We might build a 12'x16' equilateral A-frame...

You used the word "Might" 8 times, "Could" 3 times, "If" 3 times, with a
"Maybe" and "Somehow" once each.

Thank you for counting.

"Could" it be that you "Might" be proposing that "If" "Somehow" you
"Maybe" actually built one you could prove your point without using
those words that only confirm that you are in fact just guessing.

The only big risk is the plastic pool losing strength at 130 F, and there
are solutions for that. I go overboard on the "mights" to avoid ignorant
people like you raising angry challenges to 300-year-old settled physics.
