I have my first check in and cleaning in 3 years coming up as, well, I hadn’t been able to get healthcare that has dental first, second, I was on a 8 year heroin run.. Have 18 months clean now and figure it’s time to deal with some of this lost a couple teeth and probably need 3 root canals. I’m glad you’re enthusiastic about your work/profession because, it helps me to hear just that even if the dentist or, probably dental students where I have to go, will judge me in some way, they are still doing something that most are not just in by chance or money.

I went into the world of adhesives for a large project at work a couple years ago. The amount of engineering (and just general testing) in it is crazy. I mainly focused on epoxies and their adhesion to between dissimilar materials. It's crazy how many factors come into play - surface area, temperature, surface smoothness/roughness (laser ablation!), curing conditions.. the list goes on..
Indeed: It is amazing complex. It reminds me of how metallurgy used to be described: one third science, one third engineering, and one third black magic.

I’ve rewatched the aluminum can video so many times, I’m glad you’re still doing this. These calm explanations give me such joy to listen to and watch. So once again, thank you very much.
This is one of the best educational videos I've ever seen from a script, format, and photographical perspective, like an 11 out of 10. Visually it perfectly illustrates the mechanical qualities of the materials in an extremely simplified breakdown for the fundamental concepts and saves the additional complexity towards the end of the video in natural progression. The reading is clearly spoken, paced appropriately for comprehension and when showing examples. No bloat, no gimmicky attention grabbing, no sponsor for a specific brand of tape or unrelated service (although a sponsor would be fine for a channel with such great production). Clicked because I had been subscribed and was mildly interested in duct tape, but post-watching I wanted to share my appreciation for the work put into this and am more intrigued by my well improved understanding of a mundane material. Please keep up the good work!
"don't use it on a duct" is very true. Once we tried to fix a temporary air bag duct as it eventually disintegrated in in use with duct tape and the tape held even less than the bag when air was pushed through with enough force. Constant motion from turbulent air just detached the tape and small dust particles in air made sure lost stickiness.
Thanks for adding the important note of NOT using it for ducts! Our builder used it to hold together the dryer vent pipes inside the wall and I found out years later because it ended up melting and the vent pipes separated. So the dryer was venting inside the wall for years! When I opened up the wall I found mold and years of lint!
There is special metallic tape for ducts...up to 350*C, and even other types of tape that can handle 500-600*C, for a chimney or something. Price is also special XD
And here I was thinking the warning to not use it on ducts was to avoid liability if it were used to repair something that carries noxious fumes, and it failing and leaking resulted in death or injury.
This man explains things so simply a child could understand without talking down to the audience. He remains captivating without jump cuts, camera shake, wild graphics, or flashing colors.
Peeling is interesting from an engineering perspective. The hold of the glue can be considered in terms of required force per unit of area - a bigger contact area of tape can resist more force. But when peeling, most of the adhesive is bearing no load, the entire load is applied to a line. Theoretically a line has zero area, so the effective force per area while peeling is infinite. No wonder the adhesive fails
I remember a few years ago in English classes at my University (I'm Polish) the teacher asked us to watch your video on injection molding- when I googled the title I shouted "The Engineering Guy! I love his videos!". You make me proud to be an engineer and I'm so glad I pursued this carrier. Thank you and keep them coming!

I love your presentation style. I dont mind long videos so much but its refreshing to have information presented in a reasonable time frame and it probably take a bit of effort to prepare everything in advance
I remember back when I was in high school watching these videos in awe and thought they were excellent material. Fast-forward a few years later, I’m attending UIUC as an engineering student and I ran across you on one of the bus lines. Forever grateful for that conversation we had, and glad you’re making more videos again!
@@Cssfiend duck tape got its name because water rolls off the tape, like off a duck. The tape was developed to waterproof ammo boxes. The mother of a son fighting in the jungles of the Pacific theater wrote the President. For whatever reason he choose to take up the banner for her. By all accounts everyone loved the tape.
@@Cssfiend At 10:22 the roll he's using clearly says "Duct tape". No idea what the original name was, but duct is not a misnomer if it's on the product.
The complexity and innovation behind a seemingly simple product like duct tape is truly fascinating, especially the science and engineering behind getting the stickiness just right.
