Could You Make A Space Suit From Duct Tape?

[@TheQuarrion]

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!

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.

[@johnnyc.31]

Yes this! This whole video missed a bunch of major points

[@joshm3484]

would their lungs stay empty? A little air would remain in their lungs when they exhale. Without pressure, would that expand to fill their lungs, like a small bubble deep underwater gets bigger as it rises?

[@Tim-K.]

@@joshm3484I’m no expert, but if there is only a small amount of air, then it could escape without much trouble. Since it takes the way which offers the least resistance and there is not so much air trying to escape all around once. But if there is no other route to the vacuum, which is the case in the show because they have masks (apart from maybe other significant openings of the body, they could maybe suffice), then I don’t know what would happen

You do actually use duct tape to fix ducts. Looks just like duck tape, but better quality. Not to be confused with foil metal tape.

[@kindlin]

@@JoshuaTootell Your phrasing confused me, but yes, metal foil tape is the modern _literal_ duct tape.

[@AntiComposite]

Grey tape will work on ducts, until it fails. Temperature change (like you see on ducts) turns the adhesive brittle and solid, and the coated fabric decays, fairly quickly.

[@SynchronizorVideos]

Din't use the standard fabric-backed grey "duct tape" on your HVAC ducts. It'll work for awhile, but will eventually fail and require you to re-do everything. This is coming from a guy who's spent countless hours under apartment buildings re-assembling dryer vent ducts. What you want to use is metal tape; essentially heavy aluminum foil with a more stable adhesive applied to one side. The truth is that for any given specific application, there's usually a specialized product that will do a better job, and will hold up better long-term. But as a catch-all field expedient tool for temporary or emergency patching or securing tasks, it's hard to beat a roll or two of the classic duct tape.

[@kindlin]

@@AntiComposite I can attest to this. I had a duct _fall off_ the ceiling (the ceiling was open) and land on the ground. I only noticed it 2 months later after the depths of winter had passed, and just couldn't figure out why my room wasn't getting warm.

You don’t need any tape. It wouldn’t do anything.

[@lajoswinkler]

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.

@@Ketothev If memory serves, wasn't that done partially because they wanted to avoid rupturing their lungs?

Yes, they were told to breath out before exiting the airlock, to prevent damaging their lungs. They did not have an oxygen supply.

[@mitchellhood8320]

Wouldn't have done anything anyways. I have a bunch of gas masks and SCBA's and actually own that exact mask as far as I can tell from the video. They use a pair of very thin rubber gaskets to control the air flow for intake and outflow to ensure that air only comes in through the filter and out through the output gasket. Even if the output wasn't designed to dump air out of the mask when there is a pressure differential the input gasket is thin enough it would likely fail with 1 atmosphere of pressure in the mask, on top of temperature stress to it. So the inside of their mask was in vacuum as soon as the decompressed anyways.

[@Sue_Me_Too]

@@mitchellhood8320 Yeah I was thinking that too, the gas mask is designed to let air out not keep it in.

@@S1baar Rapid decreases in pressure while diving can cause decompression sickness. The extra nitrogen that is dissolved into your blood will separate creating air bubbles in your tissue and blood vessels. These bubbles can block blood flow and additionally cause a condition called the "bends" where by the severe agony of bone and joint pain causes you to double over. To put it simply, your body becomes a carbonated drink that just got opened, it's all bubbly and stuff.

[@RCAvhstape]

@@S1baar Ezekiel Jones isn't wrong, but he didn't answer your question: the reason you never hold your breath is because if you have to swim to the surface in an emergency, the air in your lungs will expand as the outside pressure on your body decreases. This will cause your lungs to inflate and will damage the lung tissue. This is called lung expansion injury, and is a whole other thing that can painfully kill you besides the bends.

its still deadly due to our medical science. even at a few seconds the damage done would kill or severely cripple the person. even the more realistic sci fi depications mention you wouldn't want to be deliberately exposed to vacuum unless it was a dire emergency that death would 100% result if you didn't. it would be like jumping out of a the penthouse of a skyscraper versus being burned to death.

[@z-beeblebrox]

@@toomanyaccounts This comment precisely demonstrates the lack of understanding I'm talking about, thank you. It's equivalent to how you can tell people over and over that there's no sound in space but they'll still add sound effects to sci fi movies anyway. And characters will instafreeze or implode or whatever silly thing they think happens when exposed to vacuum.

[@toomanyaccounts]

@@z-beeblebrox well some of those sci fi depictions do mention that the sounds being heard are the computer adding them in so the crew wouldn't get freaked out by ships on the viewscreens exploding without sound or the ship weapons that fire without noise. I remember one rpg sourcebook saying that while laser weapons didn't have sound the manufacturers would add a sound making module with customizable sounds because customers found it disconcerting that the weapons weren't making a noise when fired. .

[@hegeliandetective1034]

@@z-beeblebrox How would you know if there's no sound in space? You haven't gone to space with your ears out in space. When objects hit spacecraft with microphones, you can hear the object hit the outside. If there's a super nova, you think an explosion would have no sound? LOL

[@z-beeblebrox]

@@hegeliandetective1034 It's not a property of "space" it's a property of a vacuum: sound is nothing but how we sense vibrations through a fluid medium. 99% of the time, that medium is Earth's atmosphere, but any medium works. Like eg the metal vibrations on the side of a space ship rippling through the air inside said space ship, or whales singing in the ocean. But all you need to do to prove this fact is create a simple vacuum, go inside it, and you too can experience things not making any sounds. Because obviously - if there's no molecules to vibrate your eardrums, you won't hear anything. It's the sound equivalent of turning off the lights.

[@RamadaArtist]

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.)

[@jacksonledford6874]

In the us it is used for duct work sometimes and the oldest brand is called duck tape

@@RamadaArtist yeah it's not used to seal ducts just everything else. It came from the history of attaching adhesive to sheets of duck cloth, then called duck tape then duct tape then both interchangeably

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.
