I made it through four NYC summers without AC, with only a handful of uncomfortable summer nights. But the record-breaking heat wave this year seems never ending, and I finally gave in and bought a little window unit for the bedroom, which is now referred to as "the icebox." (the rest of the apartment is still pretty unpleasant.) I'm sure it will quadruple my energy bill, but it sure is nice and chilly in here now. For the record, I didn't buy the AC until I had tried absolutely everything I could think of to cool off, including this DIY air-cooling contraption.
As you may have guessed, it did not work.