This channel has been an integral part of my childhood! It’s sad to see you grow old but the fact that you keep us engaged and ever curious to learn something new is just amazing. It might sound like a bold claim but what you are doing is nothing less than a service to humanity. ❤
Most people take Duct Tape for granted and often make fun of people who use it with comments like "Held together with duct tape". It's amazing to see how much engineering went into the product and this explains why it works so well in so many applications. Thanks for making this video.
I was sure that you were going to mention that Duct Tape was originally referred to as Duck Tape, as duck is the name for the cloth layer used to reinforce the tape. This is why it's not meant to be used on actual ducts. It's just that cloth is no longer referred to as duck, so people called it duct, as it is something that they are more familiar with.
I believe that historically, the tape was invented by ducks and used to tape their eggs together so they didn't roll away. But after the ducks sold the rights to 3M, people started calling it "duct tape," because "duct" is the past tense of "duck."
How interesting! I do a bit of sewing and there is definitely still fabric out there called duck, but as you said it's not a general name for fabric anymore. For those interested, it's a type of hard-wearing cotton fabric, like denim but thinner and floppier. You'd probably make something like kids' overalls out of it. Fairly easy to find. But most people wouldn't know about it since it's not widely used. The weave is much tighter than the loose weave on the fabric in the tape shown in the video!
I can't describe how much I enjoyed this video, watching your videos in my childhood is one of the main reasons I decided to study Mechanical engineering!
What I love about this channel is that you learn so much about common things that seem so simple and sometimes irrelevant. It is a great illustration of how important attention to detail really is.
This channel was one of my inspirations to pursue a career in engineering. Dating back to junior high. Just graduated from electrical engineering and working as an eit where i interned in the ic industry! Convocation at the end of may. Your channel rocks, release more videos!
Another masterpiece as usual, Bill. I contrast it with last night's episode of Nova. Your video was calm, focused, and effectively communicated new (to me) information. The Nova episode was boisterous, changed their interviewee every two sentences, and didn't introduce me to a single new piece of information. Thanks for your excellent work!
Amazing. I would never have thought that something that I take for granted and use everywhere would have so much engineering effort put into it. This certainly gives me a new appreciation for duct tape that I otherwise never would have had till I watched this Ductapementary.
I feel an utmost sense of joy when watching your videos. The script and visualization is perfect; nothing to add and nothing to take away. Thank you Engineer Guy!
So great to see you back making videos. You've clearly inspired many, many people with your content - I personally know an engineer who made his career choice thanks to your work.
Great, clearly explained video as always! 1 question is not answered: Why is it called Duct-Tape if it is not supposed to be used on Ducting 😅 I've always learned is was invented for use on air ducting.
The original term was duck tape, named after the type of fabric used in the backing, duck. People switched to calling it duct tape, possibly because not many people know what duck fabric is.
It's named after a kind of fabric - en.wikipedia.org/wiki/Cotton_duck Of course, people have long since forgotten this meaning, and at some point, people felt that "duck tape" is a mispronunciation (or mistype) of "duct tape", which sounds more reasonable if you don't know what duck cloth is (helped by the fact that people did actually start using it on air ducts, and the marketing quickly switched to a shiny grey finish to look like a duct :D ). Which itself gets hilarious when people then go the other way, and even weirder, when a US company actually manages to call their "duct tape" product "Duck Tape" and register that as a trademark. Which is legal because the original common name has "fallen out of use". And now you can't call duck tape duck tape anymore, because now it's a brand product, not a common name.
@@figmentpez Thanks for the rabbit hole you just sent me down 😆. So, from what I read, it's one of two things: either the early versions made by J&J did use duck fabric, as you said (which I just learned was an actual thing), or it was because the soldiers in WW2 referred to it as "duck" tape because of how water rolled off it like a duck's hydrophobic feathers.
@@LuaanTi Funny that it comes from the dutch word "Doek" Which means Cloth. And it is indeed Cloth-tape. Which makes sense... Coincidence is that i am dutch 😅
It's wonderful to see another video from you. I remember watching your video on drink cans years ago, and now I've just graduated with a degree in mechanical engineering, about to start a job in systems and automation. Thank you for your inspiration!
In a world of science denial, conspiracies, and glorification of ignorance, Bill's simple explanations showing the genius of human engineering for even the most simple of objects is both refreshing, and a strong counterargument to those who deny everything. Thank you Bill.
