It
is so common and easy to use, it could be overlooked. But look at
it. A metal so thin it is perfectly smooth, flexible, and strong.
It comes off the roll easily. It’s flawless.
I
remember aluminum foil’s predecessor, tin foil. It was not so uniform and
flexible, and not as cheap. Tinsel on the Christmas tree was made of tin
foil. Metal. I know it was metal because when it fell off the tree
and landed on the train tracks, it would spark and short circuit the
train. Tin foil was precious enough that we would recover it from the
tree after Christmas, piece by piece, to be put away for use again the next
year.
But
back to aluminum foil. The aluminum gets mined, refined, and rolled out
into these fine flexible sheets for our convenience, and it’s so inexpensive,
when we’re through with each piece, we just crumple it up and throw it
away. Amazing.
