Dude this guy made something that's normally really boring into a really fascinating and enjoyable video to watch. Never thought I'd enjoy a 12 minute long video about cans.

It’s easy to forget how well engineered even the most simple things in our day to day life really are.

I love educational videos like this. No NordVPN sponsorship, no random "funny" videos or stock images that interrupt the flow, no "upbeat" music to distract from what he's saying, just a great, informative lecture. Keep at Bill!

The engineers had to overcome many challenges over the decades to give us this outstanding design. Fortunately they maintained a can do attitude.

I want this guy as my physics/engineering teacher. He breaks it all down to easy to understand segments, and explains it all beautifully. A+

I'm not lying, and I can't be the only one like this, I've watched this at least 50 times simply because I enjoy watching it and listening to this man explain how aluminum cans are made.

Wow, I am impressed by the level of detail that goes into can manufacturing

This is probably the most interesting video about a thing I wouldn't expect myself to be interested in. I love the speech cadance. If more professional educators (a.k.a. teachers) were like this, the world would be a better place. Thank you for a great video Bill, I'm looking forward to exploring more!

I remember as a child when you had to have a can opener to open a soda can, or a beer can. Then came the pull off tab. And then the tab we use now. Great video. Explains things very well. Now I understand how the can keeps it seal.

8:43 I remember large cans (upwards of 40 or even 64oz) containing milk or hawaiian punch. This was before those 64 oz (later 2L) plastic bottles appeared. Those had to be opened with that triangular punch tool as shown. I remember seeing lots of pull tabs out in city parks, those things were blight. The stay-on-can openers started around 1980. The big cans still exist but are niche now.

You know you're a good teacher when you can make something as seemingly mundane as the aluminum can into one of the more captivating videos I've ever seen. Almost everybody, including I would say most instructors, struggle to keep explanations in layman's terms without dumbing it down, as almost none of us speak the internal language of whatever industry is presented.

Absolutely a design masterpiece. The opener alone is close to brilliant. I’m old enough to remember the pull tabs that littered beaches and wooded areas that cut feet and were a health hazard. The opener that doesn’t detach unless with concerted effort is by itself is fantastic. And it turns to allows a straw to fit! It’s a miracle of engineering.

I remember an interview with the guy who holds the patent for the can’s inner lining that helps it resist acidic corrosion. He stated that he would never eat or drink from a can because of the materials in the lining needed to resist this corrosion for weeks, months, or even years.

I am old enough to remember when the ring pulls were standard. They came in two varieties, at least in the UK - one with the little flanges for leverage either side of the rivet - as shown herer - and one without. The former were always more popular: after pulling them off the can, the ring could be broken from the tab, and then you had a great little toy. The tab was a spring, and the ring was a miniature frisbee which could be launched by fitting one end of it in one of the slots between a lever flange and the rivet, pulling it back and releasing it. I get that the tabs are a better design, but they are a lot less fun.

*This is probably the most perfectly presented talk on all of CZstate.* 👍

His calm enthusiasm coupled with the knowledge of the process in creating the aluminum can is what makes this so interesting.

I really enjoyed this a lot more than I thought I was going to. Absolutely loved it. Cannot wait for the next one

Very well presented video. No filler info. Everything I would want to know about aluminum cans. Love this type of video. You nailed it! And gained a subscriber. Looking forward to other videos you have that are hopefully like this.

I love how he goes step by step and explains every little detail without fail he is such a great teacher

I've been using cans for 50 years and never thought about it. After this video I have great respect for a simple can.Thank you. ❤️ Regards from 🇩🇪

What a video. No clickbait, no sponsors, nothing. You got to the point straight away. Very informative, quality video. 10/10 would watch again. Brilliant 👍

You made something so mundane into an extremely interesting explanation. No small task in today's world of nanosecond attention spans. Congratulations on creating an outstanding video!