I'm so thrilled that we finally have another installment in The Engineering Of series! As a casual science/tech enthusiast, your channel has easily been among my favorite sources of extremely informative and adeptly written videos. Your production feels right at home for someone like me who grew up watching the Science/Discovery/History channels, but you manage to create far more concise and information-dense content. I hope we can look forward to more from you in the not so distant future!
If this is the bougie tape connoisseur sub thread then for the regular class of duct tape my vote is for Nashua. Of course if you need the high performance then step up to the 3m or Berry. Then of course we have to talk gaffers tape. And don't forget aluminum tape for actual ducts.
It was great to see you back! I worked in an industry that relied heavily on duct tape. Over 30 years of being around the stuff, I can say that not all duct tapes are created equal. I used to have a good collection of various colors and manufacturers tapes. Unfortunately, my kids discovered that you could make things out of the stuff. Oh well, what else was I going to do with all that tape? Great video!

You are truly leaving a legacy here. These are the kinds of videos that inspire children and shape their lives. Not a single unnecessary word!
Yeah, I'm tired of everyone welcoming me to the video, to the channel, leave a like, subscribe.... none of that. It's awesome.
Still one of the best RUclips channels ever!
I love your presentation style. I dont mind long videos so much but its refreshing to have information presented in a reasonable time frame and it probably take a bit of effort to prepare everything in advance
I remember back when I was in high school watching these videos in awe and thought they were excellent material. Fast-forward a few years later, I’m attending UIUC as an engineering student and I ran across you on one of the bus lines. Forever grateful for that conversation we had, and glad you’re making more videos again!
"Don't use duct tape on a duct"
Didn't know Bill could be so funny
Don't use it on a Duck.... They get mad.
@@bdsoftley4079 Incidentally, it's quite surprising the number of people who do mistakenly call it duck tape.
@@fredbloggs8072 duck tape is its real name, duct tape is the misnomer, duck or ducking is the name of the original cloth used to make duck tape
@@Cssfiend duck tape got its name because water rolls off the tape, like off a duck. The tape was developed to waterproof ammo boxes. The mother of a son fighting in the jungles of the Pacific theater wrote the President. For whatever reason he choose to take up the banner for her. By all accounts everyone loved the tape.
@@Cssfiend At 10:22 the roll he's using clearly says "Duct tape". No idea what the original name was, but duct is not a misnomer if it's on the product.
Masterfully put together. And I’m not just talking about the duct tape.
Thank you.
he's talking about the fit 🥵🥶
The complexity and innovation behind a seemingly simple product like duct tape is truly fascinating, especially the science and engineering behind getting the stickiness just right.
This guy has one of the most relaxing voices ever. I think I’m gonna loop these videos when I go to sleep!
I hope you were a teacher in a past life man, your explanations are so clear and concise!!
I am still currently a teacher!
@@engineerguyvideo glad to hear it and wish I was in one of your classes! Thanks for teaching the masses on RUclips!!
@@engineerguyvideo
So happy for your lucky students.
Your kind voice is a gift. Please keep giving.
Reincarnation is false

Brett never got the memo.
Have a great Tuesday!
Welcome back Bill. Great to see you
You're one of those channels that I don't realize I've been dearly missing until you post something after a long pause.
This channel has been an integral part of my childhood! It’s sad to see you grow old but the fact that you keep us engaged and ever curious to learn something new is just amazing. It might sound like a bold claim but what you are doing is nothing less than a service to humanity. ❤
Thank you for the kind words. I would note that the alternative to growing old is worse.
I'm a physicist and now I respect engineers more. Thank you!
Most people take Duct Tape for granted and often make fun of people who use it with comments like "Held together with duct tape". It's amazing to see how much engineering went into the product and this explains why it works so well in so many applications. Thanks for making this video.
It's not important what anything is held together with, just that it stays together.
I was sure that you were going to mention that Duct Tape was originally referred to as Duck Tape, as duck is the name for the cloth layer used to reinforce the tape. This is why it's not meant to be used on actual ducts. It's just that cloth is no longer referred to as duck, so people called it duct, as it is something that they are more familiar with.
I believe that historically, the tape was invented by ducks and used to tape their eggs together so they didn't roll away. But after the ducks sold the rights to 3M, people started calling it "duct tape," because "duct" is the past tense of "duck."
