I hope so. I literally was cycling through “eggs” and weapons and landed on it. I must have read either a Straight Dope thread or article years ago and it fell into place. If it is wrong, it’s a pretty satisfying alternate solution. I’m pretty sure my understanding is correct and fits.
Good one. Now I know something new.
Wow! Very nice, indeed.
Gabe worked in a factory and one day, he decided to inspect the inside of a tank that had only been used to hold fresh water. It was upright and had a manhole entry in the top. It was 4 meters deep and had a diameter of 2 meters. There was 15 cm of water on the bottom. Shortly after entering the tank, he keeled over and died. Why?
Was his death caused by his entry into the tank?
Did he drown?
Did he asphyxiate?
Did he die due to temperature extremes?
Was the water liquid?
kk
Was there an unexpected amount of Nitrogen?, Argon?, Helium?, Butane?, Propane?, Carbon Dioxide? in the tank?
If not, was there an unexpected amount of some other gas in the tank? An unusually low amount of oxygen in the tank?
Did he close the top?
Did someone else close the top?
Did the top automatically close for some reason?
KK
Did temperature play any part in this incident?
No.
Was there low oxygen due to a chemical reaction?
Was there low oxygen due to absorption by a substance of the oxygen? (Which I guess is also a chemical reaction)
Did a physical mechanism cause there to be low oxygen?
Did a non-human living substance/creature create a low oxygen environment?
kk
Had Gabe been walking in something before entering the tank? Did it stick to his boots or clothing? Did that something react with the water drawing the oxygen out of the air?
Was Gabe smoking?
Did the tank contain normal oxygen levels as of when Gabe entered it?
By “normal”, I mean levels typical of sea level outside on Earth.
And a physical mechanism causing low oxygen could, for instance, be a vacuum pump.
No to all.
kk
Was Gabe on Earth?
Yes.
Was the tank under pressure when he entered?
