamboo isn't pvc so be mindful of the tube-like fibers it's made out of.
Never heard of Dr Stone but it looks great! Going to have to add it to my list
Should of used some small bamboo rings to line the inside of the tube to make it easier to breathe. Don't need to be glued or anything just stacked up on top of each other and boom, flexible reinforcement. If you want to go fancy then use some green willow branches and weave a loose tube net.
I give this guy my respect for showing the anime scenes in sub
I just finished season two of Dr. Stone and I think we also have to consider the fact that Senku is crazy smart. I could follow most of the science and even predicted a few things but would not be able to replicate most of it without a lot more trial and error.
Minor spoilers for Dr. Stone ahead.
I would have started out a lot simpler than Senku. He makes a lot of big scientific leaps at a time in the show like making a working car or phone. I'm glad the show has some limits on what he can accomplish (a true cellphone would have been hard to believe). The show is really fun though.
Get excited.
Great job guys! Dr. Stone is the Tony Stark of his time
For the chlorine it might have been more effective if you had used wet fabric in the filter like they did in WWI or wet limestone pices to neutralize it.
in the show they say them selves that it does not work if you breathe too quickly, if the pump is drawing too much air, the filter does not have time to do its job. thats also why you dont smell anything i bet, because you are drawing in less air than the pump was. you should try the gas test again but the pump going 10% of max draw speed or slower, the goal is to go slow breathing speed.
Preface, I’m not a blacksmith, just an enthusiast, but the fact that you are still blacksmithing on a rock kills me. So my suggestion is, can you make an anvil out of iron or bronze what works better than a rock. It doesn’t have to look like an anvil as we know them it could be a cylinder no bigger in diameter then the bottom of a solo cup and slammed into a log to keep it from moving so much. Just wanted to chip in. This will probably get buried.
I was thinking that maybe part of the reason it works in the show is because the intake is held higher up where the parts per million of toxic gas is less (assuming it's not a windy day) which can help survive a but longer. As for the seal, if this was something truly life or death, they could also have opted to add some of the glue or sap around the mask while on the face to make a more air tight seal. The better the seal the safer you are after all!
You definitely need to reinforce the intake tube. Coiled wire can increase air flow.
bro ive been reading the manga for the past 3 years and idk how to describe my joy about this
the vibe keeps getting closer and closer to mythbusters tbh, which is great. Y'all dont quiiiiite have the same funding yet but definitely the same spirit!
Improvement idea cut lengths of bamboo and hollow them out to keep your tube from collapsing and the cuts will allow gaps for flexibility
I'd say that the reason why the strip reacted to the gas was because the exhale tube is open when the mask is tested, because the test subject doesn't exhale and it is not sealing the one way valve thing.
you can put segments of bamboo inside the leather tube, it might be that the lack of air circulation inside the collapsed leather tube is creating a vacuum inside the mask itself and the as you said the plastic of the mannequin is letting the chlorine gas penetrate
Q: With hydrogen sulfide (H2S) gas, would you be able to know that you're dying before you're dying?
A: No. I don't know what they say about this in the anime, but in the manga Senku tells a story about how some researchers went into an area with H2S gas around their feet (they didn't realize), and one bent down to tie his shoe. His face hit the gas and he was dead before they realized anything was wrong. This also jives with what I've heard in my HAZWOPER training when they talk about going into confined spaces and the dangers of "sewer gas". H2S gas is nasty stuff.
Do you think that might have been the gas mentioned in "Little House on the Prairie" (the book, not the TV show) that had Pa lowering a candle into the well he was digging to test the air? His assistant thought the candle was a waste of time and went down the well one morning without it, he ended up fainting at the bottom and Pa had to tie him to the rope and pull him up. But both men survived, and Pa used a makeshift bomb (a bit of gunpowder tied in a cloth) to get rid of that gas so they could keep digging.
Wait but what about that one way valve that you made on the sides? You need active breathing for it to work, no? It closes off only on suction and opens on breathing out - so blocking path (well not fully but still) for outside air to get inside. On video it seems as if you just let it be - so it should be open.
they mention that the pump was simulating breathing, in & out
@@Heliosmaster Maybe they didn't use strong enough pump? It doesn't look moving valve to me on camera. If pump is on the end of the thing that too changes how strong it should be.
