Nice video on the design and manufacturing of aluminum drinks cans here: https://youtu.be/hUhisi2FBuw The whole thing is pretty ingenious, but the way the internal pressure helps vent the can while the tab is acting as a second class lever, then as soon as it’s vented becomes a first class lever to push the scored section of the top into the can — that’s great engineering. |
