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.

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.

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.

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.

5:42 I've watched so much Forged in Fire that I instinctively found myself shouting oh no not a burn in!

If you can't beat 'em Join 'em!! Great work guys! I hope to offer a few pointers that might have made this more feasible for things that would have been known both to Senku and Kaseki. 1) I don't think the anime explains where he gets it, but in addition to the activated charcoal I believe Senku used Potassium carbonate, which (and again my chem is rusty and I was never that good to begin with) would have caused a double replacement decomposition I think leaving you with Potassium Sulfate, CO2 and Water. Someone that knows more about volcanic gasses and has had Chem in the past decade please check me. 2) Senku mentions it in the Anime, Hydrogen sulfide is denser than air, so it pools, and that's why his masks have the big glass chimneys. They're trying to pull air from where it's safer. Provided you have good seal, this is important. So the next tips will deal with how to ensure good seals. 3) Senku has billows, and they have a shallow pond area if you have someone to take the place of Ginro and Kinro, you can use the billows to inflate your tubing and check your tubing and mask for leaks, as steady stream of bubbles will let you know in a hurry where your problem area is. Or, and this is not shown in the anime, if you have bamboo and caveman glue or pine-tar etc. You can actually create any number of air or water pumps from that nearby waterfall. 4) Leather & Tube Tips: A)Making seamless leather tubing is hard, I commend you on what you've done. But there's an easier way, There are animal organs that you could prepare or use as an overwrap to make sure you contraption is actually gas tight. B) Keep in mind that all leather products are going to have a limited shelf-life and probably would need to be waxed before each use, C) The duct tape was a good idea, but you can improve seal over the mouth in several ways, such as taking the time to shape and fit the mask to the single face it was intended for (can be done with stiff leather, oil, and wax), you can fold the outer lip of the leather over to make a better seal / gasket that with crush / deform around your face better and make a more airtight seal, you can knead things into wax and create a semi-seal D) If you have a hand-spool and know the right knots, you can actually tension the leather down over the bamboo so tight that pitch / wax isn't truly needed, it's more of a secondary seal 5) Garrett Morgan's precursor to the gas mask consisted of multiple tubes to get to "clean air" (was also made of canvas, so you know leather can do the trick. Anyway, my point was if your air tube is located somewhere in the middle of your filter you could might potentially be able to trap any Hydrogen sulfide below your air intake, it's not that much denser than air so that's a maybe, but it'd be something to boost the effectivity of your device. Love the show, love the channel, those weren't criticisms, just somethings to consider. Before the reboot you'd occasionally try redoing things so maybe this is one you'd come back to. Last thing, you're doing great. More than a few things on Dr. Stone don't make sense. Chalk it up to even genius science users don't know the best ways to do everything. Your channel is awesome and thought provoking. Keep up the great work!!

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!

Really makes you appreciate all the hard work Senku must have done off screen.

To make your rock anvil more stable, try putting it on a shallow container filled with sand and/or small rocks.

man make more drstone stuff maybe a smoke bomb i love these doctor stone episodes

This series is just *AWESOME*

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

Awesome, SenkU for the video!

Louis is my boy so glad you guys worked together

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.

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.

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.

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.

You definitely need to reinforce the intake tube. Coiled wire can increase air flow.

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.

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.

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 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.

Dr stone is so awesome

glad I'm finally watching this non ironic asking the real questions

Ooooh now I wanna see this

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.

good works👍

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.

This guy understands how cool dr stone is

Charcoal has a number of useful benefits from basic gunpowder, water/air filters, to fuel for fire.

I would like to see a test with modern activated charcoal.

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