Every video I open up of yours is like Christmas.
Man. I cannot wait for dr stone s3. He said go to another continent. As a geography nerd I cannot wait a second
I would've used obsidian to cut the leather, it's far sharper than a regular iron knife could ever be and it has no risk of breaking cutting leather. There's a fourth way to activate charcoal as anyone that watches Cody's Lab knows... superheating it. The big thing about your rig is it's maybe 1/50th of the size of the one on the show. I think if you had a way to upsize it, it'd probably work... so long as it's sealed properly. Increasing the length and adding a distribution block carved from wood on each end, you could also add multiple pieces. 5 or 6 of the same diameter pieces you had at about 30-36 inches would likely be about the same volume as the one on the show.
You did not make activated carbon. Actvation, even in presence of base or acid, requires temperatures in the range 250-600 C.
You should make a pump for ur next video, which could help u in developing knowledge on how to make a piston.
yea they made a valve and a pump is just two valves facing each other.
Gas mask: a full face respirator with style filter.
Half face respirator: What they made in this video.
Maybe would have been a good idea to have a second tub to put the mask in, so the filter is in the tub with the gas, but the mask being measured is in the other fresh one. That would have sorted out if it was the mask no working, or just improperly fit.
I liked how he had this channel first set up
i think you made everything for this episode!
Legendary channel.
crushing charcoal does not increase the surface area per-se. The surface area you are accessing from activated charcoal are microscopic pits embedded withing the structure of pieces of charcoal. if you destroy that structure completely to fines or dust or powder you destroyed the structure.
Also acids may increase the porosity of the charcoal structure, but steam activation does this orders of magnitude better. the charcoal needs to be heated back up to the original temperatures used to create it, 500C to 800C, and introduce steam to the material. The cave man way of doing this would be to simply terminate your pyrolysis pit with water (slowly), before completely drenching it to remove all heat energy. Whats left will be much more activated (and larger quantities) than if you smolder-ed and acid-ed the carbon material. you can test the resulting material from your method and what i described with the iodine test for each materials adsorption ability.
i would have put a bunch of short pieces of hollow bamboo inside the tube so that it didn't collapse when you breath in but it could still bend. maybe attach them together with leather and tar before putting it in the leather tube and that would add another layer of sealing.
I would have also liked to have seen your mask tested with the choline gas using a modern filter to see if it's the homemade charcoal that was the issue.
Season 3!
Let's goooooooo
This guy understands how cool dr stone is
It's so cool to see the anime is actually scientifically accurate as hell
the way he said “manga” 1:58 just killed me
menga
Let's go, another Dr Stone episode!
Man, the ideas for this channel are briliant, If you would cut all the boring parts where you talk about you and your friends, reducing the videos to a 10 minutes size I'm sure you'll get 3 million views in 3 months, and not 300ks. Nobody cares about anything else but the project itself, jump directly to the subject.
I just started the show and immediately thought about this Channel and of course you already have videos on it I love you so much homie
Maybe add bamboo splinter ring ribs to the hose to keep it open, ideally it would be a coil of wire inside it.
Or any kind of bramble that you can basket weave with
I have mo idea how Boichi keeps being so on point
Maybe try making a mechanical pressure spacesuit? Everything apart from the helmet can be tightly wound strips of whatever to push the skin back together
Dr. Stone is one of the two anime I'm waiting for the third season. If anyone wants to know, I'm waiting for Arifureta.
Would be worth a revisit this should definitely have worked as this is how we made Great War era gasmasks and they worked .
DUDE ive been a huge fan of dr stone and wondered about the builds in it if they would work. I cant believe im just finding this now!
I haven't watched this channel since 2019 well now I'm back
I would like to see a test with modern activated charcoal.
Is it possible the pump was over taxing the charcoal like heavy breathing might like in the show? Maybe that is why it was failing the first test.
That pole saw you made was pretty legit man lol nice work Andy
I love that this channel is half science half cat
glad I'm finally watching this
non ironic asking the real questions
Hey is Louis Weizs, The Guy who created a Slap machine to cook a chicken
Looks like something that would genuinely be used in ww1
FINALLY GOT THAT SPONSORSHIP LETS GOOO
now we just need a WW1 era machinegun