I was surprised that he falsely claimed that it was invented in WWII
The History Guy did a great video about the history of Duct v Duck tape
Yeah it's definitely DUCK tape, and you know it's not DUCT tape because you specifically aren't supposed to use it in ducts!
How interesting! I do a bit of sewing and there is definitely still fabric out there called duck, but as you said it's not a general name for fabric anymore.
For those interested, it's a type of hard-wearing cotton fabric, like denim but thinner and floppier. You'd probably make something like kids' overalls out of it. Fairly easy to find. But most people wouldn't know about it since it's not widely used. The weave is much tighter than the loose weave on the fabric in the tape shown in the video!
This video has very strong "class, we're just watching a film today"-film-energy
And I love it
Thank you for spending 10-20 minutes of your time to make this video. 😊
You are welcome.
This definitely took way longer than 20 minutes to prepare
Thank you for your videos Bill, your explanation is very easy to follow and understand even for a complete layman in engineering.
So glad you have returned to make us all more enlightened.
We missed you.
We wait for years, but we are always glad when you post
So happy to see this pop up on my feed. Made my day and my son is now rewatching all the older videos. Hope this is the (re)start of more to come.
I can't describe how much I enjoyed this video, watching your videos in my childhood is one of the main reasons I decided to study Mechanical engineering!
I knew as soon as I clicked on this video that I was about to watch the whole thing. It's composed straightforwardly and entreatingly. Subbed!
Wonderful to have you as a subscriber.
What I love about this channel is that you learn so much about common things that seem so simple and sometimes irrelevant. It is a great illustration of how important attention to detail really is.
waiting for 1 year about a video on duct tape and its 100% worth it
Wonderful to see you again Bill!
Adhesives are a fascinating topic that so many of us take for granted, and you broke it down beautifully as usual! ✨
This channel was one of my inspirations to pursue a career in engineering. Dating back to junior high.
Just graduated from electrical engineering and working as an eit where i interned in the ic industry! Convocation at the end of may.
Your channel rocks, release more videos!
Another masterpiece as usual, Bill. I contrast it with last night's episode of Nova. Your video was calm, focused, and effectively communicated new (to me) information. The Nova episode was boisterous, changed their interviewee every two sentences, and didn't introduce me to a single new piece of information. Thanks for your excellent work!
I missed you and these videos so much. It’s the ultimate comfort content for me. Glad to see you. Hope you’re doing good
What's next, PhotonicInduction? Love seeing a new video here!
Agreed!
Question, what's the name of your channel? lol
@@zackl3094 I have to admit, I was only aware of the Geerling Engineering channel until yesterday.
Are you guys gonna advertise Bitcoin scams or something?
@@BichaelStevens Agreed. Jeff is such a shill. His dad's channel is better.
@@BichaelStevens Was funnier the first time watching it..... No, not Bitcoin or a scam.

I love your books! I've got three of them. Thanks for taking the time to still do these video sporadically.
Amazing. I would never have thought that something that I take for granted and use everywhere would have so much engineering effort put into it.
This certainly gives me a new appreciation for duct tape that I otherwise never would have had till I watched this Ductapementary.
I feel an utmost sense of joy when watching your videos.
The script and visualization is perfect; nothing to add and nothing to take away.
Thank you Engineer Guy!
"Utmost joy?" You must have a very limited emotional range.
@@johnsmith1474 profoundly limited. This short interaction with you has made my day.
Glad to have you back, Bill
⚠️ This is not a drill. I repeat: This is NOT a drill! *engineerguy* HAS, in fact, uploaded a new video! ⚠️
Not only that... but a video on possibly the most important human invention since the wheel!
This is NOT a drill, tell ur mom to GET on the dance floor @whatphoto
@@TonyRulelathe is far more important.
this is not a drill. this is duck tape
@@XxIcedecknightxXthis, too, is not a drill, though it can be used as one.
00:13 "temporarily":)
I love this guys content. His passion and clarity is so refreshing. Like a cold glass of water on a hot day when you’re thirsty.
I have no idea why this showed up in my feed, but I'm so glad it did!!
Engineer Guy uploads a Video: I have a good day.
I don't think I've ever clicked on a recommendation so quickly and with such glee!
Engineer Guy uploads a video about the most important invention in the history of "cobbling things together"... I have a most excellent day.
