lol, i was just watching the new keynote when phil schiller (i think) talks about the new friction stir method. Obviously alumin is an elements, and therefore doesnt have molecules. It makes me either a, think he isnt the brightest guy in the world. or B, he has no idea what he is talkling about, and therefore you shudnt trust him. just gving a little input. btw if u want to see it it is at around 30 minutes exactly of the keynote.
