It just struck me that almost none of the mechanics of these diapers rely on gravity, meaning that no matter what the position of the baby (laying down, on an angle) the diaper will be equally effective.

I used to work on diaper machines and what you said at the end is so true. I was amazed at how fast these machines would run. We were a smaller company and the machines ran at 650 dpm. Even at that speed it's was really something to watch. Everything had to be synced up perfectly for the machine to operate properly. One of the most interesting parts of the machine was the vision system which would reject any diaper was out of spec while running at full speed.

Hi, may I know the origin/supplier of those equipment?

I'd wager many of those clever engineering solutions are the reason they've become so disposable, through being so efficient to manufacture.

I went in thinking 'what could possibly be that interesting about a diaper?' and now I'm completely blown away by materials science and need to learn more! Great job as always!

You know, as a first time father (7 month old child), I have wondered just how the basis of disposable diapers worked. I knew it had to be something far more than meets the eye. Now I know, thank you.

I am impressed that at only 7 months old you are already a father. 😆

I have been working in this industry for over 30 years so I do get to see the machines that make diapers and similar disposable products every day. When I started, 400 products per minute was considered fast and everything was driven by a lineshaft and belts. Now it's hundreds of servo motors synchronized together with incredible precision and well over 1000 products per minute is a reality. Thanks for explaining the product so well, we do kind of take all this for granted but there is quite a bit of engineering that goes into it!

I just discovered Bill and his channel. I could listen to him talk all day. Great voice and presentation.

This is an excellent video to illustrate the internal dynamics of scientific engineering that goes into something as simple as a diaper. Furthermore, it can either prove or disprove claims made in advertising, so in essence, Bill proved that super absorbent diapers actually work. It's the 'how' though, that to me as well, is super fascinating. If I had gone into chemistry when I was younger, I sure wish I would have had Bill as a teacher.

I love how passionate this guy is about any engineering advancement. We could make a device to better fling shit at a wall, and Engineer Guy would love it as long as it was engineered well. That's the kind of spirit and wonder we need to teach children. Keep making these awesome videos!

not planning to have a kid in the near future, but I really love the engineering principle behind it!

I've worn adult diapers for over 20 years since two strokes left me partially incontinent. The ones I use don't have the plastic outer barrier, but they work the same as a toddler's pull-ups. Thankfully I have not had to test their capacity!

The only man who can make diaper engineering sound interesting, love this channel

Wow...I have seen possibly all of your videos and enjoyed all of them. But I thought this one would be different. I was wrong...I am surprised at how fascinating a diaper is.

I am not an engineer, but you make me want to be one. Thank you for the informative video.

I'm a UIUC engineering alumnus and these videos make me very proud. Always incredibly informative and the production is airtight. Thanks to Bill and your team!

This video should be an example of how concepts should be explained, perfectly done. Excellent work. Thanks for the details.

The engineering in this invention is INCREDIBLE. God bless you, Bill, and thank you for all your hard work and effort. Matthew.

I clicked on this video thinking it would be boring, but boy was I wrong. I had no idea that something as common as a diaper had such fascinating engineering. Excellent video as always.

Though I'd have to refute the alien statement. I think it's perfectly possible that the creation of these complex devices came to be. A need arose, demand was high, great minds created ideas and collected and a product that we use now was developed over time. A new ideas continue to come. Or are you reffering to something else entirely that I've misunderstood?

Beautiful explanation of such an important modern technology. Love you Bill!

as the daddy of a nine month old baby boy this is very interesting and I am glad that I can buy them and get the benefit of their creation. I can still see my own mom washing cotton nappies by the dozen and drying them on a line outside in the air. hard work and a lot of waste water, heat, detergent etc.. but still, over four million nappies a day disposed of in the UK makes me wonder about the effect of this manufacturing process and their disposal. either way, hats off to the people who made this possible. necessity being the mother of invention and all that.....

Well Bill thank you very much for making this informative video. I used to work for Paragon Trade Brands years ago as a machine operator who made these diapers and I'm still fascinated by the production process as I never never operated any machine like it since.

Pro tip : you can use diapers to help a wound to stop bleeding. The inner 2 layers do a great job of promoting coagulation.

Your videos are absolutely great. Originally had no interest in the subject and stumbled across the videos. Love the way you present your subject. Would love to see similar videos about electrical parts as its my trade.

Always a wonderful lecture

The top layer resisting water transfer is why nappies are not very good at mopping up spills. When wiped across a spill the nappy will take some of the liquid, but leave behind many trails of liquid. To absorb all the liquid in a spill one is required to press down firmly on the spill, but this risks pushing out the absorbed liquid in when there is excess, and is inefficient when compared to something like a paper towel. Nappies will not float on water if placed inner side down (which is difficult), when tried then it will absorb fluid from the sides and then become full and sink. Nappies however do not leak from the sides unless it becomes full.

Very good and important information shared. Thank you.

Great video, as always. Thank you

Hello, Glad so see two new videos back to back. I wish you would have touched on the negative environmental impacts of so many plastic diapers. They are definitely cool tech though.

Hi there

Amazing explanation.

I've seen how they are made and it's very impressive. The machine might be 60 feet long with dozens of rolls of different materials feeding it, which will automatically switch to feed from full rolls when one gets low. The synchronization of all these rollers and the many conveyor belts is astounding! And it has to handle very thin and light materials which I think is much harder than heavy stuff. They use a lot of vacuum to hold and transfer layers and sheets. Parts are diecut from sheet and the waste is sucked away with one vacuum while another holds the desired part in place. And it's almost too fast to see!

Wonderful as always

Im a new parent and for the past 6 months Ive used those exact diapers and at more than one occasion I thought about how amazing those things are, they really do hold so much liquid, yet keep the baby dry at the same time. Its so ingeniously designed and so much thought went in yet a single diaper costs almost nothing and we use and dispose thousands of them without giving any thought.

Amazing reaction of those polymeres indeed! wonder how many out there know about it! :) Thanks for this channel!

That was an awesome explanation