Great video! I'm so dang old, I remember every generation of beverage can demonstrated here, including the flat top that required the use of a can opener. And, there were mostly aluminum cans that had a steel seam. PSAs of the day for recycling included this distinction of a seamless side, as the seamed ones were not considered (as easily) recyclable and had to be dealt with separately. You missed a chance to throw in a few seconds of Jimmy Buffett when describing the early pop-tops. But, I guess that wouldn't fit your format very well, heh. The pull tabs were sometimes linked together by hand to make a useless chain, or collected in a container, as ways to avoid just tossing them carelessly. The glass deposit bottle was so much better than aluminum in so many ways. Sad that in most places they're no longer used. Even the uncommon glass bottles are not deposit bottles in most places now. I used to make pocket money when I was a kid, by scouring the roadside for deposit bottles. At 5¢ a pop, I could buy a large soda AND a small bag of chips for five returned bottles, plus one for the deposit. But, no doubt the aluminum can is cheaper to ship.

Explained well and in an engaging way. It's hard to find a video like this that explains concepts in a way that you could show to cub scouts or young children in schools without boring them. Bill gives just enough detail spreads out with diagrams and animations to keep the interest. I didn't even realize the video was nearly over until I saw the first bench on the right side of the screen.

The lever is absolutely ingenious! It took me a while to understand the implications but oh once I did it made so much sense! The fact that you're essentially opening the can not by pressing in the tab but by drawing out the pin getting help from the pressure to shear an opening that lets out the pressure and then you push the metal tab in, is an absolutely amazing engineering solution and I have never realized it!

Welcome back! This was fascinating, thank you :-)

That was great! Thank you. I was amazed by the lid sealing and the opening tab. Never knew that was a river that depressurized the can!

The double seal was invented by 'mechanical' workers in Pittsburgh for sealing duct-work for heating and air conditioning and is called a Pittsburgh bend. They are hard to make by hand, but in the olden days that's what you did. I have a can 'seamer' made for #10 cans that applies the same bend with 2 actions, a push and a pull.

I was really surprised that he left out one of the most impressive engineering aspects of the can - when you leave the can in extreme temperatures, e.g. the freezer, the top and the bottom are designed to expand (bulge outward) so that the can doesn’t just explode. This is another reason for making the can cylindrical - so that it’s easier to direct that extra pressure into a specific direction (into the top or bottom of the can, i.e. if the can were spherical, the extra pressure would expand the can in all directions).

Wow, I'm impressed. Aside from the content, which is very interesting, the absolute precision of Bill's word choice and arrangement is so impressive. I'm technical, and I strive to describe technical subjects - precisely. I do not pretend to have the mastery of presentation Bill has, but I recognize it.

He explains it pretty clearly, because he can.

Excellent job! This was really well made and I loved it!

I love the way you explain this subject!! Clear and well illustrated, and give us another resources ! Thanks for sharing this ! new subscriber here

Its amazing how complicated everything is made in a factory yet it's just a simple item

It's truly amazing. You watch this video, and marvel at how ingenious some features of our world are. You think of the sustained intelligent effort that has been invested to reach the present economic efficiency, and state of the art technology in carbonated beverage containers. And then you pick up the newspaper - or watch television - and you see various elements of the US Federal Government at work. Do you wonder, as I do, how a society capable of such engineering and efficiency in beverage cans come to be governed by lame stooges with Joe Biden as the leader?

I like to imagine this guy lives in a parallel universe, surrounded by tables and cans, and nothing else exists except an eternity for him to learn everything about aluminum cans

One of the most amazing youtube videos ever - informative without being cliche or clickbait. Watched this with the children so thank you.

Enjoyed all the visual representations and diagrams/videos. Kept me stimulated and engaged while constantly providing high value information. Unlike modern videos where it's just someone talking to the camera the entire time with tons of filler. Thank you Bill

It’s surprising what we take for granted. The science, engineering and thought that goes into a simpler can 👍

Over the years I keep coming back randomly to enjoy this dude's amazing video. He's made entertainment out of mundane. Thank you, engineerguy.

Amazing. I never knew how incredibly ingenious and complicated our modern cans were. This wasn't just informative, but fun, thank you.

Amazing, i never watched such scientifical approach to the such domestical things been shown in a CZstate videos. Thank you for your efforts, it's was please to look at all the explanations and listen to them.

In my opinion, science and engineering are two of the best fields. They're both so fascinating.

Absolutely fascinating. The thing that is missing is the iconic shape of a certain cola.

