TO SHOW YOU THE POWER OF FLEX TAPE, I MADE A SPACE SUIT OUT OF IT

"Does duct tape work in a vacuum? You may ask. The answer is, of course it does. Duct tape is magic and should be worshipped."

10:22 "you don't need hundreds of rolls tape, you just need one or two" *flips off the people who think you need hundreds of rolls*

Just finished 'For All Mankind' and i laughed when they took out the rolls of duct tape. One thing though, during the scene you could see the tape coming off or unraveling and blood boiling off into vacuum. Can't imagine the agony that must feel like.

>"You don't use duct tape to fix your air ducts." >Proceeds to describe how to use duct tape to reinforce human air ducts.

Hello, i am aneaesthesiologist and great fan of your channel, but I have to point out that you made a mistake. 4:34 you said that lungs will rupture and gas bubbles will go into the bloodstream causing embolism. That's not the mechanism of barotrauma - lugs will rupture and gas will break delicate structure of alveoli of the lungs causing pneumothorax - gas will enter the space between lungs and ribcage, and with each breath there will be more gas in this constricted space, essentially creating one-way valve, thus raising the pressure inside the ribcage, compressing the lungs and the heart. Veins entering heart and a part of the heart called atrium is very soft, so when compressed it will restrict the amount of blood, lowering the blood pressure and causing a blackout. Cheers from my nighshift!

Red Green approves of this video.

Hey Scott, loved your analysis! I noticed something during the episode that might influence it. Molly mentions a time or two that they'll need to empty their lungs before going out. That mention, plus the lack of an apparent oxygen supply for their masks, seems to imply that Gordo and Molly are actually just powering through this thing with empty lungs, rather than getting any air from the masks. They appear to be using them as a rigid element to cover their faces and still have some visibility rather than life support. It seems like the lack of oxygen is the limiting factor to their time of useful consciousness, since the suits seem to do a decent job for what they are.

The problem with making a scene like this more realistic, is that more people would complain it is too far from reality...

“Duct tape is magic and should be worshipped” - Mark Watney

By far one of the best episodes ever made. Seriously. So many emotions, so much anxiety, and so much connection to 2 of the best characters ever written for screen. For All Mankind is FIRE. ACES. Perfection. Finally a show that has real emotion.

Thing is, those two characters didn't have _oxygen masks_ . They just had gas masks poorly pressed against their faces in vain attempt to slow down desiccation of their eyeballs. However, upon decompression, the moisture would precipitate immediately and cover the mask with frost, rendering their view unusable. They did exhale air to prevent pulmonary rupture which doesn't make much sense if they already wanted the masks and tape to work. So in theory, running like 25 m there and back, to switch few cables and press a switch or two is possible, but it would require a lot of duct tape (they were poorly wrapped in the scene), mask held firmly against the face, probably some aluminium foil to prevent thermal damage to the tape, and breathing pure oxygen for few minutes before leaving. Injuries would be inevitable, as well as pain, but one could survive and likely stay reasonably focused during 15 s. The couple died because nobody administered emergency help after pressurization.

Scott continues his tradition of flipping us off every episode at 10:26

Congrats for Scott Manley starring as a Soviet moon base commander, excellent performance!

Thanks for the science on this, it was fascinating to learn it! What bugs me the most is, why would NASA not have an emergency suit next to EVERY airlock in case of emergencies? It seems outside of their normal safety margin, something they discussed in a couple episodes. I would have to agree that they definitely shopped at 'convenient plot device'-mart. Ending made me sad, which it was supposed to do, as well as highlight the dangers in space. Overall love the show, excited for the next season, which I hope focuses more on tech and less on relationships...

Wish Mythbusters was still on the air. I can totally see them doing this one with the help of NASA and an instrumented Buster.

- "Manufactured by Generic Plot Device Corporation" Hollywood should use that more often.

Woman to Macgyver: Are you one of those guys who can build a missle out of a paper clip? Macgyver: Why? You got one?

I'm really glad they didn't make that scene any longer! It was tense enough as it was! I'm usually pretty restrained, but I was yelling at the TV for them to hurry.

This was great. MAN that last episode is arguably up there with some of the greats. The duct tape scene was fantastic emotionally, visually and spawns convos like this vid.

"Duct Tape is Magic and Should be Worshipped" ~M Watney. "Can you actually make a Space Suit out of Duct Tape?" ~S. Manley. "Why I actually HATE Duct Tape!" ~Adam Savage

9:56 "The great thing about tape though is... if it is not strong enough, you can just add multiple layers" - a words to live by.

