Thanks, this was really interesting. I remember in the early 70's the pull tabs were a huge problem for lawns and playing fields, as lawn mowers would chew them up into dangerous shrapnel. There were a few other opening systems, like the "button" system used on early Coors cans. If you don't appreciate how well the opening lever works on cans, try opening one where the lever has broken off. It can be done, but you'll need a hammer and some towels to clean up afterwards.

Necking, doming. Even some bleeding This turned more x rated than I expected. Lol Interesting video :)

3:01 I don't understand how this uses less material. Where can I read more about that?

Plus wouldnt the dome mean there is less condensation(or whatever) that comes from the can.

Why was the neck introduced? I still remember soda cans, without that tapered neck. What is the reason for this added complication?

Fascinating. Thank you so much.

There was another type of opening device for cans other than a ring pull. It was a pop top with two circular depressions, a small one to vent and a larger one to drink from.

It's also worth noting that with the 1970's pull tabs many people would pull the tab off, then drop it into the can and then drink the beverage... and sometimes choke on it or otherwise injure themselves.

I have a question, i learned during my highschool years, that the cans overall shape and size is not the most efficient in means of volume vs. material, is this for best ergonomic grip or is there another reason? by the way, love the channel, best regards, Denmark.

Ahhh... the glorious pop can pull tab... Shake the can up and you had a portable geyser waiting to erupt on your command to douse your unsuspecting friends... Walk through the little league baseball diamond parking lot and you could find ENDLESS amounts of the pop top rings to use as "FLINGERS" 9:08 ... use the triangular tab as a lever and pull the ring back after hooking it to the tab... when released it would go sailing off like a frisbee. Get about 100 of them and go to the top of the bleachers and you had a good 2 hours of fun seeing how far they would fly and seeing who could fling the ring the farthest. Simple kid fun from the early 1970's.

I collect odd unopened cans and I just found one without a number on the bottom. The rest of my cans have a 2 or a 1 along with something between 1 and 9. It's a little strange. The can is a 'Be one of a kind', football related, Dr.Peper, with the expiration, May 30 2016.

What a great video which has made me a new fan of Engineer guy! I always assumed the changes in cans over the years were cosmetic rather than for efficiency. I have a deeper respect for can design.

Nice video. I was hoping to learn how the edges of a pull top cans can be made so that after tearing off, they present no sharp edges.

it is a waste of a precious metal. a waste! and also because of the fluids that are contained within. those are 100% unhealthy and cause all kinds of diseases. it is worth taking about those diseases rather than the god damn can.

My dad was an engineer and he worked for years in the production of cans. Metal, and then aluminum. He worked For Continental and, when they changed over, he worked for Crown. He was involved in making improvements to the machines that produce these cans. He passed away about two years ago. He would have loved this video. Very well done.

You did a better job of lecturing than some esteemed university professors. I love YouTube education like this. I would encourage citing scholarly sources even if all the viewers cannot reach them as this improves credibility. Thank you!

For can-themed cartoons, there's Akikan (”Empty Can”), the insane story of a high school boy whose can of melon soda magically transforms into a human girl. More "akikan" girls begin appearing, each of them needing to be infused with carbon dioxide from their respective drink types to survive. The akikans were created by the Japanese government to determine whether steel cans or aluminium cans are superior. The akikans must battle each other until only the strongest type is left standing.

Sorry, the can is a poor design. Everytime i want to get the last drop i have to break my neck 180 degrees backward. Even then the ledge on the top of the can prevents me from getting all my dew.

Also, with the modern top, the can's tab can be rotated and the hole used to keep your straw from popping back up from within the can.

I still don't understand the dome on the bottom? They do that to reduce material? But the flat part is already there.

Problem is, some top of the can are dusty at storage. After cleaning with water, it difficult to dry using cloth.

I guess when you know what you're talking about, you can make anything sound _amazing !!!_
GreatWhiteNiko (10 days ago)
Yes, ain't that an amazing invention? The tab ends up in the drink. As you drink the drink spills on the inside channel. Dirt on the top of the can is now mixed with the drink. Not a single person on Earth ever washes an aluminum can before use. But no, I'm gonna be excited about levers, fulcrum, and "engineering". Let's not even go into the organic details of Alumin(i)um production, the plastic that lines the can, and the paints that bring joy to our eyes. That'd be bad taste. To wrap it up - let's forget the 3 tablespoons of sugar in every can - if you are lucky to be real sugar that is. Only you know that if you drink sodas you drink 3-5 a day, right?. Daily you swallow 9-15 tablespoons of sugar. Mix 15 spoons of sugar in water and drink them - that is what you do every single day after converting the cool lever 2 into 1 a few times a day. But nobody else knows so it's ok. Freaking 2 fistfuls of sugar every day. I think I feel sick now... Enjoy!