Bill, what a great video. Being in the can making industry, I could see the immense value your presentation could have on training new hires for our facility in the basic concepts of can making. Would I be able to use this video for training purposes?

I never thought I'd watch eleven minutes of someone talking about cans. Incredibly informative and exceptionally well presented! Thank you!

I’ll admit I’ve always been a bit curious how the tabs on soda cans work. Cool video.

Dude! you almost produced the full perfect explaination of how a modern beverage can is made and works...! You forgot to explain the part on "how they etch the lid opening" for the pealing of the metal and how it is achieved with such consistency and precision!

Great work Bill. Solid and briefed explanation of a daily marvel we take for granted...

This was the best , clearest most interesting lecture I can ever recall hearing ,flawlessly delivered ,

I want a ball can now I don’t care if it rolls

Love the way he explains things. I wish my college professors were like him. I would have actually learned something useful!

I actually spent 11 minutes watching something that I've always wanted to know as a kid. Thank you for educating me. This is a lot better that the stupid animated ones they showed you back in school

Thank you, Sir. I have pondered how they make aluminum cans for years, probably decades. Bravo!

Thanks for this great video. I have a question. Has there ever been any concern with the hygiene of the stay-on cap? It pushes a part of the external side of the can into the beverage. Yes, we can wipe a can clean, but not all toxins/bacteria are visible.

His clarity and inflection are easy on the ear, pleasing and interesting. He is direct and efficient. Excellent all around.

Thank you for making a wonderful video about something no one's ever asked about. It's truly a fascinating process and something I've never actually asked myself about.

Soemthing I never really thought of (until I visited Colorado) was pressure. I often have noticed that their condiment containers always have more pressure in them, like they’re going to pop. So it’s interesting to me to know that cans can purposefully withstand normal atmospheric pressures.

I seem to recall (from college 30 years ago...) that the material properties are very important also carefully chosen such that it is ductile during rapid deformation while otherwise fully hardened. Pretty amazing process engineering!

This video was recommended to me multiple times, but each time I thought I'll watch later. And now, I'm regretting why didn't I watch it earlier. So well made and explained. It is a masterpiece, and a treat to watch.

I watch this every few years and enjoy it like the first watch. This and the injection molding video are peak YT. Bill's a fantastic lecturer.

Way to make a subject that, even though is interesting it's hard to explain without boring the audience, into a very engaging and entertaining video!

Thank you! Never knew this is how cans were made before. Amazing video to watch.

Such simple yet precise animations! What a delight

Being an ex-engineer, I already thought of the modern aluminum can as a marvel of engineering. (I'm the only one I know that would think so) This was a very interesting video, thanks.

Man, this video was 11:00 minutes long. It was also about cans. But man this was an extremely interesting video!!!

This is my first view on your channel and this is an absolutely amazing introduction to the channel! Very cool look at something so common :)

Very cool! Never gave much thought to aluminum cans but the design and manufacturing is impressive!

Ok, this goes in my favourites! That was one *_HELL_* of a great explanation and with some nice visuals at that!

Great vid. Long but never wastes time, efficiently packs so much information in!

This is the way engineering should be taught

Really interesting! It's amazing what people have invented.

That was a great video you did. I knew about them being lined. I melt them for aluminum. I love melting aluminum, but cans aren't my first choice.

This cans ingenious design requires 3 different kinds (alloys) of alluminum also. I worked in an alluminum R&D facility. Alluminum is amazing in so many ways. Particularly the way it itself is made!

I always watch this and the "how to turn a sphere outside-in" video every now and then, is always interesting and entertaining.

I know what I’m going to talk about for 3 hours at my next house party

Amazing video and superb animation. Very clear explanation, I liked this a lot!

I LOVE this video!!! I spent 16 yrs working in this industry and often held peoples attention when I explained what I did for a living. Always thought about the amazing amount of science that went into the profitable production of cans. Yet no one really gives them a thought

Your delivery of the sentence "The term of art in the industry... is DECORATION." is a moment that has inspired me over the years - you have made an extremely straightforward sentence sound unbelievably cool. That moment is the one I remember from this video most.

The seam on the pop lid is finitely accurate I was told. Enough to hold the pressure but able to be separated under the pressure of the leverage. The can design is great, the production line is another level again.
