Keelia, I've learned from your list about trash pumps and cyanobacteria.

Trash pumps don't pump trash, and cyanobacteria are not the color cyan (which I know from printer inks—four-color separation, and dot-matrix printers both).

"Trash pumps are designed to pump large amounts of water that contains hard and soft solids such as mud, leaves, twigs, sand, and sludge. Most devices are portable, heavy-duty centrifugal pumps that feature deeper impeller vanes and larger discharge openings than other pumps"

I LOVE the internet.

Trash pumps are as to water pumps as shop vacs are to vacuum cleaners (I think—correct me if that's wrong.

And the code for that in logical notation might be trash pump : water pump :: shop vac : vacuum cleaner

I learned that notation in school but not FROM school.  I remember it from standardized tests, and I took more of those than most people, not knowing it wasn't normal.  Turns out our school was part of somebody's study, for a few years, and from about 4th grade to 9th, we were tested every year, where as others in our state who weren't in our part of that test study were only tested in twice in that time.  Anyway, one section of the long battery of tests we had was analogies of all sorts—numbers, words, physical forms.  I LOVED THOSE—shapes, and puzzly-looking widgets.

Nice list, Keelia.  Things I can't do.