How the hell this show went under my radar until just now is beyond me. I'm gonna start watching it tomorrow.

I had to pause the video for 20 hours to watch the show, because I've never heard about it before, but it was worth it.

"the human body is actually mostly there to support this brain up here" Gonads: You really think so? That's precious.

Let's not forget that Ductape saved Matt Damon on Mars

Thank you for that video. That was one hell of a hard scene to watch because I love those two characters but it did make me wonder if it was even close to being doable. So I was glad that you made a video on it.

That scene was heartbreaking and difficult to watch. At least for me.

In the show I don't even think they hooked up the face masks to an O2 tank. I think they just used it to protect their faces. That better explains why they only had 15s before loss of consciousness

“Ok thank god we got back to the ship alive!” “Yes, yes. Let’s take the tape off now!” “Wai-“

Great video! That scene was legitimately heartwrenching, but I was curious about the science. Also, had to smile seeing the Profundity Mon Cal cruiser on your shelf. If it's the Fantasy Flight mini, I was the game designer on it when I worked there. 😆

What I've been learning over the years from various analyses of fiction involving exposure to hard vacuum, is that we consistently overestimate how deadly it is.

Someone has probably said it already but grey tape was crucial in the Apollo 13 “Square peg, round hole” fix, arguably the most historic grey tape fix in orbit.

"Generic Plot Device Corporation" is my new favorite thing.

Turns out Gordo's mustache accounted for 35% of his suit's structural integrity.

That scene was so freaking amazing. No spoilers but I was on the edge of my seat the entire time

Duct tape is like the Force: it has a light side, a dark side, and it holds the universe together.

honestly this scene shook me so much, especially when blood started spurting out of the cracks

My take away from this: you're always tens of seconds away from death.

I’d just wear what the camera crew had, they seemed to of stayed out longer 😉😊

"Fly safe", he tells me after teaching me how to make a duct tape space suit, and previously a fire extinguisher manuvering unit,...

This plot-point was so fastinatingly haunting, I am uncomfortable even remembering it. The fact that they realistically could have survived that makes it even worse somehow. Thanks for that, I guess.

This video is exactly what I expected and wanted it to be. Thank you.

there's just something rather concise elegant alluring and charming about those old-fashioned graphs like in 3:40, so much information yet so intuitively presented

As a squba diver i love that a lot of the problems with pressure differences are the same as if you are going to space. The number one rule when scuba diving is never hold your breath especialy when ascending or decompressing

Scott: “Minor spoilers from For All Mankind” Me: dont do it Scott: I won’t tell you who wears the suits tho Me: thank goodnesses Scott: *shows their faces* Me: damn

One of your best Scott !

A man has been exposed to a vacuum, and survived. His name was Jim Leblanc.

You and Adam Savage both posted a video on duct tape within 40 minutes of each other. And both mention how bad it is for ducts almost immediately upon starting to talk about it. Love it

That scene when they find out what happen after they got back in was rough.

Great video as always. I happen to teach aeromedical training to pilots and aircrew and I could probably just play part of this video sit back and enjoy a cup of tea and my students would still get the bulk of the info they need. Not sure how I missed this when it came out. Just some bonus info Pre-breathing O2 does more then just add some extra oxygen in the tissues. If they were breathing a nitrogen oxygen mix before the exposure then there would be a real risk of decompression sickness (DCS) occurring as the nitrogen bubbles out of their blood like co2 does when opening a can of soda. If you switch to 100% oxygen for a couple of hours before hand you can off gas the majority of the nitrogen dissolved into the blood and minimize the effect of the DCS.

I cried myself out on that scene. Felt so real and with so many emotions going.

As far as I could tell the masks in the show were just to protect their faces, they breathed out as much air as they could and held their breath. The mask wasn't pressurised.

I like to think that I'm addition to getting the Medal of Honor as a civilian, Tracy was given the title of Honorary Marine for consistently helping the Moon Marines on their missions.

Scott, you are just the best. Thanks for this video. It brightened my day.

for all mankind is a really good show, i was very weary after the first 2 or 3 eps but then it really kicked off and i thoroughly enjoyed the rest

As someone who's helped make and had made on them duct tape suits for costume sizing I can confirm some of this. One to two rolls per layer is about right depending on the size of the roll. And they can absolutely create enough pressure, even accidentally, to completely stop your ability to breathe causing people to pass out. I absolutely believe this that they could create enough pressure to act like a pressure suit

I once read somewhere about an oopsie with a spacesuit in the big vacuum chamber at JSC. The guy lived, everything was fine, but I remember one detail of his description of events -- apparently having the saliva on your tongue boil is a very strange feeling, because that's when he realized the scale of the malfunction.

