Living in the Chimney.
Since I am now living on the top tier of this dorm I have wondered why, when I opened the window, no cool air came in despite all the snow on the ground.
Holding a strip of toilet paper by the open window clearly shows the air flow is going out.
Yes, of course, hot air rises!
Since my door is full of holes and there is no door at all for the bottom six inches, my only other choice is to close the window and have the minimal air flow from the 8" by 4" vent that I assume blows air, and then hope some gets forced out through the holes in the door.
Leaving the window open draws all the germs and the cigarette smoke from the cigarettes-you-are-not-allowed-to-smoke-indoors right past my face on its way out the window.
Oh, well, I know I am in prison, so suck it up. Thanks for the support.
