That would be the one in Aluminium!
Seriously though, any idea where that "i" disappears to in the pronunciation?
...the same place it goes in the spelling - the Atlantic Ocean! We don't add the extra "i" over here. BTW, didn't we invent aluminum, anyway? Therefore, our spelling and pronunciation are correct. I think we'll have to invade you over this dispute! Oh, I forgot...GW Bush is no longer our President...
