Ok, bit of a bragging moment here: my grandpa, with two other gentlemen, created the process for machining seamless cans that is described here. Before them, cans had a lead seam in them. They discovered that you could draw down the aluminum and stretch it to form cans in one piece. He also invented the process for creating the bottom of soda cans, and his friend invented the modern tab on the top of soda cans.

That's pretty damn awesome. Behind everything we take for granted, there's someone who slaved over it and brought it into fruition. Thanks for sharing!

eh, I just don't feel like the writer understands or cares to explain how that whole process is actually detrimental to the world despite the fact that it "unites" it. Coke is just addictive sugar water that does nothing for anyone. When has coke given you something other than diabetes?

Kevin Ashton fails at pointing out the impact of this collaboration. Couldn't all of these talented people that made such a sophisticated product put their energy towards something.. I dunno, useful?

I read it and then thought "Why Coke?" That's the story of every manufactured product assembled from multi-sourced vendors. It's not news, and it's not unique to Coke. If you think it is you'll probably have an orgasm when you learn how pencils are made.

I'll go ahead and ask how pencils are made.

Right, this same story gets re-hashed every few months on the popular news sharing sites as a way to "blow people's minds" and there is never a shortage of people who lap it up. It is amazing how stuff is made, but not mind-blowing.

I think about this occasionally. Everything that you see that isn't "nature" was explicitly designed by somebody (and most likely a large team of somebodies). Its truly mind-boggling.

>>The top of the can is then added. This is carefully engineered: it is made from aluminum, but it has to be thicker and stronger to withstand the pressure of the carbon dioxide gas. Eh? The pressure is greater at the top of the can?

It may also be a result of greater stiffness required for the captive pop-tab opener to work properly.

There's an interesting Slate article[1] about the complexity of what appears to be a such a simple feature; in order to achieve the force necessary to rupture the can opening, the tab pivot transitions between a first and second class lever. There's a good video somewhere showing the principles, but I can't seem to find it.

Returning to the 'pressure' argument, recall that most drinks cans have a domed bottom which provides comparatively greater strength than the flatter top.

By that logic, candy is pointless and we should get rid of it?