I did not know 15 minutes ago, that i needed this information. Now i can't fathom how i lived 53 years without knowing.
Perfect timing. I was just about to eat lunch. I know what will be my lunchtime entertainment today!
So great to see you back making videos. You've clearly inspired many, many people with your content - I personally know an engineer who made his career choice thanks to your work.
Excellent, clearly explained and enjoyable excursion through the sticky business of understanding the everyday.. Thank you.
Good to see you back!
Great, clearly explained video as always!
1 question is not answered: Why is it called Duct-Tape if it is not supposed to be used on Ducting 😅 I've always learned is was invented for use on air ducting.
I could not get a clear answers on this, other at the kind of urban legend level.
The original term was duck tape, named after the type of fabric used in the backing, duck. People switched to calling it duct tape, possibly because not many people know what duck fabric is.
It's named after a kind of fabric - en.wikipedia.org/wiki/Cotton_duck
Of course, people have long since forgotten this meaning, and at some point, people felt that "duck tape" is a mispronunciation (or mistype) of "duct tape", which sounds more reasonable if you don't know what duck cloth is (helped by the fact that people did actually start using it on air ducts, and the marketing quickly switched to a shiny grey finish to look like a duct :D ). Which itself gets hilarious when people then go the other way, and even weirder, when a US company actually manages to call their "duct tape" product "Duck Tape" and register that as a trademark. Which is legal because the original common name has "fallen out of use". And now you can't call duck tape duck tape anymore, because now it's a brand product, not a common name.
@@figmentpez Thanks for the rabbit hole you just sent me down 😆. So, from what I read, it's one of two things: either the early versions made by J&J did use duck fabric, as you said (which I just learned was an actual thing), or it was because the soldiers in WW2 referred to it as "duck" tape because of how water rolled off it like a duck's hydrophobic feathers.
@@LuaanTi Funny that it comes from the dutch word "Doek" Which means Cloth. And it is indeed Cloth-tape. Which makes sense...
Coincidence is that i am dutch 😅
Missed you bill
It's wonderful to see another video from you. I remember watching your video on drink cans years ago, and now I've just graduated with a degree in mechanical engineering, about to start a job in systems and automation. Thank you for your inspiration!
I love your visual way of explaining a concept together with the top tier flow of the script!
10:26 so "duct tape" is a misnomer?!
THE MAN, THE MYTH, THE ENGINEER, THE LEGEND.
How I've been waiting for your return.
In a world of science denial, conspiracies, and glorification of ignorance, Bill's simple explanations showing the genius of human engineering for even the most simple of objects is both refreshing, and a strong counterargument to those who deny everything. Thank you Bill.
I'm so thrilled that we finally have another installment in The Engineering Of series! As a casual science/tech enthusiast, your channel has easily been among my favorite sources of extremely informative and adeptly written videos. Your production feels right at home for someone like me who grew up watching the Science/Discovery/History channels, but you manage to create far more concise and information-dense content. I hope we can look forward to more from you in the not so distant future!
I'm SO GLAD YOU'RE BACK!!!!!
10min of a man talking about duct tape....And its amazing.❤
Shoutout to project farm for helping me buy the best duct tape out there, T-rex tape.
We're gonna test that!
I fixed a leaking water pipe with it 3 years ago, it's still there and not leaked. T-rex is awesome.
If this is the bougie tape connoisseur sub thread then for the regular class of duct tape my vote is for Nashua. Of course if you need the high performance then step up to the 3m or Berry. Then of course we have to talk gaffers tape. And don't forget aluminum tape for actual ducts.
"Don't use duct tape on a duct".
Thank you for a brilliant informative presentation with no mad music and no fast forwarding. I am enlightened.
So absurdly fascinating.
You make me feel like a kid again, watching the Science Channel.
Dude. This is awesome! Keep up the amazing work!
Next up, the engineering of WD40
Christmas came early!
Not going to lie, I thought its initial purpose was for air ducts
It was great to see you back! I worked in an industry that relied heavily on duct tape. Over 30 years of being around the stuff, I can say that not all duct tapes are created equal. I used to have a good collection of various colors and manufacturers tapes. Unfortunately, my kids discovered that you could make things out of the stuff. Oh well, what else was I going to do with all that tape? Great video!
Love these videos so much. Taking the everyday and proceeding to do a deep dive on it magnifies my appreciation.
