What do I know?

I am stuck on the Science Channel.

I am watching a show called “How It’s Made”. So far I’ve learned how to make aluminum foil. Did you know that aluminum foil starts out as an 18” thick block and is continually pressed until it is down to the desired thickness?

I am reminded of the series Hitchhiker’s Guide to the Galaxy. In one of the books (can’t remember which) Arthur Dent is stranded on a planet more primitive than Earth. Though he knows all about electricity, gas powered engines, televisions, microwaves and such, he unfortunately has no clue how any of these things work.

His contribution to this new society – he becomes a sandwich maker.