That was a cool scene, but the one that really had me wondering was the episode with the solar storm. Would any amount of radiation cause that sort of effect on the regolith?

Love it! Great video thanks for sharing!

I love the new intro with the Kerbal =)

Generic Plot Device Corp Delivering you the exact specifications to move your story forward

Fun fact, (as a painter who had stretched many canvases from duck cloth, I'll never get tired of this,) "duct" tape comes from the Dutch word "doek" which simply means canvas or cloth, and I believe was originally used as strips of cloth to repair sails, without ant adhesive backing. Anyway, "doek" is commonly anglicised as "duck," so it's actually more accurate to just call the stuff, "duck tape," since it's no better for use on ducts than it would be on actual ducks. Also gaffers tape is just infinitely better and should always be used in preference when available, (and in most cases is actually adhesive backed cloth, meaning it would be most accurate to call it doek tape instead, but this is English and we don't use words for their etymological consistency around here.)

Your videos are always very informative and entertaining.

Hi Scott! The masks that appear in the series are not for oxygen, but for face protection. It is mentioned in the series that all the oxygen in the lungs must expire before they can come out.

It shows my age that I'm wondering about the 2001 scenario .... 'Open the pod bay door, Hal'.

Scott, you're just amazing. Keep it up. You bring the hard core science and math that the other don't, and it never gets dull.

Its rare that we see a solution that work in real world in a show but that in the show it works less optimally than it will do in real life. Usually its the other way around lol.

All my questions have been answered... Ferb, I know what we are going to do today!

glad to see somebody is not too afraid to answer the real questions

I love for all mankind. Thank you for recommending it. Love your channel too.

That was a great scene, and a very moving moment in the series.

You should do more videos on for all mankind (Pathfinder shuttle, the moon base, etc...)

Bye Bob 😭 My poor Gordo and Tracy went out like Champs. A sad yet great end to great characters and character arcs.

Brilliant. Informative. Funny. As usual.

Great info, was wondering about this after seeing the particular episode.

Ahh gordo, my homie kept it real on the streets

Just imagine you survive and you need to pull all the tape off your skin. Woohoo!!

the fact that the body knows how to recover from a vacuum is astonishing

"Generic Plot Device Corp".. hahahah... That one got me Scott. Well done Sir, well done.

I will have to verify all this with "Red Green"

I once gifted a family of truckers a bunch of duct tape and zipties as birthday day gift. Everybody laughed. Many months later we meet again and they said - it literally saved them on the road.

Imagine being a network manager or executive producer for this show. You come to visit the set to see how filming is going and how the budget is being spent. You expect to see some amazing set pieces, cool astronaut costumes, maybe catch a space gunfight scene being filmed. But then you see two of the actors wearing gas masks, covered head to toe in duct tape, running across a green-screened sandbox. 😅

i always wondered this myself. thank you 😝

I love how Scott explained how pressure work and why they are needed before answering the question

@10:27, I get the feeling that someone tried to argue with Scott about how much duct tape would be needed; so Scott did the math, proved them wrong, then flipped them off. :)

Maaaan that's a freaking awesome show, hyped for season 3

The subject of this video was just too good not to click on. Thank you!!

I was a hysterical mess during that entire scene. I knew they weren't going to make it yet held out hope when they made it back to the module. I needed a drink afterwards.

Scott: “I’m not gonna tell you who was wearing the duct tapes.” Gordo and Trace enter.

"Times of useful consciousness" should be posted in every frat house.

This sounds like a Mythbusters episode.

but wait scott, when they used it in apollo 13, they were essentially taping up an airduct for the co2 scrubbing canisters, in that application it was duct tape

For All Mankind is such an underrated show. One of my favorites at this point. It might be worth remembering that they were holding their breath during this sequence; the masks weren't oxygen masks.

very informatice graphs. always wondered about scuba diving oxygen limits and the like.

I haven't even started watching that show, and I enjoyed the science in this vid!

Fantastic video again Scott loved the stuff on positive pressure breathing (sounds horrible). One of the best talks I've ever seen on KZfaq.

"You can drive a car with your feet if you want to. That don't make it a good idea." Chris Rock

Interesting. Thank you Scott

Incredible.... You and Mythbusters with that Duct Tape.... lol. Thanks Scott.
