That "pull tab," or pop top, made Jimmy Buffett famous. I blew out my flip flop Stepped on a pop top Cut my heel had to cruise on back home But there's booze in the blender And soon it will render That frozen concoction that helps me hang on. steve

holy shit. This guy does an amazing video, and then goes on and gives 37 links to other videos that delve even further and doesn't ask for shit. This is the real MVP my dudes.

What was the process that decided the can's height and diameter? The cans you show dont use the minimum amount of material for the volume - at least for an idealised cylinder. Is there something else which makes this the optimum shape - that double flanging for instance, or is it just a case of "we've always made them that size"?

I’m not an engineer but I practically live for this kind of info. There was another opening method that came after the throw away tab. It involved to two separate openings, sealed by two round, raised discs; one was large diameter, the other small diameter. The can was opened by first pushing the small disc to easily vent the gas and it would afterwards serve as the air intake to permit the contents to pour smoothly. The larger disc was then pressed and it became the port through which the liquid was poured or drank. There were no detachable parts but I suspect there were complaints about the difficulty of opening the initial disc. I think Pepsi brands used this design but it was eclipsed in a few years by the current perfected opening method. In the province of Ontario pop cans used to be steel and only 10 fluid ounces, but beer cans were 12 fluid ounces (Imperial fluid ounces). A longer video could be made concerning glass pop bottles and their rapid transformation altogether to plastic. The glass bottles were usually 26 imperial fluid ounces and they had to be returned to a store that carried one of about 3 pop distributors (Coke, Pepsi and Wilson’s or Canada Dry) operating in and around Toronto into the early 1980’s. To make matters less efficient, the bottles were packed into large wood or plastic carriers of 12 bottles and grocery stores would have to collect these, distribute the empties into their correct packages, and then stack and store them until the pop truck came once or twice a week. No wonder pop was relatively expensive back then. I recall a package of 24 , 12 ounce cans of Coca Cola selling for about $7 Canadian dollars early in the 1980’s and then....Dave Nichols opened up the competition somehow, and prices of pop crashed and have still not recovered. The bottles of pop back then were making a fortune selling sugared and coloured carbonated water...and now, I suspect sales of pop are declining as the market becomes more sophisticated.

"It's Engineering not Grade School." I am a Registered Professional Engineer, ME, AE and MME. I hold several US Patents which have been prosecuted outside the US and resulted in 946 Patents in 51 countries through out Europe, Asia and anywhere else worth having Intellectual Property. I worked for a major Defense Contractor in Aerospace doing Design and primarily Ordnance work before striking out on my own. The Metric System exemplifies itself with its embodiment of the use of a base 10 system. I prefer using metric in certain applications but as a Nation, the use of the English System works better because our World has its roots in it. Pound, Foot, Mile, Gallon, Ounce are here to stay. And guess what, as long as houses are sold by square footage, speed limits are mph, football fields are in yards, gas is in gallons and women's measurements are given in inches nothing is going to change.... you pompous ass.

I used to recycle cans until I found out the government via NASA was using the cans to create a powdered dust that was then distributed into the atmosphere above us in crop duster planes to create weather disruptions like rain and heat and storms , they called it free riding on our grandchildren almost 50 years ago, its known as chem-trails. They called it free riding on our grandchildren because it was never tested to see what effects it would have on humans, children, asthmatics , animals or the environment. So if you thought you were doing a good thing for the environment think again.

Twister051 (15 days ago)
I'm not an engineer but this is sooooo cool! I never ceased to be amazed at how stuff is designed. Even the fact that I flat, circular disc can be shaped into a smooth, topless cylinder, I find amazing. How does the metal become shaped but not wrinkled? Sure, through the progressively different tooling but I would think it would still cause minor wrinkling but it doesn't. Incredible.
Asher Christner (15 days ago)
My calc teacher asks: why are dimensions of the can not so that the height equals the diameter? These are the dimensions that maximize the volume vs surface area of a cylinder. Is there some business strategy afoot?
Xavier Krebs (5 days ago)
Because the weight/thickness of the side wall is much smaller than the top/bottom of the can, thanks to the mouldering process.... so it's more economical to keep the top/bottom smaller...
Joseph Wagner (15 days ago)
This video is great, thank you for the interesting content! I was surprised you didn't mention how the score line forming the mouth is asymmetric such that, when pulling the tab to open the can, the mouth starts shearing on one end of this line and continues until fully open. The tab itself is also angled toward the starting point of the shear. If the tab and mouth were design symmetrically, you'd be attempting to shear the whole mouth profile at once, requiring greater effort pulling the tab. Another overlooked feature that makes beverage cans easier to open.

Why a cylinder? 0:20 Sphere: + Least Surface Area, e.g Least Material + No Corners, no weak points - Will Roll Off the Table - 74% total volume taken up, leaving 26% of void space (issue when packing) 0:52 Cuboid + Sits on a Table - Awkward to drink from - Edges are a weak point, requiring thick walls, e.g more material + Packing Efficiency 1:17 *The Cylinder* Top- Like a sphere Side- Like a cuboid 1:31 Middle Packing Factor 1:38 *How Soda Cans Are Made*

But when/how does the sealing compound get injected/applied? The pockets aren't made until the seal is completed but then I don't see a way to insert the sealing compound. Maybe the liquid compound (that later as you said hardens, turning into a gasket), is inserted at the same time the seal is made? But that sounds hard to do/sloppy. Ooo maybe its a thick paste that is applied to the walls of the seal so it allows time for the curling and pockets of the seal to be made without spilling? But no you said it's applied as a liquid not a paste hmm....yup, I'm stumped.

Outstanding presentation. I have always been enamored by the design of the self contained pull-tab, and appreciated the engineering theory behind it. I knew someone who worked at Ball Aerospace who worked in artificial intelligence, and helped design a quality control process to verify the screening of the can and thickness of that insulating layer at very high speed. He showed me some of the prototype equipment. It never occurred to me so much thought and technology went into the manufacturing of a can.

I know an old man that was a machinist that made punches for the can. His prized possession is a punch he spent a year making. Claims it is about as perfect as you can machine this object and has been offered money for it. Thick tool steel cylinder with perfect surface. He had it in a wood box and wouldn’t handle it with bare hands.
