I just realized something, and what does one do, in 2004, when they realize something? Why, blog it, of course.
I still call it ‘tin foil’. Exclusively. Never ‘foil’ and certainly never the truly correct ‘aluminum foil’. No one even sells ‘tin foil’ anymore, do they?
Why do I (and many others, from my casual straw polling) still refer to aluminum as tin when it comes to foil?
