I have no idea what this has to do with HN, but, one of the best "life hacks" I've ever learned was from my Iraq tours: evaporative cooling.
If you're outside on a hot day and your drink is hot (in our case, it was palettes and palettes full of bottled water), get a wash rag or a skivvy shirt wet, wrap it around your drink container, and let it sit out in the sun. In a little while, voila, cold drink.
Apropos of nothing.
- SiVal 14y agoIt works better in the shade, and best of all in the shade exposed to a breeze. You don't need to warm the water in the rag to evaporate it. It will evaporate in the dry air, even if cool. Putting it in the sun raises its temperature as the evaporation lowers it. If there's a nice breeze, evaporation will still win, but it will get cooler if you don't add energy at the same time you are removing it.
- mattdeboard 14y agoThat's it, it's been awhile (6 years... wow). Thanks for the correction. Heat + breeze (even if the only breeze is warm).

- Nick_C 14y agoWhen I was a kid growing up, it was common to see vehicles from the outback with a square water bag suspended from a frame in front of the grill. The bag was canvas and leaked slightly--enough to keep the outside moist so that the contents would chill from the wind as the vehicle drove along. The water was nice and cold, just right for a hot summer's day. Oddly, I don't see them any more. Perhaps there are enough roadhouses along the highways that anyone can pull in and buy a chilled soft drink when they want.
