(via) We take the design of the standard aluminum beverage can for granted, but it’s actually a highly complex feat of engineering genius. From the Engineer Guy:
Bill details the engineering choices underlying the design of a beverage can He explains why it is cylindrical, outlines the manufacturing steps needed to created the can, notes why the can narrows near it lid, show close ups of the double-seam that hold the lid on, and details the complex operation of the tab that opens the can.
